The ensemble includes multiple Black characters in prominent student roles such as Wes and Michaela without altering prior source material, alongside the ongoing gay romance between Connor Walsh and Oliver Hampton that features explicit LGBTQ+ storylines. These elements include detailed depictions of their relationship dynamics, such as breakups and reconciliations, explicit sex scenes, Oliver's HIV-positive diagnosis, and a season-ending proposal. Creator Peter Nowalk has expressed intent to foreground queer perspectives and diverse casting, stating pride in presenting a queer point of view and challenging stereotypes around HIV and gay sexuality.

While episodes incorporate cases involving domestic violence and criminal justice themes, these remain secondary to the core cover-up and mystery elements. The prominence of the LGBTQ+ arcs contributes directly to the season's ideological emphasis.
