If Grey’s Anatomy fans expected a warm sisterly embrace between Meredith (Ellen Pompeo) and Maggie (Kelly McCreary) when the ABC medical drama returned for season 11, they were sorely mistaken. Instead, the unaware Meredith butted heads with the new head of cardio, ultimately leading to a nasty confrontation that will undoubtedly color Meredith’s reaction when she eventually finds out the truth that Maggie is her half-sister.
“It’s going to get worse before it gets better,” McCreary tells EW. “Maggie’s a professional, but they push each other’s buttons professionally. They have different approaches on how to do things. Try as Maggie might, she can’t release her stubbornness or other vices, like her tenaciousness, when it comes to working with Meredith.”
