Natasha Romanoff / The Black Widow

— So stand. Outwit the platinum bastard.
— Steve doesn't like that kind of talk.
— You know what, Romanoff?

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!

— At long last is lasting a little long, boys.
— Yeah. I think we lost the element of surprise.

Can any of you boys direct me to the Smithsonian? I'm here to pick up a fossil.

— Natalie!
— Ms. Potts…
— Don't you Ms. Potts me!

— You'll break them.
— Only the breakable ones. You are made of marble. We'll celebrate after the graduation ceremony.
— What if I fail?
— You never fail.
<... >
— Pretending to fail. The ceremony is necessary, for you to take your place in the world.
— I have no place in the world.

There was an idea...
To bring together a group of remarkable people...
To see if we could become something more...
So when they needed us we could fight the battles...
That they never could.

— Boy, you're good. You are mind-blowingly duplicitous. How do you do it? You just tear things... You're a triple impostor. I've never seen anything like you. Is there anything real about you? Do you even speak Latin?
— Fallaces sunt rerum species.
— Which means? Wait. What? What did you just say?
— It means you can either drive yourself home or I can have you collected.
— You're good!

Hey big guy. Sun's getting real low.

— 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.
