Derek, Meredith and her unstable uterus take center stage in the latest sneak preview clip from tomorrow night's Grey's Anatomy fall finale, with the couple hoping to see their baby's heartbeat for the first time.
In one of the previous Grey's Anatomy clips from the episode, Derek's sister Lizzie chastised Meredith for keeping his family at arm's length. Here, he asks Meredith if he can tell Lizzie they're expecting.
Mer's hesitant, but at least she's consistent. She hasn't even told Cristina yet, much to Derek's surprise. Before they can debate the matter further, it's time for the sonogram and the moment of truth.
