All you have to do is get Stefan to stop decapitating my friends.
Stefan: Friends don't strip friends of their free will.
Klaus: Okay, granted, that was a little extreme.
Klaus: My sister has gone missing.
Damon: Cute. Blonde bombshell. Psycho. Shouldn't be too hard to find.
Human life is just a means to an end. Our means, to our end.
Your mom is not a problem. I compelled her to go to the church and pray for your friends.
The only thing stronger than your craving for blood is you love for this girl.
Elena: You don't have to hurt anybody.
Klaus: Oh, cone on love, of course I do.
Rebekah: I am not a brat!
Klaus: A thousand years of life experience says otherwise.
Stefan: I remember you. We were friends.
Klaus: We are friends.
I'd forgotten what it was like to have a brother.
Stefan: You shouldn't be here.
Elena: Where else would I be?
Klaus: I see they've opened the doors to the riffraff now.
Damon: Honey, I've been called worse.
