Salva was a sociopathic kid who killed animals, completely detached from reality and Rosalie tried to stop him, after accidentally killing her in the struggle, he fell in love with her dead body and now he tries to make zombies in the image of Rosalie...

Darin should have seen already after reading her father diary when she was about 10yo or so, that her father is really,
REALLY fucked up sociopath. Kill him and run.
Dunno now, if it's good that Salva nearly wiped Rea traumatic experience her pedophile father made to her by lobotomizing Rea or bad now she can't remember the happy times with Chihiro...
