So Ginko's on the 7th floor, but he's a light sleeper and will probably be easily woken by the smoke.

He doesn't have any superpowers or anything so most of what he's likely to be doing is banging on doors and ushering people out. If anyone who's injured or can't walk/move well wants to have him carry your character out on his back, that could def be a thing! He'll also probably be that guy trying very hard to convince people not to go back in for their belongings.

I could also see him maybe getting some mild burns/minor injuries, so if anyone wants to play with the healing angle that'd also be good!
