Enrico is an Italian foreign exchange student, who stays with the Fowler family in 1999. He makes a big impression on Sonia Jackson, particularly when she discovers that he is a fellow trumpet player with a penchant for jazz music. However, he also receives a lot of unwanted attention from Sonia's friend, Nicky di Marco, which causes several arguments.
Sonia is sure that Enrico prefers Nicky and so she shuns him when he asks her on a date. Nicky eventually grows tired of Enrico constantly talking about Sonia, so she tells him to tell her how he feels. He does, and Sonia is overjoyed. However their romance is short-lived, as Enrico returns home to Italy the following day, but not before he takes her for a romantic meal and a dance at Giuseppe's Italian restaurant. They share a kiss, and Sonia confesses that it had been her first.
