My idea of Will's copy-making
To me Will can make copies of himself that fully share his memories and then make their own once they're detached, and when he's healthy he can just fuse back with them.
Maybe he can also control the amount of consciousness he gives them but in 120 he was so scared he might die and that's why he made 3 perfect copies that could continue on in his place if Stabbed!Will was to die.
The control of the amount of consciousness he can give the copies makes me think of HSY from ORV lol. But Will doesn't have to give away memories
But I also saw people say that the memories the copies made and og Will's memories merge if they fuse back together, and as much as Will making a copy just to fetch him a peach downstairs is funny, I really like this theory so he probably wouldn't make copies often in that case.
I feel like it'd make him go absolutely crazy and insane, he'd start to not see the line between his memories and the copies' and that's just pure horror fuel I love it
All that said I believe it's highly possible none of the Wills in the recent episodes were the og, but they might've forgotten it ? I would love to see something similar to what happened to Twice in BNHA go down with Will haha, with all the copies thinking they're the original and a big fight starts. Maybe with just one copy tho, I don't see Will needing a lot, whatever the reason might be.
But then where's the og Will ??
