Damon: None of this matters to me, none of it.
Elena: People die around you. How could it not matter? It matters, and you know it.
Elena: I think that you’re hurt.
Damon: Nooo, I don’t get hurt, Elena.
Elena: No, you don’t admit that you’re hurt.  You get angry and cover it up and then do something stupid.  
Elena: “Friends don’t manipulate friends, they help each other."
Damon: Upset is an emotion specific to those who care.
Elena: C'mon, Damon, you care.
