Butch Gilzean is the loyal right-hand man of Fish Mooney.
Growing up alongside fellow Falcone gang member Jimmy Saviano, Gilzean and Saviano were delinquents at an early age. One time, the pair robbed a butcher shop, stealing several pounds of meat for their families. Despite a brotherly relationship, Butch withheld several prime cuts from Saviano, leaving his partner-in-crime clueless that he had received the inferior ground beef. Disappointed with his choice later on, Gilzean kept his decision a secret for many years.
