Ah, fake feathers. That explains a lot. Chaos has his own feathers, which are much weaker than Sakura’s ones, but work in about the same way. When you combine a lot of these feathers, you do collect a considerable amount of power, and that was what Fei Wong is after. It also explains why this arc, even though not part of the manga, seriously disrupted the feather count, the reason Chaos went to travel to the Clow Country, as it never happened and why Chaos’ feathers coincidentally appeared to contain his memories. Still, it does not explain why he fell in love with Sakura. I think he fell in love with her because they’re both beings with a huge power.
Okay, only one episode’s left in this series, and the creators couldn’t have found a more fitting climax. Even though Chaos is proved not to posses the powers, equal to that of a god, he still has frozen both Sakura’s body and soul. I also loved Wei Fong’s role in this episode. It’s not yet clear what exactly he’s trying to do, but it’s great to see him get in action for once. The next episode should prove to be worthwhile. And after that, it’s waiting till April for the third season!
