Yeah... You know, actually, I've been wondering all along if Yue would play a role in Tsubasa or not, and what exactly would his role be, since Yukito has already shown up and has not shown any signs of a split personality. I've been meaning to write an essay on this, but I actually think that Tsubasa throws an entirely new light on the Yue/Yukito question of to what extent they are the same person and to what extent they are different people. I've come to the conclusion that Yue and Yukito are exactly like the Tsubasa concept of different people with the same soul living on different worlds; Yue and Yukito share the same soul, but have entirely different memories.
And I'm interested to see if Eriol shows up as well. And Nakuru and Spinel... I know a lot of people hate Nakuru, but s/he's funny to me, except, of course, when s/he's trying to come between Yukito/Toya, one of my One True Pairings of All Time. But s/he never succeeds, so it's alright. And it's kind of funny to see Touya so upset. He's too serious so much of the time.
And we've gotten off track of Chapitre 100, haven't we? Anywho... I'm going to theorize that Eriol will be the Librarian or something in LeCourt, and they'll have to see him to get the book with Sakura's feather, just because I think that would be neat, and we have yet to have any crossover characters in this world.
