True but I can't deny this just feels different. I have no doubt they'll establish which Earths these other shows come from making them all canon and part of the shared multiverse, hell, they some of them could even be some of the same Earth we saw on Jay Garrick's map meaning their universes already crossovered through mention and I'm pretty those shows will be affected in some way. Most other crossovers don't even go that far, it just happens and the next few episodes will be as if it never happened in the first place, I highly doubt that's the case with Crisis and everything we know so far
