Steve Rogers / Captain America

— But if you put the hammer in an elevator...
— It would still go up.
— Elevator's not worthy.

— So stand. Outwit the platinum bastard.
— Steve doesn't like that kind of talk.
— You know what, Romanoff?

— Fury, you son of a bitch.
— Oooh! You kiss your mother with that mouth?

— Wait a second. No one else is going to deal with the fact that Cap just said... "language?"
— I know. It just slipped out.

Cap: Sorry, Tony, you know I wouldn't do this a had any other choice, but he is my friend!
Tony: So was I!

— We're the Avengers. We can bust arms dealers all the live long day, but... that up there? That's... that's the end game. How were you guys planning on beating that?
— Together.

Steve: That wasn't so bad.
Doc: That was penicillin.

— Thor didn't say where he was going for answers?
— Sometimes my teammates don't tell me things. I was kinda hoping Thor would be the exception.
— Yeah. Give him time. We don't know what the Maximoff kid showed him.
— "Earth's Mightiest Heroes." Pulled us apart like cotton candy.
— Seems like you walked away all right.
— Is that a problem?
— I don't trust a guy without a dark side. Call me old fashioned.
— Well let's just say you haven't seen it yet.

— You know Ultron is trying to tear us apart, right?
— Well I guess you'd know. Whether you tell us is a bit of a question.
— Banner and I were doing research.
— That would affect the team.
— That would end the team. Isn't that the mission? Isn't that the "why" we fight, so we can end the fight, so we get to go home?

The rest of us have one job: Tear these things apart. You get hurt, hurt 'em back. You get killed, walk it off.
