The Vampire Diaries, Season 5

Stefan:
You know, I was in a dark place, Damon.

Damon:
And Katherine pulled you out of it. Irony abounds.

Stefan:
You know, whatever is going on with you and Elena, you need to fix it. She's the best thing that ever happen to you.

Damon:
You think I don't know that? I can't live without her... But when you think about it, I'm no better than Katherine. Elena will be happier without me. What, I'm being selfless? Don't give me that look.

Stefan:
I'm not giving you a look.

Damon:
Katherine fricking Pierce has a selfless moment, I'm not allowed to? Fine. Fine. When I get Elena back and the whole universe freaks out because the fated Doppelgängers are torn apart, just remember you-- you're the one that pep talked me out of doing the right thing for the universe and all mankind.

Stefan:
I will keep that in mind.

Damon:
You do that.
