The Weight of the World

Glory is feeling guilty and confused and she feels also that the bond between Ben and her is fading. Meanwhile, Buffy is catatonic and Willow goes into her mind, finding that Buffy feels guilty for Dawn. Spike recalls that Ben and Glory are two entirely separate entities sharing one body and tells the Scooby gang. Glory is waiting for the exact moment to activate the key with Dawn's blood, turning down the barrier of dimensions and mixing the different realities into each other. But Ben wants to survive struggling with her. Giles reads an ancient document that Spike and Xander got from Doc and finds that Dawn must be killed to save the world.

In this weird episode, the duel between Glory and Ben is great, with intense use of special effects. However, the trip of Willow in Buffy's mind is repetitive, boring, silly and pointless. The conclusion of Giles means that the Knights of Byzantium were correct. My vote is six.
