Episode Plot

To be added


  • The three "ghosts" who appear to Oliver are a reference to Charles Dickens' A Christmas Carol. In following this, Shado is that of the past, with Slade representing Oliver's current self doubts, and Tommy finally offering redemption and a future for Oliver.
  • Slade in the present day has an eye patch and his hair appears to be greying, both elements which are usually present on Slade's character.
  • The scene at the end where Barry gets struck by lightning will later be used in the Pilot episode of the spinoff series The Flash.
  • Reporter "Linda Park" is a reference to the third Flash Wally West's wife, who would later appear in person on The Flash.
  • This is the only episode in the Arrowverse that include both Colin Donnell and Grant Gustin.
  • In one of the relatively few direct references to her Judaism, when Barry asks what Felicity will be doing for Christmas she replies, "Lighting my menorah."
  • This episode talks about the English nursery rhyme, "Solomon Grundy", stating that it's about the seven stages of life.
  • When Oliver hallucinates Slade and tries to fight him and cannot touch him, it strongly references the animated series the Teen Titans episode: "Haunted" in which Robin hallucinates Slade (which has been caused by a chemical reagent) and tries to fight him to which Slade is not there due to him died in the season 2 finale.
