[Tony tries to lift the Mjölnir]
Tony Stark: Alright so if I lift it then I rule Asgard?
Thor: Yes, of course.
Tony Stark: I will be reinstituting prima nota.
[None of the Avengers can lift the Mjölnir, but Captain America moves it slightly]
Tony Stark: It's biometrics, right? Like a security code? "Whoever is carrying Thor's fingerprints" is, I think, the literal translation.
Thor: Yes, well that's a very, very interesting theory. I have a simpler one: You are not worthy.
[an attack occurs]
Ultron: [enters] Worthy? How could you be worthy? You're all killers. You want to protect the world, but you don't want it to change. There's only one path to peace... your extinction.
Ultron: [to the Avengers] I know you're good people. I know you mean well. But you just didn't think it through. There is only one path to peace... your extinction.
Ultron: Stark asked for a savior, and settled for a slave.
Vision: I suppose we're both disappointments.
Ultron: [laughs] I suppose we are.
Vision: Humans are odd. They think order and chaos are somehow opposites and try to control what won't be. But there is grace in their failings. I think you missed that.
Ultron: They're doomed!
Vision: Yes... but a thing isn't beautiful because it lasts. It is a privilege to be among them.
Ultron: You're unbelievably naïve.
Vision: Well, I was born yesterday.
Tony Stark: Thor didn't say where he was going for answers?
Steve Rogers: Sometimes my teammates don't tell me things. Kind of hoping Thor would be the exception.
Tony Stark: Yeah, give him time. We don't know what the Maximoff kid showed him.
Steve Rogers: Earth's mightiest heroes... pulled us apart like
cotton candy.
Tony Stark: Seems like you walked away alright.
Steve Rogers: [stares at Tony] Is that a problem?
Tony Stark: I don't trust a guy without a dark side. Call me old fashioned.
Steve Rogers: Well let's just say you haven't seen it yet.
Tony Stark: You know Ultron's
trying to tear us apart, right?
Steve Rogers: Well, I guess you know. Whether you'd tell us is a bit of a question.
Tony Stark: Banner and I were doing research...
Steve Rogers: -That would affect the team.
Tony Stark: -That would END the team. Isn't that the mission? Isn't that the 'why we fight'? So
we get to go home?
Steve Rogers: [Splits wood with bare hands] Every time someone tries to win a war before it starts, innocent people die. Every time.
Iron Man: [Entering a room full of Hydra soldiers] Guys, stop. We gotta talk this through.
[Shoots all the Hydra men non-fatally with tiny guided missiles]
Iron Man: It was a good talk.
Fortress Soldier: No, it wasn't!
Pietro Maximoff: [speeding off with Wanda] Keep up, old man!
Hawkeye: [Draws his bow and points it at Pietro's back] Nobody would know. Nobody. "The last I saw him, Ultron was sitting on him. Uh... yeah, he'll be missed. That quick little bastard. I miss him already..."
[Jogs after them]
[after fighting off Ultron drones]
Thor: IS THAT THE BEST YOU CAN DO?
[Ultron laughs, and summons more drones]
Steve Rogers: You had to ask...
Ultron: [With his arms outstretched] THIS is the best I can do. This is what I've been waiting for. All of you against all of me!
[Battle ensues]
