This episode reveals a sexual affair between characters played by Edie Falco and Paul Schulze. In their previous show together, The Sopranos, their characters had a long non-sexual relationship that was fraught with sexual tension, her being a married woman and him being a priest. The episode that delved deepest into their relationship was "College", directed by Allen Coulter, who also directs this episode.
Peter Facinelli plays Dr. Fitch Cooper. He also played a doctor (Carlisle Cullen) in Twilight (2008).
