The current volume of Justice Society of America has, in a lot of ways, been built around continuity, most notably through a series of major retcons to the DC Universe that were introduced in Flashpoint Beyond, and then implemented in Stargirl: The Lost Children, which revealed that Doctor Manhattan had removed a number of people from the DC Universe timeline, and now they have been returned to history, but obviously the rest of the DC Universe has to get used to them now existing.
