Puglia, how wonderful! / Yes, sometimes they come back

While the entire Martini family is on vacation in Puglia, a mysterious man leaves an envelope addressed to Elena, Lele's late first wife, in the mailbox of the Poggio Fiorito villa. Valerio, Elena's former piano teacher, under the pretext of a rap concert, tries to get to know Anna and seems overly interested in the affairs of the Martini household. Meanwhile, Sara, without consulting Lorenzo, signs the preliminary agreement for the purchase of a villa.
