Steve Rogers & Tony Stark:

Steve: I don't mean to make things difficult. Tony: I know, because you're a very polite person. Steve: If I see a situation pointed south... I can't ignore it. Sometimes I wish I could. Tony: No, you don't. Steve: No, I don't. Sometimes... Tony: Sometimes I wanna punch you in your perfect teeth. But I don't wanna see you gone. We need you, Cap.

“No matter what. I promise you, if you need us, if you need me, I'll be there.”

Steve: I will miss you, Tony. Tony: Yeah?

Tony: How were you guys planning on beating that? Steve: Together. Tony: We'll lose. Steve: Then we'll do that together, too.

-

Tony: Well, like the old man said. Together.

Tony: I don't trust a guy without a dark side. Call me old-fashioned. Steve: Well, let's just say you haven't seen it yet.

Tony: Uh, actually, he's the boss. I just pay for everything, and design everything and make everyone look cooler.

Tony: What the hell? What just happened? Please tell me nobody kissed me? Steve: We won.

Tony: I need you to get to that engine control panel and tell me which relays are in overload position. What's it look like in there? Steve: It seems to run on some form of electricity. Tony: Well, you're not wrong.

Steve: You're not going alone! Tony: You gonna stop me? Steve: Put on the suit, let's find out. Tony: I'm not afraid to hit an old man. Steve: Put on the suit. 

-

Steve: Put on the suit! Tony: Yep!

Steve: Back off! Tony: Oh, I'm starting to want you to make me. Steve: Big man in a suit of armor. Take that off, what are you? Tony: Genius, billionaire, playboy, philanthropist.

Tony: Still, you are pretty spry, for an older fellow. What's your thing? Pilates? Steve: What? Tony: It's like calisthenics. You might have missed a couple things, you know, doing time as a Capsicle.

Steve: Mister Stark. Tony: Captain.
