Sopranos fans are attempting to analyze this today: Did Dr. Melfi (Lorraine Bracco) essentially get whacked on last night's episode? In what came as a bit of a shock to viewers, a frustrated Tony (James Gandolfini) suddenly quit therapy — leaving the fate of Bracco's therapist up in the air. Is the actress — who recently replaced Kathleen Turner in The Graduate on Broadway — leaving the mob drama? "We don't discuss plot points," says an HBO rep. Well, we're going to go out on a limb and assume that Tony's days on the couch are far from over.
