Scott's father starts playing chess with black which is not the way to start chess. First move must be made by white player.
The note Scott received in his locker stated for him to go to the pool Tuesday 9pm. Bess is then shown waiting at the pool and her phone states it is Monday.
Scott is messaging Jules outside her room, his text says "I found out...", when Jules gets the message, it says "I figured out...".
When Bess searches for Scott on her phone using Shadow Me, she types in "s-o-c-c-o-r" but the app auto-corrects it to "soccer".
