The one thing I don't like about the Earth-Prime characters is, if we believe the Earth-Prime characters are not their doppelgängers from the original multiverse, how would J'onn be able to give the Earth-Prime versions of characters memories from their Earth-1, -38, and -BL selves? In simpler terms, how is it that J'onn could give them memories that aren't their own?
