Qetsiyah: When they drank the immortality elixir, they violated the natural law that all living things must die, so Nature found a balance by creating mortal shadow selves.
Stefan: Doppelgängers.


A Doppelgänger (or a "Shadow Self") is a person who happens to be a supernatural double of a person that has lived before them. They are Nature's way of balancing itself, by repeatedly creating mortal counterparts of truly immortal beings to live and eventually die in their place. For over two thousands years, Amara's and Silas' shadows have appeared over the centuries to take their places as mortal human beings. While their lives don't always follow an exact pattern they tend to find each other and fall in love with one another over the centuries.


Introduction of the Doppelgängers

While the term was first used in the series to merely remark upon Elena Gilbert's resemblance to Katherine Pierce, it soon becomes apparent that Elena is in fact a direct descendant of her lookalike, and the doppelgänger phenomenon is established not as a coincidence, but as a supernatural occurrence. Following further elucidation from members of the Mikaelson family, it is revealed that another doppelgänger of the so-called Petrova bloodline, Tatia, lived as a neighbor to the Originals when they became vampires. So far as the Originals knew, Tatia's doppelgängers were created as a means to undo the curse placed on Klaus. It isn't until the fifth season that this proves untrue. The bloodline terminating with Elena actually goes back about 2,000 years to Amara, the world's first immortal woman and the oldest known ancestor of the Petrova bloodline. Elena, along with Katherine and Tatia, are the known doppelgängers of Amara. Amara's doppelgängers have, since Tatia, been known to be born 500 years after their precedent's death. Not much is known about the lives of the other doppelgängers, other than Qetsiyah's implication that there have been many of them over the centuries. The other known doppelgänger bloodline was not introduced until the Season Four finale. This second line descends from Silas, the world's first immortal being, and terminates with Stefan Salvatore. According to Qetsiyah, Stefan isn't Silas' first doppelgänger, and there have been at least as many shadows of Silas as there have been of Amara.

Creation

The phenomenon of the shadow-self occurs to counterbalance a disruption to nature's law that all living things must die. Qetsiyah, one of the most powerful witches and member of a very gifted people called The Travellers, created a spell for immortality. Silas stole the immortality elixir and used it on himself and his lover, Amara. Disrupting that balance when they became truly immortal, Silas and Amara, inadvertently, became originators to lines of mortal shadow-selves. 

History

Silas and Amara: The World's First Immortals

Amarasilasqetsiyah
Amara, Silas, and Qetsiyah, the "original" (and most tragic) love triangle of the series

Over two thousand years ago in ancient Greece, a young warlock named Silas was engaged to be married to Qetsiyah, a witch. Together, they were the most powerful members of a gifted people called Travellers. Silas told Qetsiyah that he wanted their love to last forever, even beyond death, and he convinced her to create a spell that would make them immortal. On the night that their wedding ceremony was to take place, Silas absconded with the elixir Qetsiyah had created, and as Qetsiyah watched plant life wither before her eyes, she knew that not only had Silas taken the elixir, he had also given her portion to someone else. She sought out Silas and found him in the wilderness with another woman – her handmaiden, Amara - and she had taken Qetsiyah's share of the immortality elixir.

Silas, having left Amara alone, returned to their hiding place to find Qetsiyah crouching over the chalice that had held the elixir. He cautiously enquired after Qetsiyah's purpose, and she explained that, to follow up her first gift of the immortality elixir, she had brought a second gift: the cure for immortality. Silas was dumbfounded, hardly believing her, but she insisted that it worked, as she had already used it on another immortal. Filled with dread, Silas ran into the tent he had shared with Amara, only to find blood soaked into every surface, as though someone had been brutally slaughtered there. Qetsiyah followed him into the tent and lifted a bloody human heart out of the chalice, admitting that she had slit Amara's throat before ripping her heart out. After Silas refused to take the cure, Qetsiyah trapped him on a desolate island in an underground cave, where he desiccated for two thousand years, entombed with the cure.

One major consequence of Silas and Amara becoming immortal was the creation of two lines of shadows, or doppelgängers. Their immortality had violated nature's law that all living things must die, and so the doppelgängers came to exist as versions of Silas and Amara that can die. According to Qetsiyah, many identical replicas of Silas and Amara have been born over the centuries, finding each other time and time again as though drawn together by destiny. However, the exact number of doppelgängers that have existed is not certain, as only four doppelgängers have been identified by name: Stefan Salvatore is the only known Silas' doppelgänger that has been identified thus far as well as the recently discovered Tom Avery, an Atlanta Paramedic, while Tatia, Katerina Petrova, and Elena Gilbert have been identified as Amara's.

Tatia and the Original Vampires

Tatia was a descendent and a shadow of Amara. She lived in America during the 11th century as a contemporary of the Mikaelson family. Even though she had already had a child by another man, both Elijah and Klaus fell in love with her. Seeking to end their feud, their mother, Esther, took her away. They later learned that it was Tatia's blood that laced the wine they consumed the night their mother turned them into vampires. Although it has not been explicitly stated, it is inferred that it was Tatia that Esther sacrificed to bind the hybrid curse.

Katerina, Elena, and the Hybrid Curse

Main article: Hybrid Curse

The notion of the doppelgänger as a class of supernatural beings was introduced in the episode Rose by the character of the same name. Until that point, the term was used simply to describe Elena's uncanny resemblance to the vampire Katherine, but Rose explains that Elena is a "Petrova doppelgänger" and that she is one of the necessary components in a ritual to break the Sun and the Moon curse, which allegedly caused vampires to be ruled by the sun and werewolves to be ruled by the moon. Rose had originally tried to hand Elena over to Elijah, in an effort to earn back his and Klaus' favor, but after Elijah kills her friend Trevor, Rose decides to tell Elena and the Salvatores what she knows about Klaus. Rose's story is corroborated by Katherine, who tells Elena about how Klaus had wanted to use her in the sacrifice five hundred years before – to "drain every single drop of blood" from her body.

In the episode Klaus, Elijah reveals to Elena that the Sun and the Moon curse was fake, and the real curse was one that had been placed on Klaus to suppress his werewolf nature in order to prevent him from becoming a hybrid. He explains that five hundred years ago, Klaus had intended to sacrifice Katerina in the ritual, but she thwarted him by turning herself into a vampire, thus rendering herself useless – the doppelgänger had to be human for the ritual to break the curse.

In The Last Day, Elena surrenders herself to Klaus, and in The Sun Also Rises, after Jules the werewolf and Jenna the vampire have been sacrificed and their blood spilled over the moonstone by the witch Greta, Klaus drains Elena of her blood until she dies, and thus successfully breaks the Hybrid Curse.

Fortunately for Klaus, Elena actually survives the sacrifice, and in The Reckoning, Klaus discovers from Esther (via Bonnie and Matt, who had contacted Vicki on the Other Side) that the blood of the doppelgänger is required to create more hybrids like himself. After a werewolf drinks Klaus' blood and he kills them, once they reawaken they must drink Elena's blood in order to complete the transition and become a hybrid.

Silas' Return and Qetsiyah's Resurrection

In the twenty-first century, a man named Atticus Shane sets in motion a series of events that leads to the resurrection of the immortal Silas. Once he has regained his strength, Silas manipulates those around him to further his agenda: Bonnie must complete the Expression Triangle and destroy the veil, while Klaus must find the cure and return it to Silas. These things all occur to some extent – Bonnie completes the triangle and drops the veil, while Silas gets a hold of the cure – but Silas' plan goes awry when Bonnie subdues him and turns him to stone, and Alaric nabs the cure and gives it to Damon.

Later, while trying to resurrect Jeremy, Bonnie dies and the spell on Silas breaks. When Stefan is about to dump Silas' body into the quarry, Silas appears and reveals to Stefan his true form; they look exactly alike, and Silas explains that Stefan is his shadow self, before locking Stefan in a safe and dropping it into the quarry. 

Sometime when the veil was down, Qetsiyah managed to return from the Other Side in order to take matters into her own hands. After freeing Stefan and telling him her version of the story between her, Silas, and Amara, she uses Stefan in a spell to link him to Silas, then fries his brain, which in turn deprives Silas of his mind control abilities.

The Doppelgänger Prophecy

Stefan-Elena-Doppelgangers
Elena Gilbert and Stefan Salvatore, the last living descendants of Amara and Silas (the world's first immortal woman and man) respectively. Stefan and Elena are both doppelgängers of Silas and Amara and are presumably the 4th and last doppelgängers of Silas and Amara. This means that Stefan and Elena are descendants of an ancient 2,000+ romance between star-crossed lovers.

According to Qetsiyah, the doppelgängers of Silas and Amara, known as the Salvatore Doppelgangers and the Petrova Doppelgangers in the current or modern times, have been supernaturally brought together repeatedly, by destiny, nature and the universe. This is a result of the mortal shadow selves of Silas and Amara, who were soulmates and true love, being driven by destiny, fate, the Universe and Nature to replace their progenitors and originators due to both Silas and Amara being truly immortal and therefore, unkillable. It is uncertain whether or not the Salvatore Doppelgangers and the Petrova Doppelgangers were actually born every 100 years (as Qetsiyah seemed to have suggested) and whether or not the Petrova Doppelgangers stopped existing every century after 10th century A.D. when Tatia, the presumed 2nd Petrova Doppelganger, was used in order to turn the Mikaelson Family into vampires and was also used by Esther, the Original Witch, to suppress Klaus' werewolf side (a.k.a. The Hybrid Curse). Qetsiyah has said that she has seen them (Salvatore and Petrova Doppelgangers) all finding each other and falling in love with each other, century after century. She even goes so far as to say that she was simply an obstacle to the story of Silas and Amara, and that Damon is basically playing the same role to the story of Stefan and Elena. Qetsiyah has also said that despite the Salvatore Doppelgangers and the Petrova Doppelgangers being destined to be together, something or someone; an obstacle, always happens to come or stand between the "two fates". It should also be noted that despite the doppelgangers being destined to be together and the Universe and Nature pushing for them to be together, it is possible for the doppelganger to fall in love with other people. In regards to Qetsiyah admitting that she has seen endless shadow selves of Silas and Amara finding each other and falling in love over the centuries, she could have also meant that she has seen Silas and Amara's doppelgangers finding each other on The Other Side century after century, since doppelgangers are considered to be a supernatural species, and therefore, when doppelgangers die, they cross over to The Other Side. It is not certain if any of Silas and Amara's doppelgangers fell in love and had children together, although this theory is not likely. Despite nature's great hatred for immortality, it appears the doppelgängers continued to live the life that the immortal Silas and Amara couldn't have. It is currently unknown if the doppelgängers are the only determinants in this matter or if the universe actively influences a series of events that would lead them to be together. It is possible that since the last remaining doppelgängers are now vampires, nature does not try to enforce the prophecy as they will have an eternity worth of time to be together. It is also possible that nature will have indirectly rendered them impervious to any fatal harm as the prophecy wouldn't be fulfilled for as long as they keep away from each other. As of the current times, Stefan is the last living Salvatore Doppelganger in existance and Elena is the latest Petrova Doppelganger in existance, with Katherine preceding Elena by 500 years. Due to the fact that Stefan and Elena did not reproduce or have children and now that Silas and Amara are deceased, the doppelganger gene is extinct, with Stefan and Elena being the last of their kind (Stefan being the last Salvatore Doppelganger and Elena being the last Petrova Doppelganger).

Powers and Abilities 

  • Blood: Because they are mystical and recurrant, doppelgängers are a massive source of power such as a full moon or a comet. The blood of a doppelgänger can link supernatural beings (vampires, werewolves, witches and hybrids) to kinship with the help of magic conducted by any witch/warlock. The blood of a doppelgänger can also be used in the realization of a curse or spell which is extremely powerful. The blood of a doppleganger can still be used even if they've been turned into a vampire as seen in Death and the Maiden when Qetsiyah used Elena's blood to transfer the Anchor from Amara to Bonnie.

Known Doppelgängers

Amara's Doppelgängers

Amara's known doppelgängers are Tatia, Katherine and Elena, the latter two of which have appeared on-screen. Elena is sometimes referred to as the Petrova doppelgänger because of her striking resemblance to Katerina Petrova.

Tatia

Tatia was born during the 10th century A.D. in the area where Mystic Falls was to be formed. She was a contemporary of the Mikaelson Family around the early 11th century. During the Middle Ages, Tatia had a child with an unknown man; later in time, she met Elijah and Niklaus Mikaelson, both of whom fell in love with her (especially Klaus, according to Elijah). Esther, the mother of Elijah and Niklaus and also the Original witch, used Tatia's blood in the spell or ritual to create the Original Vampires, as part of the wine laced with blood in which Mikael had given his children. Her blood was also part of the spell Esther used to bind Klaus' werewolf side, which resulted in Klaus' werewolf gene being dormant.

Katerina Petrova

Katherine 109
Katerina was the doppelgänger and descendant of both Amara and Tatia. She is assumed to be the 3rd doppelgänger of Amara.

Katerina Petrova (a.k.a. Katherine Pierce) was born in Bulgaria during the 15th century on June 5th, 1473. In the year 1492, when she was still a human, she was captured by Klaus. She knew that she was going to die, so she tricked Trevor, one of Klaus' servants, into helping her escape. Katherine was clever, cunning and smart; she knew that if she became a vampire, she'd be rendered useless to Klaus. Katherine stabbed herself with a knife but was given vampire blood by Rose in an attempt to heal her stabbing wound and afterwards, Katherine hung herself and came back as a vampire. In return for her escape, Klaus made her suffer by killing her entire family in Bulgaria, thinking that the doppelgänger would never appear again. What Klaus didn't know was that Katherine had a child out of wedlock that was kept secret and this child continued the bloodline of the Petrova family, leading to the birth of Elena Gilbert. Tired from running, Katherine intended to make a deal with Klaus by giving him the ingredients he needed to break the curse in exchange for her freedom. She planned to hand over the moonstone, Elena Gilbert, Caroline Forbes (a vampire), Tyler Lockwood (a werewolf) and Bonnie Bennett (a witch). When Katherine was about to take out her own doppelganger, Elena shoves the cure, into her mouth. She is the doppelganger of Tatia and her doppelganger is Elena Gilbert. 

Elena Gilbert

Elena-Doppelganger-9
Elena is assumed to be the 4th doppelgänger of Amara. She is the doppelgänger of Katherine and a distant descendant of Amara, Tatia and Katherine.
Elena Gilbert was born in Mystic Falls, Virginia during the 20th century on June 22nd, 1992. Elijah was the first one who found out about Elena before Klaus. At first, when Rose told Elijah about this, he didn't believe it. But soon enough he found out that the Petrova family line didn't end with Katherine because she had given birth to a baby girl that was given away by her father, thus continuing the Petrova bloodline. Once Klaus learned of the Petrova doppelgänger, Elena, he came to Mystic Falls, and he kidnapped Katherine, temporarily taking over the body of Alaric Saltzman. As with Katherine, Klaus is responsible for the death of Elena's family, most notably their aunt Jenna Sommers, Elena and Jeremy's legal guardian. He terned Jenna into a vampire and killed her for the sacrificial ritual. Unlike with Katherine, Klaus successfully killed Elena and as a result, he breaks the curse. Fortunately for Elena, John Gilbert had Bonnie form a special spell that bound Elena's life force or essence to his. This spell brought Elena back to life, but in return, killed John and took his life. In The Departed, Jeremy took Elena to Mystic Falls Hospital after discovering her lying unconscious at home. Meredith Fell discovered Elena was suffering from a serious cerebral hemorrhage and secretly injected her with vampire blood to heal her. This action fortunately saved Elena from death. The same day, Rebekah ran Elena and Matt off Wickery Bridge to save her siblings from Alaric, since his life force was tied to Elena. That way, if she died, so would Alaric. Jeremy arrives home to see Alaric, and he talks to him and Jeremy realizes that he is a ghost, and that if he is dead, that means his sister, Elena, must also be dead. Stefan hurried to Wickery Bridge, intending to save Elena, but she insisted that he save Matt's life instead, who was unresponsive after crashing into the water. By the time Stefan pulled Matt out of the water, Elena had drowned and died. Stefan brought her body back to Mystic Falls Hospital, where she woke up, transitioning into a vampire with Damon's blood in her system. She is the last of Amara's doppelgängers and being a vampire the line ends with her.

Silas' Doppelgängers

Stefan Salvatore

Stefan-Doppelganger-8
Stefan is assumed to be the 4th doppelgänger of Silas. He is also a very distant descendant of Silas. Stefan is currently the last living Silas Doppelgänger in existence.

Stefan Salvatore was born in Mystic Falls, Virginia during the 19th century on November 5th, 1846. He was turned into a vampire along with his brother Damon in the year 1864 by Amara's distant descendant, Katherine Pierce. Like his ancient ancestor Silas, Stefan was involved in a love triangle with Katherine and Damon. Stefan was unaware of the fact that he was a doppelganger during his human years and that he was turned into a vampire by Amara's very distant descendant Katherine. Stefan was turned into a vampire against his will; Katherine had been compelling Stefan to consume her vampire blood for weeks. When Katherine is captured by the Founders Council Members, Stefan and Damon plot to rescue Katherine from being burned in a church by fire. Although Stefan and Damon do end up rescuing Katherine, Stefan and Damon are both shot dead by their own father Giuseppe. It was then that Stefan transformed into a vampire. When he first transitioned, Stefan suffered from severe hunger for blood and therefore, had problems controlling himself around human blood. Regarding the bloodline of Silas, not too much is known about it, its background and its history. Qetsiyah mentioned to Stefan that she has seen doppelgangers of Silas preceding Stefan while watching from The Other Side.

Riptom
Tom is assumed to be 5th and last doppelgänger of Silas. He is killed by Enzo

Tom Avery

He is killed by Enzo. A new doppelgänger of Silas is discovered in the episode While You Were Sleeping, a paramedic who resides in Atlanta, Georgia. In Rescue Me it is revealed that he was kidnapped by the witch Hazel and put in a comatose state under a cloaking spell in order to protect him from The Travellers. He is later found by Caroline and Enzo. Caroline snaps Enzo's neck in order to prevent him from killing Tom. Caroline then takes him to a diner and compels him to tell her about his life. Confirming he is a good person, she compels him to run, far from The Travellers and Enzo. Before he can leave, however, Enzo catches up to them and snaps his neck, killing him making Stefan the last living doppelgänger of Silas.

Myths

  • In some traditions, when a doppelgänger is seen by a person's friends or relatives, the contact prophesies illness or danger, while a person seeing their own doppelgänger is an omen of death.
  • In other traditions or legends, a doppelgänger is connected with the person copied; sometimes causing the feelings of injuries between the original and the doppelgänger. For example, if the doppelgänger is injured, the other person will also be hurt or feel pain.
  • "Doppelganger" is a German word or term meaning "double walker" or "double goer"―a shadow self that is thought to accompany every person. Traditionally, it is said that only the owner of the doppelganger can see this phantom self and that it can be a harbinger of death. Occasionally, however, a doppelganger can be seen by a person's friends or family, resulting in quite a bit of confusion. 
  • The word doppelganger is a loanword from German, written there (as any noun) with an initial capital letter Doppelganger, composed from doppel, meaning "double", and ganger, as "walker". In English, the word is conventionally not capitalized, and it is also common to drop the German diacritic umlaut on the letter "a" and write "doppelganger", although the correct spelling without umlaut would be "doppelgaenger".
  • The term has, in the vernacular, come to refer to any double or look-alike of a person, most commonly in reference to a so-called evil twin, or to bilocation. Alternatively, the word is used to describe a phenomenon where you catch your own image out of the corner of your eye. In some traditions, seeing one's own doppelganger is an omen of death. A doppelganger seen by friends or relatives of a person may sometimes bring bad luck, or indicate an approaching illness or health problem.
  • The doppelgangers of folklore cast no shadow, and have no reflection in a mirror or in water. They are supposed to provide advice to the person they shadow, but this advice can be misleading or malicious. They can also, in rare instances, plant ideas in their victim's mind or appear before friends and relatives, causing confusion. In many cases once someone has viewed his own doppelganger, he is doomed to be haunted by images of his ghostly counter-part.
  • Other folklore says that it is considered unlucky to try to communicate with a doppelgänger.

Trivia

  • According to Qetsiyah, the shadows of Silas and Amara are destined to find each other and fall in love, based on her observations throughout the centuries. However, evidently, they are also capable of developing romantic feelings for other people. Examples include:
    • Elijah and Katherine
    • Elena and Damon
      • Despite this, the Universe, Destiny and Fate always finds a way to overcome these obstacles and bring the doppelgängers back together again. 
  • The term doppelgänger doesn't seem to imply any hierarchy.
    • Qetsiyah has, in one instance, mentioned Silas as Stefan's doppelgänger.
    • Silas himself referred to Amara as Elena's doppelgänger.
    • Silas and Stefan can be called doppelgängers of each other. Similarly, Tatia, Katherine, Elena and Amara are all doppelgängers of each other since they are all lookalikes of each other. 
  • The term "Shadow" has some implied hierarchy as opposed to doppelgänger.
    • Katherine referred to Elena as her shadow self and Silas did the same to Stefan.
    • Elena is the shadow of Amara, Tatia and Katherine, while Katherine is that only of Amara and Tatia.
  • Doppelgängers are humans for most intents and purposes. However, they are a supernatural occurrence and are therefore, considered to be a supernatural species. The difference between regular humans and doppelgängers is that spells that use a doppelgänger can be broken using another doppelgänger.
  • Death by a doppelgänger counts as a supernatural death. A person wearing a Gilbert ring comes back to life if killed by the doppelgänger.
  • The Gilbert rings do not protect supernatural creatures and is, thus, theorised not to work on a doppelgänger. It has never been confirmed.
  • They can, however, be compelled by vampires like any regular human.
  • It seems that the men who spend a lot of time with doppelgängers of Amara can't help but fall in love with her or fall vulnerable to her charms. Back in the 11th century, it was stated that every man in the village fell in love with Tatia, though Elijah and Klaus more than any others. Trevor, Elijah, Damon, Stefan, and Mason fell in love with Katherine, and Noah was obsessed with her. Matt, Stefan, and Damon fell in love with Elena.
  • Katherine and Elena both became vampires, though Katherine has been cured and is now human.
  • Silas and his doppelgänger, Stefan, have first names beginning with the letter "S".
    • Seeing as Amara's doppelgängers follow a pattern in naming (with all of their first names ending with the letter "A"), it is reasonable to assume that the other unknown doppelgängers of Silas follow this pattern of having first names which begin with the letter S. 
  • All of the known shadows of Amara, like herself, have first names that rhyme with each other. All of the known Petrova doppelgängers, including the progenitor Amara, all have first names which end with an "A" (AmarA, TatiA, KaterinA, ElenA). 
  • Aside from Tatia, Katherine and Elena, there is presumed to be another doppelgänger of Amara who precedes Tatia, born during c. 5th century A.D. She is presumed to be Amara's very first doppelgänger, although this is not confirmed and is just a theory. 
  • Although Tatia, Katherine and Elena are known to be Amara's 2nd, 3rd and 4th doppelgänger respectively, it is a possibility that they might be the 9th, 10th, and 11th doppelgängers of Amara, since it has been implied by Qetsiyah, that there have been many shadows of Amara that have been born century after century before Tatia, Katherine and Elena. It is also a possibility that the 500 year span for every Petrova doppelgänger to be born theory could prove to actually be untrue.  
  • A person and his or her doppelgänger will look identical in appearance, but the differences stem from their rearing and community standards (such as their expressions, speech, reason, and connections with others).
  • According to some myths, doppelgängers tend to undo the lives of each other. Tatia was used to create Originals but her doppelgängers have influenced the deaths of all three deceased Originals.
    • Katherine distracted Mikael, which let Klaus have a shot at his heart.
    • Elena shot Finn with a crossbow to disable him for a few moments before Matt killed him.
    • Elena held down Kol, which led to Jeremy weakening him with vervain, and then killing him.
  • Now that Stefan has been revealed to be a doppelgänger of Silas, in retrospect, it seems more than just a mere coincidence that Stefan too influenced the deaths of the three originals.
    • Stefan intervened when Damon tried to take a shot at Klaus which led to the death of Mikael.
    • Stefan took the first shot at Finn and was disarmed immediately by Sage. In his process of recovering the stake, Elena shot Finn with the crossbow.
    • Stefan spent an entire evening trying to obtain the dagger from Rebekah which, at the very least kept her at bay, while Elena and Jeremy went about killing Kol.
  • On more than one occasion, Katherine has actively harmed her doppelgänger Elena. Silas made his doppelgänger, Stefan, suffer for a whole summer by stabbing him, locking him in a safe and throwing the safe off a cliff into the water under a quarry, where Stefan would drown repeatedly and die over and over for three months. 
  • The very danger, of being prematurely undone by his doppelgänger, is probably why Silas locked Stefan in the safe and left him to drown repeatedly - he might have wanted to keep Stefan out of the way for as long as he remains immortal. As it turns out, Stefan's release from the safe allowed Qetsiyah to neutralise Silas' mental powers.
  • The term "Petrova Doppelgänger" comes from the last name of Katherine Petrova, the third doppelgänger of Amara. It is a term used by those who strived to find Katherine's doppelgänger and once discovered, directly referred only to Elena.
  • Qetsiyah has said that the Silas' and Amara's doppelgängers have been finding each other and falling in love century after century. This could possibly imply that before the 10th century, when Tatia, the second doppelgänger of Amara, was used by Esther to make the Mikaelson family vampires and was also used to suppress Klaus' werewolf side, there were possibly Petrova doppelgängers being born every century or every few centuries, since Qetsiyah said that they fall in love century after century, not every 500 years. 
  • It is uncertain whether or not the doppelgängers of Silas are born every 500 years like the last three doppelgängers of Amara have. It is also uncertain if Petrova doppelgängers being born every 500 years theory is actually true. 
  • It is possible that the doppelgängers are finding each other and falling in love on The Other Side. Doppelgängers are known to be supernatural beings and hence, would go to The Other Side when they die. This could possibly be what Qetsiyah meant when she said she has watched versions of Silas and Amara find each other and fall in love century after century. She has been watching them find each other and fall in love on The Other Side.
  • Even if Elena had children, there is possibility that the doppelgänger line would no longer be active since Amara, the progenitor of the Petrova Doppelgänger bloodline, is now deceased.
  • Doppelgängers can be born or the doppelgänger "gene" can be passed down the bloodline without the doppelgänger himself/herself having children or a direct bloodline due to having children. For example, Silas and Amara, the progenitors of the Salvatore and Petrova Doppelgänger bloodlines respectively, were assumed to not have had any children before they became truly immortal. Therefore, it is very likely that they had a sibling(s) which would have passed down the doppelgänger "gene" through Silas and Amara's respective bloodlines. So doppelgängers do not need to have children in order for the doppelgänger "gene" to be passed down the bloodline as in the case of Silas and Amara, whom were the progenitors. It should be noted that all of the known Petrova doppelgängers (i.e. Tatia and Katherine) with the exception of Elena due to becoming a vampire, have had children. It could be assumed that Silas' doppelgängers all had children as well, with the exception of Stefan, since he became a vampire and therefore, could not reproduce. 
  • The two known doppelgänger lines are, both, the result of the Immortality Spell being cast. It is possible that other spells (such as the Hybrid Curse initially) may also produce doppelgängers depending on their nature.
  • Doppelgänger blood seems to be of special interest or importance to The Travellers, a subculture of witches. What The Travellers interest is in the blood of doppelgängers remains to be unknown.
  • As of fifth season of The Vampire Diaries, both Amara and Silas had become mortal and died.  Theoretically, being cured of immortality and their deaths means the end of their doppelgänger lines, as nature would no longer require their shadow selves to die in their places.
  • Since Tom Avery was born in the 20th century chances are is that he was meant for Elena, had she not met Stefan. If the prophecy holds truth than that means that Stefan may have never been meant to meet neither Katherine or Elena or fall in love with them. Katherine may have had another SIlas Doppelganger for herself and Stefan would have had a Petrova Doppelganger for himself, while Elena had Tom. If of course the prophecy means two doppelganger being born in the same century fall in love with each other or that depending on who meets who first.
