Change the DCEU with Flashpoint. It’s a win for fans and a way for WB to save face without having to reboot/scrap the DCEU.

For those who haven’t read Flashpoint just look it up.

The movie doesn’t have to be 100% based on the comics Flashpoint. This means that in the DCEU version, the Flash could come back after the events of Flashpoint and find that the Batman is no longer Bruce Wayne (Ben Affleck), but a younger guy (Jake Gyllenhaal) who happens to be mentored by Bruce Wayne!

This way they also conveniently solve the “Ben Affleck leaving the DCEU” problem!
