I think his sister is in the woman side of the prison, not the monster
I thought so too but the age doesn’t seem to fit? Even when the girl first showed up I thought about that and isn’t she mentioned to be a kid while 182 is teenager or young adult at least? Dante never mentioned him looking too particularly young. But in flashbacks the siblings seem around similar age and size.
Meanwhile the kid in women’s group seems super short and her mother was mentioned but no brother.
It’s possible of course, just that we need some more info on their ages so the theory has some basis besides only white hair.
Im just saying that cuz there's practically no reason to show woman side of prison other than showing someone important in the lore, cuz as far as it went it gave us pretty much nothing but just new side characters/extras
IS HIS SISTER THE MONSTER OUTSIDE?!
