[While he's documenting everything, I should elaborate and say that in addition to all of the head injuries he's been seeing, they're also layered on and overlapping with what look like traces of older injuries in the same region -- mostly-healed cuts, scrapes, bruises across the head and face. The edges of the fresher wounds and bruises also look unusual -- that part of the bruises looks closer to the older injuries, and the edges of the wounds look almost like they're already scarring.

The coat looks like one of the regular coats from the storage locker outside the cold storage (which is separate but connected by the hallway outside). Examining it and the scant snow on it closely will reveal a number of glass shards sprinkled and stuck in the fabric of the coat, so it's a good thing he didn't just go for it right off. Examining the reverse side of the coat will reveal that its inner lining is spotted and smeared with blood.

Beneath the coat, Nona is wearing comfortable sweatpants and a hamburger T-shirt -- there's the glint of glass shards here and there on this outfit too. There's some frays and tears in the fabric, but there's no visible wounds otherwise.]
