Corrected entry: When the couch falls down the stairs, it hits Cynthia on the right side of her face, however in the library when you see her next, the bruise is on her left side.
Corrected entry: Each day Matthew has to create a new maintenance problem to be allowed into the Virgin Vault yet Crick has no reason to be there but he always is.
Correction: It is made clear that Crick abused/assaulted many of the women, so perhaps the majority of the girls are too afraid to tell him to leave.
Correction: You're right but she was sitting on a flight of stairs next to a wall when the couch came down the stairs. It likely hit her and smashed her face against the wall, thus the bruise being on the other side.
