The episode begins and Elena tosses and turns in bed, trying to sleep. She gets up to make tea and see Connor, the hunter she just killed, bloody and standing in her kitchen. He talks to her, asking if it's the first time she's killed a human. She calls for Jeremy, but Connor attacks her. She throws him off and picks up a kitchen knife. She drives it into his neck. Except that it's not Connor, it's Jeremy. And she just stabbed him. Luckily, he's wearing his ring. Elena calls Damon to help while Jeremy reboots. She doesn't want to talk to Stefan, he's been lying to her and she doesn't trust him. ..Read the full recap
Damon: You can rest easy, brother, we've figured out how to solve our little Elena problem.
Stefan: Yeah, well, now we have a bigger one...I lost her.
Damon: What? Again?
Elena: I can't believe this happened. What am I going to say to him?
Damon: Thanks for not ditching the family ring after it drove Ric crazy? You should've called Stefan.
Elena: I don't wan't to talk to him. He's been lying to me and hiding things from me. He compelled Jeremy to forget God knows what!
Damon: In all fairness, I mean, I think you killing him kind of trumps that.
Stefan: You're using your calm voice today. Who's getting killed?
Klaus: Not you, if that's what you're worried about.
Bonnie: You lost her?
Damon: Well, lost is a very strong word. We just technically don't know where she is.
Stefan: It's Klaus.
Damon: Time to face the music. Pay the piper. Dance with the devil.
Stefan: You know, I'm glad you find this amusing. If he finds out I told you about the cure, he’ll kill both of us.
Damon: Then quit avoiding him. I mean, it’s shady. Shady people get outed.
Bonnie: You need to kill a vampire.
Jeremy: Great, give me a stake, I'll kill Damon right now.
Damon: Easy Van Helsing, we’ll get you one.
