Bruce Banner / Hulk

— How's he doing?
— Oh, unfortunately, he's still Barton.

Natasha Romanoff: — You sure he's going to be okay? Pretending to need this guy really brings the team together.
Helen Cho: — There's no possibility of deterioration. The nano-molecular functionality is instantaneous. His cells don't know they're bonding with simulacrum.
Bruce Banner: — She is creating tissue.
Helen Cho: — If you brought him to my lab, the regeneration cradle could do this in twenty minutes.
Tony Stark: — Oh, he's flatlining. Call it. Time?
Clint Barton: — No, no, no I'm going to live forever. I'm gonna be made of plastic.

— How'd a nice girl like you wind up working in a dump like this?
— Fella done me wrong.
— You got lousy taste in men, kid.
— He's not so bad. Well, he has a temper. Deep down he's all fluff. Fact is, he's not like anybody I've ever known. All my friends are fighters. And here comes this guy, spends his life avoiding the fight because he knows he'll win.
— Sounds amazing.
— He's also a huge dork.
— Hmm.
— Chicks dig that.

— Sorry!
— Don't turn green!
— I won't!

— We're time bomb.
— You need to step away.
— Why shouldn't the guy let off a little steam.
— You know damn well why. Back off!
— I'm starting to want you to make me.
— Yeah. Big man in a suit of armour. Take that off, what are you?
— Genius, billionaire, playboy, philanthropist.
— I know guys with none of that worth ten of you. I've seen the footage. The only thing you really fight is yourself. You're not the guy to make the sacrifice play, to lay dawn on a wire and let the other guy crawl over you.
— I think I would just cut the wire.
— Always a way out. You may not be a threat, but you better stop pretending to be a hero.
— A hero? Like you? You're a laboratory experiment, Rogers. Everything special about you came out of a bottle.

— I don't think we should be focusing on Loki. That's guy's brain is a bag full of cats. You could smell crazy on him.
— Have care how you speak. Loki is beyond reason, but he is of Asgard. And he is my brother.
— He killed 80 people in two days.
— He's adopted.

— Because Stark is right.
— Oh, it's definitely the end times.
