Hi Mr. Gaiman! A question suddenly popped into my mind, and it's not making me sleep at all! In the Good Omens TV show, you added the final twist about the bodyswap. But is it really a bodyswap? How come when they shake hands to swap back, we see an external change? If the outward apparence is the one that changes, wouldn't that indicate that Aziraphale simply took Crowley's appearance, and Crowley took Aziraphale's? Because if Crowley and Aziraphale truly swapped bodies, the real change would be just internal and not visible to the eye, so swapping back wouldn't be truly visible. Does this make sense? Am I overthinking stuff? (I probably am)
It wasn't a body swap. It was an appearance swap.
I always thought it was more of a corporation swapping/mutual borrowing, like taking off a glove and giving it to the other to put on because they don't change their positions on the bench. Aziraphale as Crowley sits on the right and after the swap, he is still on the right (same with Crowley on the left obviously). If they had switched from one corporation to the other, he would have sat on the left, in Crowley's place, and moved to his body on the right (and the effect wouldn't have looked as cool on the screen). But if they are only changing their appearance, why do they need to hold hands at all?
Aziraphale literally said "swap back, then" so what did they swap?
Their appearances. (That's why I said above that it was an appearance swap.)
Why do they need to hold hands? Because it's more than an illusion, because it needed to fool angels and demons who aren't fooled easily. Big miracle energy. And anyway, they like holding hands.
