(After Damon tried to compel and kiss Elena...)
Damon Salvatore: Guess I could just seduce her... the old-fashioned way. Or I could just eat her.
Stefan Salvatore: No. You're not gonna hurt her, Damon.
Damon Salvatore: No?
Stefan Salvatore: Because deep down inside, there is a part of you that feels for her. I was worried that you had no humanity left inside of you... that you may have actually become the monster... that you pretend to be.
Damon Salvatore: Who's pretending?
Stefan Salvatore: Then kill me.
Damon Salvatore: Well, I'm tempted.
Stefan Salvatore: No, you're not. You've had lifetimes to do it, and yet, here I am. I'm still alive. And there you are. You're still haunting me. After 145 years. Katherine is dead. And you hate me because you loved her, and you torture me because you still do. And that, my brother, that is your humanity.
(Elena and Damon are talking about Katherine...)
Elena Gilbert: What was she like?
Damon Salvatore: She was beautiful. A lot like you in that department. She was also very complicated and selfish, and at times not very kind... but very sexy and seductive.
Elena Gilbert: So which one of you dated her first?
Damon Salvatore: Nicely deduced. Ask Stefan. I'm sure his answer differs from mine.
Stefan Salvatore: That's what this is about? You wanna expose me?
Damon Salvatore: No, I want you to remember who you are.
Stefan Salvatore: Why? So, what? So I'll feed? So I'll kill? So I'll remember what it's like to be brothers again? You know what? Let her go. Let her tell everyone that vampires have returned to Mystic Falls. Let them chain me up. And let them drive a stake through my heart. Because at least I'll be free of you.
