Trivia[]
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, thus ending it on a cliffhanger.[1]
This is the last episode to feature Nick Zano (Nate Heywood) as a series regular, since he left the show before it was announced that it was cancelled. Zari Tomaz was written out of the series with him as both Nate and Zari decided to live in the Air Totem together and take their relationship to the next level.
When Sara and Ava arrive at the pocket dimensionmanor 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 in 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.
This is the first and only season finale to not feature Dominic Purcell (Mick Rory) in any capacity.
Goofs[]
In the official press release for the episode, Jes Macallan's last name was misspelled 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.
