Kelly McCreary, who started playing Meredith's half-sister Maggie in season 11, was kind enough to share some insight about season 13 with TV Guide, mainly that Rhimes wants it to heavily follow the original cast members: Meredith, Alex, Bailey, and Richard Webber. "After such a long period of time and so many new people coming in and out, they remain the foundational characters of the show," she said. "We're gonna be spending some more time with them to check in with where they are. The way that we spent time with Meredith last season, exploring the major shift in her life, the loss of Derek, I think we can expect to see those doctors being explored where they are in this moment, all these years later, the changes that they've gone through."
