The Vampire Diaries Season 3 Episode 17

Damon: I should eat you.
Sage: I'm 900 years old, Damon. You're not capable of ending me.

Alaric: Tell me again, why are we here?
Damon: Ric, the world can't stop just because you're an accidental psycho killer.
Meredith: Do you have any tact whatsoever?

Elena: (referring to Stefan) You stood there and let him feed on an innocent girl.
Damon: I didn't let him do anything. If you want to get nitpicky about it, I made him.
Elena: Why would you do that?
Damon: Because we're vampires, Elena. We need human blood to survive. We're predators, not puppies.
Elena: Well, Stefan found a way around it before.
Damon: Stefan just built himself a delusional wagon which he's repeatedly fallen off of. What he needs to learn is control.
Elena: He was able to manage when he was drinking my blood. Small amounts every single day.
Damon: Ah, yes! Back when you two were in love and it was all rainbows and unicorns.
