Complete story — includes the ending
The Watcher's Council withholds information about Glory from Buffy and make her go through a series of tests. Glory and the Knights of Byzantium target Buffy, and she realizes it's because she has power over them. She confronts Quentin Travers and the Council members he brought with him, and makes it clear they work for her, not the other way around. Buffy orders Quentin to give her the scoop on Glory, and learns she is not a demon - she's a god.
