Trivia

  • The inmate rooms inside of Arkham Asylum contained nods to several Batman villains on each door except for one that references writer and former showrunner Marc Guggenheim.
    • Oswald Cobblepot, Pamela Isley, Basil Karlo and Edward Nigma are the real names of Penguin, Poison Ivy, Clayface and the Riddler respectively.
  • Some of the locations in Chicago that were filmed in this episode were the same locations used in The Dark Knight trilogy to replicate Gotham City.
  • Bruce Wayne, or Batman, is constantly referred to during the episode. He has been referenced by numerous people before, including Rip Hunter, Kara Danvers, Winn Schott etc.
  • The wifi password Kate gave to Oliver, Barry and Kara references Batman's butler Alfred Pennyworth.
  • Nora takes a freeze ray from glass case that's labelled Fries, V. This is a reference to her husband Victor Fries, or Mr. Freeze, one of Batman's greatest villains.
  • When Oliver (as the Flash) misaims a lighting bolt, the gas released falls out of a box labelled "Crane, J". This is a reference to Jonathan Crane, a.k.a. the Scarecrow, one of Batman's greatest villains.
  • Digger Harkness' boomerang, Bane's mask from The Dark Knight Rises, Hugo Strange's sunglasses, the Riddler's cane, the Penguin's umbrella, and other items can be seen inside of Deegan's lab.
  • Kara finds a William Shakespeare bust in a box which is a reference to the 1960's Batman TV series where it has a button to the entrance of the Batcave.
  • A Gotham police officer mentions Nolan and Burton streets. This may be an homage to Christopher Nolan and Tim Burton, two directors of Batman films.
  • The Earth-Ninety Barry mistakes John Diggle for John Stewart who in the comics is one of the characters who become Green Lantern.
  • Barry narrates the opening introduction (using the name Oliver Queen) due to the altered reality where he's Oliver Queen/Green Arrow.
  • Stephen Amell and Cassandra Jean Amell are husband and wife in real-life.
  • At the end of the episode, the Monitor reveals that he is preparing them for a "Crisis". This ties in with the red skies emerging in the first two parts of the crossover. Both are a reference to the Crisis story arc, which includes Crisis on Infinite Earths, Infinite Crises, and Final Crisis.
