Print During her tenure as Dr. Cristina Yang on “Grey’s Anatomy,” Sandra Oh was the first to say one of the show’s most iconic lines: “You’re my person.” Cristina’s person — Dr. Meredith Grey (Ellen Pompeo) — spent much of the long-running medical drama’s 17th season in critical condition because of COVID-19. The unconscious Meredith shared time with a number of fan-favorite characters from “Grey’s” past on the beach of her dreams, including late husband Derek (Patrick Dempsey), late roommate George (T.R. Knight) and late sister Lexie (Chyler Leigh). This series of beloved guest stars — and the long wait for a Season 18 renewal, announced Monday by ABC, has prompted plenty of speculation about Oh’s possible return to the show for a highly anticipated Meredith-Cristina reunion.
