To everyone:

Essentially, feel free to write in what you want for the bathroom basics provided and for shit in your duffel bag(s), since your circumstances vary so wildly. Some--like Sander who came from a research facility--will have changes of clothing and other things, some may have barely anything. Some may have an in-between amount of crap. Etc. Keep it in line with what you think the authorities might have grabbed along with your character.

Edit: There is a window per room and it's about 60cm by 91cm. God, Piercing Light, have some mercy on me. I am only a sad potato of a human, haha.
