Buffy fanfic influenced by The World's End?

[dragonyphoenix]

This popped into my head this afternoon. Wasn't there a Buffy fanfic influenced by The World's End? I don't recall much but I think a character gong from pub to pub. I want to say Xander but I may be wrong. And perhaps Ethan turned up? I really don't recall it well but have a sudden urge to reread it.

Thanks!
