You can just think of it as an alternate universe and not him regressing, since what happened to him and his og dad will not be erased..
If he did regress, the sword he's holding should've vanished and went to its original owner
I wonder if #12 and hunter Woo Hwijae had became a separate entity now that both future and past presence are in the same timeline.
future Hwijae's version of number 12 seems a little different from Number 3's version of number 12.
And the child writing the name Woo Hwijae on the sand looks like he's number 12, but isn't it Hunter Hong that gave him the name Woo Hwijae? How did number 12 know the name before meeting Hunter Hong?
Or is it because number 12 is an already clever existence that he led hunter Hong in to naming him Woo Hwijae? Cuz, it always made me curious why Hunter Hong didn't gave number 12 his surname even after official adopting him and giving him a name,
