Deliberate mistake: In the scene where Sam is swinging from the hospital window, you see him first from the inside. Now he is obviously being pushed (from a crew member) so it looks like he's moving back and forth smoothly. However, when seen from the outside he couldn't be pushed and so when swinging by himself, he was actually bouncing off the walls. Inside this would have been seen. Also, inside it seems that the sky is clear, though outside there is a tree by the window.

Joon: I lost.
Benny: What's in the pot?
Joon: A cousin.
Question: What exactly is wrong with Joon? I don't think they mentioned it in the movie, but does anyone have a good guess?
Answer: Initially, I thought that she had PTSD after her parents died because she appeared to have watched the accident or been in the accident.
Answer: She had schizophrenia, she showed that with her paranoia when she accused Benny of cheating and hallucinations when she was getting upset with the voices in her head on the bus.
Answer: I would guess high functioning autistic. Similar to Rainman. Especially her being obsessive compulsive.
