Re: xxxHolic 183 Discussion/184 Prediction Thread
Eh... I don't know. That theory is, by no means, impossible; anything is possible at this point.
...But I really don't think that it was meant in a totally literal sense (that Watanuki would need the actual items in the shop).
Speaking of wishes and compensation, if you think about it, most of the prices (that we were informed of) turned out to not be such huge deals. Instead of the physical item being the price, Yuuko's customers' prices were more of the journeys that they all had to go through to overcome not having whatever it is that they handed over. All in all: in the end, they wound up not needing whatever they "paid" with.
Of course, I can't say this for everything, especially since the stories aren't over yet; I was just generally speaking.
The shop, for Watanuki, has already helped him so far in that he now wants to exist. Prior to meeting Yuuko (again), he always felt that he wasn't supposed to be in that world, so his very existence was always on the line. After starting to work at the shop, he not only established new relationships that he otherwise would never have had the opportunity to, but he rekindled and strengthened some relationships as well. For example, the time that he unconsciously tried to erase himself by falling out of the window, he was taken care of at the shop, thanks to Himawari's price. Then, there was also Doumeki who gave his eye to be able to see whatever it may be that Watanuki was going through.
He also learned many valuable lessons through many of Yuuko's customers. With his relationships and his new feeling of actually having a place in the world, he now wants to exist. He would have probably already disappeared if it weren't for the shop, so, in many ways, the shop has already done its job.
I'm sure that the shop will continue to play a huge role, especially at the end when things tie together, but the shop is already helping him.
