Both know that the one to get the Jarjayes' on their side will be more popular, as Oscar is highly liked in court. Not wanting her mother to be caught in the vendetta, but ordered by the King to make a decision, Oscar decides to send her mother to be Antoinette's lady-in-waiting because a future queen's power would be more permanent than a courtesan's. Du Barry is enraged by this, and pesters the King until he gives the Dauphine a warning to improve her behavior...
