"I'm saying that there is a man who killed Darhk in cold blood. And that same man stood on top of a car and gave the city its hope back. What you're feeling isn't darkness, it's a schism. You're at war with two sides of yourself."

Sneak peeks



  • This is the lowest-rated episode of Arrow, with a rating of 5.5.
  • Sara Lance later learns of the episode's events during "Legendary" and the madness Damien Darhk slipped into once he lost his wife. She taunted him with this in "Compromised", leaving Darhk to try and change his future by time-traveling with Eobard Thawne.
  • This episode is the very last time that Oliver and Team Arrow are in the original present day, before the aberration of the Flashpoint timeline and the events of "Vigilante".
  • The title of this episode comes from the conversation Oliver had with Felicity where she points out the two different sides of himself from when he murdered Darhk and helped restore the Star City citizens' hope.
  • This is the last episode to credit John Barrowman as a series regular, as he is downgraded to special guest star in season 5.
  • This is the last episode to credit Echo Kellum as a guest star, as he is upgraded to series regular in season 5.
  • In a flashback, Amanda Waller orders the Khushu Idol to be taken to The Slab. In the comics, The Slab is a maximum security super-villain prison based in Antarctica.
  • When Felicity is looking at the map of released missiles, Star City is located where real-world Chicago would be.
  • Oliver kills Darhk by stabbing him with an arrow, the same way Darhk killed Laurel in "Eleven-Fifty-Nine".


  • During the final showdown between Green Arrow and Darhk, a cameraman can be seen close to the camera filming towards the viewers' point of view.
  • Felicity says that the closest ICBM was headed to Star City from Warren Air Force Base in Colorado. If she is referring to Francis E. Warren Air Force Base, it is located in Cheyenne, Wyoming and not Colorado.
  • While Oliver is giving his speech on top of the taxi, one can see a Canadian flag flying from the facade of a building. This is a giveaway to the show being filmed in Vancouver, British Columbia.
