First off, on season one I already assumed that dude was going to be named the killer, but not because I'm actually astute or anything. I just figured it has to be one of the rich people because rich people are always shady af. With all their resources & connections & excessive paranoia bc of their excessive wealth. 😒
Also he's creepy. & he has weird hair. That hair was the biggest tip off, though, tbh. 😂
The real surprise there really was that the wife wasn't in on it because she's creepy af too.
Earlier on I considered that it was Cheryl & that her parents covered it up for her, because Cheryl's pretty creepy too, but her ice queen mask cracks at times- like, she was way too emotional too often over any Jason news & she even moped about having creepy robots as parents.
Also at one point my theory was that Jason's not even dead, but that's because I completely forgot about the "bloated corpse".
