Steve Rogers: It's nice.

Bruce Banner: What? What is?

Steve Rogers: You and Romanoff.

Bruce Banner: No, we haven't... That wasn't...

Steve Rogers: It's okay. Nobody's breaking any bylaws. It's just she's not the most open person in the world. But with you she seems very relaxed.

Bruce Banner: No. Natasha, she's just... She likes to flirt.

Steve Rogers: I've seen her flirt, up close. This ain't that. Look, as maybe the world's leading authority on waiting too long, don't. You both deserve a win.

Bruce Banner: What do you mean "up close"?
