A Frozen Spirit

Syaoran goes and trains with Kurogane. Fai and Mokona break into the castle to see Sakura. But when they get there, they see the feathers that she was given come back out of her body, black, not white feathers. Mokona tells her the feathers are fake and she tells Chaos that she thinks that he is cowardly for trying to control her with fake memories. Chaos sends a challenge to Syaoran. Sakura asks Mokona to tell Syaoran that he doesn't have to worry about her, so not to overexert himself. Syaoran goes to the castle to fight Chaos, but after Syaoran throws Chaos' lightning attack back at him, Chaos freezes Sakura's body and soul. Chaos then shows his true form which is that of a giant bird.
