Marioni has an intimate moment with Irene and lets her know how important she is to him, whispering the lyrics to "Senza fine" by Gino Paoli. At the conservatory, the orchestra is ready to go onstage for the concert, where, presumably, everyone will play from memory. Matteo's uncle and friend are in the audience, but Nathan hasn't invited anyone. Sara is nervous.

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.
