Rotten to the Cor-y?

‘th hell happened to Cory? Early in Act III, he really had the potential to be an interesting character: son of an alcoholic/workaholic father who had no time for him, Cory was by turns a thief, a vandal, and a test cheat. Readers still wonder what went on at the New Year’s Eve party he threw while his parents treated themselves to a Caribbean vacation. Nowadays, his sole purpose is to serve as a wisecracking foil to his hapless teachers. Maybe that experience wearing the pizza costume succeeded in finally breaking his rebellious spirit.
