If I became lost in the multiverse, exploring infinite parallel dimensions, my only criterion for settling down somewhere would be whether or not I could find you: and once I did, I'd stay there even if it was a world ruled by giant spider-priests, or one where killer robots won the Civil War, or even a world where sandwiches were never invented, because you'd make it the best of all possible worlds anyway, and plus we could get rich off inventing sandwiches.
