Grey's Anatomy Scoop: Kelly McCreary Promoted to Series Regular

Grey's Anatomy Season 11 Maggie

Meredith’s new sis is staying put.

Grey’s Anatomy has promoted Kelly McCreary (AKA Mer’s surprise half-sib Maggie Pierce) to a full-fledged series regular, TVLine has learned.

McCreary joined ABC’s medical soap at the end of Season 10, when Maggie was hired at Grey Sloan Memorial as the head of cardiothoracic surgery. Her icy relationship with Mer began to thaw considerably in Thursday’s episode, as the sisters bonded over mother’s journal.
