In this Emmy-winning concluding episode of a two-part story, Ross (George Clooney) suffers the consequences for his part in the death of ALD patient Ricky Abbott. Also detrimentally affected are Carol (Julianna Margulies) , who assisted Ross in treating Ricky, and his superiors Greene (Anthony Edwards) and Weaver (Laura Innes). Weighed down by controversy and not wishing to cause any more trouble for his colleagues, Ross bids farewell to County General. In other developments, Greene treats injuries stemming from a school bus accident; tragedy strikes in the home of troubled Nigerian janitor Mobalage (Djimon Hounsou); and Carol makes a painful personal sacrifice to save her free clinic. ~ Hal Erickson, Rovi
