Matteo and his classmates, during the break, get together to root for Sara in the hope that she manages to convince Marioni to let her play with them in the orchestra. Rosario, on the other hand, is agitated, and it doesn't escape the notice of his friends or his percussion teacher.

Rosario chooses to avoid the encounter with his birth mother, so he makes up an excuse and returns to school. Meanwhile, at the orchestra rehearsal, Marioni puts Sara to the test, but she is determined not to give up.
