Rick was of two minds about the matter. On the one hand, he wasn't sure if he wanted to be around to deal with the fallout of everyone in the building dealing with whatever little confessions they had to make. Like Micah, Rick assumed that everyone else was going through the exact same thing they did. Most of them would be confessing dirty little secrets about stealing people's lunch money in fourth grade, but for some people that kind of thing was traumatic. Rick dealt with trauma a lot, and he wasn't interested in taking on more.
However, he felt a certain kinship with the building and its peculiarities, and though he didn't give a damn about most of the people within its walls, he now felt a bemused sense of I-in-Team in relation to Micah, Stefan and Will. Particularly Micah, since he screwed up more than the other ones. Rick seemed largely unconcerned and showed no great emotional discomfort when they were again in the lobby, and he met Micah's there's-something-seriously-wrong-with-you look with an innocuous smile. (He tried not to grin.)
Following him up the stairs without any difficulty, even taking two at a time with his newly acquired here-now-there feline grace, Rick said, "What kind of something do you want to set up? Beach towels? Therapy booths?" He wasn't joking, if his tone was any indication. "What and how are you going to verify?"
