Rebecca continues to try and get Sean to sleep in the house with her, as she begins to wear Cathy out planning parties and focusing on other things than her cancer. A spot opens up in Dr. Sherman's trial though Cathy is saddened to learn its only opened because a woman died, shaking her confidence in Dr. Sherman. Cathy returns to work to discover everyone knows of her condition, making her feel awkward though Andrea treats her with the same rudeness Cathy likes. She throws a baby shower for Rebecca, she and Sean make up, and Cathy regains her belief that Dr. Sherman's trial can help.
