bearmoon, just wait. you may be surprised.
as for the Clow staff in Yuuko's store room, Yuuko technicaly LIVES in the CCS world. she told watenuki in vol 2, before she sent the TRC gang on their way that there were versions of sakura and syaoran living in their wolrd, with different destinies. destinies that involve the creater of the orignal Clow staff. (i dont have the vol in frnt of me to get the exact reference she makes, but its in ch 1 of vol 2 of xxxHOLiC)
and kuma, that ruins it all for bearmoon, even the stuff not in the spoiler tags.. she's only upto date with the relases,. some people choose not to reed scanlations.
