Willow Rosenberg slowly walked down the street nothing here looked familiar... the only thing she knew as she walked past the tattoo shops, the shops filled with latex and leather fetish wear, and other assorted shops... she was certainly not in Sunnydale anymore... at least not her Sunnydale.
She had not crossed out the possibility that she had crossed into an alternate universe version of her hometown.
The Witch had not been too far off while she is not in Sunnydale. Bimburg did exist beyond time and universal constraints. Which is why all over the city random women from all manner of universes have found themselves in random locations around the metropolis. All under the watchful eyes and planning of the mysterious mayor.
