2038A

2038A is an alternate timeline where Shelby and Cyd time-traveled to the future and were inspired to form a Bionic Superhero Secret Service Division. It is the current timeline, since the current time-travels of the Bionic Superhero Secret Service Division have no effect on the world if they travel during their own lifetimes. This means that despite all the changes made in the first ten episodes of Season 4, the preservation effect continued to keep the memories and timeline intact, thus at the moment preventing new timelines from being formed. If they travel outside their lifetimes, however, it has an effect, but since the Waverider exists outside of time, it is hard to determine it's exact present.
