So should we figure out how each of the seasons happened? I know for season one the character Derek was just an occasional face to pop in to be one of the main bullies. Season two for Derek he shows up more and is in the list of main characters but more of a secondary main character that was the main one doing the bullying of the sophomores and freshmen. For third season he'd be a full on primary main character. Star of the football team and leader of the bullies at the school.
