  • The episode title is a play on the phrase "deus ex machina".
    • It is a reference to the end of the episode, in which Bishop drops from his Waverider while strapped to the toilet.
      • These events reveal what happens when the red button on the Waverider's toilet (previously discussed by the Legends in the season 4 episode "The Getaway") is pushed; it functions as a mode of evacuation from the ship, with the entire toilet dropping out through the floor, with the user intended to be strapped in via a seatbelt.
  • It's revealed that Bishop created the copies of historical figures such as J. Edgar Hoover and Thomas Edison by combining his clone tech with Gideon's computer tech, resulting in the creation of the robot clones.
  • After Assistant Ava and Bishop finish creating the J. Edgar Hoover robot, Assistant Ava says "It's alive!" This is a reference to Victor Frankenstein's creation of his monster in the Mary Shelley novel Frankenstein.
  • After Gideon locks Assistant Ava in the cargo compartment, Ava asks Gideon to open the door, to which Gideon responds "I'm sorry, Ava, I'm afraid I can't do that". This is a reference to the 1968 film 2001: A Space Odyssey, in which the character Dave Bowman is similarly locked out, asking the ship's AI Hal 9000 to unlock the pod bay doors, but she refuses in the exact same manner.


  • In the official press release for the episode, Adam Tsekhman's name was misspelt as "Adam Tsekham".
  • The magnetic, conductive material required to "fix" the time machine compass would be any ferromagnetic material, and would be known to Zari or Behrad. The parts collected in the base didn't appear to be any form of magnetic material, but bulbs or fuses of some kind.
