He's your first love. I intend to be your last. However long it takes.Klaus [to Caroline]
Klaus: What are you afraid of?
Caroline: You. I'm afraid of you.
Klaus: It's a trick, Elijah.
Elijah: No. It's a gift.
Klaus: What an entirely unwelcome surprise.
Elijah: And what an entirely unsurprising welcome.
We evil villains usually use minions to pick up our dry cleaning and that sort of thing.
I've done more than enough. I've shown kindness, forgiveness, pity...because of you, Caroline. It was all for you.
Well, if it isn't Little Orphan Lockwood. Come to show how laughably impotent you are against me?
Klaus: Your brother's lack of communication is infuriating.
Damon: It's one of his trademarks. Like his brooding and his hair.
Klaus: I think you need a lesson in how to dagger a sibling.
Rebekah: Burn in Hell.
Mayor Lockwood: Klaus, please, don't hurt him. He's my son. He's all I have.
Klaus: And you're all he has. There's a beautiful symmetry to that, don't you think?
Stefan: Well, Jeremy is the hunter, and he has to keep killing vampires to complete his mark, but we can't quite figure out how to keep him from killing us.
Klaus: Sounds like quite the chore, which is why I feel perfectly justified doing a little charity work.
Loneliness, Stefan. That's why me and you memorialize the dead.
