This is it: with just one episode left in reserve (presumably for an epilogue), the big clash between Team Eriol and Team Sakura has finally come. After revealing himself, Eriol releases the true forms of Spinel and Ruby, and the trio really play up the Big Bad Villain act.
Eriol shrouds the entire city in darkness, which puts everyone to sleep except for Sakura and Syaoran (though even he’s woozy). If Sakura can’t lift the darkness spell by daybreak, everyone will remain asleep…forever.
The show makes a point to underline the stakes by showing almost every secondary character out cold, including Touya, who has no more magical power, after all. Sakura asks Eriol why he’s doing all this, but Eriol will only tell her if she breaks his spell.
Spinny and Ruby aren’t just arrogant, but also exceedingly powerful, and even when Yue arrives to shield Sakura, both he and Kero have a tough time keeping pace with Eriol’s guardians. The aerial battle between Yue and Ruby in particular is a beautiful action set piece.
Once it’s clear Sakura will have to stop playing defense and do something about the darkness spell, she takes out her cards, notes that eight Clow Cards remain to be converted, and then proceeds to convert six at once. Two “refuse” to change, however: Light and Dark.
Since those cards are most closely tied to her guardians, Kero and Yue tell Sakura to absorb the two of them into her staff. She does so, and her staff becomes longer and grander; Syaoran helps her hold it steady, and relies on his Clow Reed blood help convince the cards to change.
Once both Light and Dark are Sakura Cards, Sakura invokes Light, which proceeds to shatter the darkness and restore the regular sky. Everyone wakes up, safe and sound, and Eriol and his guardians stand down, his mission to help Sakura convert all of his cards now complete. Call it tough love on his part: in order for Sakura to summon the power, he had to create a crisis only she could fix.
When Kero and Yue go chasing after Eriol, Spinny and Ruby, Sakura prepares to follow, but Syaoran holds her up so he can tell her something he’s been wanting to tell her practically all season: he likes her. That’s right; the kid finally got the words out!
Alas, all he gets in response before the credits roll is Sakura’s shocked expression. But as she puts it in the preview for the finale, she once had no idea how she felt about Syaoran…but now she does know.
