initial predictions
The rumors are that it's based on Gale and her backstory and hometown.
Which means it makes little sense for Marley Shelton to return.
Herego, Marley Shelton gets killed in the opening.
Herego, Gale is one of the killers this time around.
My money is on killer #2 being Jack Quaid, he just has that look and I'll trust my intuition. He'll turn out to be Gale's hidden half-brother or something and they're in cahoots.
As part of it being a "relaunch," Gale and Jack will have a kitchen confrontation scene with Sidney. How meta can you get?
