Thursday marked the return of Sloan and Meredith’s half-sister Lexie Grey (Chyler Leigh). Mark and Lexie, who were a couple on the show, were in an aviation accident at the end of Season 8. While Mark was on life support at the start of Season 9, and did appear in some flashbacks, he passed away.
Meredith meets up with the pair on the same beach where she reunited with Patrick Dempsey’s Derek Shepherd and T.R. Knight’s George O’Malley.
A clip of the reunion was posted on Twitter, and Lexie tells her, “I love it here. It is so beautiful,” and asks Meredith, “Are you going to stay?” Grey isn’t sure, saying, “I don’t know the rules.”
