Pomerantz (Jami Gertz) refuses to put a woman with Down's syndrome on a heart-transplant list; Greene (Anthony Edwards) and Doyle (Jorja Fox) try to persuade her to change her mind. Now that he is of legal age, Jad Houston (Chad Lindberg), suffering from terminal cystic fibrosis, insists upon being taken off life support -- but Jad's mother (Veronica Cartwright) won't hear of it, forcing Ross (George Clooney) to act as "mediator" between life and death. And the relationship between Jeanie (Gloria Reuben) and Fischer (Harry J. Lennix) becomes more serious. ~ Hal Erickson, Rovi
