Plot hole: When John arrives at Diana's crash scene, he has no reason to believe that she was involved in the accident. He doesn't know what she was driving. He would have just assumed it was someone else and kept driving through. But instead, he gets out of his car and asks where the children are, just assuming it was Diana there, for no logical reason.

Revealing mistake: When Diana and John first enter the mobile home, there's a shot of a TV with a dented screen. It's very obviously an old CRT, but cathode ray tubes can't be dented - they're made of glass, and would not only crack and break, but would implode, since they contain a high vacuum inside. This is obviously a prop TV that has been "distressed" simply to make it look old. (01:09:01)

Deliberate mistake: John is shown repeatedly studying Lucinda's numbers and even copies them to a whiteboard, and yet when Diana notices the backwards EE at the end, he's surprised and obviously acts as though he hadn't noticed them before, straining credulity, since he had just as obviously obsessed over the numbers and couldn't have missed the letters beforehand.
