There was a teacher on scene, who had gone to tell the principal about the bully. He told the other kids to not misbehave
So, the student who said the world doesn’t revolve around the bully is the quiet kid, so he said it politely so that he doesn’t get in trouble. Clever kid.
The quiet kid’s friend is the popular kid, who announces that he agrees with the quiet kid because the other kids believe what the popular kid says as he’s a trustworthy person. A nice guy to talk to when you’re in a bind.
And the bully is absolutely speechless, then starts yelling all sorts of racial slurs at the two friends, but then the class clown arrives with the teacher and the principal, who reprimand the bully for bullying and offensive language by giving him a week’s worth of detention.
