  • This episode serves as the series finale of DC's Legends of Tomorrow, as the show was canceled by The CW on April 29, 2022.[1]
  • When Sara and Ava arrive at the manor and none of the other Legends are there, Sara asks if the Legends agreed on Wednesday night instead of Sunday night to gather every week. This is a reference to Season 6's time slot, which was on a Sunday night.
  • Its worth nothing that Nate was the last Legend with unresolved business. Sara and Ava are expecting the birth of their daughter; Gwyn saved his love Allun; Gideon and Gary are a couple; Spooner and Astra are good friends; Zari 2.0 and Behrad have no lingering issues.
  • The Legends being "unavailable" after the Time Police arrest them in this episode is referenced on a whiteboard in A New World, Part Three.
  • It's not explained why the Time Police arrest the Legends; seeing as the team has been fixing the damages to the timeline for 6 years real time. Though it may be due to endangering a Fixed Point, which Sara did to draw Evil Gideon and the robot Legends; in order to steal their Waverider.


  • In the official press release for the episode, Jes Macallan's last name was misspelt as "Mccallan".
  • In the end credits, a credit for Superman's creators was shown, but there was nothing Superman related in the episode.
    • It is worth noting that Booster Gold is most commonly associated with Superman and the Legion of Superheroes due to him being based out of Metropolis and teaming up with Superman multiple times in the comics and using a Legion flight ring as part of his costume.
