Instead of the universe being one where the Nazi’s won, it’s a tiny tiny change — it’s a universe where all water is actually blue instead of clear (excepting seawater, which is green). Or a universe where people’s internal clocks are so slow to adjust that it takes immigrants years to sync up, condemning them to years of a nighttime existence. Each world could be a different episode.
I’m thinking they could be accessible via the alleys, since alleys are betwixt and between, themselves.
