Guest starring[]




  • The time displaced clothes Barry wore resembles the Star Trek uniform.
  • This episode resolves something from Season 1. The renewal of permits to allow S.T.A.R. Labs to stay open, which is now a decade past due.
  • Lady Chronos is somewhat an incompetent thief, similar to Star-Lord in the first Guardians of the Galaxy film; sure, she gets the prize she's after, but it sets off a chain of events that endangered her life and others around her.
  • Carla Tannhauser finally meets Khione; instead of accepting her in place of her daughters Frost and Caitlin, she instead becomes a role model and mentor. The fact she was unwilling to see Khione as family shows Carla is in her own depression.
  • Both flashbacks of Ramsey Rosso and Mitch Romero is foreshadowing both of their appearances in the next episode.


  • This episode took place on April 5, 2023, which is the same day this episode aired. However, a previous episode "The Good, the Bad, and the Lucky" took place on Jenna West's birthday, which was on May 22, 2023.
    • It is impossible for this episode to take place before that episode chronologically, since Barry mentions Mark having left Central City in this episode, but he worked with Khione to test her abilities in "The Good, the Bad, and the Lucky."
  • Even if it was 100 years later, the Flash Museum should still have had a recent inspection. Regardless if it's a monument to a hero, there are still things in the former S.T.A.R. labs that need to be checked on. Then again, Lady Chronos stated that the 2023 date was the last inspection "before becoming a museum." Theoretically, the museum just kept the old certificate as part of the display.
  • Back in Season 3, H.R. Wells attempted to open a S.T.A.R. Labs Museum, one which people did end up attending. Considering the particle accelerator explosion had occurred, one would assume S.T.A.R. Labs would need to undergo various safety checks/tests in order for the public to attend it. But apparently, the Museum could open without inspection.
    • That part was never mentioned in that episode since it wasn't a vital plot, So its likely they happened off scene and were never mentioned .
