It looks like Grey’s Anatomy has bled its final drop of “Grey” DNA. Ellen Pompeo, who had anchored the series since 2005, had her last episode as a series regular in February, and now, Kelly McCreary—who for nine seasons has played Meredith’s half-sister, Maggie Pierce—has announced that she’ll exit the ABC medical drama in April. Barring a sudden reveal that someone like Schmitt has been Meredith’s long-lost cousin all along, she was Meredith’s final living, biological relative on the series. (Although, at this point, Meredith and her sister-in-law, Amelia Shepherd, might as well also be blood.) McCreary told The Hollywood Reporter in a statement: “It has been a tremendous honor to be a part of such a legendary television institution as Grey’s Anatomy. ... Playing Maggie Pierce has been one of the true joys of my life and I leave with profound gratitude for every step of this journey. I am excited for this next chapter, and what the future holds.”
