After the climax, one major event that happenes to Radio is that his mom dies. He got extremly sad and tore up his house, because he doesn't know what to do without her. Another thing that happened, is that the school board tries to kick radio out of the school. Personally, I don't think it was fair, because there only reason was because he was developmentally delayed. Also, towards the end Johnny and Radio become friends. Some things that helped, are that radio gave Johnny a present, and also didn't tell on Johnny for the girls bathroom incident. This made Johnny realize that Radio wanted him as a friend and not a foe.
