Recently set photos from the upcoming flash movie shows what looks to be two different Barry Allen’s interacting with each other. While some people have thought that this might be reverse flash, I think mnm that it might be Barry from two different timelines. More specifically one is from the dceu and the other is from the new rebooted universe that is going to exist after the flash movie. Remember this movie is supposed to reset everything and possibly make the 1989 batman movie and a bunch of other stuff canon to the main universe. But this is going to make a lot of people mad so what i think is going to happen is instead of the universe being completely rebooted, its going to split into two, with one side continuing the main dceu and the other one containing the new movies. While they might not release any more movies that are canon to the old dceu, this will be a better way than just erasing it entirely. It would also allow the fans to chose what they want to be canon as some movies would fit into either universe. Remember one of the Barry’s from the set photos has longer hair and the other has shorter hair, he is going to have longer hair at the beginning of the movie and shorter hair at the end of the movie.
