Although we don't see any flashback to the incident, Eugene tells a story of when he was sixteen and confronted his father who was abusive to his mother. He then states that his father hit him with a two by four, dragged him around the house, poured gasoline onto his body and then joyfully lit him on fire. Chris nearly runs over Trevor on his bike. Smuggled by some kids into school and later used during a scuffle to stab someone. Used by Sidney to get a nurse's attention to help a young girl who's suffering from an asthma attack.
Some kids smuggle a knife into school and around the security point metal detectors.
A minor bit of suspenseful music plays in the film. None that we heard, but a song playing in a club contained lyrics we couldn't completely understand, so there's the possibility something objectionable could have been in it. Arlene shows cleavage in various other outfits she wears. Chris jokes with a man who gave him his car and asks what if he picks up some hookers and drives down to Mexico with them. We see Arlene in her bra as she gets ready for a date.
