  • This episode follows the pattern of the penultimate episode of a season being named after a Bruce Springsteen song, in this case after the 1973 song "Lost in the Flood".
  • Damien Darhk refers to the world going "Dr. Strangelove", referencing the 1964 film which ends with the world entering a nuclear apocalypse.
  • Felicity states to Curtis and Noah that the world will have a "sequel to WarGames" if they don't hack Rubicon and stop Genesis. This is a reference to 1983 film WarGames, where a young hacker, David Lightman, tries to stop supercomputer WOPR from launching nuclear missiles.
    • Curtis also mentions its 2008 sequel, WarGames: The Dead Code, which was released on DVD and, in contrast to original, panned by critics.
  • When Oliver and John enter Tevat Noah, John compares it to Mount Weather, a governmental facility which was built by FEMA during the Cold War.
  • During the hacking battle over Rubicon, Cooper Seldon taunts Felicity that they are going to "once more unto the breach." This is from Star Trek VI: The Undiscovered Country, which Curtis recognizes.
  • Curtis mentions that after doing some research, he figured out that despite all the crime that has plagued Star City, they live in the second most dangerous place in America. This is a very subtle Batman reference, as it's often joked in both DC shows and comics that The Dark Knight's home, Gotham City, has the highest crime rate in America.
