Antoinette sends her own invitation to Madame Jarjayes in order to counteract Du Barry's. 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. Meanwhile, Empress Maria Theresa sends Count Mercy to France as Antoinette's advisor. Mercy writes to the Empress about the Dauphine's struggle with Du Barry, who begins to worry about the alliance between France and Austria and orders Antoinette to talk to Du Barry. She ignores this order. Duke Orleans gives Du Barry a poison to use however she desires. She decides to stage an attempted poisoning and frame Antoinette and Madame Jarjayes as the culprits, but Oscar uncovers the plot and stops her with threats.
