Meanwhile, Rémy is reunited with his friends, including Pierre, Dominique, Claude and Diane, Nathalie's mother, and they share a conversation on their old sex drive and the gradual decline of their vitality. Diane is concerned for Nathalie, while Rémy, a history professor, lectures the hospital chaplain Constance on the relative peace of the 20th century compared to past centuries. At the same time, another scholar describes the September 11 attacks as historically small except as a possible beginning of modern barbarian invasions. After Rémy and his friends retreat to the countryside, they speak of their devotion to constantly evolving -isms. Rémy dies in the company of his friends and Sébastien, after a heroin injection from Nathalie, whom Rémy calls his guardian angel.
