Paul McCrane makes his first appearance as the redoubtable Dr. Robert Romano, who in this episode has just returned from a European vacation, his head full of new information about robotics. Elsewhere, Carol (Julianna Margulies) wants to start up a free clinic in the ER. Del Amico (Maria Bello) is in for a surprise when she examines a male patient. After the deposition with the Law family, Greene (Anthony Edwards) demands to know if Chris Law (Joe Torry) had anything to do with beating him up. Jeanie (Gloria Reuben) and Al (Michael Beach) "mix it up" in a bar. And John Carter (Noah Wyle) wonders if he should have stayed in surgery after another doctor steals credit for one of Carter's ER procedures. ~ Hal Erickson, Rovi
