User blog comment:GlaceonGamer5x/Could Barry be a founder of the Justice Society of America?/@comment-24830227-20160525050019

Well... they cant use the League for sure. That's all but confirmed by the mega blockbuster coming out next year. But GJ has deep ties to the Justice Society, so I'm not surprised that they did it. I honestly thought they would call Legends that in the first place. In terms of the Barry thing, that would seem to be correct. However, given the fact that Grant was too busy to shoot a single episode of Legends this season, and it seems it wouldn't make sense to have him be part of the Justice Society if he could never appear on screen with them. Maybe the Justice Society is from our core heroes' (Barry, Oliver) future and they found it as more experienced heroes. The best thing I could think of is maybe our mega cross-over tells the story of the Justice Society and that's how we implement the major show protagonists into the story.
