In an Instagram Stories Q&A last month, the Grey's Anatomy creator responded to a question about Ramirez's return as Callie Torres, saying: “Let me tell you something — we tried. CBS has a hold of her. Because she’s on (Madam Secretary) And we can’t get her. But we love her. Always. This is her home. Come home Callie.” Ramirez responded today, tweeting: "For the record @CBS has been nothing but gracious and generous to me. They are open to Callie coming back! The ball is in @ABCNetwork‘s court."
