I've read up to 230, too. And I really don't see how Watanuki could've ended up as FWR, unless there was something over in xxxHolic (which I haven't read in months and months, because it sucked) that really cinched the deal. Frankly, I can't possibly imagine that CLAMP would do that. I know that they're terrible writers, and I know that they love to give their characters tragic endings, BUT. There's a difference between "tragic" and "pointless," and if Watanuki grew up to become FWR, that would be the ultimate pointless ending for this series. It would completely undermine all of the themes that CLAMP established (and then proceeded to bludgeon readers over the head with OVER AND OVER AND OVER AGAIN) in both Tsubasa and xxxHolic - about the power of love and friendship to overcome all obstacles (even incest), about the nobility of sacrifice, about learning to let go when it's time to let go, about learning to appreciate the love that others are willing to give to you.

Besides, CLAMP has already gone to such lengths to drag the Tsubasa characters through the mud and then magically save them all through a series of increasingly ludicrous deus ex machinas, that I really can't buy, at the point, the idea of anything less than a (poorly conceived and atrociously executed) happy ending for all non-villainous parties involved, including Watanuki.

Also, why would Watanuki become the guy who tries to kill Sakura in the first timeline? Why would he try to kill his own mother? Then he would cease to exist!
