Elise's nerds miss her, and look for signs that she's still around, and they find some! Ghost Elise is hanging out to hook up  with Spirit Patrick to solve the mystery and get that mean lady out of his body. Turns out, the mean lady is actually a Norman Bates style dude, dressed up as his mother. The ghost of the fucked up mother traps an extra psychic and Rose in her old house, while the ghost of Norman Bates is running around in Patrick's body, getting ready to murder everyone. Oh, while he was alive the first time, he was a serial killer, and they find allllllllll the bodies. Wtf. So, the nerds and the new psychic come up with a crappy plan to take out Possessed Patrick, but it fails, and then everyone is in serious danger, as he goes Jack Torrence on the basement door.
