Once, when asked by Fiora Cavazza about his business, he slapped her, and slapped Lucia when she tried to defend her in turn. He forced the courtesans to silence, threatening them with a dagger, despite them having learned so little from his escapade. Afterward, he told the courtesans that he would tell his sister of their cooperation, then left. Later that same year, Santino was beaten by Cesare Borgia for interfering in trades that he and his sister had no right to. In exchange for their lives, Madonna Solari and Santino allowed Cesare to pick one of their courtesans to work for him.
