This part we had sort of already seen in the promo. But still ..YEAAH!
ry4christ: “I hope they explain the AU coexisting with the present reality with the “You can’t change the past” genie rule/law of magic. #continuity”
Is that a rule though? When was that established on the show? Two realities should be able to exist concurrently and if, with Genie magic, you can not change the past of this reality, that does perhaps not prevent a Genie from creating a nother reality..
