TEXT: Northern Europe, 1520 [A Cottage] (A woman knocks on the door. A man opens it. It turns out that the woman is actually Nadia) Nadia: Good evening, sir. If I could trouble you for a moment. I'm looking for someone. Her name is Katerina Petrova. She was last seen outside of London in 1492. She's on the run. I need to find her. I need to ask her why she abandoned me Nowadays [A Warehouse] (Katherine is with Nadia) Katherine: Nadia? Nadia: Please. I need to know Katherine: Nadia, I'm right here. I'm right here Nadia: Uhh. I was dreaming how I searched for you from village to village Katherine: I know. I heard you. You said that I abandoned you. You were ripped from my arms as a baby. It's completely different Nadia: Not for a child without a mother Katherine: You know, all this guilt is really taking all the fun out of this mother-daughter outing. I'm sorry Tyler bit you, but you're not going to die Nadia: Did you ask Klaus for his blood? Katherine: Oh, my, you really are delirious. Nadia, he would love nothing more than to watch my daughter die Nadia: And you don't want to risk being outed Katherine: No, I don't. So, that's why I called him (Wes rejoins them) Wes: Nice to meet you. I'm Dr. Maxfield Katherine: And luckily for us, he'll love nothing more than to study your blood Wes: Werewolf venom isn't easy to come by Nadia: Get away from me Katherine: It's ok. Nadia, it's ok Wes: Listen to your mother. The venom in your blood is a toxin with basic chemical properties. Once I study its make-up, I can... Create the antidote Katherine: It's ok. Come on, come on, honey. There you go Nadia: If I'd known I just had to die to drag your attention from Stefan, I would have tried it a long time ago
SUMMARY:
Nadia is hallucinating from the werewolf bite back to her search for her mother and Katherine reaches out to Wes to try and save her. Stefan and Caroline tell everyone about Katherine being a passenger in Elena's body. Tyler tells them that he bit Nadia so they have to come up with a plan to lure Katherine out, but Katherine figures out they know it's her. For the second time, Bonnie and Jeremy must turn to Liv for help to locate Elena/Katherine. Damon baits Tyler, feeds on him, knocks him out, and takes off to seek revenge on Dr. Wes. Katherine goes to find Wes, but instead finds him dead after Damon killed him. Stefan takes Nadia back to the house and Bonnie comforts her, telling her she'll go to the Other Side, as Katherine comes to say good-bye to her daughter. She gives Nadia a dream about what their life could have been like, had she not been taken away. Katherine tries to run, but she's stabbed and killed with the traveler's knife by Stefan. Caroline and Tyler talk and come to a new understanding. Katherine's spirit goes to Bonnie and reveals she injected herself with a combination of werewolf venom and the ripper virus. She then fails to go to the other side and goes to hell instead.
