Giangrazio's brother, Lamberto is now dead and has left behind a daughter, Elisa, and a step-daughter, Faustina.
Don Marciello must obey his father and marry Faustina, but is in love with Zeza.
Don Marciello reflects on his unrequited love for Zeza and his unwanted marriage to Faustina.
Giangrazio complains about the wasted education of Don Marciello, who prefers to spend his life in pleasure and refuses to marry Faustina.
This arouses Meo's jealousy, and shortly afterwards he makes Zeza feel his suspicion.
She finds Don Marcellio's advances annoying, and she feels neglected by Meo.
In front of the inn, Don Marciello approaches Zeza again and asks for wine.
Luigi is astonished that Zeza seems to have given up Meo so quickly in favour of Don Marciello.
His joy at the fact that Faustina is now free for him is, however, interrupted by Elisa, who is still hoping that he will return her love.
When Meo cynically asks Zeza if she has any admirers besides the father and son, she recognizes Giangrazio's infatuation.
Then Don Marciello and Meo start a loud game (a morra) to annoy her.
Neither Giangrazio nor Don Marciello want to admit to each other that they are in love with Zeza and ask her to confirm her innocence.
Elisa confesses to Faustina the reason for her anger: her unrequited love for Ascanio.
Giangrazio offers Ascanio to rehire him if he ensures that Don Marciello and Faustina marry that very evening.
Meo watches from a hiding place as Don Marciello courts Zeza again.
Giangrazio recognizes from this that Ascanio is his second son Alidoro, who was believed lost and whom his mother had named after this mark ("ali d'oro" - "golden wings").
When Don Marciello returns to continue the fight with Ascanio, Giangrazio introduces him as his brother.
Alidoro admits to having worked as Ascanio's servant only for appearances' sake in order to be close to his beloved Faustina.
As a child, after being lost on the beach in Genoa, he was raised by a Genoese man under the name of Luigi.
At the request of Don Marcello, Giangrazio gives his blessing to Alidoro and Faustina.
