Della Rovere reaches France and strikes a bargain with its ruler to invade Italy and install him on the Papal throne in exchange for control of Naples; Rodrigo attempts to thwart the invasion through an alliance by marrying his youngest son Joffre to Princess Sancia of Naples (guest star Emmannuelle Chriqui), but Juan nearly sabotages the plan by seducing his prospective sister-in-law.
