[Costigan was stressed and his patience suffered as a result. With someone like Costello, he had no choice but to be patient, which was why he took it out on Madolyn the first time they'd met. But here? There was pretty much only one person he wouldn't flip out on. Maybe two, if his warden turned out to be a worthwhile person.]

"Fuck you, alright?" [The inmate closed the door behind him, locking it and then listening in silence for a few seconds to ensure he wasn't obviously followed. Yeah, he was paranoid.] "I'm trying to help you out here, to do you a fucking favor, and you're going to-- what? Threaten me? Refuse to listen to my orders when I might fucking know a thing or two more than you about this floor and who's around?"

[It was obvious he was serious about what he said. It was just as obvious that he was more stressed than their last good talk and increasingly anxious too.] "If you want this to work? We need to work out a fucking arrangement. Because I'm fucking sick of this shit."
