Teri Garr guest stars as patient Celinda Randlett, who claims to possess the incredible power of seeing "inside" people. In other developments, everyone in the ER finds out that Carol (Julianna Margulies) is pregnant with twins; Weaver (Laura Innes) brings in an abandoned child; Benton (Eriq La Salle) gets more bad news; a teenager (Corey Parker Robinson) whom Carter (Noah Wyle) previously mentored returns as a patient; and Lucy (Kellie Martin) is becoming more and more dependent upon Ritalin. Two romances -- one new, one renewed -- cap this episode, the last of ER's fifth season. ~ Hal Erickson, Rovi
