Featured Supernatural Beings



  • This is the final season premiere of the series.
  • The Winchesters face off against Constance Welch, Mary Worthington and John Wayne Gacy who they previously fought in Pilot, Bloody Mary and Lebanon.
  • The episode title could be a reference to the 1985 American science fiction film Back to the Future[2]. It could also be a reference to the fact that all the souls that Sam and Dean Winchester sent to Hell from the past seasons are now back to the present, which is the "future" for the souls.
  • Sam says "We got work to do." in this episode. This is the fourth time that this was said by one of the Winchesters on the series with Pilot, All Hell Breaks Loose - Part 2, and Fan Fiction being the first three.
    • When the Winchesters close the Impala trunk, the scene briefly flashes to when they did the same thing in the Pilot.
  • The demon that took over Jack Kline's body is Belphegor. According to real life demonology, Belphegor is a demon and one of the seven Princes of Hell who helps people make discoveries. He seduces people by suggesting to them ingenious inventions that will make them rich.[3]
  • Belphegor reveals there were about 2 to 3 billion yet-to-be-demonized souls in Hell.
  • Its revealed that every door in Hell was thrown open by God, including the door to Lucifer's Cage. Dean expresses worry that Michael may have escaped, though the last Belphegor knew, Michael was still just sitting in the Cage.
  • The song opening the episode is Bob Seger's "The Famous Final Scene." It previously appeared in Season 9's Road Trip as the opening song.
  • For the first time, the Winchesters add jackets labeled FBI to their disguise instead of wearing suits.
  • Castiel uses a shotgun for the first time since Two Minutes to Midnight. Like that time, he saves Sam's life with it.
  • Belphegor suggests that the Winchesters and Castiel are responsible for the "hellmouth" situation. In Buffy the Vampire Slayer, hellmouth is place in which dimensional barriers are particularly weak, allowing to relatively easily move between dimensions in such places. Thus, a hellmouth is practically a gateway between different dimensions. Specifically, the town Buffy lives in, Sunnydale, is built just a top a rather dangerous hellmouth, connecting earth with an awful hellish dimension, thus Buffy must prevent from being opened. A second hellmouth is revealed to exist in Cleveland, Ohio in the Buffy series finale.
    • In The Gatekeeper Trilogy of the Buffy the Vampire Slayer novel series, Belphegor is one of the Big Bads.
  • Despite his vessel having no eyes, Belphegor's interactions with the world around him suggest that the demon can see just fine without them. This is contrary to the Waitress demon in Lazarus Rising who was blinded when her vessel's eyes were burned out by Castiel. However, in her case, the demon was possessing the vessel at the time it suffered the injury rather than taking over the body afterwards.
  • While Castiel heals Sam in the episode, he also fixes his shirt that was damaged due to the shot. This is the first time such effect appears.
