It's kind of the same situation with Norman Bates of Bates Motel TV series, if you are familiar with that. He had Dissociative Identity Disorder and he sometimes switches as his mother. The condition got worse after her death, kinda like this story.
I almost get blind coz of norman
I cried super much
If you liked Bates Motel, try the Alfred Hitchcock film "Psycho" (⌒▽⌒)
Haven't watched it but of course it's the film the show was based on. I don't know for some reason I don't really want to watch it, though I know pretty much everything about it.
Ok hold one. So Coen suffers from multiple personality disorder.
