In London, Karin meets a woman named Sara and is surprised to hear Sara say she is David's sister, though he had told Karin he had no family. Sara guesses Karin is pregnant, though Karin refuses to say if the fetus is Andreas or David's. Sara also declares she and David will never separate. Karin leaves, saying she does not think she will return. Later, David and Karin meet in a greenhouse. David tells her he has found life without her intolerable, and that their relationship has changed him, and that he now cares about what happens to him. He says he has accepted a position at a university and asks Karin to come with him, with her children. Karin rejects the offer, citing her "duty" to remain. He accuses her of lying and cowardice as they separate.
