The Vampire Diaries, Season 4

Caroline:
(as they search Shane's office) What are we even looking for?

Stefan:
Well, if Shane really was working with Silas, chances are he was helping him plan his next move.

Caroline:
Where, on his evil villain to-do list? 'Steal blood, perform 3 massacres, pick up dry cleaning'?

Klaus:
Actually, not to nit-pick, but we evil villains usually use minions to pick up our dry cleaning, that sort of thing.

Caroline:
(to Stefan about Klaus) Why is he necessary again?

Stefan:
Well, we don't know what Silas can do, so if we do have to go head to head with him, an Original hybrid who can't die might come in handy.

Klaus:
Besides, Stefan and I work well together, or at least we did in the twenties.
