Mel Vera is explicitly written as a lesbian feminist activist and women's studies student whose relationships with women (including ongoing arcs with Ruby) and social justice focus form a core part of her identity and screen time. Creators Jennie Snyder Urman and team intentionally shifted from the original's three white straight sisters to a diverse cast of women of color as new characters, citing a desire to reflect 2018 realities, provide representation for POC and LGBT audiences, and address patriarchy and current politics alongside demon-fighting. In season 3 specifically, the introduction of cousin Joséfina Reyes—a trans woman played by out trans actress Mareya Salazar—centers an arc on her identity, family rejection tied to beliefs about 'biological women' and magic, and eventual power manifestation, adding explicit gender-identity normalization.

Additional elements include Mel teaching on intersectionality and allyship with a trans male student. These choices make identity, diversity, and feminist framing central to character appeal and narrative texture rather than incidental. While the core premise remains supernatural sisterhood battling evil, the ideological elements drive casting decisions, character definitions, and specific season 3 storylines, elevating the score.
