Joy begins to open up with the doctor while the kids are dealing with a race against time at the contest. At the end of the competition, the professor starts giving her grades.

Marioni manages to reach Giacomo to tell him that he's sorry for how things turned out but also to encourage him to move on with his life. Matteo goes to talk to the new psychologist but puts up his defenses by saying that he doesn't talk much.

We are at the final competition, the dessert one, and both the Jams and The Best have a new captain. Joy talks to the doctor about how much she likes cooking but not so much drawing.

After Marioni assigns the orchestra parts to play with the guest conductor, there are some moments of tension between Matteo and Nathan. As a few students gather outside the conservatory, they see Giacomo, an ex-student.

Joy is not going to school and is not responding to anyone anymore. Melissa seems happy to know that the Jams will be in trouble at the competition, but the kids want to give it their all. Meanwhile, Joy is being helped by her parents.

The conservatory orchestra learns that the world-famous conductor, Ruggero Fiore, will be coming in just a few days to work with them and even give a public performance. With little time to prepare, Marioni asks for total commitment.

Alice returns home and is sad and very worried about Joy. She tries to tell her mother that Joy was left alone with the lawyer and that the story about the forgotten cake on the street was a lie. The mother then calls Joy's mom.

The kids continue to practice their instruments and go to lessons, but there's no shortage of love dramas and first kisses. Sara is dealing with her ex who just won't accept the breakup. And as before, she leans on Matteo.

At school, the teacher talks about bullying and after the lesson Alice tries to talk to Joy about what Max discovered. Joy doesn't react well and leaves her friend alone.

After Alice's surprise birthday party, she and Max share their monthiversary and want to tell about how they helped Joy.

Max and Alice are at the amusement park and want to go on a ride, but the place looks deserted. Everything is ready at the bistrot except for the cake, which Joy should be bringing. On the way to the party, she runs into her little friend on his bike.

For the finale, there will be an exceptional guest, a famous chef, and the kids are beside themselves with excitement. The Jams need to climb up the rankings, and Melissa's team changes their approach on how to manage the contest to win.

At school, Stefano has good news, but the lesson must continue. The teacher asks the students to observe outside and express what they see and feel through drawing. She is particularly struck by a couple of drawings, albeit for different reasons.

After Stefano returned with the Jams, things seem to have gone back to normal. Alice reflects on the fact that their age isn't an easy one because there are many changes. Some beautiful, others less so.

Joy finally realizes where Stefano might be and goes looking for him. She finds out what went wrong.
