In Kiss of the Basilisk, Tem, Caspen, and Leo enact tension between personal desire and the obligations laid on them by their societies. Their choices carry political and emotional consequences. The stakes are heightened because all of them are extremely powerful: Caspen and Leo are both princes and the likely heirs to their respective kingdoms, while Tem is a rare hybreed who possesses immense magical powers due to her dual nature. As each character moves through this conflict, the novel shows that integrity grows out of decisions shaped by a personal moral code rather than unquestioned loyalty to kings or customs.

Tem’s character arc begins under the weight of duty. She participates in the competition because she wants to support her mother and escape poverty. That obligation soon collides with her deepening bond with Caspen. Her greatest test arrives when she must decide between her desire for Caspen and a marriage to Leo that could avert a devastating war. Later, Tem is also torn over a choice of whether to perform the crest at the wedding since one of her lovers will die as a result. Finally, Tem must decide how to manage the immense power she wields over Leo after cresting him. In all these cases, Tem finds a middle way that reflects her personal values of non-violence, empathy, and collective care. She is able, for example, to crest herself rather than sentence either Leo or Caspen to death. She sends Leo in pursuit of Evelyn as a gentle way of avoiding coercion and in hopes that he will be able to experience love and fulfillment. She makes her own decisions, departing from established social scripts that emphasize binary choices.

As the son of the basilisk king, Caspen is expected to obey Bastian and serve his quiver. His love for Tem, however, leads him to push back against Bastian’s orders. Caspen refuses to treat Tem as a tool for political gain and shields her from threats inside the basilisk community. He is always also insistent on Tem’s agency; for example, he repeatedly tells her that she does not have to undergo the ritual for his sake. Caspen’s personal desire for Tem makes him ferociously protective of her and he repeatedly acts in protective ways, even when doing so causes risk and discord for the basilisk community. For example, he kills the men who assaulted her (deepening the rift between basilisks and humans) and mutilates Rowe, stoking the feud between the clans. Most strikingly, when Bastian attacks Tem, Caspen kills his own father to save her. This moment rejects filial and royal duty in favor of a profound bond of love. Caspen and Tem become the rulers of basilisk society because they make their own choices and assert their own power.

Finally, Leo pursues his own journey turns toward freedom from his violent inheritance. Raised in a monarchy that thrives on bloodletting, he initially reflects the privilege of his position. His relationship with Tem and his growing knowledge of his family’s cruelty force Leo to confront the corruption he stands to inherit. Once he becomes king, he orders the release of the imprisoned basilisks and dismantles the foundation of his family’s power. In choosing justice over tradition, Leo shows that duty can evolve when a character uses it to confront the wrongs passed down to him. Leo’s choice of Tem as his bride, in defiance of his father’s wishes, further highlights his willingness to make decisions based on love rather than familial and societal obligation. While many of these decisions are painful, all of the characters are liberated and empowered when they make choices that align with their personal values rather than acting according to social expectations.
