Jonathan is the biological firstborn son of Superman/Clark Kent and Lois Lane and is half Kryptonian/human.
    • The fact Superman is taking Lois to Argo in order to safely carry the child (with kicking in the womb being mentioned a specific risk) is a callback to longstanding fan speculation over the logistics - and even impossibility - of superpowered Clark and human Lois having a child or simply a sexual relationship.

  • The crossover ends with the title of the next crossover, Crisis on Infinite Earths, which premiered in the Fall of 2019.

  • Barry and Oliver having a drink in the ending scene is a nod to the ending of "Invasion!".
  • When Barry asks Oliver to hug him, he rudely responds "no" as he made him hug him twice, referring to the episodes, "Legends of Yesterday" and "Invasion!".
  • In trying to track down the Cisco Ramon of the new reality, Barry tells Oliver that the last alternate version of Cisco he met wasn't very helpful, likely a reference to the version of Cisco that existed in the Flashpoint timeline, a business magnate with very little interest in metahumans and crime-fighting.

Goofs
