Natasha Romanoff: You're not going to put me in a prison. You're not going to put any of us in a prison. You know why?
Member of the Congress: Do enlighten us.
Natasha Romanoff: Because you need us. Yes, the world is a vulnerable place, and yes, we help make it that way. But we're also the ones best qualified to defend it. So, if you want to arrest me, arrest me. You'll know where to find me.
Natasha Romanoff: All right, I have a question for you, which you do not have to answer. I feel like, if you don't answer it though, you're kind of answering it, you know.
Steve Rogers: What?
Natasha Romanoff: Was that your first kiss since 1945?
Steve Rogers: That bad, huh?
Natasha Romanoff: I didn't say that.
Steve Rogers: Well, it kind of sounds like that's what you're saying.
Natasha Romanoff: No, I didn't. I just wondered how much practice you've had.
Steve Rogers: You don't need practice.
Natasha Romanoff: Everybody needs practice.
Steve Rogers: It was not my first kiss since 1945. I'm 95, I'm not dead.
(Hydra operatives are getting close...)
Natasha Romanoff: Kiss me.
Steve Rogers: What?
Natasha Romanoff: Public displays of affection make people very uncomfortable.
Steve Rogers: Yes, they do.
(Natasha kisses Steve...)
Natasha Romanoff: You still uncomfortable?
Steve Rogers: It's not exactly the word I would use.
Steve Rogers: Wait, are you talking about a time machine?
Scott Lang: No. No, of course not. No, not a time machine. This is more like a... Yeah. Like a time machine. I know, it's crazy. It's crazy. But I can't stop thinking about it. There's gotta be... some way... It's crazy.
Natasha Romanoff: Scott. I get emails from a raccoon... so nothing sounds crazy anymore.
Nick Fury (about Hulk): Probably jumped out and swam to Fiji. He'll send a postcard.
Natasha Romanoff: "Wish you were here." You sent me to recruit him way back when. Did you know then what was gonna happen?
Nick Fury: You never know. You hope for the best, then make do with what you get. I got a great team.
Natasha Romanoff: Nothing lasts forever.
Nick Fury: Trouble, Ms. Romanoff. No matter who wins or loses, trouble still comes around.
Tony Stark: Romanoff. You and Banner better not be playing "hide the zucchini."
Natasha Romanoff: Relax, shellhead. Not all of us can fly. What's the drill?
Tony Stark: This is the drill. If Ultron gets a hand on the core, we lose.
Thor: Is that the best you can do?
(Ultron calls in his androids)
Steve Rogers: You had to ask.
Ultron: This is the best I can do. This is exactly what I wanted. All of you against all of me. How can you possibly hope to stop me?
Tony Stark: Well, like the old man said... (looks at Steve) together.
Natasha Romanoff: Cap, these people are going nowhere. If Stark finds a way to blow this rock...
Steve Rogers: Not till everyone's safe.
Natasha Romanoff: Everyone up here versus everyone down there? There's no math there.
Steve Rogers: I'm not leaving this rock with one civilian on it.
Natasha Romanoff: I didn't say we should leave. There's worse ways to go. Where else am I gonna get a view like this?
