- It is possible this episode is a tribute to the movie One Flew over the Cuckcoo Nest.
- The insane asylum was also used in the filming of Freddy vs. Jason (2003).
- The set used for the hospital scene in 1969 is the same set used in Supernatural season 1 episode 'Asylum' and season 2 episode 'In My Time of Dying'.
- Emily, the alias Nora uses in the asylum, is a subtle reference to The Exorcism of Emily Rose.
- The exorcism that Constantine uses is the same as the TV show, Supernatural, which also airs on the CW.
- This is one of the only episodes of DC's Legends of Tomorrow to not feature any time travel through the use of the Waverider.
- The tarot card Constanine shows Sara Lance in the asylum back in 1969 is a shoutout to her transition from The Canary to The White Canary.
- It's revealed by Kuasa that Zambesi Village was destroyed in 1992 after Amaya was murdered by a warlord. When she tells Amaya about her future, she returns from time traveling.
