[After Barton has taken the Cradle to Stark and Banner]
Bruce Banner: Anything on Nat?
Tony Stark: Haven't heard. But she's alive, or Ultron'd be rubbing our faces in it.
Clint Barton: This is sealed tight.
Bruce Banner: We're going to need to access the program, break it down from within.
Tony Stark: Hm. Any chance Natasha might leave you a message, outside the internet, old school spy stuff?
Clint Barton: There's some nets I can cast. Yeah, alright. I'll find her. [Barton leaves]
Bruce Banner: I can work on tissue degeneration, if you can fry whatever operational system Cho implanted.
Tony Stark: Yeah, about that.
Bruce Banner: [Banner looks at Stark] No.
Tony Stark: You have to trust me.
Bruce Banner: Kinda don't.
Tony Stark: Our ally? The guy protecting the military's nuclear codes? I found him. [he brings up the 3D image of Jarvis's consciousness]
JARVIS: Hello, Dr. Banner.
Tony Stark: Ultron didn't go after JARVIS cause he was angry. He attacked him because he was scared of what he can do. So JARVIS went underground. Okay? Scattered, dumped his memory. But not his protocols. He didn't even know he was in there, until I pieced him together.
Bruce Banner: So, you want me to help you put JARVIS into this thing?
Tony Stark: No, of course not! I want to help you put JARVIS in this thing. [Banner shakes his head] We're out of my field here. You know bio-organics better than anyone.
Bruce Banner: And you just assume that JARVIS' operational matrix can beat Ultron's?
Tony Stark: JARVIS has been beating him from inside without knowing it. This is the opportunity, we can create Ultron's perfect self, without the homicidal glitches he thinks are his winning personality. We have to.
JARVIS: I believe it's worth a go.
Bruce Banner: No, I'm in a loop! I'm caught in a time loop, this is exactly where it all went wrong.
Tony Stark: I know, I know. I know what everyone's going to say, but they're already saying it. We're mad scientists. We're monsters, buddy. You gotta own it. Make a stand. [Banner shakes his head] It's not a loop. It's the end of the line.
[In the Sokovia base]
Ultron: [as Natasha becomes conscious] I wasn't sure you'd wake up. I hoped you would, I wanted to show you something. I don't have anyone else. I think a lot about meteors, the purity of them. Boom! The end, start again. The world made clean for the new man to rebuild. I was meant to be new. I was meant to be beautiful. The world would've looked to the sky and seen hope, seen mercy. Instead they'll look up in horror because of you. You've wounded me. I give you full marks for that. But, like the man said, "What doesn't kill me..." [a bigger body of Ultron's destroys him] "...just makes me stronger." [he locks Natasha in a cell]
[Barton gets a Morse code message from Natasha which he's able to detect her location, at the same time Stark and Banner are experimenting on the synthetic body]
Tony Stark: This framework is not compatible.
Bruce Banner: The genetic coding tower's at ninety-seven percent. You have got to upload that schematic in the next three minutes.
