@killaqueen41 Considering his whole being is losing his idea and that he's the combo of two people, I would not be surprised if his stand erased ideas and/or time like King Crimson. Or more specifically he could just use Soft and Wet to remove them. That'd be wack.
@killaqueen41 Another thing is that in real life I'm sure each different personality has different postures, different facial expressions, and different voices. (To some extent) I saw one dude claiming that each different personality has different allergies, but I'm sure that's fake.
@killaqueen41 https://my.clevelandclinic.org/health/diseases/9792-dissociative-identity-disorder-multiple-personality-disorder It doesn't seem like a persons appearance changes at all. That seems to come from JJBA and Split. But since we do see appearance change in Jojos, it wouldn't be far...
@killaqueen41 One thing about Disassociate Personality Disorder is that it's possible for the different personalities to be a different age and for appearance to change. Maybe Araki really exaggerated that and made this kid look like an 89 year old man. That's obviously a massive stretch, but...
@jjmangajames It seemed like he got along with Kira when he wasn't messing with his head, they would talk all the time after all. But it seems as if he was destroyed mentally for a bit after a long time of just dealing with it.
