Klaus and Damon in “Unfinished Business”

Klaus

Ah, what an unpleasant surprise.

Damon

So I just came up with a list called things you suck at. Number one: finding Katherine, ever. Number two: covering up your secret phone conversations to that little backstabbing Hayley. Yeah, so where is she, and what does she know about Katherine?

Klaus

I should help you? After you lot killed my brother and imprisoned me in the Gilbert living room.

Damon

You might want to prioritize Klaus, you have much bigger problems. Katherine has the cure. My guess is she's gonna want to cram it down your throat. You help me find Katherine., I'll get the cure, I'll give it to Elena, everybody wins.
