Upon his return from camp, Bart finds his mother has left and movers are removing her belongings. He angrily confronts his father, who denies that his abusiveness was the reason she left. Years later, in high school, Bart and Shannon are dating. Bart plays football to please his father but is injured, breaking both ankles and ending his career.
