I hope it's all wrong. Surely the whole point of crisis and the merging of earths was to focus everything on one earth, but they allowed the multiverse again. Why? It's not as if their big plan of earth-prime characters coexisting has paid off. Kara gets sucked into the phantom zone and nobody thinks to at least give Clark or Barry a call? Barry is struggling with a lightning force and doesn't consider what Jefferson could bring to the table?
It's a royal mess. Stargirl is good. I don't want them to ruin that by suddenly throwing her in with Barry Allen and Sara Lance.
If there's a Jay Garrick on Earth-2, then great, but please for the love of god don't make him the same one that Barry will interact with.
