sure! so, this is mostly just talking about his place within it and i apologize, and a lot of it is actually tweakable on second thought. but! the key pieces are that there's three kids, and while cair was born deaf and lost his vision starting around 7-8ish, his family never learned asl and i think that's the crux of it - that familial lack of knowledge of deaf culture and asl is something that's integral to his character. he has a super tense relationship with them now because of how they handled it and rarely sees their parents, but it's sort of a complex situation in that they... truly thought they were doing the best thing for him? i.e. it isn't as if they were outwardly terrible in any way, they were classically decent parents. he's engaged to ~kaczynski and has mostly adopted that crew as his own. his relationship with his siblings could go whichever way, honestly, there's a bunch of options there?
