Determined to get rid of the conductor whom he believes responsible for the death of the oboist, the director takes advantage of the fall in the middle of Barizet's concert to replace her. The musicians threaten to go on strike and demand her immediate return. Although Yvan and his son Mattéo Borowski, who became assistant conductor, turn out to be unexpected allies, the presence of Hélène exacerbates the tensions within the orchestra. Crozes then demands that she return to live with him or risk withdrawing his funding from the Philharmonia. Exhausted, the Maestro gives up. Convinced of being dangerous to those around her, like her own mother, shattered by Huntington's disease, Hélène decided to return to New York, abandoning Selena and the orchestra. Her father, Jean Barizet, then reveals the truth about her condition to her.
