Their is something Kurogane says in the third book... 'you don't wheather she is awake or asleep at the oar.' It probably means she is clueless because of memory loss, and isn't sure about the world, because she always seems to be tired. Since she falls asleep. Everywhere.
Yesh, I agree, Fye seems to be a really good character ^^ I like it when hes talking to Mokona... they get along so well!! Also when in the country of fog... if you haven't seen don't read... in book 4. Oh yesh, this is the original script by CLAMP... translated. Goes to them!
Fye: The fog's gotten thicker, hmm?
Kurogane: Yeah. Pretty thick huh?
Fye: We've gone a pretty long way, and haven't met a soul. I don't think anyone lives here.
Kurogane: It's scary. Very scary.
Fye: Don't worry. I'm here to hold your hand.
Kurogane [Mokona Imitate]: OOH! That makes Kurogane soooo happy!! ^^
Kurogane: Who are you calling Kurogane?! You're Mokona! Speak for yourself!
Mokona: Kurognae's mad at me! ^^
Kurogane: Don't say disgusting things in my name!!!
Fye: But Mokona, you've gotten very good at imitating voices. It sounds exactly like Kuro-myu!
Mokona: It's one of Mokona's 108 secret techniques!
Fye: And the other 107?
Mokona: They're... a.... secret! ^^
Fye: Mokona! You're such a tease! I have to tickle you!
Kurogane: Have a nice life you two. (walks off)
Ha ha, that was really funny when you read it! It isn't if you don't see the pictures as much, but it's really funny! He he. One reason why I like Fye and Mokona.
