The title character is not the primary Blacklist character. In this case, Reddington (James Spader) mentioned the Coroner (James Hong) and confirmed he was a Blacklister before they learned about Dr. Shaw (Linda Emond). The titular Dr. Shaw was an identity created by the Coroner.
This episode was directed by Andrew McCarthy, who starred with James Spader in the John Hughes film Pretty in Pink (1986) as well as Less Than Zero (1987).
