About the curse, this is what I've gathered. Tell me if I've got it wrong:
It appears that the "kill person with stronger magic than you" works only once correct?
FWR intended that this curse would be used to kill R!Syaoran, specifically in the world of the chess game (cant remember world name)
Sakura pays a price, stops it and gets stabbed herself. Hence the curse should be lifted as Fai did kill her (kinda, I assume it'll count as he hasn't tried to kill R!Syaoran)
HOWEVER! Ashura wanted the curse to be used to kill him. So he sealed Fai's magic hoping that when he finally went psycho and started killing people while Fai was off travelling Fai would be weaker than him still and have to kill him. That was poorly worded >.> Dot points!
-Fai is weaker than Ashura but left uncheked will be stronger
-Ashura slows Fai's magic growth with the tattoo. Tattoo also prevents him from killing those with stronger magic
-Ashura knew Fai's price would be the tattoo
-Block on his magic and the curse is lifted
-Ashura begins killing spree, Fai travels not getting any stronger as he's not using magic
-Ashura hopes when Fai returns to celes Fai will still be weaker & as the tattoo is gone will be forced to kill Ashura
-FWR hopes that R!Syaoran will become stronger than Fai before he has the chance to kill Ashura, hence negating the curse.
-Either way is possible depending on which worlds Mokona drops them in
But with Sakura's 'death' the curse is lifted and Fai has to kill Ashura the old fashioned way.
O.o have i got that right?
