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 feast depicted in the episode and named the "Feast of St. Elzéar," is based on the annual Feast of St. Gerard, organized every October around the church of St. Lucy's in the Seventh Avenue of Newark. This is a historical neighborhood of Italian-Americans, which used to be known as the First Ward. In addition to the street procession with the dollar-bill-covered statue of the saint, the feast features light shows, street decorations with colors of the Italian flag, food stands, and music. David Chase said that he wanted to create an episode about the feast ever since the first season.
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.
