Other mistake: When Daniel is playing Guitar Hero with his friends, after he and his friends leave the game to go outside, if you look closely at the TV, you can see that the game is still playing (notes are still being strummed) even though there is no one at the controls. (00:23:05)
Other mistake: When Esther comes into the living room to attempt to seduce John, he is drunk and the first few shots of her are blurred as though it was from his point of view. The problem is that the camera is a couple of feet from the couch. From where John is sitting, the point of view shown in the blurry shots is impossible. (01:35:45)
Answer: The boarding school was going by the falsified records that Esther had with her. They did not suspect anything, so they had no reason to dig any further at the time.
