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?
