The season prominently showcases LGBTQ+ representation through Callie Torres (bisexual Latina) and Arizona Robbins (lesbian), whose co-parenting of baby Sofia and ongoing relationship dynamics drive significant emotional arcs, normalizing same-sex family structures. Cristina Yang's early-season abortion decision is handled matter-of-factly, emphasizing reproductive autonomy and straining her marriage with Owen Hunt, a bold portrayal for 2011 that affects character development without heavy lecturing.

Meredith and Derek's interracial adoption of black baby Zola is a central plotline, complicated by custody battles tied to Meredith's professional misconduct, highlighting non-traditional family formation. These elements influence casting, character arcs, and plots but coexist with traditional medical crises, romances, and tragedies like the plane crash finale, without overt social justice monologues, systemic critiques, or source-material alterations. No significant contemporary backlash labeled it 'woke'; reception focused on drama and performances, with diversity feeling organic rather than forced or agenda-dominant.
