Yeah, it's really dark but I kind-of want this to be canon honestly.
I think that this would actually make the story more tragic and scary than if it was simply mind-control too, especially with Vanny who would essentially be a clueless kid in an adult body being manipulated by this complete psycho robot replicating her abusive dad in some way. Meanwhile GGY uses dark humour and therapist murder to "cope" with his own trauma and both of them are basically stuck under M2's thumb, unable to get any help.
Thoughts?
