Stefan: I had a chance to kill her and I hesitated.
Damon: Well, that is the fork in the road between you and me, my friend. I don't hesitate.

Katherine: I'm impersonating my dull-as-a-dishwasher-doppelganger, Elena. She had the worst taste.
Lucy: Except in men.

Damon: The second the spell is lifted, I'm gonna drive a stake right through your heart.
Katherine: God, you're heart. When did you get so hot?

Katherine: Have I mentioned how inconvenient your obsession for me as been?
Damon: You and me both, honey.

Katherine: So, here we are: the brother who loved me too much and the only who didn't love me enough.
Damon: And the evil slut vampire who only loved herself.

Katherine

Katherine [to Matt]

Jeremy: We're gonna kill Katherine.
Stefan: I can explain.
Bonnie: Please.
Stefan: We're... gonna kill Katherine.

You aren't gonna kill Katherine... I am.

Stefan
