On a Saturday night, a few weeks after Robert and Adele's conversation, the main house is fully illuminated and adorned, and all the guests are present to unwind and enjoy themselves. The kids are even allowed to stay up late, until they are served ice cream and cake. An impromptu music recital begins, and the Farival twins play piano pieces, a young girl performs a dance, and a brother and sister recite literature. Afterwards, everyone dances while Adele plays the piano.

As Adele performs, Edna envisions a desolate scene where a nude man stands by himself on the shore and observes a bird plummet from the sky.

Robert departs to bring Mademoiselle Reisz, who agrees to play the piano, pleasing everyone. Edna has a strong affection for music, as it typically conjures up mental images when played well. However, on this occasion, the music does not produce any images for her. Rather, it evokes intense emotions, causing her to tremble and weep. Mademoiselle Reisz concludes her performance and departs, content with Edna's reaction.

Soon after Mademoiselle Reisz departs, the party ends, but several attendees opt to follow Robert's recommendation to take a night swim.
