If the Flash is supposed to be some alternate dimension, it cheapens the crossover, as there's no stability--i.e. a chance for regular appearances from anyone in his world. ...and before someone says, "b--b-ut DC had dimension and world (ex. Earth II) visitis forever," I would say TV is not going to be so liberal with that option.
Early on, I predicted that would be a part of the series; its too strong a plot to avoid using--especially with what was established in this week's episode.
And they're introducingin the previous episode, so maybe they could also have something to do with it...Project Cadmus
