I won't repeat myself, as no one seems to listen to me.
About this chapter specifically, I want to know how Kohane is going to influence the end of xxxHolic. The way Yuuko is talking, she is just as vital as other characters we have met, to Watanuki.

Many people have influenced Watanuki, and he has influenced them back. I'm thinking this is going to be very important in the conclusion. (Syaoran too!) If only I could figure out how...
