‘Grey’s Anatomy’ boss teases Dolly Parton impersonator episode in season 23

Variety’s Oct. 16 interview with showrunner Meg Marinis walks through the Season 23 premiere, “Collide,” which centers on a Sea-Tac collision that funnels trauma patients into Grey Sloan Memorial just as the hospital unveils its new VIP floor.

Marinis reveals that Episode 3, already in production, features a Dolly Parton impersonator patient, a story idea credited to writer Jase Miles-Perez and filmed before Parton’s passing.

She also confirms the untitled West Texas spin-off remains in active development with Shonda Rhimes, echoing the same details previously reported.

Marinis addresses the recurring speculation that Season 23 could mark the series finale, noting the industry-wide budget environment but offering no confirmation or denial.

The premiere introduces James Wolk as Seth Norton, the physician-turned-executive overseeing the VIP initiative and serving as the new chief of surgery.
