Honestly, with all of this debate about whether Blue Beetle and/or TLK take place in which timeline, for a while my point of view has been that, if they take place in the same universe (because I believe Blue Beetle takes place in it's own universe which would merge with the main DCEU into the DCU even if it is not 100% official) it would be the DCEU, either if they happen before or after The Flash. I mean, if James Gunn by any reason says that they are set post-Flashpoint I would obviously listen to him, but that is probably not going to happen along with any possible answer to this debate since a new franchise is beginning and it won't matter to them anymore. A part of why I think of this being the truth is because the fate of DCEU's Earth-1 hasn't been confirmed to this day, so I think that Barry just created a branch timeline which merged with another universe simply because that is how time travel worked in that universe, Earth-1 would continue to exist and The Lost Kingdom would continue to happen in here if after The Flash (and possibly Blue Beetle too, but because of declarations by Gunn and the director it seems to take place in it's own universe. That doesn't change that, in either case it takes place before or after, I would watch Aquaman and the Lost Kingdom before The Flash in a viewing order. Thoughts?
