Willow and Tara have a quarrel, and Willow leaves Tara alone in a festival. Glory sucks Tara's mind, and Willow uses a powerful black magic trying to defeat Glory.

The climax of this episode is the conclusion, with Glory disclosing the identity of The Key. Willow realizes that she is not as powerful as she believes, and Spike gives good advices to Buffy. Glory asking if anybody has order an apocalypse is hilarious. My vote is eight.
