Trivia

  • In Southern California, this episode along with The 100 episode "Die All, Die Merrily" were both postponed to May 6th due to coverage of the Giants/Dodgers game.
  • The flashbacks in this episode takes place between "Schism" and "Legacy".
  • This is the first episode of Arrow to not feature a main (human or otherwise) villain, nor does it involve other villains (although Adrian Chase appears at the end interacting with Oliver's son, William). Instead, Team Arrow faces the Arrowcave, which acts metaphorically as a "villain"; an EMP set off by Chase disabled the base where Oliver and Felicity are trapped, so Diggle and the rest of the team must rescue them before the air in the Arrowcave runs out.
  • Curtis refers to his T-Spheres as Kodo and Podo, naming them after "Dar's thieving ferrets on The Beastmaster". He also mentions former Arrow recurring actor Marc Singer, who portrayed Dar in the film.
  • Curtis refers to an "Earth-shattering kaboom", quoting the catchphrase of Looney Tunes character Marvin the Martian.
  • Curtis says that it will take "10 seasons of The Bachelor" for the hydrochloric acid to melt through the titanium hinges of the elevator.
  • When Curtis' T-Sphere opens for Felicity to reveal a needle, she quips that it looks like the "Death Star interrogation droid" from Star Wars: Episode IV – A New Hope.
