This post has been edited for correction on the eyes!! >________< I guess, I'm still confused after all.
The eyes aren't that confusing to me as long as you remember which is from which.  I don't think I have to put down spoiler tags down anymore for this.  >_>
R!Syaoran gave his "left" eye to C!Syaoran.
C!Syaoran became blind in his "right" eye because his "right" eye is R!Syaoran's "left" eye.
Now, R!Syaoran has come back for his "left" eye.
C!Syaoran took Fai's "left" eye for his magic so it became his "left" eye.
Now, Fai is without a "left" eye.Â
There we go!  ^_^  The whole "eye" food pyramid sort-to-speak.
*gets out a tent and sits outside it waving little flags that say 'Hurry up Sei-chan', 'Wake up Subaru!' and 'KuroFai!!!'*
*gets out my tent and joins you guys on waiting*
*waves flag*Â Â Someone stop C!Syaoran from going crazy!!
