I really am starting to suspect, personally, that FWR is Clow and Yuuko's son. It makes so much sense, at least to me.

I also like your point about the relevance of interrupting the final battle--if the clones become people who are completely unrelated, it's way more appropriate to have in an epilogue or other sort of atogaki. Particularly since Ohkawa is totally leading us on when Yuuko says that what happens when the reincarnated clones meet the originals will be up to them to decide.

I also agree that the thought of CCS!Shaoran and Sakura having to suffer so much pain is just too sad. ;_; Sad I tell you.
