He sells Guido a robe and offers the prince everything that he has in his house; Guido chooses Bianca. Simone takes Bianca to her room and asks her to spin, which she refuses to do. After he leaves, Bianca declares that she hates her husband and wishes him dead. Overhearing this, Simone reflects further on adultery and death. He leaves Guido and Bianca alone together and the two lovers express their devotion. When Guido is about to go home, Simone challenges him to a fight, first with swords, then with daggers, before Simone finally overcomes Guido and strangles him. Bianca, admiring her husband's strength, rushes to embrace him and the two are reconciled as the curtain falls.
