Oscar, at the Duel at Dawn Episode 12

Antoinette is easily swayed by Beltin Dressmakers into spending an extravagant amount of money on their finery. She spends more time entertaining herself than attending to her duties as Queen. Despite her earlier worries, Oscar decides to let Antoinette do what she wants because she senses that Fersen's leaving has left her very lonely. Guemenee and Orleans try to manipulate the King and Queen into canceling audiences with peasants, but Oscar advises Antoinette against this, and she listens. Oscar and Guemenee get into a fight over each other's behavior, so Guemenee challenges her to a duel. Orleans and Guemenee decide to hold the duel in a place where Oscar would be temporarily blinded by the rising sun at a crucial moment.
