  • Jay Garrick is revealed to be on Earth-Prime after the Crisis and is still married to Joan Williams.
    • However, in the Stargirl tv series, it is actually revealed that he hails from the reborn Earth-2 in the Post-Crisis Multiverse[1] and eventually moved to Earth-Prime.
    • After moving to Earth-Prime, like on the Pre-Crisis timeline, he lost his speed due to his old age but he had his powers restored by the Speed Force's rebirth.[2]
  • Barry mentioned having used the neural hypercollider to see the incoming Crisis in "A Flash of the Lightning" which, according to Jay, happened "last year". As the Crisis happened in 2019, this further suggests that the timeline of Earth-Prime somehow was shifted to one year later after some alterations to the Timestream.
  • It is also confirmed that Nora's future was affected by the Crisis changes:
    • Barry did not disappear in the Crisis of 2024 and lived an happy life with his Iris;
    • Nora was born in 2023 and never had his powers removed by her mother;
    • Barry and Iris have another speedster son, Bart, who also grew up to be superhero, being mentored by all of their speedster family;
    • Jay Garrick also exists in this future, where he never came back to Earth-2,[3] but died against Godspeed.


  • Many future counterparts are mentioned in this episode:
