To clarify the choice you make would be just for one episode. Just like in the wish, were we got 1 episode showing us what it would have been like , then everything went back to normal. So it doesn't have to be something you wish had actually happened, just something that you would like to see for just one ep, but then it would be like it never happened.

Oh, and with the Dark Willow option I know it seems obvious (that she'd just end the world) but don't forget it was taking the magic from Giles that made her want to end the world, so if he had never shown up she would have done something else.

wow great pick props

It's funny that the Buffy-vamp one is winning because that's the only one I wouldn't be that interested in seeing. We've already seen what if characters we like were vampires in 'the wish' and we've seen what Buffy is like as a vampire in s1 'nightmares' so the others are more interesting to me.

I'd love to see any of the others especially what if Buffy had stayed in the fake world in 'normal again' because I think that one has the most interesting questions to be answered:
Could she stay in the fake world forever or would the demons poison eventually wear off/kill her?
Would she have been released from the institution and gone on to live the happy demon free life she can never have as a slayer with marriage a normal job and kids?
Would she have been happier there without the responsability of being a slayer or would she feel like something was missing?
would her friends have survived in sunnydale without her to rescue them from the demon she set on them?
There's lots more too. I'd love to have an episode cover those questions

Then we would be without Dawn for a whole episode! (Yippee!)

well not for the same reason as cinders lol, but it would have been really interesting to have seen that.

Oh, look at all the fanfiction plot bunnies.

I love all of the What-if's!

This might sound mean, but I kind of wish that Dawn had jumped. She was just never that great of a character for me.
