Trivia

 * According to Jody Mills, she first met Asa Fox when he came through Sioux Falls on a ghoul hunt during which time he identified himself as FBI Agent Fox Mulder. Fox Mulder was one of the protagonists of the show The X-Files where he and his partner Special Agent Dana Scully investigated aliens and other paranormal phenomenon.
 * Sam described Dean as someone who prefers anime porn or hentai. This was revealed in season 7 episode "Meet the New Boss".
 * Garth Fitzgerald IV is mentioned in this episode. Somehow, he became aware of Sam's possession by Lucifer and had passed on this information to other hunters.
 * This episode is the first time a full exorcism has been performed since Mother's Little Helper two and a half years earlier. While Sam exorcised Crowley in Hell's Angel, he didn't return to Hell but rather his usual vessel. It was also to rescue Crowley, not to defeat him.
