Nathan's (Don Cheadle) bedside manner -- or lack of same -- alienates him from his fellow doctors. Kovac's (Goran Visnjic) personal problems again spill over into his work. Abby (Maura Tierney) finds out that her missing brother, Eric, is in big trouble with the Air Force. And Weaver (Laura Innes) is on cloud nine after receiving some good news -- which she dares not reveal to anyone. ~ Hal Erickson, Rovi
