No. I wasn't born like this. Her, you fight for, lovely Freya, the daughter you barely know. But there was a time where you knew me as your son! A time before all the disappointments, the revelations of betrayal. There were moments where all you had to do was be my father! And even then, you despised me, didn't you? I want to know why.
Klaus was first mentioned in the second season of The Vampire Diaries in Rose, during a conversation between Rose and Stefan Salvatore. Rose warns Stefan about the Original Vampires which led to Elena Gilbert believing Klaus was the oldest vampire in history. Elijah later mentions that Klaus is a recluse and trusts very few people, usually only in his inner circle.
For over a thousand years, Klaus had been trying to break a curse placed on him. He created the myth of the sun and moon curse in order to find the moonstone and the Petrova Doppelgänger, both of which were needed to break the actual curse. His goal was to liberate his werewolf side so he could sire his own super species of vampire-werewolf hybrids.
In 1492, he finally got the chance to break his curse when he met Katerina Petrova, the final piece necessary to break the curse. However, Katerina managed to foil his plan to use her in the sacrifice by turning into a vampire. For the next 500 years, Klaus searched for a way to break the curse without the doppelgänger, forcing generations of witches to help him. During his search for a way to break the curse, Klaus hunted down his family and neutralized them. He also hunted Katerina, who had escaped him and stolen his moonstone. However, it should also be noted that he was also on the run from his step-father, Mikael, as Klaus had an abusive childhood.
Besides his family, during the 1920's, Klaus formed a strong bond and brotherly relationship with Stefan. He then met with the vampire, Caroline Forbes, and starts to care about her eventually falling in love with her and tried to win her love, after a long time they are now friends. In New Orleans, he has a father/son bond relationship with Marcel whom he works with in ruling New Orleans until Klaus discovered his treachery for bringing Mikael to New Orleans. They reformed their friendship when Marcel saves his daughter and now they work together to bring down their enemies. He also truly cares about the bartender Camille O'Connell, whom he has a close relationship with.
Klaus is also the first undead creature in the history of the series universe known to have impregnated a woman. He was under the curse of the Moonlight Ring's forged with his blood, meaning that every werewolf who draws on them to prevent their transformation on the full moon will be drawing energy from Klaus himself. The Moonlight Rings forged from Klaus' blood have been destroyed so he no longer is weak every full moon.
Niklaus was born to Esther and Ansel in a small village that would eventually become known as Mystic Falls. Niklaus has six half-siblings and a step-father named Mikael, a Viking warrior and wealthy landowner who moved with his wife, Esther, to the New World after their home village was devastated by a plague. Mikael believed his beloved first born daughter Freya was a victim of it, not knowing she was taken by Esther's sister Dahlia as payment for a fertility spell to let Esther have children. Klaus was close to his family with the exception of Mikael. Mikael was inordinately hard on Klaus, having become an aggressive, violent, and strict man after he thought Freya died, always trying to teach his children to survive so he would not lose another child. In Klaus' case, Mikael was abusive to him for his impulsive and reckless behavior, justifying that his punishments would make Klaus stronger, but Mikael was only ever disappointed in everything Klaus did an beat him repeatedly through his mortal life. Elijah said that, as a mortal, Klaus was full of love and wanted to be loved in return. After becoming an Original Vampire and werewolf hybrid, his amplified temper and emotions, along with psychological damage of Mikael's cruelty, turned Klaus into a violent and cruel person, much like his step-father Mikael. Many years before, his mother had an affair with a man from the neighboring village, whose inhabitants were known to be werewolves.
Once as kids Elijah takes Niklaus into the woods to teach him how to hunt. Elijah encourages his brother,
stating that his aim has been improving, when he misses a shot. But, Mikael intervenes and scolds Elijah for encouraging his brother and snatches the bow from Niklaus stating that he wasn't man enough to hold a weapon. Niklaus tries to apologize, but Mikael sees him as a weakling and starts kicking him. Elijah tries to stop his father from hurting his brother but he is scared off by Mikael who stated that if Elijah intervened he would be next.
He was once beaten, half to death, as a boy, when his father's blades went missing. In the days following the incident, Rebekah was particularly kind to him which Klaus later realized meant that she had been the one to take it.
Niklaus and all his siblings used to play in the woods, when they were kids, showing they all loved each other dearly. He even stayed awake, to comfort a scared Rebekah by holding her hand, during a stormy night and giving her a wooden carved knight, which he made for his father stating that it will protect her, something that has been kept safely by Niklaus to this date as memento of his childhood.
Esther found little Klaus in that woods once when he was hiding before Mikael. He was afraid so she gave him a necklace which should protect him and remind him that Esther will be always with him. A few years later, Mikael hurt Klaus in the woods during a fight between them. Esther helped Klaus to heal. Klaus told her about the fight and that Mikael wanted to take him the necklace.
In the episode, Every Mother's Son Klaus found out that the necklace made him weak because of Esther's spell - she didn't want him to be strong, kill somebody and became trigger the werewolf gene.
Both Niklaus and Elijah were in love with Tatia, even though she had a child with her husband who died in battle. They both vied for her attention and even had arguments and blows over her, she eventually chose to be with Elijah. Centuries later, Elijah finally told Niklaus he killed Tatia. Niklaus was very angry with Elijah over this, but he chose to forgive him. They later found out that Tatia's blood was used for the The Immortality Spell placed on them.
Niklaus was once slogged by Mikael severely for taking his knife for carving chess pieces. When Elijah comes in and tries to stop his father from beating Niklaus to death, he gets pushed back. Then, Rebekah intervenes, by threatening to kill their father with a sword if he doesn't stop beating Niklaus. Mikael snatches the sword from Rebekah and leaves in a rage.
When Niklaus and his brother Henrik went to see the wolves transform,
Henrik was killed by one of the wolves and Esther performed a spell (called The Immortality Spell) which transformed Niklaus, his siblings and his step-father into vampires.
When Niklaus made his first human kill, his werewolf gene was activated and he became hybrid, thus revealing Esther's infidelity. Mikael then hunted down and killed Niklaus father and his entire family, not realizing that doing so would ignite a war between vampires and werewolves that has been perpetuated across the ages. Soon after becoming a Hybrid, Mikael had Elijah help him restrain Niklaus and Esther to use her Dark Magic to place a curse on him; which forced his werewolf side to lie dormant and then rejected and abandoned him. In retaliation, Klaus murdered his mother and framed Mikael for the act.
After killing Esther, his family scattered and Niklaus stayed behind with Rebekah to bury Esther. Rebekah promised to never turn her back on him, like Esther did and so did Elijah. They swore to each other they would stay together always and forever.
Italy, 1114 A.D.
Klaus was with Elijah and Rebekah in 1114 AD Italy when they met a man named Alexander, a vampire hunter who was part of The Five. They spent a lot of time with him -- the brothers in order to discover his plans for killing vampires and Rebekah because she loved him. Alexander did not seem to suspect them; they wore their daylight rings, allowing them to walk in the sun without burning, unlike the vampires whom Alexander killed on public display. However, when Klaus and his siblings were invited to a party at Alexander's home, the members of The Five daggered them in their sleep. Klaus, with half werewolf lineage, could not be neutralized by the White Oak Ash Dagger and upon awakening killed all of The Five, including Alexander. He undaggered his siblings (except for Finn) and found out from Rebekah that the weapon Alexander had told her about was a "cure" for vampirism. As a result of slaying The Five, Klaus was forced to endure 52 years, 4 months and 9 days of the Hunter's Curse - torturous hallucinations that haunted his dreams and every waking moment in an attempt to make him kill himself, but unable to, given his near-indestructible state.
According to Elijah, Klaus has lost much of his humanity, hiding his loneliness with cruelty and anger.
Klaus was an English nobleman during the late 15th century when he met Katerina Petrova, the doppelgänger whose appearance he had been awaiting for five hundred years. Planning to use her in the ritual, he had kept her entertained until the full moon, but she learned of his plan before it could take place and escaped, taking the moonstone with her. As she fled, she encountered a vampire named Rose, whom she tricked into turning her into a vampire, thus ruining forever Klaus' plan to use her to break the curse. After Katerina turned into a vampire, Klaus assumed that her family line ended with her and that his chance to break his curse was gone forever. In retaliation, Klaus traveled to Bulgaria and murdered Katerina's entire family for her defiance.
Cadiz, Spain, 1702
In 1702, Kol's violence in Spain drew too much attention and brought Mikael, straight to the family, burning the country in his wake. While the flames drew closer and Mikael beheaded Klaus' horse,Theo. Elijah and Klaus searched for Kol while Rebekah brought the daggered Finn onboard a ship to flee from Europe. They found him in a tavern where he drank and feasted on humans carelessly. Despite their warnings of Mikael's coming, he refused to flee. When Klaus and Elijah insisted, Kol attempted to resist them but was subdued by Elijah as Klaus pulled out one of the white oak ash daggers and successfully neutralized Kol.
New Orleans,18th Century to 20th Century
Having fled the Old World, escaping Mikael , Klaus, along with Rebekah, Elijah, and their daggeredbrothers sailed across the world, through the Mississippi River and arrived in New Orleans, 300 years from the present. Upon arriving off the coast of New Orleans, they slaughtered all the men who boarded their ship, but left one alive to question and carry their luggage.
In 1720, Klaus and Elijah helped the Governor in building the New Orleans' first levees.
In 1820, Niklaus, Elijah, and Rebekah were living in New Orleans at the Governor's mansion; and were paying the governor in gold to keep quiet about the existence of vampires. One day the Governor threw a party for the Mikaelsons. Rebekah went up stairs with the Governor's son, who she wanted to turn. Rebekah went to Elijah with the Governor's son and asked if she could turn him, to which Elijah suggested it wouldn't be a wise move to turn the Governor's son into a vampire. In that moment, Klaus took the Governor's son and threw him off the second story, killing him immediately. Klaus and his brother attended the funeral of the Governor's son, when Klaus sees a man whipping a child. Klaus saves the child; and decides to care for him. He names the child Marcellus.
He later meets the Governor to ask for Marcellus' freedom and chokes the Governor's neck until he grants the freedom. Niklaus asks Marcel about his father and quotes that family can be more than just those with whom they share blood and that they can choose. Marcel looked touched by his words.
In 1820, Klaus is seen challenging a man in a duel; but Klaus wins the duel. Elijah then becomes a little worried and asks Klaus if it is not enough, that he has slaughtered dozens in just these past several weeks. Klaus explains that a city littered with bodies will surely travel the oceans. Elijah asks his brother if he wants to bring their father upon them; but Klaus tells Elijah to relax. Klaus then explains that he has sent rumor that the bodies are a result of the witches seeking blood sacrifice for their rituals. Elijah is shocked because he is in love with a witch named Celeste; but Klaus isn't concerned. Elijah takes a revolver and shoots at Klaus, who groans with pain. Klaus sees that Elijah cares about Celeste and warns that they're rounding up the town's witches as they speak.
Klaus grew jealous as Marcellus grew closer to Elijah rather than him. Feeling lonely, he undaggered his younger brother, Kol, so he'd have someone to have fun with. The two began happily causing chaos across New Orleans, even slaughtering an entire tenement building for fun. When Klaus revealed that he'd choose Marcellus over Kol, though, Kol grew angry and threatened to turn Marcellus into a vampire. Klaus, realizing his brother was too wild to control, daggered Kol yet again.
By 1835, Marcel and Rebekah spent practicing fencing, when Marcel was finally an adult, he could best her in a duel he attempted to make his move on her only to be stopped by Klaus. Despite pleading with Klaus to let him be with Rebekah, Klaus still shot him down and forbid him from pursuing her. However this did not stop Marcel from trying again and making out with Rebekah. They were abruptly torn apart physically by Klaus who decided to punish them by daggering Rebekah.
In the same year, Marcel gets shot by the the Governor while trying to free some slaves. A dying Marcel forces Klaus to turn him into a vampire or let him die as a human. Niklaus against his wishes, gives in and fulfills Marcel's desire to become a vampire.
In 1887, Klaus undaggered Rebekah revealing he had left her daggered for 52 years. When she had asked to see Marcel, Klaus sadistically revealed that he gave Marcel an ultimatum. Either live a long human life with Rebekah and die or become a vampire, but stay away from Rebekah. He chose the latter, even walking into the room as proof, devastating Rebekah.
In 1918 Klaus wanted to convince Marcel not to fight in World War 1. Marcel left New Orleans anyway.
Later Klaus visited Marcel on the war front to entice him to drink blood of young ladies. At the same time he offered Marcel return to New Orleans. Marcel was starving but he refused Klaus' offer again because he didn't want to leave his men.
In 1919, Klaus tried to make arrangements with werewolves in the city, so his rule could remain hidden. But their meeting is soon interrupted by the witch Alphonz Bellatunde Delgallo, also known as Papa Tunde, who demands to know how would it benefit for the witches. He demands a tribute as he thinks he is also the king in this city and brings them the head of the mayor who he has killed. Klaus doesn't like it and decides to find out who this enemy is. Klaus befriends him to find out his weaknesses so he could destroy him. With help of the Marcel (who just returned from WW1) he finds out that Papa Tunde channels two twin witches who always accompany him and kills them to get rid of this rival.
During this time, Klaus was very critical of Marcel and Rebekah's relationship, and they were determined to remove Klaus from their lives, and unbeknownst to Klaus, used a witch to call Mikael to New Orleans.
Six months after this, Klaus and Elijah attend a local club underneath the Opera Theater, and Klaus flirts briefly with Lana, the "Werewolf Queen" and owner, before he and Elijah contemplate the unification of New Orleans. Elijah tells him they worked together to build up the city, but it was originally Niklaus' vision.
Sometime later whilst sharing a drink with Elijah, Klaus notices Marcel and Rebekah attempting to convincingly avoid each other, as he stands, Elijah tries to pull him down to refrain him from causing trouble.
Instead of condemning the pair, Klaus admits that as they move into the new era, attitudes must change. He toasts to Marcel and Rebekah, that they find joy in each other and that he has killed Rebekah's lovers to protect her from a broken heart if they have to move. However they are now home and he wants her to be happy.
After a morning with Lana, she proposes tickets for the Theater that night. Rebekah and Klaus are later seen in a box at the Theater, and Rebekah heads towards the lobby to find Marcel. As Klaus is left alone and the curtain about to lift, Mikael appears behind him, poking his back with the White Oak. Mikael taunts him over the word "father" and that his real father would be just as embarrassed before telling him his plan. After Klaus demands Mikael just kill him, he is proud of his achievements in creating the city, Mikael taunts death will come, however afterwards he will stay in New Orleans.
He will stay long enough to make sure everybody who remembers Klaus will be dead, and it would be as if he never even existed. As Klaus mulls this over, the curtains lift and Mikael announces he made some changes, sarcastically baiting he would love them. The audience applauses and laughs, compelled by Mikael as the curtain reveals Lana, impaled with a stake and Marcel is staked to a cross, barely conscious.
Klaus tries to save Marcel however he is thwarted by Mikael, and Rebekah intervenes only for Mikael to stab her and push her aside. Only when Elijah appears, they decide to run, that it was too late to save Marcel who Mikael was feeding on. As they flee, Klaus feeds Rebekah his blood to heal her as they hear Mikael approach. She is devastated at Marcel's apparent death and reveals it was her fault. Klaus denies this, instead apologizing to her, saying this was his fault, and as the Opera burns to the ground ahead of them with screams rippling from inside, that he thought they found a home. Elijah tells them to leave, that he will hold Mikael off. After hesitation, Klaus grabs Rebekah and the two leave New Orleans.
During the 1920's, Klaus and his sister Rebekah were on the run from Mikael, who they had been running from for a 1000 years. The siblings were in Chicago in 1922 where they met the vampire Stefan Salvatore, whom Rebekah fell in love with. At first Klaus hated Stefan, but he grew to like him once he discovered that Stefan was a Ripper and they became good friends.
One night, the speakeasy they were at was attacked, apparently by the police, though it turned out the raid was led by Mikael. Before he left, Klaus compelled Stefan to forget him and Rebekah. Later, when he and Rebekah were about to leave Chicago, Rebekah told Klaus that she was tired of running and wanted to be with Stefan. Klaus then forced her to choose between him and Stefan; she chose Stefan. Afraid of being left alone, he neutralized his sister with a White Oak Ash Dagger, then took her body with him in a car and left Chicago.
Throughout The Vampire Diaries Series
Isobel Flemming, a vampire working with Katerina Petrova (now known as Katherine Pierce) and who also happened to be the mother of the Third Petrova doppelgänger, was trying to find Klaus and ultimately succeeded by getting close to a member of his inner circle. Klaus found out what she was up to and compelled her to tell him what she knew. When he learned that she was working with Katherine and that the rumors about a doppelgänger in Mystic Falls were true, he decided to use her in a plan to capture Katherine, the moonstone and the new doppelgänger.
Along with Klaus' trusted witch, Maddox, Isobel made Katherine believe that Klaus was willing to pardon her if she delivered the moonstone and the doppelgänger to him. While Katherine found the moonstone, Isobel helped Maddox capture her former husband, Alaric Saltzman. Katherine and Isobel then captured Elena at which point Isobel revealed her true colors and Maddox captured Katherine. He then ordered her to let Elena go since Klaus didn't need her yet. Maddox then transferred Klaus' spirit into Alaric's body so that he could spy on Elena and her friends.
In The Last Dance, Klaus interrogates Katherine for information about Elena and her friends and learns that a witch Bonnie Bennett could be a danger to him, so he decides to kill her. Still pretending to be Alaric, he attacks her at the 60's decade dance by compelling several students. Finally cornering Bonnie, he forces her to use enough power to kill her, until she apparently dies. He doesn't realize that she has faked her death to protect herself and Elena.
In Klaus, he has Maddox and his other minions, including Greta, bring his original body to him so that he can return to it. While they are doing so, he sets up a contingency plan by threatening Jenna's life. As Stefan stops him from killing Jenna, Klaus tells him that it would be easy for him to take his revenge if Elena tries to stop him from breaking the curse. At the same time, Elena learns from Elijah the true nature of the curse and why Klaus wants to break it. He is then released from Alaric's body and returned to his own by Maddox and Greta.
Klaus goes to the Mystic Grill to remind Damon not to do anything he will regret. Damon asks if he can postpone the ritual, but Klaus says he has everything he needs and the ritual will happen. He warns him not to screw it up if he wants to live. Klaus returns to Alaric's apartment and is immediately suspicious of Katherine. He compels her to tell him what she has been doing but, as she is taking vervain, she is able to lie.
He is still suspicious and 'compels' her to take off her bracelet, walk to the window and stand in the sunlight. In order to keep up the ruse, Katherine complies and screams in agony until Klaus, satisfied that she has been successfully compelled, permits her to save herself. He then says she needs to do something for him. When the full moon begins to emerge, Stefan and Elena arrive home but are confronted by Klaus, who tells Stefan that he had him all nervous and thought he might have done something stupid. Klaus asks if Elena is ready. Stefan put his arm in front of Elena and says "No". Klaus tells him there is no reason for him to die, and he and Elena leave for the ritual.
Klaus returns to Alaric's apartment and tells Katherine that Elena is with Greta. The door flings open and Damon tells Klaus to postpone the ritual, explaining that he rescued the werewolf and vampire and killed Maddox. Klaus tells him that he knew either Damon or Stefan would try to stop him and reveals that he always has a back-up plan. He shows Damon on a webcam that he has captured Jules. Damon asks if he has a back-up vampire and Klaus says he has got it covered, before darkness falls on Damon. Katherine wakes Damon up and tells him that Klaus has gone to begin the ritual. She admits that she had to do something so Klaus wouldn't realize she was on vervain, and reveals that Klaus made her call Jenna, pretending to be Elena, in order to lure her out of the house so Klaus could use her as the vampire sacrifice. Katherine explains that Klaus needed another vampire because Damon's blood was made impure by his werewolf bite.
Klaus appears at the quarry and begins the sacrifice by handing the moonstone over to Greta. Klaus walks over to Jules, who then tries to attack him but fails. Klaus rips out her heart then squeezes the blood into the spell. The sacrifice continues and Elena begs Klaus to let Jenna go, explaining that she doesn't have to die. Elena doesn't want to leave Jeremy without a family and points out that she did everything Klaus asked. However, Klaus realizes that Stefan has arrived and goes to speak to him on top of a cliff. Stefan tries to negotiate himself in exchange for Jenna's life.
Klaus and Stefan return to the women and Klaus asks Elena who she wants to save and who she wants to die. However, he soon reveals that she doesn't really have a choice and stakes Stefan in the back. He explains that he has other plans for Stefan and needs him alive. Greta removes the fire circle surrounding Jenna, who rushes over to attack Greta as a last-ditch attempt to thwart her. However, Klaus stabs Jenna, lies her down, and stakes her in the heart.
Klaus appears and tells Elena it's time, offering her his hand. She refuses it and walks past him to the sacrificial altar. Klaus thanks her, but she tells him to go to hell. He bites her neck and feeds from her until she falls onto the ground, lifeless. Klaus announces that he can "feel it happening" and begins to transform. Bonnie appears and throws him across the ground. Greta heads towards them, but Damon snaps her neck.
Bonnie continues to cast the spell with Klaus yelling to the top of his lungs in pain. As he is about to die, Elijah approaches him at which point Bonnie stops the spell. Klaus seems terrified as he sees his brother towering over him. Elijah punches through Klaus' rib cage to get to his heart, and Elijah says that this was for their family. Klaus then tells him that he didn't bury them at sea and that their bodies were safe and that Elijah would never find them without him. After some consideration, Elijah saves his brother without Stefan or Bonnie being able to stop him.
A few days later wakes he up in the forest with Elijah over him. Elijah gave him some clothes and asked him where the bodies of their family were. Klaus says that he will take him to them in time. Later they go to Alaric's apartment where they find Katherine and Stefan. Stefan tells Klaus that he needs his help for Damon, and knows Klaus has a cure for Damon's werewolf bite. Klaus suddenly daggers Elijah with the White Oak Ash Dagger seemingly for trying to kill him during the sacrifice, and then he runs towards Stefan and puts a wooden stake close to his heart. Stefan then tries to make a deal with him. Klaus will give him a cure for a werewolf bite and he will be at his mercy. He releases
Stefan, and then he bites Katherine and gives her his blood and tells Stefan that his blood is the cure. In exchange for the werewolf bite cure, he forces Stefan to drink human blood several times to awaken Stefan's ripper persona. In the end he tells Katherine to go and give Damon his blood. Later he and Stefan go to a warehouse where he puts Elijah's body in a coffin and tells some men to put him with the others. Klaus then tells Stefan he has a gift for him, and beckons to a human girl. He says he wants to be sure Stefan will honor their deal, and feeds on the girl. Klaus releases her, but as she begins to flee Stefan attacks and feeds on her until she dies. Satisfied, Klaus says now they can go.
Klaus and Stefan have spent the summer tracking a werewolf named Ray Sutton down the entire Eastern seaboard, leaving a trail of bodies behind them. They ultimately find Ray in Tennessee where Klaus has Stefan kill two more girls before they corner Ray in a bar. There, Klaus tells Ray that he is a hybrid and that he wants to create more.
He has Stefan torture Ray using darts tipped in wolfsbane to force Ray to reveal the location of his pack. At this time, Klaus' is warned that Damon Salvatore had gone to the house where they had killed two women. He decides to go and put Damon in his place but Stefan insists that he should go instead. Klaus lets him. He ends up getting the location of the pack from Ray, then he finds the location of Ray's pack and ends up feeding Sutton his blood before killing him in order to turn him into a hybrid.
In The Hybrid, Klaus and Stefan find Ray's werewolf pack in the woods. Klaus feeds each of them his blood and kills them, believing this will turn them into hybrids. When Ray bleeds from his eyes and continues to feel immense pain, Klaus suspects that something has gone wrong. Ray soon becomes rabid and flees the site. Stefan, on Klaus' orders, pursues Ray to stop him and ends up bitten. Klaus says he will cure the fatal bite if Stefan retrieves Ray. The other werewolves experience the same bleeding as Ray, and Klaus kills some of them while others simply bleed to death. When Stefan comes back with Ray's dead body, Klaus is angry that he seems unable to successfully create a hybrid. Klaus gives Stefan his blood to cure the bite and they leave the campsite littered with the bodies of the failed hybrids.
In The End of the Affair, Klaus and Stefan have arrived in Chicago, where Klaus plans to meet his "favorite witch", Gloria, to find out why he can't make any new hybrids. Stefan finds an old picture of them together at the bar, and Klaus reveals that they had met before, that they had been friends back in the 1920s and that Klaus was Stefan's "number one fan", as he liked Stefan's ways of torturing others before killing them. Klaus had erased Stefan's memories of him and his sister Rebekah to protect themselves, as they were on the run from a yet unknown person. Gloria tells them that she needs Rebekah, as she has something Gloria needs. Klaus resurrects his sister, but she does not have her necklace, which they need in order to contact the Original Witch.
In Disturbing Behavior, Klaus is still using Gloria to try and find the necklace. Klaus later finds out that Stefan was asking about Mikael, the person that he was maybe running from in the 1920s. Klaus seems angered by this and knocks Stefan out then takes him back to Mystic falls to find out why he is still holding on to his former life.
At the beginning of The Reckoning, Klaus corners Elena, asking her why she is still alive. He takes her by the arm and leads her to the gym, chasing away the other students by telling them they've been busted for pranking. Elena tells Klaus not to hurt anyone, but he argues that he has to. Rebekah drags Tyler's body into the gym, and they wait till Bonnie arrives, where Klaus tells her she has to find a way that he can successfully create hybrids.
Stefan later comes in and pledges allegiance to Klaus, but both knew it was a lie as soon as Klaus hurt Elena, and Stefan tried to stop him. Klaus then compels Stefan not to fight him and to listen to him. He orders him to kill the two teenagers, Dana and Chad, whom Klaus had compelled to stay there. To make a game of everything, Klaus sets the gym clock as a countdown: Bonnie has to find a way for him to create hybrids, or else Stefan must kill Elena when time is up.
After Stefan tries to fight the compulsion, Klaus yet again compels him, this time much more emphatically, to turn his humanity off, and finally succeeds. Having overheard Matt tell Bonnie that the witches on the Other Side said the doppelgänger must be killed in order for the hybrids to survive, Klaus surmises that the opposite must be true - that the doppelgänger's blood is necessary to complete the process. He turns out to be right after he feeds Tyler a vial of Elena's blood and Tyler completes the transformation - the first hybrid after Klaus.
Damon arrives to rescue Elena at the hospital, where Klaus has hooked her up to a blood bag to extract her valuable blood. Klaus stops him in the parking lot, saying although he had promised Stefan he wouldn't kill him, now Stefan probably wouldn't care. Damon tells him that Mikael knows where they are. Klaus replies that he's bluffing, but Damon informs him that they found Mikael's tomb. Klaus throws Damon against a car and vanishes without a trace. He leaves town in search of werewolves he can turn into hybrids, and manages to find several, successfully turning them.
In Homecoming, Klaus receives a call from Stefan who tells him that Mikael is dead. Thanks to the fact that Elena really did stab Mikael with a white oak dagger, Stefan is able to override Klaus' compulsion when he is forced to tell the truth. Rebekah, who has learned that Klaus had killed their mother, corroborates Stefan's lie in an attempt to lure him back to Mystic Falls. Klaus says that he will be on his way. In the meantime, he gives Tyler orders to throw a party to celebrate Mikael's death.
After seeing who he thinks is Elena, he reveals that his hybrids are present throughout the crowd, and they have orders to kill Damon if Klaus is killed. The party goes well, until one of his hybrids says that a guest named Mikael is waiting for him. Visibly angered, he goes to meet his step-father at the door. Klaus attempts to have his hybrids attack Mikael, but Mikael reveals that while they are sired to Klaus, they are part vampire and can therefore be compelled by Mikael, an Original. Mikael reveals that he had one of the hybrids grab 'Elena' and threatens to kill her if Klaus doesn't come outside of the Lockwood house.
Klaus tries to call Mikael's bluff, but Mikael stabs her. To everyone's shock, it isn't Elena at all, but Katherine, who throws wolfsbane grenades at the hybrids and runs. Damon then appears and attacks Klaus with the white oak stake. However, Stefan interrupts the battle, pulling Damon off of Klaus. Klaus grabs the stake and drives it through Mikael's heart, killing him and destroying the stake in the process.
When Damon asks Stefan what he was doing, it is Klaus who answers by saying that Stefan was earning his freedom, which Klaus then grants him before leaving again. Unaware of his sister's role in the murder attempt, he calls to tell her that Mikael is dead and that it is time to go, but he is unable to reach her (Elena had daggered her before the homecoming dance). Stefan then calls and reveals that he had stolen the coffins containing Klaus' siblings, whom Klaus intended to revive now that Mikael was dead. Klaus threatens to kill Stefan and anyone Stefan ever met, but Stefan merely replies that if he does, he will never see his family again.
In The New Deal, Klaus is having a house renovated for himself and his hybrids to live in while in Mystic Falls. He meets Damon and Elena at the Grill asking where Stefan is. When they don't cooperate, he leaves, hinting that Stefan's whereabouts might soon be their problem as well as his. Later, while discussing his predicament with Damon, Klaus calls Jeremy and tells him to do "that thing" he'd told him to - clearly Klaus had compelled him earlier that day to wait for and obey his instructions to go outside into the street and not to move. Klaus' hybrid attempts to kill Jeremy by hitting him with a car, but Alaric saves him. Once back at his house, Klaus chats with Tyler about the day's events, mentioning that humans are a means to an end. Later he arrives at the Salvatore Boarding House to meet Elena, who leads him to the cellar where Rebekah lies daggered. Elena uses Rebekah as a bargaining chip in exchange for sparing Jeremy, but Klaus reminds her that he has plenty of ways to get what he wants, including hurting other people she loves. Before she leaves the cellar, Elena reveals that she told Rebekah about how Klaus was the one who killed their mother, not Mikael. Having returned to his mansion with Rebekah, he re-daggers her before she can revive, and returns her to her coffin rather than face her wrath for his betrayal.
In Our Town, Stefan visits Klaus and tells him to get his hybrids out of the town. When he doesn't agree, Stefan kills Mindy by decapitating her. Klaus is angry and tells Tyler to bite Caroline but he refuses. Later, Klaus attends the Founder's Council Feast and persuades the Mayor that his hybrids would protect the town. Damon tries to call Elena and Stefan answers; worried about what Elena has to do with Stefan's plans, he tries to convince Klaus Stefan means business. Stefan calls Klaus and threatens to take away his "blood source" by driving Elena off of Wickery Bridge. To prove his point, Stefan forces Elena to drink his blood. Hearing this and Elena pleading with Stefan to slow down, Klaus finally promises to get his hybrids out of Mystic Falls.
After Tyler unwillingly follows Klaus' orders and bites Caroline, he goes to Klaus asking him for help. Klaus goes to the Forbes house to heal Caroline. Liz invites him in and he has a intimate conversation with Caroline about being immortal. Eventually, he feeds Caroline his bloods and says "Happy Birthday". After Caroline wakes up the next morning, Klaus has left but she finds an expensive bracelet made of dozens of diamonds: a gift from Klaus.
In The Ties That Bind, Klaus appears in one of Bonnie's dreams as she tries to open the locked coffin. Back in present time Stefan comes home and finds Klaus there, "enjoying" their stalemate. Klaus repeats his demand that Stefan return his family, now that his hybrids left town. It is revealed that he ordered Daniel Warren, a hybrid, to go to the house of Abby Bennett and handle the situation, which he does by manipulating Abby and her foster son Jamie in order to get Bonnie to reveal the location of the coffins.
Later, after Bonnie finally divulges the location, Klaus arrives at the Abandoned Cottage to find Damon there. After insulting them, the witch spirits torture Klaus until he pushes back by threatening to end the Bennett line. He then commands them to show him the coffins and they do - except the fourth one is missing. He asks Damon where the last one is and he threatens to rip out his heart, but Damon reminds him that the fourth coffin is leverage and Klaus wouldn't kill the person that knows where it is. After the other coffins were moved to his house, Klaus is surprised by Elijah, un-daggered earlier by Damon, standing in front of him after killing a hybrid.
In Bringing Out The Dead, Elijah attacks Klaus for having daggered him but Klaus overpowers him and, having pulled the dagger out of their brother Kol, threatens to use it on him. Elijah retorts that he would have to deal with Kol then. Klaus resigns himself to that fact and tells Elijah that Mikael was dead. Surprised to hear of their father's death, Elijah asks why their family remains in the coffins. Klaus asks Elijah to help him get the fourth coffin back from Stefan by reminding him of the oath that they had sworn to one another: 'always and forever'. Elijah then organizes a dinner, inviting Stefan and Damon. The brothers offer the deal that, in exchange for the coffin, Klaus will leave Mystic Falls forever, a deal that Elijah deems to be fair.
Klaus later counters with his own offer: Elena's future happiness with a human husband, in exchange for the coffin; this would keep her safe from what he deemed to be a dangerous feud between the Salvatore brothers, and would ensure the continuity of the Petrova bloodline so that he could keep creating hybrids. Stefan refuses the deal. Klaus then grabs him and burns his hand in the flames while Elijah prevents Damon from intervening. Klaus tells Damon to bring him the coffin or he will kill Stefan. Damon complies and Klaus sends Elijah with him. However, Elijah and Damon return soon afterwards, not with the coffin but with the daggers that Elijah had removed from the other Original siblings.
Elijah claims to have learned not to trust Klaus' promises and declares that this will be done on his terms. Kol then appears, followed by Finn, who stabs Klaus in the hand after he tries to seize the dagger. As Klaus tries to run, Rebekah appears and stabs him, saying "This is for our mother". Klaus stumbles back and is caught by Kol. Elijah dismisses Damon and Stefan. Rebekah announces that they are all leaving him. Suddenly Esther walks in the door and tells her children to stop fighting. She tells Klaus to look at her and asks if he knows why she is there. When Klaus suggests that she is probably there to kill him, she says she is there to forgive him, and that she wants them all to be a family again.
InDangerous Liaisons, Esther organizes a ball to celebrate the reunion of their family and asks Klaus who he is going to bring to the event. Klaus decides to send a ball dress as a present to Caroline, along with the invitation and a note to save him a dance. She arrives that evening wearing the dress and the bracelet he had given her for her birthday. She dances the waltz with him while he asks her how she's been doing since her father died, tells her how beautiful she looks in the dress he gave her, and compliments her dancing skills.
Klaus later approaches Caroline outside, where she is admiring a horse. Klaus confides that the closest Mikael ever got to killing him was the time he killed Klaus' favorite horse as a warning. Caroline asks whether he had ever thought to talk it out with his father, but Klaus insists his relationship with his father was far more complex than her relationship with hers. She allows this, but changes the subject as an excuse to go inside. Later, Klaus shows Caroline his private art collection. He tells her about his own work and asks if she has been to the Hermitage. When she admits she hasn't really been anywhere like that, he promises to take her anywhere she wants. Caroline chastises Klaus for his extravagance, positing that he wants to create hybrids to be his servants. He deflects her demand that he set Tyler free. She then blames his obsession with creating hybrids and giving expensive gifts on what she thinks is his belief that no one could love him otherwise. Angered, she leaves him alone in the room. At home, Caroline finds a drawing of her with a horse, as well as a note from Klaus thanking her for her honesty.
In All My Children, Klaus is with Kol in the house. Rebekah comes home from her one night stand while Klaus sits sketching. Kol says he's bored so he and Klaus leave the room. They head to the Grill where they meet Alaric and Meredith Fell. As a distraction, planned by Damon, Caroline enters the pub but seems displeased to see Klaus and immediately leaves. He follows her outside and dares her to get to know him. They sit together on a bench and talk. Later, after Kol gets neutralized, Klaus feels something in his chest and recognizes something must have happened.
He rushes to find Kol, pulls the dagger out and threatens to kill the Salvatores, but Elijah stops him. Together with Kol and Elijah he goes to the Witch Burial Ground, where Esther is performing a spell to kill her children. Klaus orders her to end this or he'll send her back to hell. She responds that she has hated to see how they all shed blood throughout the centuries. After the spell is interrupted thanks to the Salvatores, Esther disappears with Finn. Later, Klaus is burning the pictures he had drawn of Caroline when Rebekah joins him. She says she had hated him when she found out that he killed their mother, but Klaus is the only one who has never left her. She then delivers the shocking news that a sapling of a white oak tree had been planted 300 years after they left the Old World.
In The Murder of One, Klaus and Rebekah join forces to get Finn on their side by reuniting him with Sage. He then gets Bonnie to undo Esther's linking spell. He first tries to bribe Bonnie by offering to reunite her with her mother, but when Bonnie refuses, he instead threatens to kill Jeremy. Klaus watches as Rebekah tortures Damon, but they stop when Stefan comes by and offers to trade his white oak stakes for Damon's freedom. Klaus then learns that there are more white oak stakes and that one of them was used to kill Finn.
In Heart of Darkness, Klaus wants to get the last remaining white oak stake, and sends Kol to stop Damon and Elena from learning of their bloodline origin. He gets impatient waiting for Alaric's alter-ego to fess up and eventually kills him to speed up the process. Later, once Alaric had divulged its location to Stefan, Klaus sends Rebekah with Alaric to retrieve it, not knowing that Rebekah is possessed by Esther.
In Do Not Go Gentle, Esther, while possessing Rebekah, convinces Klaus to go the 1920s dance by telling him that Caroline will be there. At the dance Klaus sees Caroline and Tyler dancing and he interrupts them by asking Tyler where he's been. He then asks Caroline to dance; at first she refuses him, but then Tyler says it's all right. While dancing, Klaus tells her how she would have loved the 1920s and that he will be leaving Mystic Falls that night. After Klaus tries calling Rebekah, Stefan informs him that Esther is back.
After Esther is killed, Klaus states angrily that Esther will never be able to stop him and that he will continue to live.
In Before Sunset, Klaus is informed by Rebekah that Alaric survived, and that the white oak stake has no effect on him. Rebekah wishes to leave, but Klaus states that he will not leave without Elena, causing Rebekah to get angry and state that she won't care even if he does die, before leaving. Klaus then goes to Elena's house to collect her, however Stefan and Damon bar his way. He begins attacking the house from the outside, trying to force them to invite him in, but they manage to repel him. Just as he is about to cause the place to explode, Stefan comes out and says that Alaric has captured both Elena and Caroline and will only give them up if Klaus hands himself over. Klaus initially refuse, but Bonnie comes up with a plan that will allow them to actually succeed. He then agrees, but makes it clear that after this he is taking Elena and leaving. He waits in front of the school-where Alaric has Caroline and Elena-with Stefan and the two talk, Klaus trying to drive a wedge between the brothers again.
When Stefan states that all of Klaus' attempts to break the Salvatore brothers apart has only made their bond stronger, Klaus counters by asking what will happen when Elena finally chooses between them. Then, Bonnie, Damon and Jeremy show up. Bonnie gives the vampires a vial of her blood, saying that once they drink it, all they have to do is make a connection with Alaric's heart, and she will use her magic to stop it, effectively neutralized him. After drinking the blood, Klaus enters the school with the Salvatores.
He comes across Caroline and grabs her, keeping her quiet and telling her that she will be fine, and that she must get home as soon as possible, she thanks him then runs. Stefan and Damon restrain Alaric, and Klaus plunges his fingers into his heart, but Alaric manages to get free, break Stefan and Damon's necks and nearly drove his white oak stake through Klaus' heart. Ironically, Elena saved Klaus by threatening to kill herself, deducing that Esther bound Alaric's life to hers so that he could only live one life time. As she prepared to follow through with her threat Alaric went to stop her, freeing Klaus, who then ran off with her.
He then began draining Elena of all her blood, that way gaining enough blood to at least have some hybrids, while also killing off the greatest threat to him. When Elena asks why he is killing her, as he won't have an unlimited army anymore, he states that he doesn't need one as he has his family back. Elena counters saying that they will never truly trust him again, and that he is wants a back up family, which is why he is draining her blood instead of simply snapping her neck. Later, Tyler shows up and tries to free her, but Klaus finds him before he can get Elena out of the house.
He asks how Tyler broke the sire bond, and Klaus states that that is impossible, Tyler countering by saying that true love is more important than sire bond induced loyalty. Klaus states that Tyler should be thanking him as he saved Tyler from the misery of life as a werewolf, but Tyler says that Klaus doesn't give a crap about him, he only wanted to not be alone. Klaus then prepares to kill him, but Stefan and Damon arrive. Tyler and Damon restrain Klaus, while Stefan plunges his hand into Klaus' chest, and Bonnie begins her spell again. Klaus looks at Stefan with a mixture of sadness and shock as his life fades away. He is then completely desiccated , and his dead body falls to the floor. Everyone then holds a victory party, and Stefan and Damon later drive off with the purpose of disposing of Klaus' corpse.
In The Departed, Damon stores Klaus' coffin in a warehouse outside of Mystic Falls. Bonnie arrives at the warehouse, and Damon tells her that he hid Klaus' coffin in compartment 1020, saying that compartment 666 would be too obvious (666 is the Devil's number, with Damon indicating that Klaus is the Devil). Bonnie and Damon enter the compartment, and open Klaus' coffin. Klaus wakes up from his sleep, but is still in a desiccated state. Bonnie then asks Damon to give her a moment alone with Klaus, saying that she wants to appreciate the sight of him like this. After Damon leaves, Bonnie tells him that he should burn in hell.
However, she knows that if he dies, so does her mother and friends, and she questions him what she is supposed to do about that. Off-screen, Bonnie saves Klaus from Alaric by performing a spell that transferred his spirit into Tyler Lockwood's body and possibly preserve his physical form. Later, Alaric shows up at the warehouse, catching Damon off guard. He demands to know Klaus' location, and Damon tells him that he stored in one of the compartments. Rebekah later shows up to retrieve Klaus' coffin. Rebekah and Damon try to sneak Klaus out of the warehouse, but are caught by Alaric. Alaric slams Rebekah against the car and tosses her aside. Damon tries to stop Alaric from opening Klaus' coffin, but fails. Alaric does so, and brandishing the White Oak Stake, plunges the weapon into Klaus' heart. Klaus gasps in pain and bursts into flames, Rebekah screaming in horror. Damon gives Rebekah time to escape Alaric.
Afterward you see Bonnie talking to Tyler and realize she put a spell on him to transition his "soul" in with Tyler. He tells her that she did the spell brilliantly and he didn't think she had it in her as she tells him she did it to protect her friends and her mother.
In the season premiere, Growing Pains, Klaus, still in Tyler's body, is still in hiding. Bonnie tells him that their agreement was for him to jump into another body, however Klaus learning that his body is still intact, he wants her to put him back in his body. Bonnie tells him she can't right away as she has to use her magic to attempt to bring Elena back to life. Klaus informs her that Elena is no longer his concern, but is convinced to let Bonnie try to save Elena in order to keep the Petrova Doppelgänger bloodline alive. While waiting, Mrs. Lockwood calls on Tyler's phone and informs Klaus of Caroline being taken. He rescues Caroline, but leaves Rebekah, to "keep them busy" calling her little sister, revealing that he is really Klaus.
After escaping Caroline is happy to see that Tyler is still alive and the two begin making out, however Klaus calls her "love" which leads Caroline to realize that it is really Klaus. They find Bonnie to complete the spell and while she originally refuses to use the dark magic needed, Klaus begins ripping Tyler's heart out, forcing Bonnie to do the spell.
Later that night, now back in his body, he returns to his home to get the last of Elena's blood, when Rebekah arrives upset that he saved Caroline, but not her. Rebekah upset over his betrayal and her realization that he will always choose his hybrids over her, destroys the blood bags. He grabs her and tells her that they are no longer family, he snaps her neck and leaves her on the floor unconscious.
In The Rager, Carol Lockwood calls Klaus and his last remaining hybrids back to Mystic Falls to serve as protection for Tyler. Although Klaus no longer cares, he isn't willing to let one of the few hybrids he has left die. He later meets Hayley, a werewolf who helped Tyler overcome his sire-bond, and discovers that Tyler has been keeping things from Caroline, thinking Tyler had an affair with Hayley while she helped him break the sire-bond. He joins Damon in the trapping and interrogation of Connor Jordan, where he discovers that Connor is part of a mysterious group of vampire hunters known as the Five. He then saves Connor from the explosion and also saves Elena from the werewolf venom she had drunk, claiming that she could be of some use to him after all.
In The Five, Klaus is first seen in the Mystic Grill when Rebekah was flirting on Matt and he told her she was trying to hard. He tried to get her to work with him after he told her that the Brotherhood of the Five still existed, but she was still mad at him for what had happened. He was later seen talking to Connor, who was tied up in his mansion, asking him for information. When Stefan entered, Klaus started telling him about the past. He remembers he was in Italy talking to his brother Elijah, when Alexander, one of the Five, showed in front of everyone a vampire, killing him by exposing him to sunlight, but Klaus didn't feel threatened by him. He later convinced Stefan to get Rebekah to his mansion, which he did. The three of them were having dinner when Klaus and Rebekah continue telling Stefan of when Alexander and the other members of the Five, who originally owned the White Oak Ash Daggers, daggered all of the siblings, but due to Klaus' werewolf side, it didn't work on him.
He killed all of the Five and undaggered his siblings, except for Finn. They told Stefan about the existence of The Cure, and Klaus said that the Hunter's Mark tattoo on Connor was going to lead them to it. He brought in Jeremy and ordered him to draw Connor's tattoo since he was the only one who saw it. Then Rebekah got angry after Klaus tells her he still didn't trust her and left. When Klaus later sees Jeremy drawing of the tattoo, he gets angry because Jeremy didn't do all of it, but he tells him that it grew each time he killed a vampire, and it wasn't complete yet. He then calls in Nate, one of his hybrids, and tells him to tell the girl to take Jeremy home and told Nate to make sure Connor stayed there and alive. Finally, he was seen again when Rebekah went to the Salvatore Boarding House to talk to Stefan, and he calls Rebekah a hopeless fool for loving too much, and daggers her.
In The Killer, Klaus was in Italy digging up Alexander's sword. He was first seen when Stefan was talking to him on the phone, telling him that Connor had escaped. He pointed out that Connor had werewolf venom, and since he was halfway around the world, he couldn't cure anyone since they had no access to his blood. He orders Stefan to make sure that Connor is kept alive at all cost, and also warned him to not tell Damon about The Cure.
He was later seen again when they had managed to find the sword. Tyler calls him and tells him that sending Dean to confront Connor was a suicide mission and that he should stop him, but Klaus threatened to tell Caroline about what he thought that Tyler had done with Hayley, so Tyler hung up and told Dean he could do it.
In We All Go a Little Mad Sometimes, Klaus was seen at the Lockwood Mansion along with his Hybrids, drinking in honor of Dean’s death. Then after Caroline came to return all of Tyler's things and broke up with Tyler in front of him, he left the place with his hybrids to give them time alone. But as soon he left, it was revealed that Caroline, Hayley and Tyler faked it. Meanwhile, Klaus called Stefan and taunted him about ruining his plans for a hybrid filled future and asked him how Elena was doing with her hallucinations. Stefan asked him how he knew about that, and Klaus reminded Stefan that he had killed the original members of The Five, so he knew about it. Then he asked Stefan where he was. Stefan said he was at Elena's place. Klaus also came there and Stefan came out to talk to him. Klaus suggested for Stefan to hand over Elena, or else she'll kill herself before the end of the day. Meanwhile, Elena was hallucinating again and fled from the house, and Klaus took that opportunity to carry her away. Then Klaus put Elena in a windowless room. He said it was for her protection else she would take off her daylight ring and burn herself to death.
When Elena said she would never do that Klaus told her she would want to kill herself as he had once and he had to bear the torture for nearly 52 years. But when she asked him how he stopped it and he said it stopped on it's own.
Later, according to Stefan’s plan to rescue Elena from Klaus, Caroline came to distract Klaus when he was drinking at the Mystic Grill. Klaus offered Caroline a drink and asked her about the break up, but she brushed him off saying that wasn't his business. Then Klaus said that he would never allow Tyler to hurt her if Tyler was sired to him. Stefan texted everything to Caroline after losing Elena again. Caroline then confessed to Klaus what she was really doing and told him that they figured out a way to end the Hunter's Curse. Then Klaus arrived at the Lockwood Mansion when Chris was about to leave. He let Jeremy kill Chris, and the Hunter's Curse was broken. Later it was revealed that Klaus gave up one hybrid, (Chris), after Caroline agreed to go on a date with him.
In My Brother’s Keeper, Klaus was first seen when Stefan was in the woods alone and Klaus came up behind him and threatened him for telling Damon about the Cure. He ordered him to help Jeremy complete his Hunter's Mark, or he would give him up as a victim himself to Jeremy. He was later seen when Caroline was organizing the Miss Mystic Falls Ceremony and he asked her at what time he should pick her up for their date to following day. When she refused the date, he reminded her that he was promised a date in return of one of his hybrids, so she had to agree. He was later seen at the pageant when Caroline was complaining about how the ceremony was going when he came up to her and asked how he was, and she said perfect, despite him being so annoying that she can't even look at him. He pointed out that Tyler and Hayley where there together, leaving her confused.
He was later seen when Caroline and Elena were arguing and he came to stop Caroline because she was making a scene, and he told her to go with him to have some champagne. They were on a bench together and they were talking about being human, and when Caroline asked Klaus if he wanted to be human, he asked why he would rather be human instead of being one of the most powerful creatures on earth. Then, he started joking with Caroline, reading out her previous Miss Mystic Falls application, and she was trying to stop him. They were laughing together. Later, he came up to Caroline and told her that he once wanted to be a human. He had seen a hummingbird, with it's heart pattering like a machine gun, and he realised how beautiful it was to work hard every day to survive and the feeling of satisfaction every day for surviving.
In O Come, All Ye Faithful, Klaus was first seen in his mansion drawing a painting of a giant snowflake to donate for the Winter Wonderland charity event and later told Adrian to take it to the Mystic Grill. Stefan came up to him and asked him about when they were going to find the cure, and he told him that he had done his part by finding the sword, now Stefan had to do his part by helping Jeremy complete his mark. Stefan told him that he didn't trust him about finding his sword, so Klaus showed it to him from the safe. He was later seen in the Mystic Grill when Caroline was looking at his painting and he came up to her to talk to her. He said she liked his painting, and he then offered to have some champagne together. At first she refused, but then she agreed, and asked her if that was their thing (having champagne together) and she replied they didn't have thing. It was shown that Tyler was planning to put Klaus in his body and then they would him in concrete. Hayley said that she had found the witch to perform to spell. They wanted to get rid of Klaus. Later, the plan had changed to put Klaus in Rebekah's daggered body. Klaus was later seen at night at the party when Stefan came up to him. He told him that he had broken in his mansion to find the sword, which he didn't, but instead he found his victims' letters, which he replied that it was his way of keeping a reminder that in the end we’re left infinitely and utterly alone, which was like his way of writing his victims' names on the wall. Klaus saw Adrian and left with him.
He was later seen when Kimberley and the other hybrids were waiting for the witch, and Klaus showed up with Adrian and pulled his heart out. He started killing all the hybrids with the hunter's sword, and the last one left was Kimberley. She tried to run away in the Lockwood Cellar, but he followed her and asked her if she knew where Tyler was. She said that she didn't, and so he killed her by decapitation. It was revealed that Hayley didn't really have a witch, and she wanted Klaus the kill the 12 hybrids for the sacrifice.
At the last scene of the episode, Carol was the last one left at the party and was waiting for Tyler to pick her up. She sat down on the fountain, and Klaus came up to her, telling her that he was also looking for Tyler to have a word with him. Carol begged him not to hurt Tyler since he was her son and the only thing she had. He told her that she was also all that he had, and it was a beautiful symmetry. So, he grabbed her and drowned her in the fountain, killing her.
In After School Special, Klaus visited the lake house to check up on Jeremy's progress in growing his mark only to find that he hadn't killed any vampires since he was too busy being trained by Damon. Klaus chastised Damon for this, saying that there was a whole town of people he could turn into vampires that Jeremy could kill but Damon wanted to make sure Jeremy was all trained up before he began. Klaus managed to convince Damon that his way would be the most efficient and then proceeded to turn all of the townspeople, enjoying a quiet drink while the entire town was starting to transition.
In Catch Me If You Can, we returned to the bar where Klaus had massacred those innocents so Jeremy could kill them all after they'd transitioned and grow his mark.. Elenawent to see Klaus to beg him to call off Kol. She convinced him that they were all on the same team to a point -- Team Cure Should Be Found. They only differed on how to use it. So Klaus called Kol and told him to stay away from Jeremy, and if causes any more trouble, he'd end up back in a box. Kol agreed that he wouldn't touch Jeremy but compelled Damon to kill Jeremy. Later, Klaus saved Rebekah from Kol almost killing her. Which shows that he still cares about his little sister. We also had to see Klaus come to Elena's to demand he house Jeremy now that Kol will undoubtedly come after him again. Elena and Jeremy opted for Jeremy to stay at their house, where at least Kol couldn't get in but he noted that his brother could burn it down. Klaus told Elena to tell when Kol returns, and he told Jeremy there was no shortage of people to turn or loved ones to threaten, so they'd finish their work on the mark the next day.
In A View To A Kill, Klaus comes to Rebekah's house to momentarily unite their teams against Kol, who now has the white oak stake as well as Klaus’ set of daggers. Klaus knew Rebekah has the last dagger and some white ash, and he wanted it so he could put Kol back in a box. Rebekah didn’t want to leave herself unprotected, so she told Klaus to get gone. Klaus asked Stefan to talk some sense into her: If they dagger Kol, Damon will no longer be compelled to kill Jeremy, and the hunt for the cure could continue.
Stefan apparently agreed to the Original's proposal, but only on the condition that he takes Stefan's place as Damon's "babysitter" at the Salvatore House while Stefan tries to persuade Rebekah. He is later seen with Stefan visiting Damon at his confinement.
Stefan told Klaus to give Damon a vial of blood every couple of hours so he doesn’t desiccate. He gave him permission to bleed him out again, if needed. Damon told Klaus that Stefan was still mad at him for sleeping with Elena, and Klaus told Damon about catching Stefan sneaking out of Rebekah’s bed. Klaus was inside the cellar with Damon villain-bonding. Klaus asked Damon how he gets Elena to overlook every horrible thing he’s done: “What is it you say to her?”Damon knew what this was about: Klaus is afraid Caroline won’t forgive him for killing Carol Lockwood. Damon gave him a real answer: Damon is the bad guy to things get done, Klaus is a bad guy just to be a dick. “If you’re gonna be bad, be bad with purpose; otherwise, you’re just not worth forgiving.”
Damon and Klaus, the latter of whom was infuriated by Stefan’s lack of communication. “It’s one of his trademarks, like his brooding and his hair,” Damon said. Klaus entertained himself trying to wind Damon up. He pointed out how Stefan had fought so hard to fight Klaus' compulsion to feed on Elena that he was able to momentarily beat it. Whereas Damon couldn’t resist Kol’s to kill Jeremy. Damon may love Elena, Klaus said, but will Elena see that Stefan is the greater love when they find the cure? Klaus thinks that’s what’ll happen, and he believes Damon does, too. Kol called Klaus at that moment. He assumed that Klaus was in on this plan to kill him. Klaus, meanwhile, freaked out and asked Damon what Stefan and Elena were planning. Damon genuinely didn’t know. Klaus thought he’d compelled Damon to stay in the cellar, but Damon had been drinking that bottled water Stefan gave him, which had vervain in it.
When Jeremy staked Kol, Klaus had shown up, just in time to see Kol ablaze. He had tears and anger in his eyes. Elena tried to play it off like they had no choice, but Klaus knew they’d set a trap for Kol if he was even inside the house. He said he was going to set the house on fire and kill them when they fled. Jeremy said Klaus would never get the cure then for Elena to make more hybrids. Klaus let something slip: He didn’t want the cure so he could make hybrids. He wanted it so he could destroy it. He was going to kill them all as soon as he found it. Before he could make good on his arson threat, Bonnie showed up. She crippled him, then told Jeremy to invite him in. She put up magical barriers to keep Klaus trapped there.
In Into the Wild, Klaus was still trapped in the Gilbert house, forced to stare at his little brother's charred body. Tyler showed up, still furious with Klaus for killing his mother. He was gloating, telling Klaus that the others would find the cure and when they did, Tyler was going to shove it down Klaus' throat and kill him in whatever way he pleased. Klaus told him that he couldn't be sure that he wouldn't die too, since he was part of his bloodline but Tyler seemed certain that once Klaus was human again, all the vampires in his bloodline would no longer be connected to him. Caroline arrived and after chastising Tyler for baiting Klaus, covered Kol's body with a tarp, relieving Klaus of having to look at his brother's body. When Caroline showed Klaus that she had now given up on him, not feeling sorry at all for him, Klaus struck quickly, pulling her up to him before biting her. His hybrid bite was fatal too her so she hastily began developing symptoms and slowly dying. Klaus told Tyler that he wanted an apology for turning his hybrids and on him and after some deliberation, Tyler did so but Klaus still didn't heal Caroline. It was only after she told him that she knew there was still a bit of humanity in him that Klaus reconsidered and healed Caroline.
In Down the Rabbit Hole, Klaus remained stuck behind Bonnie's barriers while Caroline was on the phone with Elena, trying to figure out where the sword was. Caroline and Tyler, knowing Klaus wouldn't be going anywhere, found the sword at his house and brought it back to the Gilbert's. They found secret messages beneath the hilt of the sword that Klaus decrypted in an ancient language. It revealed that there was only one dose of the cure. Knowing that with one dose, they wouldn't be using it on Klaus, Tyler decided to flee and go into hiding, knowing full well that Klaus would kill him the moment he was free. Caroline pleaded with Klaus to let Tyler go and after some persuasion, Klaus submitted but only that he'd give Tyler a headstart.
In Bring It On, Klaus saves Hayley from a vampire sent by Katherine to take her out for her part in the cure hunt. Klaus promises Hayley protection in exchange for her revealing to him all she knows about Katherine. Back in Mystic Falls, Klaus is visited by Damon who reveals that he knows about Hayley and wants to talk to her. Klaus refuses, although he does tell Damon about the vampire he attacked and that, due to the hybrid bite, does not have long to live. Klaus is later seen interrogating Hayley, after feeding her and she starts to reveal both her link to Katherine and her motivation: her desire to find her birth family led her to Katherine who promised that she could help if Hayley told her about the hunt for the cure. Klaus, enjoying the time spent with Hayley, then shows her his paintings and explains some of his motivations about art, namely his desire for control which he can channel through painting. Hayley then tries to convince Klaus to call off his hunt for Tyler, revealing that it wasn't resolve but the help of other people which would provide Tyler with his ability to escape him, just as Katherine had for five hundred years. Klaus later receives word from Rebekah that Hayley's attacker had been killed by Damon. He then tells Hayley that she can leave or stay. Hayley then reveals her liking for one of his paintings, saying that she liked it because it showed her how twisted Klaus really was, and that she could relate to it. The two then begin to make out before having sex. As Hayley is getting dressed, Klaus notices a birth mark on her right shoulder and reveals that the mark was common to all the members of a werewolf clan in Louisiana. Hayley asks him to tell her about her birth family.
In Because the Night, Klaus arrives at the Salvatore House where Caroline is cleaning up after the previous night's party. She is still sore about the events of that night, namely Elena's attack on both her and her mother. She is also angry at Klaus for refusing to call off his quest to kill Tyler and refuses to forgive him. Stefan then arrives and reveals that he believes that Silas had followed them back to Mystic Falls. Klaus, although originally not interested, is alarmed when Stefan and Caroline reveal Silas's plans to bring down the Other Side, which would bring back every single one of Klaus' dead enemies. They raid Shane's office to find information about the Expression Triangle of massacres that he is trying to perform. During the search, Klaus and Caroline continue their bickering and Klaus states his belief that every person, no matter how pure their heart is, will be drawn to the dark. Caroline then finds out that the Triangle required three distinct massacres: a human one, a demon one (hence the massacre of the hybrids), and a witch massacre. Realizing Silas's plans, they deduce the location of the final massacre at two potential location and split up to find them. Caroline accompanies Klaus and they continuously bicker, leading Klaus to ask her why she went with him instead of Stefan. She says that she doesn't want him to kill Bonnie (who is working with Silas) when they find her. However, they are not at the right spot. When they join Stefan, they discover a coven of 12 witches led by Aja trying to purge Bonnie of the Expression magic by killing her. Stefan tries to save her but Klaus won't let him because this would call for the death of the linked witches, which would perform the final massacre. However, Caroline kills Aja, and the other witches to save her friend, despite Klaus' attempts to stop her.
Klaus later buries the witches and is shown to be angry at a distraught Caroline for performing the final massacre. Caroline tries to defend her actions by saying that she couldn't let Bonnie die but then realizes what she has done. Klaus then tells her that she needs comforting but he refuses to comfort her himself because of her words to him in the day and her actions that night. After Caroline leaves, Klaus is surprised to find Silas at the site, thanking him for performing the massacre. Silas then offers Klaus a deal: they can find the cure together and Silas will take it to accomplish his goals and therefore ensure that Klaus while not be at the receiving end of the cure. Klaus then boasts that he isn't scared of Silas, despite his age. However, Silas reveals that he stole the White Oak Stake from Rebekah and that he knows it is the only thing that can kill him. Klaus tries to attack Silas but the ancient immortal is much faster than him and stakes him from behind with the stake, breaking off the tip inside him, badly injuring Klaus before leaving him in severe pain.
In American Gothic, Klaus was trying to get the piece of the white oak stake was still inside his back in a spot he could not reach. Caroline arrived. She touched his face. Instead, she said, “As much as I’d love to watch you die, you still haven’t found me that cure.” It was Silas. He can take the shape of whomever he wants you to see.
Klaus was sweaty and cowering on the floor when Caroline came in again. He started to think it was the real her when she quipped about how she should be running three prom committees at that moment. He told her about the white oak stake, and since he was hurt, she was the person to call. She found that hard to follow: He ran Tyler out-of-town and killed his mother. But, Klaus reminded her, if he dies, Caroline and everyone she knows dies. She had to help. He told her she’d need to cut the stake out of him. Caroline was having a difficult time getting the stake out of Klaus. Caroline finally smartened up: If Klaus wants her help, he’s gonna have to let Tyler come back and promise not to kill him. Klaus could feel the splinters moving toward his heart and begged Caroline to help him, but she wouldn’t until he promised not to hurt Tyler. He wouldn’t do that because Tyler tried to kill him, but yeah, Caroline’s right, Klaus has tried to kill most of them. This turned into a conversation about trust being the foundation of friendship, and Caroline angrily yelling that she should’ve turned her back on Klaus ages ago. That was a punch to the gut, but silver lining, Klaus’ pain was gone. Silas had gotten into his head and made him think he was dying. Caroline had taken Klaus’ mind off of it enough to break the spell, apparently. Seriously, if Silas can make Klaus think he’s croaking, then what can he do to the rest of them?
Caroline was ready to call it a night after using all of Klaus’ bleach to clean up. He thanked her for her help. She poked his chest when she told him if he needs anything else not to call her because she has a prom to plan. "Friends?" he asked. She asked if he was letting Tyler come back to town. He didn’t answer, at first. But he did then say she might have noticed that he’s not exactly scouring the earth for Tyler. She smiled a bit. So did he.
In Pictures of You, at Klaus' mansion, he and Rebekah tried to convince Elijah who should get the cure, and again, provide a little recap: Silas will torment Klaus until he gets it, but he'll also open the floodgates so every dead supernatural being returns to our side. Rebekah really wants to be human. Elijah, being sensible as always, told Klaus his personal discomfort wasn't enough of a reason to put the world in jeopardy. Klaus' smile turned to a frown when Elijah agreed to give Rebekah a shot at happiness, and he told Rebekah when she's dying and asking for his life-saving blood, he'll deny her and compel her to forget him.
When Caroline showed up, Klaus laughed at Caroline, obviously, but couldn't resist her when she smiled and begged him to go into his "creepy trophy chest of family collectibles" and find her a gown that would make her look "Princess Grace of Monaco" hot to which he did. Rebekah had given Elijah the white oak stake, and Elijah presented it to Klaus as a peace-offering. Now Klaus had nothing to fear -- except Silas' torment. Elijah said Klaus could outrun Silas if he had to, and that naturally made Klaus think of Katherine. Elijah asked Klaus to let him have this opportunity to feel and to love and Klaus refused. If he doesn't the get cure and ends up running, he's headed to kill her. He'll make sure Elijah is never happy.
Klaus had decided to go to the prom for some unknown reason and saw what had just happened. Rebekah argued that she'd acted with human decency and Klaus said no, the most human thing in that moment would have been if she could stomach standing by watching April die knowing she couldn't help her. Before this episode ended, he a letter from Katherine telling him about a witch in New Orleans plotting a move against him.
In The Originals, Klaus travels to New Orleans, concluding Katherine's letter about the witch planning a move against him. Once in New Orleans he finds a real witch amongst a group of fakes, he asks this witch where he can find Jane-Anne Deveraux, the witch tells Klaus she cannot tell Klaus where she is or it would be breaking one of Marcel's rules. Klaus then asks this witch were he can find Marcel.
Klaus goes to a pub to find his progeny Marcel, who is singing on stage. When Marcel has finished he goes to celebrate with his buddy's and spots Klaus in the corner of his eye. Klaus and Marcel start to argue before celebrating Klaus' return. Klaus is Marcel's sire, and Marcel has shared the secret of the daylight ring with his inner circle, who he considers family. How did he get witches to make them rings? Marcel said he has the witches wrapped around his finger. Klaus said he was looking for Jane-Anne. "Show time," Marcel said.
Marcel led Klaus and his inner circle on a walk through the city, where we saw vampires on balconies and rooftops. It was unnerving even before we realized there really was a mob mentality. They'd all gathered because Marcel was going to confront Jane-Anne about practicing witchcraft beyond the bounds of the rules set forth and enforced by him. She denied it, but he's aware of the witches' every move -- they can't do anything without getting caught. Marcel then killed her and before she died, Jane-Anne had exchanged looks with Klaus, who seemed disturbed by Marcel's display. Klaus was angry that Marcel had killed her before he could find out what she'd wanted with him. Marcel said he never wastes an opportunity for a show of force -- a lesson he'd learned from Klaus. He told Klaus he'd find out what Jane-Anne had wanted for him. Klaus asked if Jane-Anne had a sister.
He went to see Sophie, who was crying. She wouldn't talk to Klaus because two of Marcel's men had followed him. Klaus threatened to rip their spines out, then dropped a $100 bill so the blonde we'd later learn is bartending psychology student Cami could serve them. Klaus had gone to a wild party filled with vampires feeding on humans and dancing badly. He spotted a guy with a day ring, which means he's inner circle, and asked him where Marcel was. Klaus threatened him when he said he only answers to Marcel. Marcel broke it up and said nobody harms his guys. Klaus told him he doesn't need chaperones, and Marcel asked Klaus to just let the witch hunt go. They went out on a balcony, and Marcel explained that more hotels meant more tourists, which meant more fresh blood. He'd taught humans to look away. Klaus wanted to know how Marcel knows when the witches are using magic. Marcel wasn't telling. Marcel chose that moment to take vervain. He wants to limit the number of things he's vulnerable to. He's full of himself, which is why when they spotted clueless Cami walking alone at night below. If she was brave, he'd let her live, and if she was dumb, she was dessert but she proved to be brave. Elijah suddenly appeared on the balcony and told Klaus he'd found out who was conspiring against him. He took him to Lafayette Cemetery No. 1, where Sophie was waiting. "He's all yours. Proceed," Elijah said. She told Klaus that Marcel was out of control and she's going to stop him with his help. Hayley was brought out, and told Klaus he needed to listen to Sophie. Klaus laughed. How could they think this one night stand meant anything to him. That's when Sophie said she has a special gift, which is telling when women are pregnant. Hayley is carrying Klaus' child.
Klaus said vampires can't procreate, which is true. But Sophie said he was born a werewolf -- magic made him a vampire. So he's nature's loophole. Klaus blew up at Hayley telling her to admit she'd been with someone else. Hayley said she definitely would have confessed to sleeping around if she had, because it would have gotten her out of being captive. The baby is his. Sophie said Jane-Anne died performing the spell to confirm the pregnancy, and because of her sacrifice, the lives of Hayley and the baby are now controlled by them. If Klaus doesn't help them take out Marcel, Hayley dies. Elijah offered to kill Marcel, but Sophie said they have rules (and a timeline) that must be followed. Before Klaus could leave, Elijah told him to listen. Klaus could hear the baby's heartbeat. He finally said, "Kill her and the baby. What do I care?" Then, he stormed out. When Elijah caught up to him, Klaus insisted it was a trick. But Elijah saw it as a chance to take everything back. Here, now, is a chance for Klaus, Rebekah, and Elijah to have what they always wanted -- a family. "This is us. The Original family," Elijah said. "And we remain together, always and forever." Elijah said he was asking Klaus to stay there. He'd help him, stand by his side. He'd be his brother and they'd build a home together. "Save this girl, save your child," he said. His response: "No."
Klaus went back to see Marcel, again wanting to know how he controls the witches. They had a pissing match during which Marcel called New Orleans HIS TOWN. He's the one who got rid of the wolves, silenced the witches, and made people look the other way. "I'm not the prince of the Quarter, friend... I'm the king!" he yelled. "Show me some respect." To establish his dominance, Klaus bit one of the inner circle. He told Marcel he'd broken one of his rules and guess what, he cannot be killed because he's truly immortal. Klaus smiled and left.
Klaus walked to Jackson Square, where there was live music and painting. He spotted Cami, admiring the same artist. She doesn't paint, but she interprets art: Every artist has a story, she said. This one was angry, dark, doesn't feel safe, and doesn't know what to do about it. He wished he could control his demons instead of them controlling him. He was lost and alone. Klaus was emotionally fragile enough from a truly confusing evening that he nearly burst into tears.
He'd gone to sit on a bench alone and think. So naturally, Elijah joined him. They talked about how they'd both hated leaving New Orleans -- it was one of the few places they'd ever been happy. "What is on your mind, brother?" Elijah asked. The walls were coming down. It was a different kind of scene than we've ever seen between them. Klaus said for 1,000 years, he lived in fear of settling in a town and having their father chase him out, which made him feel powerless. This town was his home, and in his absence, Marcel has gotten everything Klaus wanted -- power, loyalty, family. Klaus wants what he has. "I want to be king," he said. And what about Hayley and the baby? "Every king needs an heir," Klaus said. Later, Klaus gave his blood to cure the bitten vampire and said he'd like to stay in Marcel's city for a while if he's still welcome. He is.
In his last scene, he was on a street corner and left Caroline a message. He just said he was standing in his favorite place and hoped one day she'd let him show it to her.
Silas pretended to be Klaus in She's Come Undone, taunting Caroline in order to lure Bonnie out of hiding.
Klaus finally returns for Graduation. He saves Caroline and the others from the 12 witches that Caroline had killed. The night after graduation, Klaus and Caroline have a moment. He tells Caroline that Tyler is free to return to Mystic Falls. In the most charming moment of the night, Klaus points out that Tyler is Caroline's first love. Klaus intends to be her last however long it takes. Then he escorts her home. This will mark his final appearance in the show for now.
Klaus made his return to Mystic Falls in 500 Years of Solitude. While Caroline is searching for Matt, she is reunited with Klaus. Klaus wanted to talk to Caroline, but she had no time to chat because Matt was buried alive. "I literally just whooshed at the sight of your face," she told him, using her vamp speed to get away from him. But of course he could keep up. He told her that Damon had let him know that Katherine had taken a tragic turn, so Caroline correctly assumed that he'd come to gloat. He also heard that Caroline and Tyler had broken up. She confirmed it was because Tyler had chosen his revenge fantasy against Klaus over her. Klaus wanted to know if he were to abandon his revenge against Katherine, would Caroline offer him the same choice as Tyler? Meaning, her. Caroline didn't want him to distract her when Matt's life was in danger, but Klaus assured her that he'd heard Matt's call for help and that Matt would be happy with his rescuer.
Caroline and Klaus continued their walk in the woods, and he told her he'd leave Mystic Falls without gloating over Katherine's corpse in return for one small thing. He admits the real reason he’s returned. He wanted a confession. About him. He said as soon as they were done there, he was going to leave and never come back. She'd never have to again cover their connection with hostility and revulsion or loathe the darkest parts of herself that care about him despite all that he's done. He just wanted her to be honest with him. Caroline reminded him of her being in college and her future plans did not involve him whatsoever. Hurt, Klaus understood; but Caroline said he didn't and that he's right about her covering up what she wants. If he was serious about walking away and never coming back, she'd be honest about what that was. After making his promise, Caroline kisses Klaus, further leading to a passionate moment in the woods between them.
In The Devil Inside, Klaus is mentioned when Caroline tells Katherine who is impersonating Elena that she kiss with Klaus and that she felt so good doing it that she ended up having sex with him. Katherine purposely makes that Tyler listen the conversation, he gets furious and Caroline follows him to talk to him, Tyler reminds her everything bad that Klaus made him as how to kill his mother and Jenna. He also appears in a flashback of Katherine's memories.
In Gone Girl, Klaus was mentioned by several characters.
Throughout The Originals Series
In Always and Forever, Klaus is first seen during a flashback to the early 18th century. A crew is searching through an "abandoned" ship and finds the two coffins containing Klaus' neutralized brothers, Finn and Kol. Elijah and Rebekah appear, the latter having fed on and killed members of the crew, before introducing themselves. Klaus, suddenly appearing at the top of the stairs with a dead body in his arms and blood on his mouth, laughs with Rebekah about "leaving the best til last". In regards to introducing them, Rebekah retorts by calling him a beast as Klaus tosses the corpse down the stairs.
In the present, Elijah arrives in New Orleans in an attempt to find his brother and he heads into the bar Rousseau's, in which he strikes up conversation with the human barmaid. He tells her about his brother's paranoia that people are conspiring against him and asks if she knows of Jane-Anne Deveraux. Elijah, after finding out about Jane-Anne's execution, demands to know what she wanted with Niklaus from her sister; Sophie.
As Sophie tells her of Niklaus' predicament, Elijah soon meets Hayley and uses his tactile telepathy in order to show her memories of his human days. He shows her the night that Henrik died, when Klaus carried his body back to the village. He also shows her after their transition, he, Niklaus and their father, Mikael were in the woods when Klaus suddenly dropped, screaming in agony as he began to transform into a wolf, indicating he had recently made his first kill. Later, flashbacks show Mikael and Elijah tying Klaus to a wooden pole as their mother, Esther, cast a spell to suppress Klaus' werewolf side. Klaus quietly begged Elijah to help him, however Elijah followed his father's wishes.
Klaus is first seen in the present standing upon a balcony as Elijah appears behind him, telling him he has found out who is conspiring against him. As Klaus is told of Hayley's pregnancy, he is outraged, believing Hayley to have slept with somebody else and doesn't believe what they are saying is the truth. As he leaves, he snarls for them to kill Hayley and the baby. Elijah follows him outside in order to get him to change his mind. Elijah's words don't pacify him and he continues to deny the pregnancy and that it will not give him power, and that he isn't willing to be manipulated by the witches.
Klaus is then later seen with Marcel, observing the courtyard, the vampire's and loud music. He converses with Marcel over trivial matters, however begins to grow increasingly annoyed with the younger vampire when he calls New Orleans "his town". Klaus huffs that before he left 100 years ago, Marcel was a "pathetic little scrapper still trembling from the lashes of the whips" of those who brought him down as a child. Marcel knows he is jealous and snarls that it is his town, that he is the king. Klaus stands for a few moments, the music quietening down as people observe the scene, including Elijah from afar. Klaus smirks before quickly turning and biting one of Marcel's closest vampires, infecting him with his bite. He says to Marcel that he broke one of his rules yet he is immortal and cannot die, walking away saying "who has the power now, friend?"
The witches told Elijah that Klaus had until midnight to change his mind about the child and Hayley's life before they die - as Jane-Anne's spell linked Sophie and Hayley together. As Klaus is heavily drinking around a back lot in the quarter, he smashes a bottle upon the floor, knowing Elijah is behind him. Klaus tells him to stop harping on about the baby and Elijah vamp-speeds towards him, determined to knock some sense into him. The two begin scrapping and Klaus knocks Elijah off him before the latter returns, saying he will belt him like "their father used to", in order for him to regain his humanity. Klaus calls him pathetic and a "sentimental fool" as Elijah tries to mention family once more. Elijah walks off, leaving Klaus to ponder the events.
Klaus is later sitting upon a bench, seemingly having thought about things, when Elijah sits down next to him. Klaus solemnly reveals that the town was his home once and that he wants it back, that he wants to be king again. Elijah asks if that is all the child means to him before saying the child could change him, give him something he never believed he had; unconditional love of family. Klaus then looks at him and tells him to tell Sophie that they have a deal. The next day, Elijah is helping Hayley unpack things in their new house, which was co-incidentally their old house when they lived there and tells her he would always protect her. Klaus appears, taunting "noble Elijah, keeping his word". He then tells Elijah he healed Thierry, and that Marcel thinks he is on his side again.
Elijah and Klaus are talking in another room, taking sheets off their old belongings. Klaus says that they can destroy Marcel's army from the inside. Elijah asks about Rebekah. Klaus knows that Rebekah doesn't care and that he "shoved her in a box one too many times" and the elder brother says she will hopefully come around. Klaus, reaching down beside an object says he hopes Rebekah stays far away as there is a weakness in Rebekah that Marcel would exploit. Elijah asks what that is. Klaus simply looks at him and says "you" before quickly shoving a dagger into his chest. As Elijah desiccates, Klaus says family is a weakness and that if he is to win this war, he has to do it alone.
In House of the Rising Son, Klaus has stayed in New Orleans for three months. Klaus and Marcel are standing on the balcony of the Abattoir and Marcel is telling Klaus that they lure humans to his club and at midnight they feed on them, Klaus questions Marcel about what they do with the bodies and he reveals that they feed the vamp blood to avoid any suspicion. Thierry comes up to them and informs Marcel of that six of Nightwalkers has been killed in a bar.
Later at his house Rebekah has arrived, she demands to know what he has done to Elijah and he does not say but hints that he has daggered Elijah. He asks Rebekah if she was the one that killed the 8 Nightwalkers, which she admits to have done. Klaus brings up Marcel and his rules when Rebekah claims that he does not have any friends. He gets a text and is about to leave when Rebekah asks where he is going, he tells her is going to have drink with Marcel. Rebekah questions what part it has in his plan to undermine Marcel's empire and Klaus reveals that when friends drink they tell secret and he is hoping to learn what allows Marcel to control the witches and take it for himself.
He finds Marcel at a bar looking at Camille. Marcel tells Klaus that two of the guests from the other night are dead and are now in transition (Josh and Tina). Klaus gets up and talks to Camille and he sets up a possible date between her and Marcel. Later Marcel brings him to a van with Josh and Tina inside. Marcel throws a coin and the one that pick it up gets to become a vampire and the other will die. Tina picks it up but Marcel kills her when she betrayed Josh. Klaus escorts Josh into a car.
At a bar Klaus is having a drink and Marcel comes in and is angry because he didn't tell him that Rebekah is back. Marcel asks him there is anything more that she needs to know, like if it was her that killed his 6 nightwalkers which he denies. Marcel then gets a call, saying there is a werewolf in town. Klaus returns home to find 3 dead and 1 living vampire at the house, because Hayley left the house. Klaus is furious with both Hayley and Rebekah and yells at them that they put his plan in peril, Rebekah defends herself by saying she was protecting Hayley and says that Klaus has done nothing to honor the deal that Elijah made for his child. He responds by saying he has done everything and tells Rebekah that since he came to town Marcel has not trusted him and has had his men ingest vervain, so when Marcel lost 6 nightwalkers he killed Josh ans Tina and he compelled Josh into becoming his spy as he had not been given any vervain yet. Then he compelled Cami into dating Marcel and to be his spy. He drags Max into the house to drain him of vervain and compel him. Still angry with Hayley he demands to know what she was doing it Quarter in the first place. Hayley snaps and tells him that she was buying poison to kill the baby. Enraged by this Klaus grabbed Hayley by the throat and begins to choke her, showing that he cares about the child. Rebekah intervened and told Klaus that it is okay to care and to want something. Klaus sits down next to his sister and tells her that he gave Elijah to Marcel as a peace offering.
The next day he enters Hayley room to see if she took the poison or not. Hayley tells she didn't take the poison. Klaus asks her why didn't use it and she said it was because of that both her birth and adoptive parents abandoned her. Hayley asks what happened between him and Marcel. Klaus replied by saying he made Marcel what he is and treated him like a son and after Mikael chased him and his siblings from New Orleans, they all believed that Marcel had been killed and they mourned him. Then after he returned he did not only find that Marcel had survived, but he had taken everything that his family built and made it his own. And now he is living in their home, sleeping in their beds and the letter M that he stamps everywhere is not for Marcel it is for Mikaelson. Klaus also tells that he wants it back and if he has to push Marcel to get it, that is exactly what he will do.
In Tangled Up In Blue, Klaus sets the 3 dead vampires on fire and the next morning Hayley asks both him and Rebekah what the plan is to get Elijah back. Klaus say there is plan A: ask Marcel for Elijah back and then there is plan B: war. Klaus goes through with plan A and asks Marcel for Elijah back, but he says no and invites him to the party he is going to host.
He is later on the phone with Rebekah while Josh is draining Max of vervain. Rebekah tells Klaus that she is going to deal with Sophie and Katie the witch that rated out Hayley. Klaus walks to Josh noticing that he is not draining the vervain out of Max fast enough and drives a pitchfork through Max and compels Josh to do the same. Josh not knowing why he did it ask how Klaus made him do it and he explains how compulsion works. Rebekah calls him again and informs Klaus of that Katie is the girlfriend of Thierry, making him the key element in the plan.
Later Klaus and Rebekah were having a talk with Sophie asking her to do a tracking spell in order to find Elijah and Davina at the same time. They also ask her to play a part in their plan and have Katie use magic so Davina won't sense the locator spell. Klaus reveals to Sophie that Katie was the one that got he sister killed to motivate her.
Klaus has a talk with Marcel and convinces him that the witches a planing something and Marcel has Thierry bring some nightwalkers to do a rousting with the witches, all part of Klaus plan. Klaus later talks with Rebekah over the phone and tells her that he compelled Max to feed on Katie, which made Thierry attack Max and kill him and that will leave Marcel with no choice but to punish him and Katie will try to save Thierry.
Later Klaus attends Marcel's party with Rebekah and he sees that Rebekah has invited Cami as a distraction and payback against Marcel. When Marco tells Marcel what Thierry had done, Klaus just watched on as Marcel furies talked to Thierry and then he sent Josh to bring Marcel the spell to make daylight rings, saying that they found it in Katie's store. This left Marcel even more angry and he sentenced Thierry to the Garden. As Marcel and his vampires are escorting Katie shows up as planed to save Thierry, giving Sophie time to cast a locator spell. While Katie attacked the vampires with her magic, she got close to kill Marcel until Klaus saved him by killing Katie.
Klaus and Marcel later have a talk involving Thierry. Marcel then thankful for Klaus saving him will give him back Elijah. Marcel then asks how much Cami saw and Klaus tells him that she only saw a argument nothing that can't be fixed. Klaus walks into the bar and he sits down next to Cami and tells her that he needs her to give Marcel a second chance and compel her to do so. He returns home to hear Rebekah say that they failed which Klaus said is not true and he reveals that he was the one that killed Katie and he knew that she would try to take out Marcel. He also reveals that he was only using Sophie as she and the other witches only wants to have Davina and he is going to take her for himself before anyone can.
Klaus goes to Hayley to tell her that Elijah will be returning soon and as he is about to leave Hayley stops him a tells him that she thinks the baby is a girl and Klaus leaves the room with a smile on his face.
In Girl in New Orleans, Klaus offers Cami the job of write his memoirs, giving him time to compel her into spy on Marcel. Klaus tells Camille the truth of the war between vampire and witches, Cami reacts badly and Klaus compels her not to be afraid and she asks him how he made her feel safe. Klaus tells her about compulsion an d then sits down and proposed that they talk more about Marcel.
Klaus goes to visit Cami and she asks how when he comes up to her she remembers what Klaus told her that he is a vampire and when he leaves she goes ask to thinking that he is a hot guy, with an accent and money to burn. He reveals that it is how compulsion works and he suggests that they sit down and that Cami tells her what she learned about Marcel. She tells him that Marcel has asked her to look after a young girl at the music festival an she says she sad no. Klaus then asks her to reconsider without compulsion, Cam asks why he asked politely and he reveals that he likes her and how her mind works and believes that they could be friends under other circumstances . He then compels her into doing what he asked for.
At home he sees that Rebekah is still trying to use the internet to find Elijah. He how it's going and she tells him that she remembers that there was window shutters behind Elijah's coffin. He points out that it is like trying to find a needle in a haystack. Klaus then brings up that due to the delay of Elijah's return he believes that Marcel is no longer in charge of the situation. And because of that he suspect that Davina's loyalty to Marcel has been strained, perhaps Davina is open to other alliances. Rebekah the comments that as usual he is power is more important than getting back their brother, Klaus chose to see it as killing two birds with one stone. Take Davina and get Elijah back. Klaus later compels Davina's friend Tim to make Davina visit and he tells Cami to give Davina a note and say it was from Tim and sneak Davina out through the back door.
Later at a church Klaus sits next to Camille as they watch Tim play his violin and Cami brings up the killing of nine people that took place at the church and asks him if he has ever seen a man just snap and go on a killing spree. He tells Cami that he has seen a lot in his time and has learned that that the world is a awful place. Cami responds by saying that the world and people are not awful, they want to be good and something makes them bad. She also says that there is also signs of when someone is going through a psychotic break and the guy responsible did not have any. Klaus says she is well informed on the matter and realize that she knew him, Cami reveals that it was her twin brother Sean. She says that she can't sleep because she dreams about what Sean did and she hates it. Klaus tells her that the must all stand alone against with their demons and Cami answered by saying what if one day his demons they become my to. Then Klaus compels her to leave and forget what happened.
Later he interrupts Davina and Tim and compels Tim to go sit down while he talks to Davina. Klaus tries to convince Davina to switch sides. He tries to convince her that Marcel is not her friend and that he is only using her and Davina respond to this by boiling his blood and Klaus grabs Tim and threatens to kill him. Davina tells him to let Tim go and breaks Klaus leg but i heals and Klaus tells her he will let Tim go but only if Davina will swear allegiance to him alone. Davina gets even more angry and lashes out at Klaus with her magic. Davina's lose of control knocked her out and when she woke up she ran outside to look for Tim giving Klaus time to talk with Rebekah over the phone who revealed that Hayley is missing and she was attacked by wolves and when she woke up they were all dead.
He tells her to keep looking and that he is on his way. Klaus then threw Tim down the church balcony. Then when Davina found the injured Tim. Klaus offers to heal him as long as she says please. She does what he asked and he healed Tim. He then compelled Tim to forget ever meeting him and Davina that night and tells Davina that she owes him a favor.
Klaus later arrives at the location of Hayley's disappearance and asks who took Hayley and ho killed her attackers she say she does not know. They then hear a wolf howling and they go outside to find Hayley. Klaus worried about the baby goes to her to make sure that she is okay and notice that she has completely healed and she says it's because she's a werewolf but Klaus she can't heal that fast. Rebekah tells him to leave her alone and realizes that the baby's vampire blood healed Hayley. Rebekah tells both of them that she has been in contact with Elijah and he has a plan. When Hayley gets up she almost collapses and Klaus catches her and brings her home.
That same night Klaus went to visit Camille. She invited him in and asked him if a vampire could have compelled Sean into killing nine people. Klaus then asks her to what end will learning what happened to her brother. Cami responded by saying that is the only reason she is on New Orleans . Klaus then tells it will bring her nothing but pain and it won't bring her brother back. He tells her the only way for her to find peace is for her to move on and forget. Cami understanding that he is going to compel her she asks him not to but he says it will only eat away at her and it will only put her in danger. Cami the says that he doesn't care about her he only wants her to be a good little spy. Klaus tells her he needs her loyalty but it is honor his brother the Cami asks what about her brother and says she needs to know who did it and make it right. Then Klaus compels her to move on and he promise her that he will find the one who harmed her brother and make them suffer.
InSinners and Saints, Klaus grabs Sophie and brings her to his house accusing her of breaking their deal by letting Hayley be attacked by witches. Sophie swears that she did not have anything to do with it and it was a faction of extremists that were behind it because of a vision Sabine had about the baby. Klaus asks what she saw and Sophie reveals that Sabine saw that the baby will bring destruction to all witches. Rebekah asks how extreme the faction is and brings up that Elijah is talking to Davina. Sophie the says that Davina will have much to say about the faction and Klaus tells her to tell them what she knows and she reveals that she did not like the strict way she was raised so she left to travel and play, but she returned eventually and she learned from her sister Jane-Anne that hey are going through with the Harvest a ritual preformed every 300 years in order for the witches to keep their power granted to them by their ancestors. They are interrupted in the story when Marcel calls Klaus to tell him that there has been a attack on witches in the bayou and the injuries are consistent with that of a werewolf and he wants Klaus to come with him.
Later he is at the Big Auggie's Biker Bar and is on the phone with Rebekah and she tells him to stall Marcel from finding them. In order to do so Klaus asks Marcel some questions one being how he met Davina. Marcel reveals that it first started 8 months ago when he had a sexual relationship with Sophie and she to him about the harvest. The Klaus asked who Sophie turned to and Marcel reveals that Sophie turned to Kieran a priest, leader of the human faction and Cami's uncle. Kieran tried to convince the witch elders to not go through with the harvest, but to no success. In return for Kieran attempt to stop the harvest one of them put a Hex on Sean to distract him.
Later Klaus gets a call from Rebekah telling him that they went to the bayou and they were seen by a vampire who might be Marcel's informant Thomas and they lost him. Rebekah tells him to handle it and he says that he needs a distraction and Rebekah says that she is on her way. He then returns to Marcel and asks him what happened next. Marcel tells him that when the harvest was preformed the witches killed the chosen four, but before they could kill Davina Marcel showed up with his army and they stopped the ritual and when Marcel saw Davina being held by a witch trying to get free Marcel saved her and Marcel tells Klaus that there was something in the way that she fight to know and Klaus respond by saying I do Marcellus reminding him of how he once saved Marcel as a child. Marcel continues to tell the story and when the other three girls had been killed Davina was given all of their power and that is what makes her so strong.
Rebekah later shows up to stall Marcel giving Klaus time to find Thomas and snapped his neck. He then returned inside and asked Rebekah where Marcel is and she asks him the same thing and they realize that Marcel was stalling them.
Klaus the waits at the Abattoir for Marcel and when he shows up he tells his son that his attempt to stall him was pathetic and he taught him better than that. Marcel responds by saying that Klaus taught to protect what is his and says you will not take Davina from me and Klaus says that the strong always take from the weak. Marcel responds by saying if he is so strong why did he run from New Orleans, this enraged Klaus and jumped from the balcony and punched Marcel in the face. He says that he can take Davina when ever he wants and when Marcel is about to attack he is but not by Klaus, by Elijah.
The brothers later return home and Elijah gets the family to tell them that the reason that they were lured back to New Orleans was not because of the war between witches and vampire, it is because of Davina. He says that Sophie and Jane-Anne lost everything when Jane-Anne's daughter Monique was killed in the harvest and Jane-Anne sacrificed herself to bring her daughter back, so it is about family. He also tells them that Sophie is the greatest threat against them because she is willing to give her life to kill Davina and bring Monique back to life.
In Fruit of the Poisoned Tree, Klaus attempted to buy his brothers forgiveness by offering him a girl to feed on, but Elijah refused as forgiveness can't be bought. Then Klaus feed of the girl instead and left her body on the table. Afterwards the brothers began to ignore each other and sat down right in front of each other and read. Later Elijah rips out a page from their mother's spell book and he informs Klaus and Rebekah of that he intends to use Davina to break the link between Hayley and Sophie and he also reveals that their deal with Sophie no longer stands. Klaus is then told by Elijah to accompany him to the church and stay guard so Elijah can have some time with Davina.
Klaus and Elijah arrive at the Rousseau's and they find Sophie and Sabine knocked out. Once Sabine awoke they questioned her and she revealed that Sophie had been taken by Agnes. She refused to reveal where Agnes, believing they would kill her if they found her but when Klaus made it clear that he does not care about the harvest or Agnes she gave them her location.
They arrived at a crypt and found Sophie chained up and she revealed that Agnes used a cursed object on her that will affect Hayley and kill Klaus' baby. After learning this Klaus went to The Faction to ask them to find Agnes for him. When the leader Kieran asked him why they should to this Klaus reveals that Agnes is the witch that hexed his nephew Sean into kill himself and nine priests. This convinced Kieran to find her and he asked Klaus form some time and he screamed at Kieran that he does not have time, but Kieran didn't even flinch to it and stood tall against him this impressed Klaus and he gave him one hour.
Later he catches Kieran leaving the church and he offers Kieran a deal; Kieran will bring Agnes to the church and Klaus won't harm Camille. Kieran does what they agreed to and Klaus asked Agnes how to undo the curse she placed on Hayley. Agnes says it can't be reversed and his child will die. After Klaus learns that the link has been broken and his child is safe he tells Agnes that he is going to leave pieces of her at her family crypt, believing that it will send a fitting message; no one hurts his family. Then Elijah comes to the church and Klaus grabs Agnes. Elijah tells him to let her go and in return he will give him his forgiveness. He does as his brother asks and after he says that it is much like him to spoil his fun Elijah attacks and kills Agnes.
Klaus later goes to Cami to tell her that he learned what happened to her brother and he reveals that Agnes is dead which angers her because she did not ask him to make her part of revenge ans she swears that she will find a way to undo what he has done to her.
As he is walking on the street Marcel confronts him and reveals that he knows where he lives and he saw Hayley. Klaus the hurried home to find that Hayley is gone and he tells Elijah that Marcel was there.
InBloodletting, Klaus is at Marcel's Fight Night. Him and Elijah interrupt it to ask Marcel where Hayley is. Marcel doesn't know where she's at and tells Sabine to assist Klaus and Elijah. Sabine performs a spell and reveals that Hayley is in the bayou. Klaus and Elijah drive there together and search the bayou for any sign of Hayley.
Eventually, Klaus discovers Tyler is holding Hayley captive. Hayley fled into the woods. Soon after, Klaus and Tyler confront one another, argue and then battle. Tyler, being no match for Klaus, is defeated with little difficulty. He did however, manage stab Klaus through the chest.
Later on, Klaus is found at the cabin by Hayley and Elijah and the three get into a heated argument about family and the recent events that are unfolding. Klaus, not pleased by Elijah, bites him which will make Elijah weak. He returns to the house and is talking to Rebekah about the situation. Rebekah informs Klaus that he never actually understood why Elijah cared for him and Klaus admits that he's in the wrong.
In The River in Reverse, Klaus is having breakfast with Rebekah. He is first seen filling a glass with blood from a woman's arm and whilst doing so he asks Rebekah if she has seen Marcel, intending to find out why he has been avoiding him and draw attention to Rebekah and Marcel's relationship. Klaus speaks to Rebekah wondering why she is giving him a "devil stare", assuming it is because he bit Elijah. Rebekah answers saying that she is worried Klaus would bite her also if she were to voice her opinion, however Klaus states that he would never bite her and that his preferred method of punishment is a dagger.
Next, Cami is recording Klaus' memoirs on a typewriter as Klaus speaks. Klaus is ranting about his disappointment in his siblings and he finds a mysterious drawing of Cami's; she mocks him by saying that it's a plot to destroy him and then a tattoo design.
Klaus then surprises Josh by turning up at a building where he is working on a car and says that he has the "role of a lifetime" for him. In a scene between Rebekah, Marcel and Josh, it is revealed that Klaus tried to compel Josh to steal a dagger from Marcel, however the compulsion didn't work because Davina removed the previous compulsion of Klaus from him. Josh does not get the dagger for Klaus but does what Marcel asked him by telling Klaus that Marcel has it on him.
Klaus goes to visit Cami's uncle, the priest, in hopes of getting him to persuade Cami to leave New Orleans. Afterwards he goes to confront Marcel, unaware that Rebekah had schemed with Marcel to subdue him. Before the start of the fight Klaus throws a coin and states that whoever picks up the coin will get to live, but nobody picks up the coin and the fight begins. Klaus kills two vampires that attack him and cockily puts his arms out. The tables turn on Klaus because chains are wrapped around his arms and he is dragged and then beaten up to the point of being on his knees. Klaus then growls and displays his hybrid eyes. He breaks free of his chains and begins to attack and slaughter the vampires around him. This continues but Marcel stops the fight, then he picks up the coin and pledges his allegiance to Klaus; after Rebekah tells him it is the only way to stop him killing everyone. At the burning of the deceased vampires from the fight, Klaus and Marcel have a conversation in which Klaus makes it clear that he wants his home back and Marcel agrees.
Klaus later feeling betrayed, holds a dagger to Rebekah when she confronts him after the fight, but then lets her go upon Elijah's arrival and demand. Klaus then says to Elijah that maybe it should be him he daggers because he feels that Elijah will replace him as a father to his child. Rebekah comments that they do not abandon him, he drives them away. Klaus then, hurt, says that he has done nothing lately but co-operate and bow down to Elijah while Rebekah is with a man she shouldn't be with, who stole their home from them. He also says that it was them who let him down by not believing his intentions for his child were pure. Klaus leaves with tears down his face to go to his reclaimed home with Hayley, stating that the child is the only thing that matters to him.
In Reigning Pain in New Orleans, Klaus tries to gain trust of the quarter vampires by telling them that he has no intentions to create more hybrids which could harm them. To win their trust in this matter he allows them to kill off the werewolves in the bayou so that they could be sure that he doesn't want to use his child this way. He is still upset with Rebekah and Elijah and is taking away their furniture and seeks comfort from Camille. He compels her to write his memoirs as he is upset with his siblings. Camille is mad at him as she knows that Klaus uses her as therapist and blames him from messing with her mind. Klaus tries to confirm his grip over the down and asks help from Marcel. He confesses to him all the things he did to win his home back. He also asks Marcel's help to move Davina closer to him as he would like to have such powerful weapon close by. Klaus then has meeting with the human leaders who want bribe for their silence as vampires rule this city. They also want to set rules on Klaus how they want him to behave to protect the locals. Klaus laughs at their face and says that they are lucky to have whatever he wants to leave them, because other way they have lost their usefulness.
Soon after meeting the council calls him to tell him that they don't accept his terms ant they attack him and Marcel as they are in the bar with other vampires. Many vampires die and Marcel blames Klaus for it as he failed to make peace with humans. Klaus and Marcel call a human council meeting where they take revenge for their vampires leaving only father Kieran alive. Klaus tries to make Marcel his friend again and tells him that his decision to take over the city was not entirely his own. He reveals to him that the witches would have killed his unborn child if he would have refused their bidding. He says that he will not be a bad father to child, as his step-father was to him and admits that he was jealous for Marcel having created this empire without him. Klaus realizes that he can rule the vampires, but he can't win them so he asks Marcel to rule with him as his equal.
Later he has to deal with Hayley who is angry with him because of his order to kill the werewolves. Klaus tells her that he did it partly to ensure Hayley's safety as it lessens the threat to her from the vampires who otherwise would like to kill her. Afterwards he meets Rebekah and Elijah who declined his rules and ended the werewolf hunt as they found out that their clan is connected to their mother. Rebekah says that they are trying to make amends for their recent behavior and they found the clan of his father's bloodline. Though they ask for his forgiveness he asks them why would he want it and leaves them. He went straight to father Kieran to ask him a favor to protect the werewolves in the bayou from himself and other vampires without them finding out about it. In return he is asked to set Camille free. He goes to her and tells her that he is a monster and shows him memories from his past, but Camille feels sorry for him not disgust. He says to her that knowing about this world will only get her killed and then he compels her to leave New Orleans and forget everything she has learned about vampires. at the end of the episode he forgives Elijah and tells Elijah that when he and Rebekah are ready they are welcome to join him.
In The Casket Girls, Klaus calls Marcel as he discovers that Davina has escaped. As Elijah and Marcel are discussing how to get her back, Klaus has a plan of his own. They go to the Casket Girls Festival and Klaus searching for Davina. Klaus finds Davina's friend Timothy and kidnaps him to lure Davina out. Then he calls Joshua to send his message to Davina. Davina comes to Klaus to get Tim, but she doesn't cooperate and attacks them ( Klaus, Marcel, Elijah) and overpowers them.
While Klaus is out cold, Davina leaves with Rebekah who wants to make her an ally. As Davina showed him clearly that she is not on his side Klaus had a back up plan. He had compelled Timothy before he was knocked, to poison Davina and Himself in case Davina doesn't return to him. As vampire blood is not curing the poison Rebekah calls Klaus to ask how to save her, but Klaus refuses to help her. Then Elijah and Marcel reveal to him their own plan which they made in case if Klaus goes to far. They had made a deal with a witch to protect Davina from dying which leaves Klaus still dealing with the witch problems. When Davina is safely returned to him Klaus takes her back without revenge on Marcel or Elijah for plotting against him. Later he meets Camille on the street and discovers that Davina has undone all the compulsion on her so she remembers everything.
In Après Moi, Le Déluge, at the beginning of the episode Klaus is first seen talking with Elijah while Davina is starting to lose control over her power. When the earthquake starts, Klaus runs to Davina's room and discovers that she is coughing up dirt. As he realizes how great is Davina's power he soon begins to worry about the consequences and asks Marcel how to control her. Soon they find out that Davina's power is going to have four phases as she releases all the elements - earth, air, water and fire, making him worried about New Orleans. as they realize that the only way to stop Davina is to complete the Harvest and is trying to make Marcel agreeing with this. Marcel opposes him and doesn't want to hand Davina over for the sacrifice and takes her away from Klaus. Klaus, Elijah and Rebekah combine their forces to find Davina before she destroys everything. He also tries to make sure that Haley is safe and helps her with her plan to aid werewolves. He shows Haley that he has already taken care for the werewolves and tells her that they are also his clan. Then he asks Kieran to help him find Davina. Klaus and Haley are having a moment when he advises her to just apologize to Elijah to fix things between them. As Sophie's plan to get power from Celeste's bones fails, Elijah comes up with the new plan involving the Originals. They decide to make their mother Esther a New Orleans witch so they could channel her power and finish the harvest ritual. They bury their mother and take her power but something goes wrong and the girls who were killed for the harvest don't resurrect.
Marcel blames Klaus for Davina's death and this is making another barrier between their relationship. Klaus hugs him and tells him that he understands, because after he fled New Orleans he thought he was dead and it took him years before he could even speak his name. When he goes home he talks to Rebekah and asks her how did she find Davina so quickly and they share their regret over their failed plan to save her. When Rebekah realizes that this power could not have just vanish it leaves them with another problem to solve.
In Dance Back from the Grave, we can see flashbacks from his time in New Orleans from 1919. He tried to make arrangements with werewolves in this city, so his rule could remain hidden. But their meeting is soon interrupt by a witch named Papa Tunde, who demands to know how it would benefit for the witches. He demands a tribute as he thinks he is also the king in this city and brings them the head of the mayor who he has killed. Klaus doesn't like it and decides to find out who this enemy is. Klaus befriends him to find out his weaknesses so he could destroy him. With help from Marcel he finds out that Papa Tunde channels two twin witches who always accompany him and kills them to get rid of this rival. In the present time he is in very good mood after his trip to Mystic Falls. He frees Thierry at Rebekah's request. Then he informs other vampires in the quarter about Davina's death and the unsuccessful Harvest. He tells them that since Davina is dead they can't any longer control the witches in the quarter. So he orders them to keep them busy, until their power fades. He puts Diego on charge and is disturbed when Marcel doesn't join them. He talks with Marcel about his attitude but they are interrupted by Diego who has found some dead vampires. As they find two dead vampires, who are not even staked he wants revenge and make them suffer. He tells Diego to gather all the vampires and found out who did this, but most of the vampires are too freaked out to help. He realizes that others are so afraid of this new threat he decides to find the answers himself. On his way to figure things out he meets Sophie and finds marks of a dark sacrificial magic.
Soon he gets the call from Camille who tells him that Papa Tunde is killing Marcel. He runs to save him and confronts Papa Tunde himself, who is has all Rebekah's power so he is stronger than Klaus. He almost takes Klaus down, but Elijah and Hayley break the spell so that he loses power over Rebekah and Klaus overpowers him. He finds Marcel dying and tells Camille to find him somebody to give him blood. Camille volunteers, much to Klaus's dislike, but he allows her to save him. As he thinks the war with the witches has just started he asks the vampires in the quarter who will stay with him. Few leave, but most of them stay with him. He asks Sophie how could Papa Tunde return and finds out that it was because of the stolen Harvest power. As they learn that the Harvest might not be over he has Marcel back, because he will side with him to get Davina back and end this witch war. They want to stop him from killing more vampires and are alert that the garden is dangerous place if Papa Tunde discovers it, but they are too late. All of them are dead, leaving Klaus facing a stronger enemy.
In Crescent City, Klaus is first seen in St Anne's church with Marcel to celebrate the reopening of it. They want Father Kieran to find out all that he can about the witches. Klaus gets a call from Diego who informs him that Papa Tunde is dead and they start to understand that their witch problems are only getting started. When he gets a message from Camille he meets her at the church and she asks for his help with her uncle Kieran, who has been cursed like Sean. Klaus comforts her and tells her that her uncle is a good and loyal man. Camille asks his for help and gives him Papa Tunde's knife, which she was asked to stab into his heart, but she chooses Klaus over witches. Then Klaus and Camille are going to father Kieran and are bleeding him out so Klaus could compel him to overcome his dark curse. When this is done he goes to seek out the witch who hexed Kieran in the first place. He takes Monique for leverage to lure them out, but Marcel does not approve of his plan. Marcel attacks him so Monique could escape and when Klaus fights him off he drops the blade. When he turns around Sophie pushes this blade to his chest. Klaus is screaming in unbearable pain and then collapses, leaving him to the hand of of his the enemy.
In Long Way Back From Hell, Klaus is completely paralyzed by the blade inside of his heart. Genevieve removes the blade from his heart and Klaus awakens in a weak state. He asks Genevieve why she is so kind to him and she says he never did anything to her and she can't help but pity him in his current state. She gives Klaus a brew made with magic and he drinks it willingly and Genevieve reveals that she will show him his sister's betrayal and that is how she will have her revenge against Rebekah. She shows him how Marcel and Rebekah snuck around behind his back and he already was aware of this and tells her if it's part of her plan to turn him against Rebekah it is ineffective. Genevieve says that is not even close to the full extent of their betrayal.
Genevieve later revealed that Klaus' fear of Rebekah and Marcel's love had led to them conspiring to get rid of him. He is shown that Rebekah had manipulated Genevieve into summoning Mikael. Klaus is greatly affected by this and screams to Genevieve that he has had enough of her lies. Genevieve says that he must have known that Rebekah was responsible for calling Mikael, or at least suspected and Klaus refuses to believe that Rebekah had taken everything he had accomplish away from him. Genevieve responds by saying that when she is done he will realize how wrong he is.
Genevieve shows him more proof of what Rebekah did and this time he sees when Genevieve cast the spell that called on Mikael with his half-sister and Marcel present. During the ritual he sees Mikael's blade that went missing when Klaus was a boy and Mikael beat him half to death because he believed that he had stolen it, and he should have known that Rebekah had taken it as she was so kind to him the weeks after the beating. After the vision has ended he knows the truth and screams out Rebekah's name in anger. Genevieve also shows him how Rebekah killed her.
Genevieve apologizes for what she did and says it was necessary for him to see so he can take his and her revenge. She offers him her wrist so he can regain his strength and he accepts it. She then releases him and gives him Papa Tunde's Blade. Klaus speeds off and begins to search for Rebekah. When he finds her she claims that it isn't true and he wants to believe her, but her face tells a different story and she begins to run.
Rebekah soon stops and Klaus comes down the stairs and reveals that he is no longer going to dagger her, he will use the blade on her and he describes what it's effects are, she tells him to do it. Klaus says that he is disappointed that she is not begging for mercy and forgiveness. Rebekah responds by saying that it won't do her any good and when Klaus asks how her father would look at her now, she attacked him and he threw her through a wall. Rebekah grabbed a metal bar and began to hit him with it but he easily defeated her and had her on her back. Marcel then came speeding in and Klaus threw him into a wall and was happy that he could kill him now. He tells Marcel that he will make Rebekah watch Marcel die and Rebekah claims that it was her idea to call Mikael and he turns to her and is about to stab her with the blade, but Elijah arrives and turns the blade on him and he is once again under the effects of the blade.
In Le Grand Guignol, Elijah removes the blade from Klaus' heart and asks Camille to look after him and slowly feed him her vervain laced blood, so he will recover slowly. When Camille asks him how he can hate his sister and he reveals that she has done something no one has done in over in a 1000 years; ripped his heart out. He begins to tell her that he allowed Marcel and Rebekah to be together and now realizes that he was a fool for not seeing their treachery, as they brought Mikael to town. Camille then assumes that he is consumed by revenge he will not achieve. Klaus responds to this by saying that he is not so sure because if they are going to run from him they will need a cloaking spell and for that they need a witch.
Later, Klaus tries to get up but he is still weak and Camille stops him from doing so. After Camille makes a joke about him he tells Camille more of the story and reveals his relationship with Lana and it led to him getting tickets to the opera. Camille then says she is not surprised that he likes opera and he respond by saying that he has always had a softspot for the Le Guignol and says it reminds him of what happened in 1919.
When he pours himself a drink, Camille then enters the room and when she mentions Elijah's name Klaus tells her not to speak to him about Elijah. Camille says that Elijah loves him and he agrees with her, saying Elijah proves time and again, even when Mikael enlisted Elijah to kill him. Klaus tells Camille that Mikael came to Elijah and wanted him to help Mikael to kill Klaus. Camille then interrupted him by asking him why he says kill when he is immortal and can't be killed, and Klaus reveals that he can be killed and Mikael had the one thing that could kill them; the White Oak Stake.
He continues to tell the story and tells Camille that Elijah refused Mikael's offer and said he would always stand by his brother and as a reward Mikael stabbed him with a piece of wood. Klaus says that Elijah often felt guilt for not stopping Mikael and Klaus would tell him not to blame himself. Klaus then received a text saying that Rebekah and Marcel have been seen in town. He then breaks a statue and pools out a stake. Camille asks what it is and he reveals that it is his own White Oak Stake.
Klaus is later feeding on a guy and Camille comes out to ask him what he is doing and he reveals that he is going to kill Rebekah. Camille then tells him not to kill his sister because if he does he will be filled with guilt and he won't survive it. Klaus responds by saying that he almost didn't survive Rebekah bringing Mikael down on him. Camille then tells him not to hunt down and terrorize Rebekah and Marcel, like he was terrorize, because if he does it he will become his father. Klaus then says he has been called many shades of monster but that was new and he says that Mikael was the monster that monsters was afraid of. He then grabbed her to show her something. He brought her to the location of the opera that burned down in 1919 and reveals that it was the work of Mikael. He tells her how Mikael sat behind him with his stake aimed for his heart and when Klaus said that if Mikael killed him he would fall proud of what he had achieved. Mikael then agreed with what he said and revealed that after he killed him, he would kill everyone that remembers his name. Then as the show started it showed that Mikael had compelled the audience to applaud to what they where seeing; Lana impaled on the scene and Marcel chained to a x. Klaus reveals that he tried to save Marcel but Mikael stopped him and Rebekah intervened and Klaus says he believed that she was trying to save him all those years, and now realizes that it was Marcel she tried to save. He continues to tell Camille the story and Elijah came to help them and together they ran and as they fled Mikael burned the opera to the ground along with Marcel they assumed. He says he lived but all that they built died as did the last shred of him that felt human and says that is what Mikael took from him that night. Klaus then assured Camille that he was not going to terrorize Rebekah and Marcel for centuries, nor will he torment, humiliate or dehumanize them, he will just end them. Klaus then speeds away before Camille can respond.
Klaus enters the cemetery and he screams for Rebekah much like Mikael screamed for him when they where leaving the city. He found his sister with Elijah and he told him to get away from Rebekah because she is his. He then puts his Hybrid face on and Elijah and Rebekah did the same.
In Farewell to Storyville, he is in the cemetery with Elijah and Rebekah. He holds a hearing for Rebekah and she confesses what she did in 1919. He shows anger and goes after her when he possibly can. Elijah defends Rebekah and tells him what Mikael also did to them besides Klaus. Klaus stabs Elijah with the blade and then goes after Rebekah. He confronts her again and she tells him the truth. He shows sadness and stabs Rebekah with the White Oak Stake. Revealing that he missed her heart, he asks her what she wants. She tells him she wants what she always has: a family and a home, and he exiles her from New Orleans and lets her live her life. He shows great sadness at her leaving though.
In Moon Over Bourbon Street, after a month, he and Genevieve have become lovers. Elijah isn't happy with this relationship. He asks Klaus if he has forgotten that Genevieve tortured their sister and as a result she is now gone forever. Klaus responds that Rebekah harbored the desire to leave for quite some time. Elijah tells him that he should stop his ridiculous behavior and channel it into some action. He wanted to become king and now he must accept the responsibilities that come with that. Klaus clearly isn't interested. Elijah wonders what will become of his daughter if it so easy for him to abandon his home. Klaus is not happy with this remark. Elijah asks him if he has forgotten what it was like to live under the threat of violence. They must work together and make the city whole again. Klaus tells him that maybe the city is too broken to mend. Elijah tells him that if he will not do anything, Elijah will do it in stead.
Elijah wants to make a peace treaty involving all the factions. Klaus gives him some advice, Elijah should start with the werewolves if he wants peace. And if bringing everyone at the table is the problem, then he should just remove the table and throw a party. Elijah agrees and invites all the factions to a party at their home. Klaus attends to the party. He takes a specific interest in Jackson. He tells Jackson that his mother made a moonlight ring for his biological father that prevented him from turning. He could then access all the power he had as a wolf in his human form. Klaus tells Jackson he wants to give the werewolves rings like this so that they are strong enough to protect his unborn daughter. Vampires aren't loyal, werewolves however are. Family is very important to them and he wants the safety of that loyalty for his unborn daughter. Later Elijah wants Klaus to sign the peace treaty. Klaus however thinks the treaty will fail. At the end of the episode he's smiling as he looks at a painting he just made, the city of New Orleans with a full moon.
In The Big Uneasy, Klaus is seen painting Genevieve in the nude and then complaining to Elijah about the racket happening outside. Klaus is also trying to form alliances with the werewolves and the witches. He also asks Oliver to find Cary, which he does, and he asks Cary what stone the ring housed and to find out what it was. He is confronted by Genevieve about Esther's grimoire and he tells her that she doesn't have leverage over him. He comes to the witches' ceremony and presents Davina with a gift, for which she does refuse, and he apologizes for what he did to Tim, and she later accepts. She sees that it is a page from Esther's grimoire about how to make daylight rings. He then shows Genevieve the hands of the witch he cut off and she then tells him she was thinking about taking the hex off Kieran, but she changes her mind. He and Elijah also get into a fight, which ends with Klaus looking troubled. He later tells Cami that Genevieve won't take off the hex and that he will kill Marcel if he sees him.
In An Unblinking Death, he is seen looking for his mother's grimoire, but Elijah has put in a place where he can't find it since he knows about the alliances Klaus is trying to put together. He gets a call from Marcel about Kieran, and he goes over to the church. He then turns Kieran for Camille, but unfortunately he has to kill because the hex and the vampire lust took control and he has to save Camille, then he takes Camille to her home and calls Marcel to accompany her. He allows Marcel to come back for Kieran's funeral. He is then also given the grimoire by Elijah.
In A Closer Walk With Thee, Klaus is having a nightmare of being at Kieran's funeral and sees his daughter, unfortunately he is staked through the chest by Mikael. He wakes up and he later goes to Rousseau's. He is drinking a lot and tells Elijah that he has been dreaming about their father. Elijah is shocked and tells him that he has been doing the same thing. Klaus makes a call to Bonnie and she tells him the Other Side is falling apart. He attends the funeral with Elijah and Hayley as well. After Hayley briefly dies, he wants the baby to get out of her, but Genevieve tells him it will kill Hayley. He later confronts Marcel and he expects nothing less from him when Marcel tells him he'll fight till he's dead.
In The Battle of New Orleans, Klaus shows Genevieve the spell required to create the moonlight rings and tells her of the changes he wants made to them. He then promises her that, in exchange for her allegiance, he will give her his mother's spell book and protect her from all her enemies. When Marcel snatches Jackson and Oliver as they arrived with the black kyanite stones needed for the spell, Klaus deduces from Genevieve's inability to locate them that Marcel had a cloaking spell around him. Klaus threatens Davina (who cast the spell for Marcel) by bitting Josh into telling him where Marcel is. He heads to the warehouse where he and Elijah find Jackson bound to a chair tied to explosives.
A timer makes them go off as Marcel's revenge for Thierry's death but all three make it out alive. They return to the compound where Genevieve tells Klaus that she needs something to bind the spell, ideally another wolf who can control his transformation and Klaus offers his blood. Klaus also reveals that he had a Plan B: he had asked Francesca Correa to find black kyanite for them as a backup. As Genevieve performs the spell, Marcel and his vampires attack the compound. Marcel draws Klaus away and the two fight, while Elijah holds off the whole vampire army on his own. Klaus bites Marcel to kill him but at that moment, the werewolves call on the stones to prevent their transformation and drain Klaus of his strength. Marcel escapes and Genevieve later finds a weakened Klaus and tells him what she did: that the stones drew their power from him and that he would now be weak and in pain every time a werewolf drew on them to prevent their turn. She then knocks him out with magic. Klaus later wanders aimlessly through the streets of New Orleans until he hears Hayley's screams coming from St. Anne's Church. He realizing that Hayley and his child are in danger, Klaus screams up to the sky in anger.
In From a Cradle to a Grave, Klaus is first seen in a flashback with Hayley, in which she allows Klaus to feel the baby kick. In present time Klaus arrives at St. Anne's Church and tries to save Hayley and the baby from the witches, but in the process he gets pinned to the wall by magic. Klaus remains pinned to the wall as Hayley gives birth to his daughter. He watches in shock as Hayley bleeds to death after her throat is slit. Klaus shouts out in anger as the witches leave with the baby, he gets his neck snapped and he drops to the floor. Elijah finds a devastated Klaus with Hayley in his lap, and Klaus says to Elijah that Hayley is gone. Klaus heals Elijah of his werewolf bites, he explains what has happened and they leave to go save the baby.
While in the cemetery Klaus and Elijah have a heart to heart about Hayley, and they continue their search for the baby even though the witches have put up a spell to form an illusion so they can't locate the witches whereabouts. Hayley shows up at the cemetery in transition. Klaus explains that she died with the baby's blood in her system and now she is transitioning into a hybrid. Klaus, Hayley and Elijah find the witches as the sacrifice begins. In the battle to save the baby from the witches Klaus kills Abigail but it is Marcel who rescues the baby.
Klaus follows Marcel and heals him of his werewolf bite as he saved his daughter. Klaus is later seen backing up Hayley's decision to send their daughter away to keep her safe as New Orleans is too dangerous for the baby to stay, (for now). Klaus suggests they fake the baby's death to keep her safe. ]Camille visits Klaus believing the baby is dead and he tells her they can't be friends anymore as he doesn't want to ruin her. Klaus is seen talking to Elijah and tells him to take their families mourning public to keep up the ruse. Klaus then takes the baby to a deserted area where he meets Rebekah. Klaus gives an emotional farewell speech to his daughter before handing her to Rebekah. Klaus knows that Rebekah will keep his daughter safe and he tells her that he trusts her with his daughter's life. Before Rebekah leaves she tells him that she will make his daughter happy and she asks Klaus the baby's name. Klaus says her name is Hope. He cries as he watches Rebekah leave with Hope.
In Rebirth, Klaus is first seen setting up a canvas, preparing to paint. He accidentally rips it and angrily throws it, as soon as Elijah enters the room. Klaus talks about not doing anything and says he needs to spill blood. Elijah informs him that the remaining twelve moonlight rings have been found. Klaus then leaves, hunting for the rings. He pays Marcel a visit and asks him to assist him in taking the rings. Marcel agrees to help and brings Joe Dalton with him. Afterwards, Klaus returns to the compound to inform Elijah of their plan. Eventually him, Elijah and Hayley attack the Guerrera Mansion. Klaus kills a few werewolves and saves their blood, painting with it the next day at the family mansion. Klaus and Elijah begin destroying the stones used in the moonlight rings. However, they realize that a witch crafted them and only elements can destroy them. Later on, he talks to Hayley about being a hybrid. Hayley expresses sadness, but Klaus lightens her up by calling her a queen. He then comfortably squeezes Hayley's hand and tells her that they can defeat their enemies by working together.
In Alive and Kicking, Klaus tells Elijah about a witch hunt him and Hayley went on. Elijah scolds him for his actions, but Klaus says he's helping her. Later on, Klaus and Hayley head out to the Bayou in search of werewolves. Eventually they find Oliver and many other werewolves. Klaus threatens him, but Hayley stops him, not wanting a fight. Oliver then insults Hayley and Klaus slams him on the ground. Eventually, the two leave, Klaus saying he's going to find a witch and "educate" her. Klaus is seen at the cemetery talking to Cassie (who was being possessed by Esther at the time) and having tea with her. He comments on the tea, saying his mother made it and he disliked it. Klaus them proceeds to tell Cassie how terrible and insane Esther was. Cassie stops him and questions him, but Klaus is offended, as she called him by his full name. He threatens to kill the werewolves in the room and leaves enraged. When he returns to the compound he tells Elijah that he studied her and figured out it was their mother. He says he is going to kill her. However, Elijah reveals that Mikael, their father is still alive and Klaus asks who they should decide to kill first.
InEvery Mother's Son, Klaus and Elijah have dinner with their mother and brother. It is revealed that Esther was responsible for Klaus being weak in his human life.
InRed Door, Klaus reunites with Kol. Klaus and Mikael have a showdown. Klaus is almost killed in the struggle as Mikael stakes him with the white oak stake. Kol and Davina manage to make the white oak stake temporarily powerless. Cami manages to pull the stake out of Klaus while Mikael is distracted. Hayley and Marcel come to Klaus' aid and Mikael disappears.
InThe Map of Moments, Klaus is reunited with his daughter. He spends time with his family and he says he wishes it doesn't have to be like this. He later devises a plan with Rebekah and Kol to get rid of Esther.
In Sanctuary, Klaus and Hayley argue over whether to tell Jackson that Hope is still alive. To prevent Hayley from trying to stop him, he snaps Hayley's neck and he goes to kill Jackson. Klaus doesn't trust Jackson and he beats Jackson to a pulp but he is prevented from killing him by Hayley. Klaus decides to trust Hayley's judgment on Jackson and he agrees to let her tell Jackson about Hope.
In I Love You, Goodbye, Klaus arranges for Hope to come home. He attends the wedding where he plans on killing Jackson. He changes his mind and he introduces Hope to everyone. He then goes to a dying Kol's side.
"I never answered your question, if I’d ever thought about being human. Once. I was on a trek in the Andes, and a hummingbird flew up to me and just hovered there staring at me. Its tiny heart was pattering like a machine gun. And I thought, what a thing, you know, to have to work that hard every day just to stay alive, to be constantly on the verge of death, and how satisfying every day must be that it survived. And that was the only time I thought about being human."
While he was still an untriggered werewolf, Klaus had a complicated life. He was close with his half-sister Rebekah, whom he affectionately called "Bekah", and with his half-brothers Elijah and Henrik. Probably he also had a close relationship with the rest of his half-siblings; Finn and Kol. However, he had a bad relationship with his overbearing step-father Mikael who was harder on him than any of his siblings. He was a victim of his step-father's physical and verbal abuse since childhood. Klaus even admitted to Rebekah that Mikael frightened him which made him constantly seek his approval without ever finding it. His mother Esther often tried to calm Mikael when he became angry with Klaus, but she never tried to stop him from humiliating or from physically/mentally abusing her son. Also as an untriggered werewolf, Klaus had the aggressive behavior of one, but he could not act on it due to his mother making him wear a magical necklace, created to weaken his strength and thus leaving him vulnerable to Mikael's abuse. These following reasons led him to resent both his parents and possibly to be jealous of his siblings for having their approval. In the director's cut of the backdoor pilot of The Originals, Elijah pointed out that as a human, Klaus was so full of love and life, and that all he ever wanted was to be loved in return, especially by his step-father. This belief that no one loved him and that he was doomed to be alone forever was the main factor that changed Klaus's personality.
When Klaus was just in the early stages of being a hybrid, he slaughtered six villagers. Which afterwards, he was devastated and cried into Elijah's shoulder. After finding out that Mikael is not his father, he seems shocked and betrayed.
Klaus is continuously described as being cruel, sadistic, careless, paranoid, impulsive, emotional, short tempered, volatile, narcissistic, manipulative, jealous, obsessive and competitive. Unlike his half-brother Elijah, Klaus has little to no regard for human life in general, he has guilt and remorse for his actions, but he does not show it. Despite his negative traits, Klaus has shown to be very protective of his younger half-sister Rebekah, who stayed by his side for centuries, and he is not pure evil (he is just sadistic). Unbeknownst to any, Klaus was not the son of Mikael, but the son of a werewolf in another village which made Klaus both aggressive and angry. When he became a vampire, all these emotions were heightened and Klaus' temper became worse than ever. Years of humiliation and physically/mentally abuses. at Mikael's hands and Esther's indifference, coupled with her rejection of him as her son, led Klaus to kill his own mother in revenge and for betraying him. After this, Klaus shut off his humanity to any but his family, killing any who crossed his path. Vengeful and power-hungry, he will stop at nothing to achieve his ends and remove those who stand in his way. However, Klaus does not believe that death is a punishment as seen when he denies Katherine death, instead keeping her alive so that she will suffer for having betrayed him. He will also place usefulness before pleasure and keeps people alive when it suits his needs. He has also shown a penchant for working with witches which was mentioned by Katherine in Know Thy Enemy. Klaus also has a sense of honor and will not go back on his word although, like his half-brother Elijah, he will always look for loopholes in the deals he makes.
He has also shown a sadistic side notably when he deals with humans or vampires who have crossed him, such as Elena, Damon and Katherine. (His sadistic nature is often seen as psychotic). However, Klaus' hunger for power actually hides a deep fear of being alone which must stem from his step-father's treatment of him. He wants the hybrids so that he will not be the sole member of his race as Esther intended when she placed the curse on him. He also desires, beyond anything else, to be reunited with friends and family as shown by his desire to have Stefan, his one-time friend, and his family back at his side. According to Elijah, Klaus also uses his cruelty to hide his fear of being alone. He has shown to have a softer side when he is around Caroline, or a member of his family, but rarely shows it around other people. Caroline brings out Klaus' humanity. He also holds grudges against the people who try to kill him, or members of his family, and rarely lets it go. Klaus is self-preservation whenever he is in a situation where he could be killed permanently, he reveals information that keeps him from being killed, like when he told Elijah that he didn't bury their family at sea, or when he told Stefan and Damon he is the one who sired their bloodline.
Klaus rarely gets made a fool out of and also doesn't like to be made a fool out of either. He is rarely caught off guard. He is intelligent, calculating, thinks of contingencies, (Klaus admits he makes mistakes and learns from them as well), and he is always two steps ahead of his enemies. Klaus is not as forgiving as his half-brother Elijah; he rarely forgives people in general. Despite him being the world's most powerful immortal being, often pretends to be arrogant to mask his fear of being alone, he is not completely fearless. He is afraid of the White Oak Stake, because it is the only physical weapon that can permanently kill him. Klaus has a sarcastic sense of humor and he is also sarcastic even towards members of his own family. Despite his lust for power, Klaus still cares about the remaining members of his family. Despite being manipulative, he does not like being lied to or manipulated. He does not take being betrayed very well, especially if it is from a member of his family. He is not tolerant of people who disappoint him in general. He has very little tolerance for disloyalty. If any of his friends or family have try to kill him, or betrayed him to his enemies who wants him dead, Klaus disowns them and no longer see them as his friends or family; like Esther, Finn, Rebekah and Marcel. Klaus is ruthless and brutal towards his enemies, and he rarely shows any of his enemies mercy. Also if anyone tries to hurt or kill a member of his family, most of them will not live to regret it. Klaus has morals, but he is not as moral as Elijah, he can sometimes be ill-mannered.
Klaus can sometimes be cold, he is not above killing children, if they are a threat to him or his family, despite this Klaus dislikes people in general, who mistreat or abuse their children; due to how he was mistreated and abuse by his step-father, Mikael.
During his time in New Orleans, Klaus has grown to genuinely care about his unborn child, and was deeply hurt when Elijah and Hayley falsely accused him of using her to sire more hybrids. Although, he does still maintain a twisted sense of humor about his child as he once referred to his child as "that" when discussion how to keep it and Hayley safe from Marcel. Klaus is also shown to be more mellow as he was shown to genuinely regret daggering Elijah and went out of his way to show how sorry he was, even going as far as to spare Agnes for trying to kill his unborn child just so Elijah could keep his word. It is possible that being in his former home, with his family, has caused his humanity to show more. Klaus has also shown to have matured greatly as he no longer uses the White Oak Dagger to put down his maternal half-siblings when he disagrees with them like before but instead settles things in a civil and sometimes violent matter.
He does not like to be accused of something he didn't do, or something he was never planning to do in the first place.
As the baby's birth approached, Klaus became more and more protective of both her and Hayley. He even had a nursery built right next to Hayley's bedroom so she could be near her baby. His undying love for the child is evident as he willingly sent the child away from the chaos in New Orleans so that she could grow up properly in the loving arms of her aunt Rebekah.
Even if he is cruel, we can see he still has a part of humanity which is shown when he's about to cry when he sees his dead half-brother (Kol), when he admits his love for Caroline or when Hayley is pregnant of their child and he's fighting for her safety. Unlike Elijah, Klaus is far less calm, composed, and strategic in battle. Despite his temper, Klaus is shown to be very keen as he was able to figure out Hope would be sacrificed at the cemetery because it was where the Harvest and the Reaping took place as well as the location of the ancestral witches' burial place. Klaus does seem to care about Tyler to a degree. When he told Caroline he defeated Tyler, he left out the detail that Tyler tried to kill Hayley and his unborn child. This could be due to not wanting Caroline to hate Tyler, or possibly just wanted to keep his child's existence a secret as much as possible, as Klaus has made many enemies over the years. Klaus also did mention after Stefan watched knowingly as he walked into a trap by his hybrids, he wanted to kill Stefan but he fought the urge to and mentioned it took three days to finally lose the urge to kill Stefan, when he could have ended it in an instant by killing Stefan.
Klaus is shown to have developed strong paternal instincts since the birth of Hope. One such case is his belief a parent who trades their child for anything deserves a punishment worse than death. Klaus has also mellowed great deal a since season 1, so much so he, in an ironic twist of fate, restrained Elijah when he lost his temper when Finn threatened Rebekah (and unknowingly Hope) unlike before where he would just let the blood flow. Klaus' main concern is keeping his daughter safe now that she has returned home.
Klaus has also developed strong friendship instincts. One example was when he gave up an opportunity to kill Mikael when he threw Papa Tunde's Blade at Camille and chose to safe guard her life over killing Mikael.
Klaus is an attractive man. His height is 5'11. Klaus possesses curled dirty-blond hair and light blue eyes that contrasts with his pearl-white skin. As a vampire and a warrior (10th century), he is well-built. Klaus possesses a delicate and yet masculine face, possibly due to the fact that he was once a nobleman in the 15th century.
Klaus' clothing style is quite casual, usually seen wearing shirts, jeans and jackets, although he can also use a more classic and refined outfit if the situation requires it (ex: the ritual of the moonstone; the Original ball thrown by Esther). He uses accessories, such as leather bracelets or necklaces as seen in some scenes at the beginning of Season 3.
Powers and Abilities
As an Original Vampire, and later the Original Hybrid, this makes Klaus possibly the strongest of the Original Vampires. His Werewolf side has given him additional powers and abilities the others do not possess, making him among the most powerful supernatural beings in the world. though his maternal half-siblings and his step-father have been able to fight him on almost even terms, and he feared Mikael; while he had the White Oak Stake. His powers and abilities improve with the consumption of human or vampire blood, assuming his werewolf form or utilizing his lycanthropic enhancements and the full moon. In Live and Let Die, it is shown that Mikael is slightly stronger than Klaus, although it should be noted that he was still effected with werewolf venom and Klaus was not using his full powers and abilities.
Even before Klaus became the Original Hybrid, he was a master swordsman, even though he rarely uses a sword, due to his supernatural powers and abilities, Klaus' swordsman skills have not decreased. In Every Mother's Son, it has been hinted that Klaus' swordsman skills are superior to Mikael's.
Klaus has shown to be an expert fighter even when unarmed; When Marcel's army took him on, despite being overwhelmed to begin with, he was able to fight them, almost evenly and overpower most of them, through his fighting skills and Original Hybrid powers and abilities. In that single fight, he killed roughly twenty four non-original vampires single-handedly, showing his skills as a combatant even further. Klaus is far less calm, composed, and strategic in battle than Elijah. Due to his long existence, Klaus has seen countless battles and is very experienced in battle.
Elijah is Klaus' maternal older half-brother. As humans, they were close, engaging in friendly sword fights, however their relationship became strained due to both falling for the the same woman, Tatia. After transitioning into vampires, along with their sister, Rebekah, they made a pact to always stick by each other "Always and Forever". In 1492, their close relationship crumbled upon the arrival of the doppelgänger Katerina Petrova. Klaus wanted to use her blood to break the Hybrid Curse, but after her escape, Klaus was furious and blamed his half-brother. Although Elijah promised he would find her, their relationship never recovered as in 2010, Elijah planned to help the Salvatores and Elena Gilbert kill Klaus. After Klaus broke the curse, at Elijah's mercy, he revealed that he didn't kill their family and that their bodies were safe. Elijah saved his half-brother's life, however was neutralized in return. Their bitter relationship continued after Elijah was un-daggered by Damon Salvatore. However, the half-brothers became allies after their mother returned and were unsure of her intentions regarding their family. In the Season Three finale, Elijah bargained for his half-brother's body back and was clearly devastated by his "death". Throughout the trials and tribulations which threatened to rip their brotherly bond, they have recently begun mending their relationship and even though Klaus refused to grant Katherine freedom by Elijah's request, Elijah has stated he won't give up on finding Klaus' redemption.
Unfortunately, Klaus' relationship with Elijah takes a turn for the worst when Elijah chose to believe Tyler's lies over him, that he is (supposedly) aware that his child's blood can make hybrids, and he plans to use his child's blood once she is born to make an army of hybrids, to take over New Orleans, Elijah falsely accused him of only caring about his unborn child, so he could use her to sire more hybrids, Klaus became hurt/enraged by the accusation, he violently bit Elijah in retaliation, their relationship became damaged after this. Klaus eventually forgave Elijah, when he apologized to Klaus for his accusation. Despite the fact that their relationship is now repaired, Klaus is barely on speaking terms with Elijah.
Rebekah is Klaus' maternal younger half-sister. Out of all his half-siblings, he is closest to her, and very protective of her. Klaus cares very deeply for Rebekah, but he seems to have a lot difficulty showing her that it is true. They are loyal to each other. Before she left New Orleans, thus separating, they had never left each other's side and stood by one another no matter what happened. After Klaus was "supposedly" killed by Alaric in The Departed, Rebekah was heartbroken over losing her older half-brother whom she loved and never left her. When she finds out in the Season Four premiere that he was still alive, their relationship started to completely and totally fall apart when he chose to save Caroline over his own half-sister. Rebekah confronted him about how she never stopped loving him through everything. It was always her that was there for him when Finn, Kol and Elijah weren't. She then realized that he truly doesn't love her when he told her they are no longer family, and disowned her. But later in the season, Klaus saves her when Kol nearly kills her with a White Oak Stake. Even when she hates him, Klaus shows that he still cares and loves her regardless of what has happened between them. After Klaus is again the King of New Orleans, she begins to form her own army and so to defeat Klaus and Marcel, since she tired of always being used by them. Nevertheless, Rebekah has tried to protect the daughter of Klaus at all costs. When discovering that it was Rebekah whom brought their father to New Orleans, he decided to get revenge and wanted answers. She admitted that she wanted him dead as he robbed her of love and happiness. Klaus decided to exile her, telling her to leave New Orleans and never come back. Klaus decided to entrust the safety of her daughter to Rebekah, she returned to New Orleans to take Hope with her and care for her.
Kol is Klaus' maternal younger half-brother. Kol and Klaus both have a short temper. It is known that Klaus daggered Kol over a century ago. Kol and Klaus seem to argue every time they talk to each other, Kol even joked to Klaus about his dagger threats showing he was not over being daggered for a century. Even though he had been daggered for a century, he quickly got with times as he was seeing playing a video game perfectly. Klaus and Kol both like to drink together and have brotherly bond. Klaus cares deeply for Kol as he was rushing to his body when the Mystic Falls gang daggered Kol. Kol seems to ruin many of Klaus plans like finding the cure for vampirism, by killing Shane and the newly turned vampires. In Every Mother's Son Finn reveals to his brothers that Kol is alive, and Klaus expresses disbelief that Kol would have gone along with Esther, stating that the only thing Kol listens to is his ego, but Finn confirmed Kol's supposed loyalty, saying that their mother's proposition had brought even the wildest of Mikaelsons onto her side. Kol later switches loyalties over to Klaus and Elijah. Klaus and Kol have been seen getting along at time since then, and fighting at others. They seem to banter often and in good fun. Klaus was furious with Kol for hiding where he hid Rebekah, and threw him to hungry vampires in his anger. But Klaus forgave him, when Kol was cursed by Finn. After all, everything Kol has ever wanted was his family to care about him. This wish came true when Kol died because of the curse. Klaus was there on his side, together with Rebekah and Elijah. Before Kol died he wanted Davina to leave him alone, but his three siblings came and Klaus said that Kol can´t just flee from "Always and Forever" He died in their arms, as a part of the family.
Hope is Klaus' only daughter and child with Hayley. In the beginning Klaus wasn't happy with the arrival of his baby, then with time he started to change his mind and began to worry about her safety. He looked happy when Hayley told him that the baby would be a girl, then he began to fight for her protection against his enemies. Now he loves her more than anything and in order to protect her from the people that are trying to kill her, he and Hayley decided it was best to send her away. She was given to Rebekah, who would keep her safe. Klaus was reunited with Hope when her safety was compromised. Hope is now living at home with her parents. The supernatural community is now aware of her existence.
Klaus and Hayley first interacted in The Rager, when Hayley first visited Tyler in Mystic Falls, being the one who helped him break his Sire Bond. Klaus initially believed her to be a fling of Tyler's whilst in the Appalachians, however it was revealed she came to Mystic Falls in a deliberate attempt to have Klaus murder his hybrids, in exchange for information on her family. She succeeds and disappears, only to come back in Bring It On, where Klaus saves her from a vampire sent by Katherine to kill her. Klaus takes her back to his house, after talking a lot Klaus received a call form Rebekah, he tells Hayley that the vampire lurking around to kill her is dead. Even though she had to go, Klaus offers her to stay. She agrees and they end up having sex. Klaus tells Hayley he knows something about her family after noticing a special birthmark on her shoulder. Hayley ends up in New Orleans where she finds out that she is pregnant with Klaus' child. Not keen to the idea at first, Klaus has shown to care about his child in more than one occasion, fearing that someone might try to take her away from him. The relationship between Klaus and the mother of his child has evolved along the series, both coming to a mutual understanding, while Klaus also shows that he cares about her. After her encounter with Klaus' step-father Mikael on the other side and nearly killed by him along with her baby, Hayley is shown by Klaus their child's nursery after Hayley decides to move back to the compound. Klaus and Hayley share a moment in which Klaus asks her what Mikael has told her about him, Hayley tells him "Nothing true", which shows that they now have a good relationship. Klaus and Hayley are currently friends and they work together in order to keep their child safe.
Marcel is Klaus' best friend and former student. It's complicated, but they respect each other. There's definitely a history between them. It has been stated many times that Klaus loves Marcel like a son. Also, Marcel is very much in favor of embracing his true nature as a vampire and that’s something he learned from Klaus and something they certainly have in common. When Klaus returns to New Orleans after 100 years, he finds that Marcel has taken control of the city. Seeing that his former student has used everything he's taught him and achieved glory, Klaus wants what he has, forming a rivalry between the two. But Klaus still sees Marcel as his old friend. After Marcel attempted to bury Klaus, he surrendered New Orleans to him and despite their still unresolved differences, Klaus asked Marcel to rule side by side with him. After finding out that Marcel conspired with Rebekah to bring Mikael back in order to get Klaus to run from New Orleans and for him and Rebekah to be together, Marcel was banished from New Orleans. His relationship with Klaus is currently broken as Marcel lives in exile and tries to find a way to get New Orleans back under his rule. After he helped save Klaus's child from being sacrificed, Klaus gave him some blood to cure the werewolf bite and they returned to being allies once more.
Klaus and Caroline's relationship has slowly been coming together ever since he saved her life on her birthday in Our Town. Klaus later developed an unrequited romantic interest in Caroline and invited her to his family's ball. At the ball, they danced and talked together and she soon discovered a soft side to Klaus. When she returned home that night, she found a hand-drawn picture of her and a horse, from Klaus. As the series progressed, Klaus fell for her even more because in his eyes, she's too smart to be seduced by him, she's beautiful, strong and full of light.

Klaus seems to be a very talented artist. He has a landscape painting hanging in the Hermitage museum and sometimes gives his paintings away to others for fun.
Despite the fact that most people call Katherine with the Anglo version (Katherine) of her name, Klaus and Elijah, Rose, Trevor, and Nadia are the only ones who refer to or call her by her original name Katerina.
It is revealed in Growing Pains that Klaus' body survived the White Oak Stake because Alaric closed the coffin immediately after staking Klaus. For a fire to burn correctly, it needs access to oxygen. This is explained by Klaus "...When I assumed I'd be a pile of ash, but apparently fate and oxygen intervened..."
Caroline brings out Klaus' humanity. He thinks that Caroline is beautiful, strong, and full of light.
Klaus is the only original vampire to kill another Original Vampire, Mikael.
Klaus, Finn and Kol are the only Original Vampires with a known bloodline.
Klaus has the largest known bloodline than any other Original Vampire.
Despite being a hybrid who can transform into a werewolf at will, Klaus has not yet transformed into a werewolf on-screen.
Klaus is the third Original Vampire to be invited into the Gilbert House. Behind Elijah and Kol.
In Season 2, Klaus was possessing Alaric's body.
Klaus has been daggered a number of times, but due to his Werewolf side, he was unaffected by the silver White Oak Ash Daggers. He has only been neutralized once with the gold White Oak Ash Dagger Kol created specifically for Klaus:
Out of all of the Original Vampires, Klaus can be considered the most dangerous and tempered, as well as the most feared and hated Original Vampire, excluding Mikael as not everyone knows he is an Original Vampire, most believe he is an ancient vampire who hunts other vampires.
Klaus' status as Vampire King of New Orleans is now defunct, as, due to the werewolves' massacre, the vampire kingdom no longer exists.
Klaus's daughter Hope is the person he loves the most in the world.
Although Werewolf venom doesn't affect him like with his siblings it still does something to him as seen in Long Way Back From Hell when Genevieve gave him something with Rebekah's blood and with recently being bitten by werewolves he almost coughed it all up.
In Every Mother's Son it's revealed in a flashback that Esther gave him a necklace that weakened his untriggered werewolf strength and prevented him from getting enraged. She did this to prevent him from breaking his werewolf curse, though Klaus believes it was to hide her affair.
The one time that Klaus has actually been neutralized was not from a white ash dagger, but a unpowered white oak stake.
In Every Mother's son, Finn states that he expected cruelty from Klaus when discussing how he was left daggered for nine hundred years, this is indicates that Klaus became cruel and vicious within only a hundred years of being a vampire.
Klaus has killed both of his fathers.
He killed Mikael, his step-father, who he grew up believing was his true father, in TVD. However, Mikael has been resurrected by Davina to kill Klaus.
Klaus has also killed his true biological father, a werewolf named Ansel, in TO, because Ansel knew Hope was alive and Klaus could not risk Esther finding out from him that the baby was alive.
The Casanova - Katerina (a little) and, most recently, Caroline.
All Love is Unrequited - Caroline. Despite his attempts to woo her, and the fact that she knows he's in love with her, she is in love with Tyler and keeps refusing his advances. Still has chance to be averted, though is increasingly unlikely given the time he has left in Mystic Falls. See also Sympathy for the Devil .
And I Must Scream - Shared with family. However, instead of being daggered, Klaus must literally be chained and desiccated. When Alaric was turned into a vampire/vampire hunter, Klaus could do nothing to prevent Alaric from staking his desiccated body with the white oak stake .
Papa Wolf- Overprotective Dad- Klaus is very protective of his daughter and has no limits when it comes to Hope's safety and well being. He even killed his own father in order to protect his daughter after he found out about Hope still being alive. Klaus trusts nobody apart from himself when it comes to Hope and his love for her has no bounds.
(To Elijah) "Quite the hero, aren’t you? Yeah, I’ve heard that about you."
(To Stefan) "I heard about this one vampire, crazy bloke, always on and off the wagon for decades. When he was off, he was magnificent. 1917, he went into Monterrey and wiped out an entire migrant village. A true ripper. Sound familiar?"
(To Stefan) "There it is. You want to save your brother? How 'bout a decade long bender? And I have big plans for you when we leave this town."
(To Stefan about Katherine) "I've been around a long time, Stefan. I rarely get played for a fool."
(To Stefan about his Gift) "I could have compelled her to behave, but a real ripper enjoys the hunt."
(To Stefan): "I`m not mad, just curious. Rebekah seems to think you`re holding on to something. A piece of your old life. The thing is, she`s got flawless instincts, borderline supernatural. So I thought, I would check it out. See for myself what it is you`ve been hiding. Welcome back to Mystic Falls, Stefan.""
(To Bonnie) "You put a rather large kink in my plans, sweetheart. The whole point of breaking the curse and becoming a hybrid was to make more hybrids. I haven`t been able to do that. Now my bet is, it has something to do with the fact that you`re still breathing.."
(To Bonnie, Matt and Elena) "I`d like you all to meet my sister: Rebekah. Word of warning... she can be quite mean."
(To Bonnie) "If Bonnie`s successful, he`ll live through his transition. Go on, then. Go and fetch your grimoires and enchantments and what-not. I`ll hold on to Elena, for safe-keeping."
(To Elena) "It`s always nice to see a vampire in his true element. The species has become such a broody lot."
(To Stefan) "Now this is fascinating. I`ve never seen this before. The only thing stronger than your craving for blood is your love for this one girl."
(To Rebekah) "You know how much The Original Witch hated me. Do you honestly think I would do anything other than the opposite of what she says?"
(To Rebekah) "Rebekah, love. What`s this I hear about Mikael`s tragic run-in with a dagger?"
(To Stefan) "Seems the homecoming queens still walks among the living, which leads me to Rebekah isn't here, where is she?"
(To Elena) "I`ll get straight to the point, love. People have been after me for a thousand year and I`m always one step ahead, so whatever it is you`re trying. Go for it, give it your best shot. You won`t succeed."
(To Stefan) "Thank you my friend. You no longer have to do as I say so. You`re free."
(To Rebekah) "Rebekah, where are you? Daddy`s dead. It`s time for a family reunion."
(To Damon) "You people seem to respond best to violence."
(To Tyler) "You people seem to respond best to violence."
(To Tyler) "Human life is just a means to an end. Our means, to our end."
(To Rebekah's dead body) "Here we are, Rebekah. Home sweet home. Only took a thousand years. And to think, I was counting on you being here with me. But that's all ruined now, isn't it? I'm so sorry, sister. We'll meet again one day."
(To Caroline) "Do you really think that low of me?."
(To Caroline)"And I could let you, die, if that's what you want, if you really believe your existence has no meaning. I thought about it myself once or twice over the centuries, truth be told. But I'll let you in on a little secret, there's a whole world out there waiting for you, great cities and art and music, genuine beauty, and you can have all of it, you can have a thousand more birthdays. All you have to do is ask."
(To Damon)"Crazy or not. That kind of love never dies."
(To Stefan): "So, the fate of the entire vampire race depends on you finding a stake? And to get it we need you to pass out. Which means that I feel totally justified doing this."[breaks Alaric`s neck] ""There sleeping like a baby""
(To Stefan): "That’s a little gratuitous, don’t you think, Stefan? I would have been more gentle.""
(To Caroline): "I don't have to prove anything, love. I am the alpha male. Come on. One dance. I won't bite."
(To Caroline): "You should be nicer to me. I'm leaving town tomorrow. I'd invite you to come with me, but we both know you're not ready to accept my offer. Perhaps one day, in a year or even a century, you'll turn up at my door and let me show you what the world has to offer."
(To Caroline): "You mark my words. Small-town boy, small-town life, it won't be enough for you."
(To Esther) "Your trap failed Mother. I still live and I will go on living and should your beloved spirits try to preserve you again I dare you to come after me. I will build an army so big no one will ever touch me. My survival will haunt you for eternity. You will never destroy me!"
(To Jeremy) "Well, for starters, young Jeremy here could show some manners and invite me inside."
(To Stefan and Damon) ""Hmm..poor lad. Loses one questionable father figure only to be replaced by the likes of the two of you."
(To Damon) "Oh, I know all about my mother’s invulnerable little creation and that’s why I’m here. I’m leaving town, just need to pick up a few road trip necessities. Spare tire, flashlight, Doppelgänger."
(To Stefan and Damon) "Just so we are clear. The sun sets in about eight hours. If we don’t succeed before then, Elena will be dead, I’ll be gone, and the rest of you will be left to fend for yourselves."
(To Stefan, Damon, and Bonnie) "Before we all walk through these doors, let’s get on the same page, shall we? I was the one who created your vampire bloodline, therefore I am responsible for your lives and Tyler’s life, Caroline’s life, and of course, Abby’s life, should anything go wrong."
(To Damon) "I’m not lying. But go ahead, call my bluff, let the teacher kill me. You’ll all be dead soon thereafter."
(To Caroline): "It's okay, it's okay, it's me, you're safe. We'll go save Elena, you go straight home, you stay inside. Do you understand? Do you understand me?."
(To Elena) "You know Stefan blames me for trying to tear him from his brother, but I think we both know who really came between them. You. That’s why you won’t choose. You know once you pick a Salvatore, you’ll destroy their bond."
(To Elena) "Consider this me doing you a favor. Once you’re dead, you won’t have to choose. No broken hearts. Their family stays intact. But just between us girls, who would you have picked?"
(To Tyler) "You went off to the Appalachians to break my sire bond. There you met a pack of werewolves, among them was a girl. She was gorgeous with the same animal instincts as you. Emotions ran high and ambitions ran low. In a moment of weakness the thick sexual tension became something much more real. And Caroline has no idea."
(To Rebekah) "I mean it’s pathetic really, isn’t it? How she continues to hand her heart to any man who shows her a hint of affection. You think she would have learned by now from the endless cycle of disappointment and deception."
(To Caroline) "I never answered your question; if I ever thought about being human. Once, I was on a trek in the Andes, and a hummingbird flew up to me. It just hovered there, staring at me, its tiny heart was pattering like a machine gun. And I thought, what a thing, you know, to have to work that hard every day just to stay alive. To be constantly on the verge of death and how satisfying every day must be that it survived. And that was the only time I thought about being human."
(To Stefan) ""Loneliness Stefan, that's why you and I memorialize our dead. There's the briefest of moments where we hold their life in our hands and then we rip it away and we're left with nothing. So gathering other peoples letters or writing their names on a wall is a reminder that we are left infinitely and utterly alone.""
(To Damon) "Twelve... that's a number. That's how many of my hybrids I slaughtered with my sword. Tree. That's how many days it took me to quell the urge to kill your brother, after he knowingly watched as I walked into a death trap. One that's the number of purposes you serve."
(To Jeremy) "You really think I care for an instant about my bloody hybrids. I want the cure so I could destroy it, I would have killed you all the second we dug it up. But now I'm just going to watch you burn instead.'"
(To Tyler) ""See, now I think you’re just telling me what I want to hear. I mean, you did call me pathetic earlier. And wouldn’t it be more pathetic of me to help now knowing that, hours ago, you announced your plan to kill me in a manner of which you’re still debating because you want it to have a certain amount of flair? Just asking."
(To Elijah) "I gave you that opportunity. And you sided against me. So if I run, it'll be to chase her. And as your only living brother, I will make it my cause that you never know a moment of happiness."
(To Rebekah) "You can stand idly by as poor April takes her final breath. You can ask, "Why does this always happen to innocent people? Where do the spirits go? Was there anything I could have done?" That is what it means to be human, sister. You give humanity too much credit."
(To Tyler) "Was it worth it?. To see her smile?. To make her dream night come true?. Was it worth it?. In the shared interest of giving Caroline the night of her dreams, I'm going to allow you five seconds before I rip the heart out of your chest. 5, 4, 3."
(Call phone to Caroline) "Caroline, I’m standing in one of my favorite places in the world surrounded by food, music, art, culture, and all I could think about is how much I want to show it to you. Maybe one day you’ll let me."
(To Caroline) " Me... As soon as we're done here, I'm gonna walk away and I'm never coming back. You'll never again have to look me in the eye and cover our connection with hostility and revulsion. You’ll never have to loath the darkest parts of yourself that care for me in spite of all I’ve done. I will be gone and you’ll be free. I just want you to be honest with me."
(To Camille about Marcel) "Abnormal psychology, well, perhaps you could help me diagnose my friend over here. He's been a little bit depressed. Can't get his mind of a girl. He tells me she's a queen fit for a king. I think he should cut his losses and move on. What's your professional opinion?. "
(To Hayley about Marcel) " I made Marcel everything that he is, I treated him like a son, and when my father chased me and my family from New Orleans a hundred years ago, we believed Marcel was killed. We each mourned him our own way. Yet when I returned, I found not only had he survived, he had thrived. "
(To Hayley about Marcel) " Now he is living in our home, he is sleeping in our beds. The letter "M" he stamps everywhere, i'ts not for "Marcel", it's for Mikaelson... I want it all back, and if I have to push him out to get it, then that's exactly what I'll do. "
(To Hayley) "Okay. Well, firstly, Marcel is not my mortal enemy—he is my friend, albeit one who is unaware that I'm trying to sabotage his hold over the supernatural community of the French Quarter, but a friend nonetheless. And secondly, I daggered Elijah in order to gain Marcel's trust. If I had known he would place my brother in the hands of a particularly nasty teenaged witch, I certainly would have weighed my options a bit differently. And thirdly, sister, please."
(To Hayley) "Okay. Well, firstly, Marcel is not my mortal enemy—he is my friend, albeit one who is unaware that I'm trying to sabotage his hold over the supernatural community of the French Quarter, but a friend nonetheless. And secondly, I daggered Elijah in order to gain Marcel's trust. If I had known he would place my brother in the hands of a particularly nasty teenaged witch, I certainly would have weighed my options a bit differently. And thirdly, sister, please."
(To Marcel) " Still... You don't want the witches to get too bold, given that a witch's tip about a werewolf in town led to the disappearance of your nightwalkers. I'm sure you've considered the possibility that it could've been a trap. "
(To Davina) " If he remembers seeing you, he might come looking. If the witches learn of him, if they know you have a weakness, then poor Tim might end up as leverage in an awful scheme to control you. Again. "
(To Sophie) " We had a deal! You protect my unborn child, I dismantle Marcel's army. And whilst I've been busy fulfilling my part of the bargain, you allowed Hayley to be attacked and almost killed by a gaggle of lunatic witches. "
(To Agnes) " Enough! Please, enough! I don't care about witch politics. I don't care about your ridiculous little Harvest ritual. What I care about is this trinket... Undo its curse, or I'll show you things worse than death! "
(To Elijah) " You tend to give your word at the most inopportune times, brother. We've been doing things your way all day. Come on! Just one little snap and it's "Toodle-loo, Agnes." She deserves it! "
(To Elijah) " He was loyal in the beginning, but he grew insubordinate, turned my other hybrids against me. I couldn't have that, so I massacred the lot of them. Tyler ran like a coward before I could finish him off. "
(To Tyler) " Death offers more peace than you deserve. It's better to let you live. And each morning, you will wake knowing your wretched existence continues only by my will... Now go, and live the rest of your days knowing that you are nothing to me. "
(To Elijah) " And, of course, you assume it's true. I mean, why else would I show interest in my own flesh and blood? A heartbroken little crybaby points his finger at me, and my own brother falls in line, eager to believe it! How quickly you believe the worst, especially when it comes from her. "
(To Elijah) " My big brother, so, you doubt my intentions? Well, I can't say I'm surprised, standing next to the noble Elijah, how can I be anything but the lesser brother? A liar, a manipulator, a bastard. "
(To Rebekah) " Elijah and I had a bit of a row. Haha, Hayley's conspired to turn him against me. You know our brother was never one to resist a pretty face! So, one thing led to another, and I bit him, left them both stranded in the swamp. "
(To Rebekah) " Perhaps we will. After all, you know I'm capable of forgiving those who disappoint me! As soon as they've seen the error of their ways, and suffered for them. You'd do well to remember that. "
(To Rebekah) "Poppycock! I would never bite you. Elijah made some very offensive accusations about my intentions towards my child. He deserves a day or two of discomfort. Besides, you know my preferred method of punishment for your indiscretions is the dagger. "
(To Elijah and Rebekah) " Is that so? What have I done lately, other than cooperate? I bow down to you, brother, to make up for daggering you. For the greater good of our plan to reclaim our home. Looked the other way, sister. While you repeat the same cycle with Marcel, falling again for a man you shouldn't be with, while he controls the empire that we built! That he took! Now, I make no excuses for past sins. But in the one moment when you two could have chosen to stand by me - to believe in me - to believe my intentions for my own child were pure. You chose to stand against me, to side with my enemies. I wanted our home back. Now I have it. So I'm going to live there. And the two of you... you can stay here together... and rot. "
(To Hayley) " Because, Hayley, that child you carry is the only thing on this earth that matters to me. Now you can fight me on this, but you will lose. As will anyone else who tries to stop you getting in this car. "
" Let us begin with a toast to our shared gift: immortality. After a thousand years, one might expect life to be less keenly felt. For its beauties and its sorrows to diminuish with time. But as vampires, we feel more deeply than humans could possibly imagine. "
(To Camille) "And so then I bit Elijah and left him in the bayou with my hybrid venom in his veins. Serves him right for making such vile accusations against me. And then... Are you taking this down? "
(To Camille) " I mean, to be clear, I only compelled you to give him a chance. Anything you felt for him was quite real... and for the record, the level of awkwardness we're all currently experiencing is entirely genuine. "
(To Marcel) " Thierry was never disloyal to you, I set him up in an attempt to locate my brother. He's your friend, and consequently he can return to the compound at your discretion. Cami's part you just learnt, and then there's young Joshua. I've been compelling him from the beginning, although I suspect you already knew that as he was the one who led me into your trap. "
(To Marcel) " Yes, about that... Turns out your little witch is quite the actress. She made a deal with Elijah while he was in captivity, tricked you into letting her stay put in exchange for some spells from our mother's grimoire. "
(To Marcel) " I was beginning to worry about you. I don't think I could've taken any more of this differential nonsense. I mean clearly I underestimated the faction, that won't happen again, but tell me: Now that we've arrived to this point, now that they have come into our home, visited this upon our people... How would you council me to respond? "
(To Marcel) " To our united front! This act of yours, the imitation of friendship. Don't get me wrong, you played the part well enough, I should know, having played it myself. There was a time when the affinity between us was quite real. "
(To Marcel) " Fair enough. Then you should probably know the whole story. My decision was not entirely my own. If I didn't agree to usurp your power, the witches swore to kill my unborn child. But at first the promise of an offspring meant little to me. Then I recalled my father; how he held me in contempt from the moment I was born. As yours did with you. I will not do to my child what was done to me. To us. "
(To Marcel) " his community that you've built - you have their respect. Their love. I could rule them but I cannot win them, not without you. So rule with me. Side by side as equals. Friends. Brothers. "
(To Hayley) " Not for long, love. I mean, this so-called family of yours, they haven't done you much good, have they? You said it yourself: they abandoned you and left you on your own. Now it's simply your turn to do the same. "
(To Kieran) " You see, I recently ordered the slaughter of a group of vagabonds out in the bayou. Turns out, I may have been too hasty. Thing is, if the vampires find out I'm protecting them, it won't sit well. "
(To Camille) " Knowing what you do about this world will only get you killed, and I cannot allow that. Leave New Orleans. Forget everything you've learned here today. Forget me. You have no reason to stay. "
(ToElijah) " That child, to whom you refer to so affectionately, is the most powerful witch in New Orleans. If she's fled, what's to stop her from destroying us? In fact, destroying all we've worked for? No, if she's not a friend to this family, then she is our enemy. "
(ToJosh) " You're lying. In fact Marcel and I were just chatting about your failed double agent status, and we've surmised that you're likely still in town and in the company of a friend – a young, angry witch. "
(ToJosh) " Are you really going to leave Davina's fiddler soul mate, Timothy alone with me? Oh, Josh. What would she think of that? I assure you I just wanna talk to her. Tim and I will be at the compound. I really do hope she comes home soon. "
(ToElijah and Marcel) " Oh, come on. The stench of your judgment is overwhelming. Need I remind you that Davina just bested the lot of us? I did what had to be done. Don't worry, Elijah. I remain as redeemable as ever. "
(ToKieran) " I asked Father Kieran to give them shelter. He suffers from an incessant desire to do good. But now I need you to be useful. Marcel and Davina have disappeared. I assume from the stupefied look on your face they haven't sought refuge in your attic. "
(ToHayley) " They're not your werewolves. They're my clan. From very far back. They've fallen upon hard times, and their plight has brought out the philanthropist in me. What can I say? Must be Elijah's influence. "
(ToMarcel) " I'm sorry. You may think I know nothing of your grief, but you are wrong. In the days after I fled this city, I thought you were dead. It was years before I could speak your name, so keenly did I feel that loss. I'm sorry. I'm sorry. "
(ToRebekah) " This whole thing was doomed from the start, you know? Yes, we saved the city, and I'm not complaining about the witches losing their power, but this did not go down the way I thought it would. You surprised me, though. You were quite resourceful today. "
(ToElijah) " And, lucky for you, my brother always keeps his word. You two are from the guerrera crime family, a brutish pack of thieves and killers, and that's nothing compared to what you become on a full moon, is it? "
(ToMarcel) " Dearest brethren, your attention, please. No doubt, you're all surprised to see Thierry Vanchure, who's supposed to be rotting in the garden for the crime of killing one of our own, and I personally decided to issue him with a pardon. I hope you'll all welcome home Thierry. "
(ToMarcel) " Well, as much as I might like to, I have pressing responsibilities here. (addresses the crowd of vampires) Now, as you all know, the witch Davina is no longer with us. Without Davina, we can no longer monitor the activity of our witch neighbors. However, since their harvest failed, their magic will soon be gone forever. Until then, I say we keep them on their toes. Diego, I wonder if you might lead a rousting in the cauldron. "
(ToDiego) " Marcel has run off like a scared child. You lot are left with me. Now, who of you will fight to defend our home?... Not a single one of you will stand with me, so afraid are you of this new threat? You should know better. I'll handle this myself. "
(ToElijah) " Now that you are here, perhaps you could help settle an argument. You see, you've traded a war abroad for one here in the quarter. Some rogue witch wants a piece of the city we built, and Elijah, for reasons beyond my comprehension, insists that negotiation is our best recourse. "
(ToElijah) " On the topic of your failed comprehension, you neglect, as a soldier, Marcel has seen not only how small the world has become and how fast news can travel, but also the very horrors of war itself. Surely, Marcel would agree with me. "
(ToPapa Tunde) " Oh, in fact, I made it a point to learn all about your power. I noticed how you're almost always near those twin sons of yours, how they bear your distinctive Mark. Got me to thinking. "
(ToCamille) " I can see why you hate me. Truth be told, I have done some dreadful things. But the lies your uncle told were meant to protect you. He is a good man with a loyal heart. And he is your family. As for these witches, their attack on Kieran should be proof enough they are the enemy. In that we are united. "
(ToCamille) " Not remotely. But I can't attempt to use my compulsion to counter Bastianna's curse if the good Father has vervain in his system. Thus, we bleed him out. I never said this would be pleasent. "
" Witches of the French Quarter! I have with me Monique Deveraux. What a shame it would be were I forced to sent her back to the death she's just escaped! Should you wish to prevent this, bring me the witch Bastianna! "
(ToMarcel) " Spare me the hypocrisy of your moral code. It didn't stop you from killing Monique's mother. Bastianna! I know you're close. The stench of witches hangs in the air. Mark my words! I will end this girl with the very blade you meant for me. "
(To Elijah) " It's been months! I've adhered to our plan sit and do nothing, sell our grief, and now my child is safely away, and another full moon is upon us, another night of pathetic weakness as the moonlight rings steal my strength. The inertia is killing me. I need to act. I... I need... I need to spill blood. "
(To Elijah) " This was my fault, all of it. If had just accepted Hayley's pregnancy instead of... playing king. I should have listened to you. Instead, my greed and my envy robbed me of my daughter. My actions... led to the release of a weapon that can kill not just me but you. "
(To hayley) " You know, over the years, I've had my share of friends, enemies, lovers, losses, and triumphs. With time, they all begin to run together, but you will find the real moments are vibrant. The rest just fades away. Your pain will fade. "
