The main character has relatively old burn scars along the right sides of his back and chest, and on his right shoulder.
A teenage boy punches another teenage boy to the floor, and uses his fist to repeatedly pound the other teenage boy's face. The victim's nose is broken, and blood flows from it.
A teenage boy beats up another teenage boy, kicking him while the he is down. The altercation leads to the victim being taken to the hospital, with bruises forming on his forehead and around his eyes.
A man slaps a teenage boy around, forcing him to his knees, before unzipping his own pants (suggestive of preparation for reception of coerced fellatio or for some kind of urination humiliation, but we have no way to know whether it is a new behavior or part of a pattern of behaviors).
In a physical altercation, a gas can is knocked over and some gasoline splashes on the two involved. One of the two lights up a signal flare and tosses it at his opponent, setting him and much of the site of the struggle ablaze, and getting burned himself.
A teenage boy briefly uses his hand to forcibly hold another teenage boy's mouth and nostrils closed, after the other boy has inhaled some drug smoke.
