Sara goes to talk to Gigi, who is playing his guitar and singing on the street. When Robbo returns home, he finds Chiara upset, who tells him she's gotten into trouble. Barbara, on the other hand, has to face Marioni again at the orchestra rehearsal.

During the concert rehearsals, Marioni believes that Barbara hasn't put in enough effort because she has dedicated time to studying philosophy. He therefore decides to exclude her and warns the others not to console her.

Alice and her friends know that something serious has happened to Joy, but their parents have only told them to be patient and that their friend will return soon.

Matteo and his uncle Daniele seem to be very similar in some ways, but perhaps Matteo shouldn't be copying his uncle in every way. Scheggia and Sofia go to eat at their mother's restaurant and tease her a bit.

The finals are approaching and Alice, Stefano, and Max record a video of the recipe they have chosen as an appetizer to send to Joy. The JAMS don't want Joy to feel alone and wonder what point there is of participating in the final competition without their friend.

Matteo meets Sofia to whom he confesses being excited about the concert. At Sara's house, Gigi plays for her parents the song he composed for her. Robbo and Chiara unfortunately witness an argument between their parents.

The JAMS are a group of four and without Joy the finales make no sense. Alice, Stefano, and Max go to visit Joy to show her just how important their friendship is and to let her taste the cake they made.

The JAMS arrive at school in a rush, where the awards ceremony is already underway. Chef Borghese has just awarded the trophy but asks the winners if they would rather win by challenging the JAMS. Oscar, as captain, decides to continue the competition and they begin.

Marioni is summoned by the principal because he received a warning from Giacomo's parents who hold him responsible for what happened to their son. During rehearsals, the maestro discovers someone who shouldn't be in the hall.
