What the...(spoilers)

After Justin's mom drops her son off at the end, his girlfriend leaves him outside after talking to him for just a few minutes? What about the ending? We don't see what happens to the bullies. We also don't know if he goes back to the swim team.

There are so many things that didn't make sense. No one is concerned that one of the girls strips on camera even if the whole school knows about it(including the bullies who were trying to protect her at the end). Justin's mom also doesn't seem too concerned when she catches him lying about where he was. At that point, I would assume that there was something more dangerous than internet porn going on. This movie just failed on so many levels.
