"I'm going to get a drink of water. Then I'll clean the shit up so it doesn't stink." [His response was a very clear avoidance of a straight answer. Costigan was not okay in any sense and, though he was pretending to be just fine--and succeeding in his expression, his posture, and even his tone--, he saw no reason to lie to his warden. Not about this. The fact that Dick had closed the door instead of following him in meant something and he wasn't going to discard that.

The former undercover said nothing else as he walked down the hall and headed toward the stairs to go get some water and wash his mouth out. He should probably change shirts too, but maybe after he cleaned up. After all, the both of them had smelled enough vomit to last a lifetime and Costigan would rather go without the scent some more if he could help it.]
