Oliver Queenan: Okay, kid. Let's do this. Come on, spread 'em.
Dignam: Hey, what do you think you can pop somebody and there's a special card to play? That guy, Jimmy Bags whose jaw you broke happens to work undercover for the Boston Police Department.
Billy Costigan: I'm going fucking nuts, man. I can't be someone else every fuckin' day. It's been a year of this. I've had enough of this shit!
Dignam: Calm down, alright? Most people in the world do it every day. What's the big deal?
Billy Costigan: Well, I'm not them, alright? I'm not fucking them, okay?
Dignam: Exactly. You're nobody. You signed the papers, remember? Now we're the only two people on the face of this earth that even know you're a cop. How about we just erase your file, huh? How 'bout that? How about we erase your file and then bang, you're just another soldier for Costello open to arrest for I don't know how many felonies. Huh? What do you say we do that, Captain?
Billy Costigan: How about I fucking kill you, huh? How about I fucking kill you!
Oliver Queenan: That was a joke. Come on!
Dignam: That wasn't a joke. Just because you play a tough guy, doesn't mean you are one you lace-curtain, Irish fucking pussy!
Oliver Queenan: Hey, hey! Stop it! Break it up! Stop it!
Billy Costigan: Fuck you, motherfucker!
Oliver Queenan: Goddamn it, stop it! That's an order!
Oliver Queenan: For chrissake, be smart. If anybody's watching us now, how are we not supposed to arrest you? Come on, get in the car. Both of you, get in the car!
Queenan and Dingam are bringing in Costigan like they are arresting him so that they can talk to him about the stuff he found out while working undercover.
