Louis and Guillaume d'Orange engage in a merciless face-off. In a game of cat and mouse, they size each other up, study, and challenge one another. At the end of this formidable one-on-one, Louis finally emerges from the tiredness that paralysed him, and made him so dread his own creation, the Palace of Versailles. Imbued with a new energy, he returns to the Court, leaving his demons behind...but he is still unaware of Thomas' double dealing. At the Palace, shock reverberates around the death of Isabelle. Marie-Thérèse tries to persuade Fabien to resume his duties as Chief of Police. But Fabien, devastated by the death of Claudine, refuses her offer. Montespan feels more and more isolated, and starts to doubt the sincerity of her friend Scarron: could she too, also be in love with Louis? Complicity between Philippe and Palatine grows, leaving the Chevalier bitter and desperate.
