Some of this is based on what I have read from rumour sites on the Internet, although they probably aren't much more reliable than what I'm making up right here. And I want to make it totally clear that this is all completely made up. This isn't authorised information in the slightest. Not that you really thought it would be, I'm sure.
And now, the Season 6 episode guide, prepared by Owen which is completely and utterly inaccurate, on account of me just having made it up right now. I haven't assigned names to the episodes, unless I think up a really good name.
Episode 1 (Part 1 of 2):
Buffy is still dead as a result of her confrontation with Glory in 'The Gift', and her friends are still trying to get over it. Knowing that evil still resides in Sunnydale, the Buffybot of the latter half of Season 5 has been revived and is being used to fight evil. Without anybody's knowledge, Dawn begins a spell like that she performed on Joyce in Season 5's 'Forever' intended to bring Buffy back.
Episode 2 (Part 2 of 2):
Dawn's spell works but when Buffy reappears at the Bronze, her friends assume she is a vampire and they call out the Buffybot to fight her off. Fortunately, after Buffy destroys the Buffybot to defend herself, Giles is able to tell that she is the genuine article.
Episode 3:
Buffy begins to readjust to being alive, but finds that she much preferred being dead. She prepares to kill herself again, but her friends find her just in time and persuade her how much she is needed.
Episode 4 - The Return:
Giles is recalled to the Watchers' Council in England to be debriefed about all the encounters he and Buffy have dealt with since he was fired in Season 3. He decides while in England that he will not be returning to America. Willow, isolated from last week's events, begins to feel bitter about not being included so often in the group's activities.
Episode 5 - Dangerous Game:
Willow experiments with her magic, and worries Tara by delving deep into the dark arts. Willow is not pleased by Tara's meddling, and uses a forgetfulness spell on her, so she forgets the whole thing.
Episode 6:
A musical episode. The whole episode is conducted in song, for some incredibly contrived reason. Everyone also reveals their innermost feelings and thoughts during singing. In song, Willow reveals that she cast the forgetfulness spell on Tara, who breaks up with her as a result. Meanwhile, Xander and Anya prepare for their marriage, and Buffy and Spike find out exactly what they do feel for one another.
Episode 7 - The Rift:
Willow is overcome with sadness that she and Tara are no longer an item, but instead of feeling guilty on account of it being her fault, she turns her anger outward, directing unpleasant spells in Tara's direction. When Buffy tries to convince Willow that her actions are unacceptable, Willow launches a full scale magical attack on Buffy. Buffy barely escapes with her life, and Willow flees from the scene.
Episode 8 - Love and Marriage:
Xander and Anya's wedding is overshadowed by the grim news Buffy brings of last week's events, and Anya throws a tantrum because no one is paying as much attention as she thinks they should to the marriage because of Willow. Spike comforts Buffy and it genuinely seems that the two are getting closer. Elsewhere, Willow is approached by a demon who wishes to recruit her as a servant to fight the forces of good, and, upset at recent events, Willow accepts.
Episode 9:
Xander and Anya leave on their honeymoon, leaving Buffy, Dawn and Spike the only members of the Scooby gang remaining in Sunnydale. They spend time at Buffy's house, the evening eventually culminating in Buffy and Spike kissing. Willow watches through the window.
Episode 10:
Willow goes to Angel in LA to inform him of Buffy and Spike's liaison, hinting that Spike has Buffy under some form of mental control. Angel, overcome with rage, comes to Sunnydale to finally put pay to Spike. A huge fight between them ensues, which ends in Angel staking Spike before Buffy's eyes. Buffy tells Angel in no uncertain terms to get out of her life, and will not listen to his explanations.
Episode 11:
Willow, gloating at the chaos she has caused, begins her next move against Buffy. Now she has caused the death of Buffy's current lover and estranged her from her former one, she seeks to kill Dawn as well. Fortunately, Buffy manages to fight Willow off, and calls Giles in England for help. Giles promises to return immediately.
And there, with that tantalising glimpse into events to come, I shall leave you. I'll put up the second half of the episode guide as soon as I've made it up, I mean, found out all the details.
