Meredith Grey is back! On the ‘Grey’s Anatomy’ season 19 finale, the doctors of Grey Sloan fly out to Boston, where Meredith now lives, to attend the Catherine Fox Awards. During their visit, Meredith shares a new theory on Alzheimer’s that she wants to present to the board, but she doesn’t have the full support of her old colleagues. Meanwhile, there’s some resolution in Meredith’s love life, as she and Dr. Nick Marsh admit how they truly feel about each other. Previously, Meredith left him hanging when he said ‘I love you,’ before she left for Boston.
