Sandra Oh changes her response about potentially returning to Grey’s Anatomy. For ten seasons, Oh played Cristina Yang in the long-running medical drama. However, her departure was announced in 2013, and season 10, episode 24, “Fear (Of the Unknown),” which aired in 2014, marked Cristina’s last episode. The star has been vocal about not wanting to return to the series, though her character still exists canonically in the franchise.
