[At night, a slum in India it attacked by a sickness. A little girl runs into the middle of a makeshift hospital in someone's home, pushing through the crowd frantically. She runs up the steps inside to greet the only doctor, Bruce Banner. They begin speaking in Hindu.]

ATTENDING WOMAN: What are you doing here?! Get out! You shouldn't be here.

LITTLE GIRL: I have to see the doctor. It's my father.

BRUCE: Calm down. What's wrong?

LITTLE GIRL: My father... [she looks to the other sick people, laying down and moaning in pain.]

"Help her please" Molly exclaimed

Bruce just looked at Natasha "I paid her" Natasha admits

BRUCE: Is he like them?

[The little girl holds out money, crumpled and looking desperate.]

LITTLE GIRL: [In English] Please.

[Banner and the little girl run quickly to the edge of town. She leads him quickly through narrow passageways, and is proving too fast to keep up with. Banner spots a nice car, and looks around, worried. He runs into the girls house, when she leaves through a window, untraceable.]

BRUCE: Should have gotten paid up front, Banner.

NATASHA: [Entering the room behind him, making Banner turn around.] You know, for a man who's supposed to be avoiding stress, you picked a hell of a place to settle.

BRUCE: Avoiding stress isn't the secret.

NATASHA: Then, what is it? Yoga?

BANNER: You brought me to the edge of the city, smart. I uh... assume the whole place is surrounded?

NATASHA: Just you and me.

BRUCE: And your actress buddy, is she a spy too? Do they start that young?

NATASHA: I did.

Clint hugged his wife and Natasha relaxed into his touch, after being a bit on edge before. 

BRUCE: Who are you?

NATASHA: Natasha Romanoff.

"Barton" He whispered really close to her ear. 

BRUCE: Are you here to kill me, Miss Romanoff? Because that's not gonna work out for everyone.

NATASHA: No. No. Of course not. I'm here on behalf of SHIELD.

BRUCE: SHIELD. How did they find me?

NATASHA: We never lost you, doctor. We've kept our distance, even helped keep some other interested parties off your scent.

BRUCE: Why?

NATASHA: Nick Fury seems to trust you. But now I need you to come in.

BRUCE: What if I said no?

NATASHA: I'll persuade you.

BRUCE: And what if the... other guy says no?

NATASHA: You've been more than a year without an incident. I don't think you wanna break that streak.

BRUCE: [gently pushing a cradle] I don't always get what I want.

NATASHA: Doctor, we're facing a potential global catastrophe.

BRUCE: Well, those I actively try to avoid.

NATASHA: This is the Tesseract. It has the potential energy to wipe out the planet.

[She shows him a photo of the Tesseract on her cell phone. Banner takes a closer look.]

BRUCE: What does Fury want me to do? Swallow it?

NATASHA: Well, he wants you to find it. It's been taken. It emits a gamma signature that's too weak for us to trace. There's no one that knows gamma radiation like you do. If there was, that's where I'd be.

BRUCE: So Fury isn't after the monster?

NATASHA: Not that he's told me.

BRUCE: And he tells you everything?

"No" All the avengers say except for Natasha. Fury smirks at this. 

NATASHA: Talk to Fury, he needs you on this.

BRUCE: He needs me in a cage?

NATASHA: No one's gonna put you in a...

BRUCE: STOP LYING TO ME! [Banner slams his fists onto the table]

[Natasha grabs a gun hidden under the table, pointing it at him. Banner stays still, grinning]

BRUCE: I'm sorry, that was mean. I just wanted to see what you'd do. Why don't we do this the easy way, where you don't use that, and the other guy doesn't make a mess? Okay? Natasha...

[Natasha, still wary, doesn't lower her gun. She lowers her gun and speaks into her earpiece.]

NATASHA: [on her earpiece] Stand down. We're good here.

[Dozens of soldiers armed to the teeth have surrounded the small house, but at her signal they back off a bit.]

BRUCE: [smiles back at Natasha] Just you and me?
