The Vampire Diaries, Season 4

Damon:
Enough. You are acting like a little spoiled brat. You know that? You think that we can't punish you. Maybe not. But I can sure punish him.

Matt:
(weakly) Elena.

Elena:
Seriously you think that this is...

Damon:
Shut up. I'm done playing nice. Turn your emotions back on right now, Elena, or so help me, God, I will give you something to be sad about. I will kill him right here in front of you.

Stefan:
Damon.

Damon:
Don't "Damon" me. If she doesn't love anyone, fine. Prove it. And if I'm wrong, what difference does it make? One less bus boy.

Matt:
Elena...

Elena:
Your bluffing.

Damon:
(snaps Matt's neck) How about now. Feel anything now? You angry I just turned your buddy into road kill? Or are you sad that the guy that everybody loves is just a bag of bones? Remember when he was a little kid, huh? Warm heart, big, goofy smile, his whole life ahead of him. I guess it was a good idea that he wearing this. (on Matt's hand is a Gilbert ring)

Elena:
Oh, God, Matt.

Damon:
You feel that weight lifting off your chest? That's joy. Because your friend isn't dead. That's emotion, Elena. That's humanity.
