The wedding of Carol Hathaway (Julianna Margulies) and John Taglieri (Rick Rossovich) is complicated by the fact that bridesmaid Susan Lewis (Sherry Stringfield) is called away to care for the baby of her missing sister, Chloe (Kathleen Wilhoite). This minor crisis, however, is supplanted by a major one when Taglieri seemingly disappears from the face of the earth. And back at the ER, Carter (Noah Wyle) celebrates his last day at County General with some harsh words aimed at Benton (Eriq La Salle) -- words that Carter is forced to eat after a sudden change in the scheme of things. This was the final episode of ER's first season. ~ Hal Erickson, Rovi
