Signora Crosetti was the wife of Filippo Crosetti and the mother of Annarita Crosetti. She knew of her daughter's efforts to return Eduardo Caruso to his own home timeline. She was also aware early on that Annarita was developing a romantic relationship with Gianfranco Mazzilli, the son of their flatmates. Initially, Senora Crosetti wasn't enthusiastic, as Gianfranco was not a good student. However, Gianfranco grew progressively more studious. Like her husband and daughter, Signora Crosetti waited on pins and needles until Gianfranco returned home after Eduardo Caruso "kidnapped" him.
