OMG... I'm reading it now... and I found a subliminal message. Although the next image in the original context is actually painful... if you watch it with eyes of yaoi-ness, you'll find the answer:

It's officially cannon...
xd *faints*
NO! NONONONONO! Why should it end if they find his left eye!?!?! Now I don't want Fai to have his eye back! I want them to stay together forever!!! NO MOKONA! Don't be happy! I want vampire-ness and Kurogane-dependance and blood drinking and the stuff that comes with it!!!
Wow... Mokona does care for Fai... a lot. Mokona loves Fai!
heart So he has the other feather!? Wait a minute... How did Fuuma lay his hands on it? Wasn't it in the water reservoir along with the other feather?
Seems that Kurogane has his doubts about original Syaoran...
eek You were right, Sailor Yue, it's disappointing that Fai can return to normal...
