Your world in the balance, and you bargain for one man? (eng)

Loki: There's not many people that can sneak up on me.
Natasha Romanoff: But you figured I'd come.
Loki: After. After whatever tortures Fury can concoct, you would appear as a friend, as a balm. And I would cooperate.
Natasha Romanoff: I wanna know what you've done to Agent Barton.
Loki: I'd say I've expanded his mind.
Natasha Romanoff: And once you've won. Once you're king of the mountain. What happens to his mind?
Loki: Is this love, Agent Romanoff?
Natasha Romanoff: Love is for children. I owe him a debt.
Loki: Tell me.
Natasha Romanoff: Before I worked for SHIELD, I uh...well, I made a name for myself. I have a very specific skillset. I didn't care who I used it for, or on. I got on SHIELD's radar in a bad way. Agent Barton was sent to kill me, he made a different call.
Loki: And what will you do if I vow to spare him?
Natasha Romanoff: Not let you out.
Loki: Ah, no. But I like this. Your world in the balance, and you bargain for one man?
Natasha Romanoff: Regime's fall everyday. I tend not to weep over that, I'm Russian, or I was.
Loki: And what are you now?
Natasha Romanoff: It's really not that complicated. I've got red in my ledger, I'd like to wipe it out.
Loki: Can you? Can you wipe out that much red? Drakoff's daughter? Sao Paulo? The hospital file? Barton told me everything. Your ledger is dripping, it's gushing red, and you think saving a man no more virtuous than yourself will change anything? This is the basest sentimentality. This is a child at prayer. Pathetic! You lie and kill in the service of liars and killers. You pretend to be separate, to have your own code, something that makes up for the horrors. But they are a part of you, and they will never go away.
Loki: I won't barter Barton! Not until I make him kill you. Slowly, intimately, in every way he knows you fear. And then he'll wake just long enough to see his good work, and when he screams I'll split his skull!
Loki: This is my bargain, you mewling quim!
Natasha Romanoff: You're a monster.
Loki: Oh, no. You brought the monster.
Natasha Romanoff: So, Banner? That's your play?
Loki: What?
Natasha Romanoff: Loki means to unleash the Hulk. Keep Banner in the lab, I'm on my way. Set the door locked. Thank you, for your cooperation.
