Nunzio was a co-worker of Topanga and Angela's at a restaurant in Last Tango in Philly. He, Angela, Topanga, and Sergio went dancing one night, and Topanga described him as a great dancer. Cory and Shawn became jealous of Nunzio and Sergio, and remained suspicious of them and their girlfriends. Cory eventually forbade Topanga from seeing him again, though she had to anyway because of her job. Nunzio later taught Cory how to dance for Topanga, and was aware of the guys' plans to dance for their women at the club.
