All they knew was that your dad had an unregulated compound that could cure most injuries
Elena: Vampire blood
Wes: Exactly, but as Megan grew up, she got suspicious, enrolled at Whitmore, roomed with Dr. Gilbert's daughter, and she went to a party at Whitmore house and put her nose where it didn't belong
Elena: She found Enzo in his cell
Wes: And being clueless to what a starving vampire will do around fresh human blood, I'm guessing she got too close
(His phone rings. Elena: What is that thing? Elena: You're a monster
Maxfield: This isn't my journal, Elena. Get out of here. Go back to bed
(Katherine is about to leave when Damon enters)
Katherine: What the hell happened to you? Gregor was a Traveler. Her father rejoins her)
Grayson: Hey. I'm leaving Mystic Falls, and I need to know it's safe
Matt: Why? Katherine? Maxfield: Everything I'm doing to you, I learned from him
[Whitmore College]
(Stefan and Damon are still with Aaron)
Aaron: I have no idea where Wes took her
Stefan: Well, they're not at his lab, so where else could he hide a vampire? Megan is 7 years old. Nadia: I thought I could convince Katherine to live a little longer. Nadia: That's for trying to kill yourself without saying good-bye
[Whitmore College]
(Aaron, Damon and Stefan are walking)
Stefan: You want to give me a little back story as to how you know one another? No, Damon
Damon: I am choosing to not have to think about how you must feel every time some ghost from my past comes into our life. Please. See? Seriously. She was selfish, and she drank too much and never really thought about how it would affect me
Nadia: Then you know what it's like to hold on to the hope that maybe just once she'll do what you want
Matt: If she changes her mind, the knife will be with me
[Whitmore College]
(Enzo wakes up in Wes' lab. Stefan: He doesn't care. Stefan: We have Aaron, and we're trying to decide how to kill him
Wes: Funny. That's why Megan had a picture of my dad on her phone... because he saved her life
Damon: A hundred pages of horrific torture and you find the one happy passage
Elena: My dad used his research to save people, Damon, children, families
Damon: Yeah. Wes: Who's this? What's wrong with you? Where's Elena.Tell me where she is! You never see her again? [Salvatore's House]
