Having missed a bone tumor on a child's x-ray, Ross (George Clooney) is none too anxious to tell the patient's grandfather (Bill Cobbs) about the mistake -- especially since four months have elapsed and the tumor has gotten worse. Meanwhile, Chloe (Kathleen Wilhoite) sweeps back into Lewis' (Sherry Stringfield) life, insisting upon full custody of little Suzy. Carter (Noah Wyle) worries himself into a stomach ache over his much-anticipated residency at County General. And Greene (Anthony Edwards), newly shed of his marital status, radically changes his image. ~ Hal Erickson, Rovi
