At the end of last season, Barry once again gave in to temptation and returned to the night of his mother’s murder. It must be getting very crowded at that moment in time, with so many versions of Barry and Reverse Flash cluttering up the background. This trip, Barry saved his mother and caused a massive paradox, changing many events in his timeline (and presumably changing things for Arrow and the Legends of Tomorrow folks as well, since it’s a shared universe. Maybe this is how Supergirl gets integrated into the CW-verse?). In “Flashpoint,” a name full of meaning for a lot of DC Comics fans, we see the new world.
