The end of Season 3 left our Killjoys scattered to the far corners of The J galaxy and beyond. Dutch is on a journey to face her biggest foe yet, while D’av and John are trapped in an elevator in deep space with a pregnant Delle Seyah. They are united by the knowledge of the name of their true enemy: The Lady, an immeasurable manifestation of evil without beginning or end. The Lady is making her play, and our trio has something she wants.
