Villanelle is explicitly bisexual, sleeping with both men and women while fixating on Eve, and the season advances their romantic tension without resolving it into a conventional relationship. This prominent queer element shapes character motivations and subplots but remains embedded in a stylized thriller premise rather than serving as overt identity-politics messaging or systemic critiques. The season features a female-led production team and casts Sandra Oh as Eve Polastri in a role that does not involve a race swap from the source material.

The central homoerotic tension and bisexual portrayal of Villanelle serve as the core emotional driver, highlighted by the kiss and explicit romantic acknowledgment between the female leads. These elements contribute to the thematic focus without dominating the thriller aspects or introducing broader ideological critiques.
