Enter Mr. Gesualdi. The St. Bernadine's teacher is introduced early on in the season as the man responsible for getting a student named Grayson Wentz expelled the previous year because Grayson harassed a classmate on Twitter using one of the computers in the school's computer lab. It's revealed that Mr. Gesualdi was also catfished by the Brooke Wheeler persona, to the point where he sent her nude photos of himself. The Turd Burglar used those photos to get Mr. Gesualdi to switch out the chocolate in the teacher's lounge advent calendar, not Lou.
