Progressive elements appear prominently in subplots rather than the premise: Toni Topaz (introduced as a Southside Serpent) is explicitly bisexual, and her romance with Cheryl Blossom—known as Choni—features Cheryl coming out as lesbian, escaping conversion therapy at the Sisters of Quiet Mercy, and sharing a passionate kiss with Toni in episode 17 while anti-gay propaganda plays. Kevin Keller receives expanded storylines, including cruising in the woods amid the serial killer threat.

Creator Roberto Aguirre-Sacasa and writers emphasized adding more queer characters and intentional diversity, with Veronica cast as Latina (Camila Mendes) and Josie and the Pussycats as Black women. These elements influence character development and receive dedicated screen time but remain secondary to the crime and family drama plots. Audience and critic reactions note both praise for representation and critiques of sidelining or tokenism, without the ideology defining the season's core appeal or structure.
