i may be slightly biased here but either cain or bradley. not much explanation needed for cain's, not being able to see people sucks very much. as for brad the thing about it, it's made to kind of counter himself. the spontaneity of it is really troubling. i've seen people say 2 things about it: that it's a cry for freedom while being under the twins imprisoned and that it's a symbol to show just how unpredictable he can be in the eyes of others and i really agree with both of those interpretations. but also at it's core teleporting after a really normal thing your body just does sometimes is fucked up and inconvenient. mithra would also have it bad but it looks like the story is omitting the consequences of not sleeping like your brain literally shutting down but if it didn't mithra would have it the worst.
