Elena: Do you think I like going behind your back? I don't. But if I hadn't asked Stefan to help, then you would have tried to be the hero, and you would have ruined everything.
Damon: Sorry for trying to keep you alive. Clearly Stefan doesn't give a crap anymore.
Elena: Now you're mad at me for including Stefan?
Damon: No, I'm mad at you because I love you.
Elena: Well, maybe that's the problem.
