There is a persecution scene, implying a guy wants to fight with the main character but nothing graphic is shown because he gets saved.
At the ending, a guy invites the main character to fight at the party, people are excited and encourage them to do it. Nothing really violent is shown because a friend of the protagonist saves him before anything happens to him
It is implied that one of the movie characters is very dangerous and somebody "You should not mess around with". Presumably, he's related to drug dealers, but this is absolutely not explicit because it's just a supposition
At one of the main character friends Sub-Plot it is implied he was atacked in the face with tacks, this is meant to be a joke
