Actor Tony Sirico, who plays Paulie, cited the final scene as probably his character's favorite thing to do with his mother as a child, going on to explain that he really has no one else who loves him, which would explain Nucci's sudden change in mood and silence.
The flashback scene of Christopher telling Tony that Adriana had been working for the FBI was originally shot as part of the episode "Long Term Parking."
Paulie is not able to sleep and anxiously calls his doctor to learn the results of the prostate biopsy at 3 am. In the episode "From Where to Eternity," Christopher, awoken from a coma, gave Paulie a message from what he claimed to have been the afterlife he visited: "at three o'clock." Paulie disavowed the Church in that episode. This time, Paulie curses at the statue of Saint Elzéar, refuses to pay for its hat to be carried on it during the procession, and insults his adoptive mother mentioning sinful deeds until he has a disturbing vision of the Virgin Mary at the Bada Bing.
The movie Christopher is watching at the start of the episode is "Saw 2"(2005).
The episode uses a reference to Hurricane Katrina. Tony runs into Paulie in the bathroom and says "you're doing a heck of a job there, Brownie," a reference to a similar statement made by George W. Bush to then-Federal Emergency Management Agency director Michael Brown.
