Hospitalizing Yaniv would suit him just fine. Let's say okay, he gets Form 4'd, because somehow 2 doctors miss that he has a history of histrionics and aggression with no credible threats against himself. Great. Now you've thrown him into a ward full of vulnerable women who cannot legally leave. He can spend all day every day asking them for tampons and flashing his vag in their shared bathrooms and he knows there is nothing that the staff or those women can do about it without a credible-sounding transphobia allegation aimed at them via the BCHRT. The psych ward is a REWARD for his kind of crazy. Same with jail. Captive lady audience and guards that can he can accuse of abuse/score free cavity checks off of to feel more like a real lady.
The best place for him is an intractable opiate addiction that leads to the DTES, and from the sounds of that wound, things are looking up!
