Grey's Anatomy may not have ended season 22 with the usual surprise twists - but doesn't mean more won't be coming soon. "We'll always have to wait to see who shows up in season 23," showrunner Meg Marinis told Deadline on Thursday, May 7. Marinis acknowledged that the season 22 finale had fewer cast members returning than usual, explaining that the choice wasn't intentional. "When we realized that we needed to exit two characters, we wanted to spend the most time on the characters that we have currently," she said.
