[in the lab]
Bruce Banner: What's the rumpus?
Stark: Well, the scepter. You see, we were wondering how Strucker got so inventive. So, I've been analyzing the gem inside you may recognize.
[Stark brings up a 3D image of Jarvis's consciousness]
Bruce Banner: Jarvis.
JARVIS: Doctor.
Stark: Started out, JARVIS was just a natural language UI. Now he runs the Iron Legion. He runs more of the business than anyone besides Pepper.
Bruce Banner: Oh.
Stark: Top of the line.
Bruce Banner: Yes.
JARVIS: I suspect not for long.
Stark: Meet the competition.
[Stark brings up another 3D image of what's inside the scepter]
Bruce Banner: It's beautiful.
Stark: If you had to guess, what's it look like it's doing?
Bruce Banner: Like it's thinking. I mean this could be a...it's not a human mind, it...
Stark: Um-um.
Bruce Banner: I mean, look at this! They're like neurons firing.
Stark: Down in Strucker's lab I saw some fairly advanced robotics work. They deep-sixed the data, but...I gotta guess he was knocking on a very particular door.
Bruce Banner: Artificial intelligence.
Stark: This could be it, Bruce. This could be the key to creating Ultron.
Bruce Banner: I thought Ultron was a fantasy.
Stark: Yesterday it was. If we can harness this power, apply it to my Iron Legion protocol.
Bruce Banner: That's a mad-sized if.
Stark: Our job is "if." What if you were sipping margaritas on a sun-drenched beach turning brown instead of green? Not looking over your shoulder for VERONICA.
Bruce Banner: Don't hate, I helped design VERONICA.
Stark: As a worst-case measure, right? How about a best-case? What if the world was safe? What if next time aliens roll up to the club, and they will, they couldn't get past the bouncer?
Bruce Banner: The only people threatening the planet would be people?
Stark: I want to apply this to the Ultron program. But JARVIS can't download a data schematic this dense. We can only do it while we have the scepter here, that's three days, give me three days.
Bruce Banner: So you're going for artificial intelligence and you don't want to tell the team.
