Sean Renard

Anna Shade:
She is not a Hexenbiest. She is Adalind's fully human half-sister (through their monarch father), who grew up with her in Europe during childhood, though their paths eventually diverged. Anna is the former fiancée (or long-term partner) of Eric Renard, Sean's younger brother. Their relationship was serious, and her breakup with Eric occurred shortly before his death. She knew about the Wesen, knew the true nature of the Renard family (that they are Zauberbiests), and was aware of Eric's dark dealings, which ultimately led to their separation. She is intelligent, perceptive, possesses a will of steel, and harbors a deep, long-standing dislike for the Renard family—especially Sean, whom she holds responsible for Eric's corruption and demise. She works in international law or crisis management—a profession requiring composure and an analytical mind.

Years after the finale, while picking up his daughter Diana, Sean crosses paths with Anna Shade—Adalind's human half-sister and the former fiancée of his late brother, Eric. She knows about the Wesen and hates the Renards, believing Sean to be guilty of Eric's death.

Her icy contempt and fearlessness challenge Sean. He begins to "pursue" her like dangerous territory: appearing "by chance" and engaging in caustic dialogues. Her intellect and principles (having left Eric once she saw his true nature) intrigue Sean—she is a living reminder of a path he did not choose.

When Eric's avenger attacks them both, Sean reveals his nature while protecting Anna. In their forced proximity, their enmity evolves into a harsh, mutual understanding.

In the finale, Sean declares to her not as a romantic, but as a ruler: "You are a challenge that I accept. You will stay. I want this." Anna, accepting the challenge, throws the gauntlet back at him: "Try and stop me." A game has begun, where the stake is not power, but personal happiness.
