to donate bone marrow. Elizabeth fights with Henri, who drinks heavily and hides Paul's medication. Paul fears the blood test might reveal his father is not his biological parent. Henri refuses the test, because he never loved his mother. Faunia has agreed to visit before leaving for her own family. Her honesty and gentleness soothe Henri, and she stays for two days. On 23 December, Rosaimée visits for dinner and fireworks. She was Abel's mother's friend, although it is suggested that they were lesbian lovers. Rosaimée tells Sylvia that Simon stopped seeing Sylvia because he believed she would be happier with Ivan. Sylvia feels betrayed and manipulated. Henri has the test and discovers he can donate. He decides to do so despite disliking his mother. Simon begins drinking heavily in cafes, and the family seeks him. Sylvia discovers him and confesses that she knows he loves her. She and Simon spend several hours talking, then return to the house and make love. Paul tells Henri about his fears. Henri convinces him that he is not his father, confirmed by the test, and reassures Paul that it is not a failing to be afraid. They bond, and Paul’s mental condition improves. On Christmas Day, Abel and Elizabeth discuss Elizabeth's longstanding depression, and Abel reads her the prologue to Friedrich Nietzsche's On the Genealogy of Morality about how well we know – or don't know – ourselves. Abel suggests that Elizabeth fears death, and that has led to her caution and depression. The film ends with Ivan discovering his wife has had sex with Simon (they make no effort to hide it, waking up together in bed and greeting her children as they come bearing tea), but the effect on him is not revealed – he seems remarkably blase, as though he has expected it. Paul stays behind with Henri, who is having a positive effect on his mental health. Henri donates his bone marrow to Junon, but she announces, seemingly before medical evidence for it, that her body will reject the transplant. Elizabeth speculates that Junon will live, but Henri is shown flipping a coin in the hospital in front of his mother and not revealing the answer.
