Mary Cosby

Mary Cosby is back full time with her fiery remarks and 2003 Dom Perignon. Mary re-immerses herself in the group, making amends with Whitney and Heather after her name calling, and a deep and unexpected friendship develops with Angie. Although she has a new ally and confidant, Mary and Meredith’s longstanding friendship is on thin ice as they struggle to see eye-to-eye.
