Main Cast

Recurring Cast

Guest Cast



  • Antagonists: Qetsiyah (past), Silas, Gregor and Nadia Petrova (present).
  • This episode marks the first appearances of Qetsiyah and Amara in the series.
  • This is the first episode this season to feature four main cast members.
  • It is revealed Qetsiyah is the one who saved Stefan, and that the man killed by Stefan after he was released from the safe was the owner of the cabin in which the two were staying.
  • Katherine appears to be fully recovered from the injuries she suffered in I Know What You Did Last Summer, which implies that some time has passed since True Lies.
  • Elena continues to have nightmares of Stefan that are accompanied by an unsettling feeling that something was wrong with him. Katherine also began to have the same dreams.
    • It was later revealed by Qetsiyah/Tessa that she magically gave them the dreams in order to draw them to her and Stefan.
  • It is revealed that Katherine's blood now contains the cure since she was the first person to ingest it. It was also revealed that both Silas and Qetsiyah want Katherine for that reason—Silas, so he can fulfill his plan of destroying the Other Side, becoming mortal, and killing himself to be reunited with his true love Amara; and Qetsiyah so she can force-feed Katherine's cure-laced blood to Silas and kill him before he can destroy the Other Side to ensure that her plan for revenge is finally successful.
  • Stefan becomes the first person (aside from Jeremy) to learn that Bonnie died after Qetsiyah informs him that she took advantage of "the Bennett witch" lowering the veil to the Other Side (which occurred from The Walking Dead to Graduation) and used her magic to resurrect herself.
    • However, Stefan's brain sustained so much damage during the spell Qetsiyah cast to link him to Silas that he lost all of his memories, and he subsequently forgot that he was informed of Bonnie's death.
  • Stefan loses all his memories after a spell done by Qetsiyah to link him to Silas in such a way that it would disable his psychic abilities and prevent him from reading anyone's mind. As a result, he awakens afterward with no memories or knowledge about any of his family, friends, or acquaintances, which includes Elena, Damon, and the rest of the Mystic Falls Gang.
  • Elena, Damon and Katherine meet Nadia for the first time in this episode.
    • Additionally, Katherine unknowingly meets her biological daughter for the first time since she gave birth to her and was subsequently forced to give her up for adoption in 1490. However, Nadia keeps the fact that she is Katherine's daughter a secret for the time being.
  • Qetsiyah reveals that Amara is the progenitor of the Petrova bloodline, and that Tatia, Katherine, and Elena are doppelgängers as a result of her consumption of the immortality elixir with Silas in sometime in 100 BC.
  • Qetsiyah makes the decision to have everyone call her Tessa, as she believes it's easier to pronounce and sounds less "ancient-timey."
  • This is the first episode in Season Five to feature Stefan more than Silas.
  • This is the first instance where Nina Dobrev plays three of the four known Petrova doppelgängers (Elena, Katherine, and Amara, though the latter was only in flashbacks) in one episode.
  • It is revealed that Silas fell in love with Qetsiyah's handmaiden Amara, who was the progenitor of the Petrova bloodline and the woman who spawned the female line of doppelgängers. Because of the love he felt for her, he left Qetsiyah at the altar of their wedding and stole the immortality elixir Qetsiyah had made for the two to drink together so he could share his new-found immortality with Amara instead.
  • Damon's epic "You are my life" confession to Elena in this episode was declared the scene of the week in an online poll.1


  • This is the second time that Nina Dobrev plays three different roles in a single episode: Elena, Katherine and Amara. The first time was in the Season Four finale (Graduation), where she played Elena, Katherine and Silas.
  • Qetsiyah appears for the first time in this episode. She was last mentioned in Graduation.
  • Qetsiyah claimed to have reversed Amara's immortality and killed her. This was proven to be a lie in Handle with Care.
  • Thought not revealed until Monster's Ball, Damon correctly guesses that Nadia is European.
  • Stefan lost his memories of everyone he's ever known and everything he's ever done in this episode as a result of the spell cast on him by Qetsiyah to link him to Silas. He will not have his memories returned to him until the end of Handle with Care.

Cultural References


Katherine: (to Elena) "Do you really think that I want to take a road trip with you? America's most boring, self-righteous vampire?"

Qetsiyah: (to Stefan) "I'm Qetsiyah-- that sane, rational, well-adjusted woman you seem to know so much about. Clearly you've heard the man's version of the story. The one where I'm a back-stabbing lunatic that ruined everything for Silas; a raging bitch-witch whose obsession with vengeance created a whole new dimension of suffering in the afterlife."

Qetsiyah: (to Stefan) "I'm a complicated person... but Silas remains a simple man."

Qetsiyah: (to Stefan) "Have you not been listening to me!? I have trust issues. I'm controlling... and paranoid... and a little crazy. And that's working out just fine."

Katherine: (to Elena) "I can't believe I am saying this, but I am really glad it's you!"

Damon: (to Elena) "No one tells me how I live my life. No one tells me who I love-- especially not some vindictive prehistoric witch, and definitely not the universe. And I'm not gonna let someone else's idea of destiny stop me from loving you, or being with you, or building a future with you, because you are my life."

Qetsiyah: (to Damon) "Silas had his true love and Stefan has Elena. We're merely the conflict that makes it interesting."

Silas: (to Katherine) "You know, it's funny-- the love of my life looked exactly like you, and yet the mere thought of your face makes me want to vomit."
