In the evening Gustav goes to pick Gertrud up at the opera where she had said she would be, but can't find her. The next evening the Kannings attend a dinner party at the house of the poet Gabriel Lidman, with whom Gertrud has had a relationship in the past. Gertrud greets her friend Axel Nygren who attends the same party. Gustav confronts Gertrud about the opera, and demands one last night with her before the separation. Lidman tells Gertrud that he had met Jansson at a party where he had bragged about Gertrud as his latest conquest.
