With a holiday celebration around the corner, Bash uncovers what could be the answer to Francis finally escaping the oppressive thumb of Lord Narcisse, and the two formulate a daring plan. Meanwhile, Mary proposes the radical idea of marrying the Protestant Lord Condé (Sean Teale) to the Catholic Claude, a scheme that she believes a viable path forward to peace, but Claude has other plans in store. As preparations are made for the upcoming feast, Greer discovers that she may be more involved with the Protestant movement than she originally thought.

Mary takes action to save Condé when she learns the Vatican is hunting him for bearing the branded mark of the Dark Riders. Francis devises a plan to put an end to the Dark Riders legend, which puts Bash at risk. Meanwhile, Kenna reveals Catherine's ulterior motives to Claude.
