Morton is a freshman, yet he is seen in a few strips with Peter, who is a junior. It can't be that Morton has skipped two grades, because Morton is seen in gym with Peter, and we all know there's no way Morton skipped two grades in gym. Once, Peter was paired up with Morton for a science lab and Peter was lured into going to Morton's house when Morton "understood that you're popular, but I'm just a lowly freshman who gets straight A++s."
