Omar returns and navigates his relationship with Joel, who develops feelings for Iván, leading to an affair, Omar catching them in an awkward situation, Iván making a last-minute proposal to Joel, and ongoing confusion that fractures the couple. These plots occupy significant screen time across episodes 4, 5, 7, and 8.

Nico, a transgender male character who has undergone gender affirmation surgery, continues his arc involving relationships and identity acceptance. The season poster prominently features a male-presenting character with black nail polish, earrings, and rings in an intimate kiss, visually foregrounding non-traditional gender expression and same-sex romance. While the overarching premise remains elite-school murder mystery, class tensions, and family crime, the queer elements are not incidental but actively shape character decisions, emotional cores, and subplots in ways that go beyond organic diversity.
