Jimmy Borrelli

Former Firefighter Candidate/Paramedic Jimmy Borrelli (recurring previously; seasons 4–5). He was introduced in the season 4 premiere and a new candidate assigned to Truck 81. He briefly dates Jessica "Chilli" Chilton in the fourth season. He also briefly replaces her as a paramedic on Ambulance 61 after she is fired. After his brother dies in a burning building, he blames Chief Boden for a while and transfers back to Truck 81. He is critically injured by an explosion early in the fifth season, causing him to lose an eye and need round-the-clock care, thus ending his firefighting career.
