When Jerome was little, his uncle Zachary put his hand in a pot of boiling chicken stock because Jerome tried to steal a snickerdoodle. Years later, Jerome pays his uncle a visit at his diner after his breakout from Arkham Asylum. Zachary prepared three different soups where one was for himself, one was for Jerome, and one was for Lunkhead who showed up to help. When Bruce Wayne showed up to confront Jerome, Lunkhead attacked as Jerome tried to get Zachary to ingest bleach. Though Zachary got out of it by writing down the address for St. Ignatius, Jerome still killed him. Zachary's written address would later be used by Bruce when he calls up Jim Gordon.
