• This episode was intended to be the pilot episode for a Supernatural series spinoff. As of this writing, the show has not been picked up
• The five monster families that run Chicago are werewolves, shapeshifters, djinn, ghouls, and sirens (which are not mentioned in this episode)
• Several cast members from this episode have appeared previously in Supernatural: Melissa Rogers, the actress who plays Violet, played Lila Taylor (Kronos' girlfriend) in Time After Time (season 7); Gardiner Miller, who plays a bodyguard, also played the deadly sin Wrath in The Magnificent Seven (season 3); and Michael Rogers, who played Irv, was the deadly sin Gluttony in The Magnificent Seven

• Dean introduces himself and Sam as "Agents Bonham and Peart, FBI," referencing drummers John Bonham (Led Zeppelin) and Neil Peart (Rush), who are two of the best rock drummers of the 20th century.
• Julian says he wants to eat Taylor Swift's heart. Taylor Swift is an American pop singer
• Dean says, "What is this, The Godfather with fangs?" ?This references the 1972 movie based on Mario Puzo's novel The Godfather, which chronicles the trials and tribulations of the Corleone family as they battle the other New York City Mafia families for control of the crime empire.
• Dean says, "From what you told us, uh, this thing sounds new... or Freddy Krueger," referencing the famous dream killer played by Robert Englund in the Nightmare on Elm Street movie series since 1984, known for the clawed glove that he wears.
• Dean calls David "Romeo", referring to Romeo Montague from William Shakespeare's 1597 tragedy Romeo and Juliet. In commentary about the Shakespeare play, Romeo and Juliet are often referred to as "star-crossed lovers", meaning destiny will never allow them to be together, so they are destined for tragedy. In many ways, David and Violet are star-crossed lovers, because their families will likely never allow them to be together, just like Romeo Montague's family and Juliet Capulet's family from the Shakespeare play
• David says, "Sounds good, Buffy" to Dean. This refer to the 1992 movie and subsequent TV series Buffy the Vampire Slayer, which features the adventures of a teenage girl, Buffy Summers, the "Chosen One," who is gifted with special abilities that allow her to fight vampires, demons, and other monsters
• Sal calls one of the werewolves "Old Yeller" referring to the 1957 drama about a dog
• Ennis calls David a "transformer" referring to the fictional characters from The Transformers comic books (1984 - present) and sci-fi/action film franchise (2004 - present). Transformers are robots from outer space that can turn into cars, trucks, or flying machines to obscure their true identities in our world.

• "Somehow" - by Caught a Ghost (plays during Ennis and Tamara's date)
• "Little Black Submarines" - by The Black Keys (plays when Ennis returns home and searches through his father's things)
