Weaver (Laura Innes) treats a six-week-old infant who isn't thriving as it should. Already unnerved by the news about her brother Eric, Abby (Maura Tierney) must also deal with an overmedicated -- and extremely violent -- patient (Johnny Sneed). And Dr. Gordana Horvat (Nina Sablich) a friend of Kovac (Goran Visnjic), and a fellow Croatian, supervises the surgery on a boy with a congenital heart problem. Frances Sternhagen makes her final appearance as Millicent Carter. ~ Hal Erickson, Rovi
