SO GOOD NEWS.
My mom reports that Steel has greatly improved. Today, they took him off the ventilator, he's much less sedated, and has been talkative and such (my mom said he was irate that his nails had gotten long).
It's just in the nick of time, too, because literally tomorrow they were going to take him off the ventilator and like, give him a tracheotomy to help him breathe, because he was at the limit of being on a ventilator before negative health effects started happening.
SO YES, EVERYTHING IS SMASHING, for now! I'll talk to him tomorrow, if he's up to it.
