Sometime later, the mural is set on fire by a mystery arsonist, and everyone manages to get a look at the real one. Everyone in the school assumes Jack did it to get back at Skinner. While the police are out searching for Jack, Marge finds him hiding in the school playground. He swears to her that he did not start the fire. Marge believes him and distracts Skinner and Chief Wiggum so he can escape, but he instead sets fire to Skinner's car and dances around it laughing maniacally, revealing his true nature. Jack is arrested and Marge, furious that he lied to her face, demands Wiggum to take him back to prison.
