Oh, yeah, Japan's immigration policies are ridiculously exclusive. It's virtually impossible to become a special permanent resident, let alone a citizen, if one is not ethnically Japanese--and additionally, Shaoran and Sakura would have real trouble since a husband is customarily head of household, but heads of household are not customarily foreigners (I think it's now legal for wives to be head of household, but if so it's a very recent development, and I think it's still illegal for foreigners).

But in one of the Clamp in Paris reports I saw that Ohkawa said the question of what Shaoran was doing in Hong Kong was going to be answered "very soon," which is why I'm bringing it up now.

This whole tube business, I can't even keep it straight anymore. It's hard to remember that these chapters are taking place in the past, too. So I guess the fact that it is/was/will be the clones in the tube is proof that they managed to change the future, at least a bit?
