The Vampire Diaries, Season 4

Stefan:
Damon, help me celebrate my 17th high school graduation. Hey! You remember my friend Lexi, of course.

Damon:
Lexi back from the dead. Goodie.

Lexi:
What's up, buzz kill?

Damon:
Stefan, you just gonna sit there and let her enact her ghostly revenge?

Stefan:
You reap what you sow, buddy.

Lexi:
Let's be very clear. Whatever time I have left here I sure as hell don't plan on wasting on you. Got me?

Damon:
Yeah. Got you. So if you and Ric and little Gilbert are all flesh-like and real-seeming, that means something went horribly wrong when Bonnie tried to put the veil up, and here you two are having "Dance Party USA".

Stefan:
You're right. How selfish of me to be indulging in these precious moments with my formerly dead best friend. I should be sacrificing my own happiness for the good of others, right? I should be upstairs grooming my hero hair.

Damon:
Are you drunk?

Stefan:
I don't know, mom, am I?

[Lexi laughs]

Damon:
Well I guess that's one way to celebrate our supernatural apocalypse. Now care to hazard any guesses in what the hell went wrong?
