S9, E12: Weaver confronts a dilemma when an influential alderman, John Bright (Emmy Award winner Bruce Weitz - "Hill Street Blues"), seeking treatment after a fall, tests positive for syphilis--potentially damaging information that could become public. Meanwhile, Carter is impressed by an irascible, old doctor, McNulty (recurring guest star and Emmy Award winner Ed Asner - "Lou Grant," "The Mary Tyler Moore Show"), who oversees an inner-city medical clinic. A sympathetic Kovac defies conventional ethics when he tricks a seriously injured patient, Tom (James Colby), who refuses to leave his dying wife's side, into believing that she has already expired. Pratt unilaterally allows a drug-addled man to be with his terminal mother. Pratt also keeps a wary eye on his mentally challenged brother, Leon (recurring guest star Marcello Thedford), as he starts a new job. And Weaver and Kovac differ on what to do with a young boy whose medical history suggests repeated child abuse.
