Cas and Poppy’s relationship develops quickly in tense, high-stakes circumstances; the couple rarely enjoys calm moments following their acquaintance. However, Poppy’s stasis forces Cas to reflect on his love for her, recognizing how he has adapted and evolved since the onset of their relationship. Taking the time to think about all he has gained as Poppy’s husband, Cas better understands himself, his strengths, and his weaknesses.

Poppy inspires Cas to be more forgiving; she insists on offering an opportunity for redemption, especially for those forced into their circumstances. When asked what to do with the Ascended while Poppy sleeps in stasis, Cas thinks, “Kill them. That [is] my first response. Make it quick and neat. But as I [brush] a smudge of dirt from Poppy’s hand, I [know] she wouldn’t want that” (48). Cas still recognizes the part of himself that is brutal and unforgiving. However, Cas yields to Poppy’s wishes, recognizing her abilities as an empath afford her a stronger moral compass. Without compromising the safety of his warriors and while demanding respect as King, Cas leads his people more gently with Poppy by his side.

Through his interactions with Poppy, Cas also grows to realize the significance of control over one’s life.
