I'm surprised to see a Vivarium reference here. Though it's the kinda horror movie that doesn't scare me cuz all I think is "ok. I won't go to that location" and I'll be fine.
Why isn't her mom picking her up? She is monitored with a gps app on her phone. Also if her mom finds out that her daughter shared a bed with the dude, she will be home schooled from there on out.
