Human nature is the best, and the end is good.

Sofia: Ricky was a city planner, and some nights he would have to work late, so I-I would go to his office to finish my homework. I was waiting for Ricky by the elevator when these two men show up. I didn't see their faces, but they were looking for Ricky. I hid 'cause I didn't wanna get him in trouble. But they wanted something from him. Then all of them start yelling, and I hear this noise. They were hurting him. I could hear him screaming. And he tells them that he doesn't have it, that it's back at his place.

Michael MacCauley: You took it.

Sofia: Of course I took it. I wanted to help. And then I look through the doorway and I see this guy. He's holding Ricky, and he hits him, and he says something about being noble.

Michael MacCauley: Noble?

Sofia: He says that doing the right thing will get you killed, and that there's no such thing as being noble. And then, they just... I didn't... I didn't know what to do. I...

Michael MacCauley: I know.

Sofia: I just took it, and... and I ran.

Michael MacCauley: Why didn't you call the police?

Sofia: I couldn't call the police. The men who killed him were cops.

Michael MacCauley: So, I heard something earlier today, a hypothetical question.

Tony: Uh-huh. What was the question?

Michael MacCauley: What if someone asked you to do one little thing, something that's meaningless to you, but would affect another passenger on this train? Would you do it?

Tony: I don't know. What's in it for me?

Michael MacCauley: $100,000.

Tony: Absolutely!

Michael MacCauley: You don't even know what it is.

Tony: It doesn't matter. Come on.

Jackson: So, what is that one little thing?

Michael MacCauley: A passenger on this train doesn't belong. They're carrying a bag, but you don't know what it looks like. All you have to do is find them before they get off.

Tony: That's it? It's not much to go on, Mike.

Michael MacCauley: Tell me about it.

Jackson: And what happens when you find 'em?

Michael MacCauley: They die. Hypothetically.

Tony: So what would you do, Mike?

Michael MacCauley: I'd get all the people left on the train in one car, propose that very scenario.

Tony: No, no, no, no, no. I mean, would you take the money?

Michael MacCauley: You know what? I already did.
