In this first episode of a two-part story, Ross' (George Clooney) maverick behavior catches up with him when his unauthorized treatment of ALD patient Ricky Abbott (Kyle Chambers) has fatal consequences. This tragedy has long-reaching consequences for others in the ER, beginning with the closing of Carol's (Julianna Margulies) free clinic. Elsewhere, former antagonists Carter (Noah Wyle) and Lucy (Kellie Martin) grow quite fond of one another; Benton (Eriq La Salle) all but depletes his bank account to pay for a sign-language tutor (Marlee Matlin) so that he can communicate with his son, Reese; and Nigerian janitor Mobelage (Djimon Hounsou) balks at telling his wife the real reason that he suffers from severe back pains and impotence. ~ Hal Erickson, Rovi
