Moody starting his 'protection' thing
When the movie begins, they are sophomores. So, was Moody already doing his "protection" thing as a freshman? Did he only bully other freshman at first, then the next year the sophomores (from the previous year) and other freshman? Surely there were older kids that could have easily stood up to him.
And when did he start? Did what happened with Linderman's brother give him the idea? Or was he doing it before that?
