As the enraged Pietro rushes off to confront Mendoza, Malevole meets with his friend Celso. It is revealed that Malevole is, in fact, Altofronto, the former Duke of Genoa, deposed in a political coup staged by Mendoza on behalf of Pietro, made powerful through an alliance with Florence solidified by his marriage to Aurelia. Malevole, with the help of his spy Celso, has been learning the strengths, weaknesses, and secrets of his enemies, biding his time in the usurper's court until the opportune moment to strike presents itself. While Malevole schemes in Genoa, his wife Maria has been imprisoned, faithfully awaiting his return.
