In Season Six, Liv still attended Whitmore College and had developed a romantic relationship in Tyler Lockwood. She carefully watched over Tyler, doing everything to make sure his werewolf gene doesn't trigger. In Fade Into You, Liv and Luke are reunited with their long-lost sister Jo and they reveal that, as the twin children of the Gemini Coven's leader, they must merge their powers on their twenty-second birthday and the stronger of the two will survive more powerful than ever while the weaker will die. In the season 6 finale, Liv was killed by Tyler with her permission and request so that he could trigger his werewolf gene in order to heal his wounds caused by Kai.
When Kai realized that Liv and Luke were a challenge to his future leadership, he attempted to kill them, killing his other siblings and stabbing Jo in the process. Jo cloaked the twins and tricked Kai by relinquishing her magic, allowing the coven to banish him to a Prison World. After this, Liv and Luke were raised knowing that one day they would have to "merge" to see who would be the stronger witch to one day lead their coven.
The twins were taught magic from a very young age, including mastering a simple locator spell in third grade. They also used to play hide-and-seek, and figured out a way to cheat by using a spell to see through one another's eyes.
In Total Eclipse of the Heart, Liv is first seen in class while she is playing with a pen. She is inexperienced in witchcraft and tries to avoid people. When Bonnie is forced to find a witch to save Jeremy, she goes to her and begs for her help and finally she agrees to help her. Bonnie tutors her how to do a locator spell and says that she could teach her to control her magic. She almost gives up when she accidentally breaks the lamp, but she finally manages to perform this spell.
In Gone Girl, Liv helps Bonnie and Jeremy do a locator spell to find Elena. She flirts with Jeremy much to Bonnie's distress and she visualizes Elena Gilbert in her head, asking if she spends a lot of time in churches.
In While You Were Sleeping, Liv sealed Elena inside a building so she can't harm anyone. As Elena's hallucinations progress, she stabs Liv and tells her to remove the seal or otherwise she will die and won't get vampire blood to heal herself. It is revealed that she is already a talented witch, who is aware that Bonnie is the Anchor to the Other Side and is just using her. As Luke, who is her brother, appears in her room, he tells her that their own agenda may be compromised, possibly due to the activities of the Travelers.
In Rescue Me, Liv has a conversation with Jeremy at the Grill, Jeremy asks her what’s going on and Liv answers that there’s been rumors going around in witch covens that the Travelers are up to something huge. Jeremy is confused, as he believed that Travelers were witches and Liv tells him that they’re more like the ugly stepsister. She says that Travelers hate anyone that draws magic from Nature because witches were said to have cursed the land against them and now they’re on the move and are headed to Mystic Falls. Jeremy asks why and Liv answers, “Your sister. It turns out Elena's friends are right. The world actually does revolve around her. So if you want to keep her safe, you're going to have to help me figure out what the travelers are up to.” Then Liv’s phone beeps and it is revealed to her that Hazel – a witch in her coven which was hiding Silas' last doppelgänger – is dead via a text from her brother. Jeremy asks the witch if everything is alright and she answers that it will be. She then gets up to leave but is stopped by Tyler, who tells her that it’s rude to leave Jeremy hanging even for a newbie witch. Liv then flings Tyler across the room with her magical powers and comments that she’s not a newbie in the witch-business before leaving. Later, Liv arrives at the school and ambushes Elena, throwing her against a wall telekinetically and sent wooden debris pinning her to the wall by her biceps, holding Elena there like glue. Liv apologizes and says that her coven did everything in its power to protect her, but she’s too dangerous now – hinting that she believes Tom is already dead, thus rendering Elena and Stefan’s blood prone to the Travelers finally. Elena tells her that she has no idea what she is talking about and Liv answers that she never will before lunging to finish her off with a piece of wood.
Liv is stopped in the nick of time by Damon, who knocks her unconscious. When she awakens, she is tortured by Damon who wants to know what she was doing trying to kill Elena. Liv is gagged and Damon tells her that he’s going to remove it and if he hears her mutter any spells, he’ll kill her himself. He does ungag her, but she just looks up at him and he continues to torture her. Elena demands that he stop but Damon reminds her that they’ve broken up and she can’t tell him what to do anymore – this leads to an argument between the vampire ex-couple, which makes Liv feel awkward and she blurts out that they should just kill her. Damon tells her that it is a tempting offer, but he won’t until she starts talking. Liv tells them that Elena’s the last female doppelgänger and that after that night, Stefan might be the last male one and once that happens, the Travelers will come for Elena to use her and the witches can’t let that happen. Damon and Elena begin to argue once more and are interrupted by Jeremy walking into the room and scolding them and telling them that if they kill Liv they’ll have to kill him too. Jeremy tells Damon to go on and that it wouldn’t be the first time he’s killed him. Jeremy then promises Elena that if they let Liv go, he will not let anything happen to her. Elena tells Damon that he trusts Jeremy and the two vampires leave the witch and the Hunter alone at which time Jeremy unties Liv. Later, Liv meets up with her twin, Luke, in the parking lot and asks him where he was angrily, which Luke answers that the two of them may not even be here if she’d killed Elena – implying that there’s much more to Elena and Stefan’s doppelgänger-ness than meets the eye. Jeremy tells them that plan C’s that they’ll protect Elena and he’ll stop the Travelers. Liv tells his brother not to fear the idea because he’s got Hunter powers and will see the Travelers coming before they do and then she asks Jeremy what the catch is to which Jeremy answers that he needs help, Tyler and Matt show up and Jeremy tells the twins that they’re part of the package – take it or leave it.
In Resident Evil, Liv has Matt and Tyler stab themselves with the knife that kills Passengers to ensure they aren't hosting any. They do so and they are all in the clear. She proceeds to tell them about what she knows about the Travelers and how they must repeat this process to about everyone else in Mystic Falls and that her coven has been tracking the Travelers. She tells them that they are taking over towns one by one by putting Passengers in the townsfolk. Later on, she calls Jeremy to get back to work and sees him talking with Bonnie at the front door. Bonnie questions their activities but Liv ensures it is not what it looks like and is merely helping him with Math. Bonnie reminds them about how Liv had tried lied to them and even tried to kill Elena. Bonnie wants to know what is going on but Jeremy doesn't want to tell her. Liv rolls her eyes and reminds Jeremy that she's not going to break her rule again about not letting anyone in on what they're doing. Tyler comes in while on the phone with Matt and hangs up after they talk about who the Travelers might want to possess.
In Man on Fire, Liv is forced by Enzo to use her magic to subdue Stefan and Elena at the bar where she works. If she didn't, Enzo would kill her brother whom he had kidnapped. However, Bonnie realized that Enzo's threats were actually beneficial to Liv because if Stefan or Elena died, the Travelers wouldn't be able to use them. Bonnie also tries to ask Liv's help in saving The Other Side which was falling apart due to Markos's return. Enzo almost kills Liv after turning off his humanity but Stefan saves her by feeding her his blood. Later on, Liv reveals to Bonnie that she doesn't know how to save the Other Side and that she should say her goodbyes while she still has the chance.
In Promised Land, she is waiting for her brother at a diner, having already ordered them waffles as a "last meal." She then scolds Luke for allowing the Travelers to take the doppelgängers before their coven also scolds Luke by causing him extreme pain from some remote location. The twins then team up to take out Stefan and Elena and stop the spell to end all magic. Using telekinesis, Liv crashes the truck containing the doppelgängers, killing the Traveler Maria before turning her power on Elena while Luke turned his on Stefan. Before they could finish their task, the Traveler's spell caught up with them and they lost their magic, allowing Elena and Stefan to escape.
In Home, the twins are driving out of town, with Liv making constant criticisms against Luke for how slow he was driving, making a snarky comment about how they should drive away from the people they tried to murder faster. Before the argument could progress, Elena appeared on the road before them, with Caroline standing in their way from behind. Elena tries to get them to help with a resurrection spell, but even after stating how sorry she was for what had happened, she and Luke refused. To give him some motivation, Caroline snapped Luke's neck, sending him to the Other Side and giving Liv some incentive for the spell. She is seen later in the same crypt where Alaric was turned into an Enhanced Original preparing for the resurrection spell while crying for her brother. Unable to see him because of his status as a ghost, Luke was behind her, offering her support and telling her she could do this. At 7:00 on the dot, Liv began the spell. After all the Travelers passed through Bonnie, the spell began in earnest with Luke being the first to pass through to help his sister, as the strain of the spell was slowly killing her. She refused as she had promised she would help the others and continued with the spell. With each person passing back to this side of the Veil, Liv grew weaker with Luke eventually taking matters into his own hands and forcibly stopping the spell, trapping Damon on the Other Side. When Elena went to see what had happened with the spell, she discovered that Luke and Liv had fled the crypt.
In I'll Remember, Liv is attending Alaric's Occult Studies class, chuckling at the irony of talking about resurrection with one of the very people she resurrected. Tyler shows up late to class and takes a seat next to Liv, who uses her magic to turn his book to the page the rest of the class is on. Later, she is seen drinking among the other students during the pre-football game party in the parking lot next to the stadium. After she hears about Tyler attacking her brother, she goes and confronts Tyler about it, telling him to back off and to apologize to Luke. She also reminds him that he was one of the people she resurrected when he gets angry about Luke's "solution" for helping Elena cope with Damon's death.
In Welcome to Paradise, she hesitates to come to the party at the watering hole when Tyler invited her but later comes. After the party she almost shares a kiss with Tyler.
In The World Has Turned and Left Me Here, Tyler hits a man with his truck causes the fire in the corn maze, Liv suffocates the man just before he dies therefore being the one to kill him and preventing Tyler from triggering his werewolf gene.
In Fade Into You, sees Liv attending "Friendsgiving" with her brother, Tyler, Caroline, Liam, Elena and Jo. While Luke is more upbeat, showing old videos of him and Liv as children, Liv seems more distant and angry, revealing that she and Luke are twenty-two and that their Coven has plans for them. While watching the childhood video, Jo recognizes it and they come to the conclusion that she's their eldest sister. It's after this that Liv and Luke reveal that, as twins, they'll have to "merge" at some point with the stronger twin absorbing the power of the other while the weaker one dies, thus allowing the survivor to become the future leader of the Coven.
In Christmas Through Your Eyes, the twins conspire with their older brother Kai against their sister Josette to avoid having to merge themselves. Luke arguing again with her sister, because he wants to submit to the will of the Coven because he thinks it is their duty to merge. Liv makes it clear to him that she doesn't want be an martyr for their coven because they were the backup twins for it. Liv later gives Jo an pep talk telling she has accomplished a lot ever since she left the coven.
In Woke Up With a Monster, Liv trains Jo after 18 years of being magic-less. So she has an chance against Kai for winning the merge. Later when Damon and her head down to the high school where Kai has Elena held hostage, but Luke forcibly takes her away back to Whitmore so they can go back to Portland. Liv knows she told their dad what she been doing and she admits she knows Luke will win the merge between since he's stronger. Later Luke tells her they're not going back home because he's willing to defy their coven because he doesn't want to kill her.
In Prayer For the Dying, Tyler and Liv are in bed together, when someone knocks at the door. Liv quickly remembers that today was the day that her father was coming over. She throws Tyler some clothes and shoves him behind the door where he couldn't be seen. Liv opens the door to be greeted by her father. He wishes her a happy birthday and reminds her about dinner later with Luke. Once her father had gone, Tyler seemed angry that Liv hadn't told him that today was her birthday, she claimed that it was in another couple of weeks. Later, while walking, Tyler suggests to Luke that he should try talking with their father to try and persuade him to change his mind on the merge. Luke quickly denies the idea and says that it wouldn't work. At dinner with her father and Luke, Liv and Luke try and persuade him to delay the merge. At night, Luke goes off looking for Kai. Once the merge had been completed, Liv's father sensed it and that Luke was dead. Liv seemed deeply saddened by this news, but before she had time to mourn, her father quickly suggested that they get out of there.
In The Day I Tried To Live, Liv is out for blood on Kai for killing her brother. She first puts Tyler to sleep with a simple spell, gently guiding him to the floor then leaving him there to go after Kai. Before she went after Kai, she put a barrier spell on Damon's room trapping Damon and Elena there so that they wouldn't inter fear with her plans for Kai. While Kai is helping getting Bonnie back, Liv stabs Kai through the stomach breaking his spell to the Prison World. They both fling knives and forks at each other using their magic. They both do damage to each other before Jeremy, throws a fork at her neck giving Kai time to slip away, causing her to wander around the house. Damon, trapped in his room, listens closely and realizes that Liv is directly below him. He then breaks open a hole in his fireplace so that it joins on with the other fireplace downstairs, and drops some alcohol onto the roaring fire, blowing Liv off her feet and across the room. Later, she wakes up with no injuries what so ever. Beside her was a unhappy Tyler, stating that Elena saved her with her blood. Tyler then seems unhappy that she never even put a pillow under his head. He then says that their over and walks out, leaving Liv calling after him.
In I'll Wed You in the Golden Summertime, Liv returns for Alaric and Jo's wedding. She picks a fight with Tyler after what has happened to them and what their relationship means to them. She then witnesses her older brother Kai stabbing Jo and destroying the rest of the church.
In I'm Thinking Of You All The While, after her father calls her name at the top of his voice, Tyler wakes up and looks around for Liv, who is under a pile of rubble. After removing the rubble, Liv sees that Tyler has a shard of glass through his stomach. She tells Tyler that something is wrong and that she thinks that she is dying. Tyler removes the shard of glass and suggests that he should go and get some help. Liv sees that Tyler is going to die from blood loss if he carries on, so she suggests that she sacrifices her life in order to enact Tyler's werewolf curse so that he heals because she was going to die anyway. Liv says that her death might as well help Tyler. Tyler refuses at first, but after Liv basically begs him to do it, he agrees. Then, he covers her nose and mouth with his hands, subsequently killing her and activating his werewolf gene.
As seen in Gone Girl, Liv was a bit of a flirt towards Jeremy. She was ambitious and likes to do things her way, instead of taking Bonnie's advice. It's shown that she's quite a talented actress, as she successfully manipulated Bonnie into thinking that she was a novice witch, when in reality she was quite talented. Liv had shown how determined she was to protect the doppelgängers and prevent the Travelers from succeeding. She was more than willing to kill Elena as a last resort. However, despite all of that, she was not all business. She really did care about Bonnie, despite having tricked her before. Also, she seems to be more personable than her twin brother, who refused working with Jeremy, Matt, and Tyler to protect the town from the Travelers.
Liv also had a sarcastic demeanor, but was also loyal, compassionate and dedicated to her coven. She was also protective towards her brother and has a flirtatious side towards Jeremy and Tyler.
Liv was a beautiful girl who was in her early twenties with long curly blonde hair and fair skin with a round face, dimple chin and bluish-greenish eyes. She was of average height, at least 5’8 with dark shaded eyes and a usually serious and unhappy expression.
Liv had proven to be a very capable and powerful witch. Her control over telekinesis was highly advanced being able to throw away an SUV.
She herself claimed she had been studying witchcraft since her childhood and mentioned that she had already mastered a simple locator spell in the 3rd grade.
She proved powerful enough to be able to cast a privacy spell without any incantations, something Bonnie had a hard time learning and figuring out.
Her most powerful feat was the Resurrection spell she performed by channeling all the power of the dead travelers. It allowed her and Bonnie to bring back 6 people, though as one by one, they came through, the spell began to kill Liv which forced Luke to stop it. In later episodes, many times, Luke was able to overpower her.
She eventually revealed that she knew for a while that Luke was stronger than her. Since Luke was planning on dying in the merge, she told him to reevaluate that decision because she was going to die instead because she wasn't as strong as him.
Liv is of Old Norse origin, derived from the name Hlif meaning "protection". Its use has been influenced by the modern Scandinavian world liv meaning "life". Liv is a short form for the English name Olivia.
Parker is a English family name, and means "keeper of the park" from Old French.
