Is there a specific team that Tim will be taking along with him during his explorations, or would it just be Tim on his own? We would be happy to build up details suitable to the team he's taking, including how far he would be able to get with them.

There are utility access areas hidden behind walls (areas to keep the plumbing of the cells separate and easily accessible for maintenance workers, for example), as well as air ducts Tim would be able to tuck himself inside of. However, Tim would not escape notice for long at all, and he would quickly have prison guards as well as bots chasing after him. The security hub has a massive computer terminal within it. The most Tim will be able to get off the hub is surveillance footage from the prison itself, including the time Jason and Roy spent in their cells and various logs recording what they (and the mystery third prisoner) had been up to during their time. The third log, labeled "X" documents the mystery prisoner's time - including meal times, what had been eaten off the tray (usually close to nothing, or just the items still sealed in their packaging), logged times spent in the rec area, usually an hour twice daily out in the sunning area, and miscellaneous smaller details like when they had requested a new book, attempts to break their way through the cell walls, the drowsy effect the power inhibitors built into the walls have on them and how they have been responding to it.

Regarding the rest - we'll build this information based on Tim's team!
