Reign begins its third season with Mary and Francis realizing that they are more powerful together than apart, believing there is hope for them to move forward, leaving behind the anger and hurt. It also introduces us to another royal court, that of Elizabeth, "Virgin" Queen of England. Still early in her reign, Elizabeth faces opposition on all sides, particularly from men who doubt a woman's ability to rule. Like Mary, and Catherine de Medici, she struggles to hold onto power and love; the women have much in common, and Mary and Elizabeth are reluctant foes, but foes nonetheless, each positioned by birth and fate to destroy all the other holds dear.
