Chas has a lot of injuries - grab marks from two sets of hands, bite marks, scratches, and,um, the sort of bleeding/tearing you would get from really, really rough, no-preparation sex with someone who is 8 foot tall and size-proportioned.
What would be the procedure for this sort of a thing? Where woudl they take Chas? Who would be asking him the uncomfortable questions cause they would assume he was raped? What would they do with Zladko - would he be directed to a room to pace and wait for Chas to be fixed up and the boys in blue to arrive?
the story is not set anywhere specific so that does not matter - any procedure or anything useful is welcomed.
