- Katherine Pierce: [regarding his haggard state] What happened to you?
- Damon Salvatore: Ditto. Elena's not here by any chance, is she?
- Katherine Pierce: I haven't seen her. Not that I've been looking.
- Damon Salvatore: [calling out to upstairs] Stef! You awake?
- Katherine Pierce: You know, he hasn't seen her either. I know, because we were together.

- Stefan Salvatore: A hundred and forty-seven years is... a long time to forgive in one night.
- Katherine Pierce: One night.
- [shakes her head]
- Katherine Pierce: An eternity. You'd never look at me the way you look at Elena, would you?
- Lorenzo 'Enzo' St. John: You were the most important person in my life, and you ruined me. That's just who you are. It's who you'll always be. A monster
