It takes place around S4 or S5, but it's leveraged off of the episode 'The Wish.' Buffy saves a small demon from attackers, but is mortally wounded. In order to save her, the demon sends her to an alternative reality where she never came to Sunnydale, hence the Master was "successful" with his human blood draining machine. Unfortunately, this created a world with no more live humans; it's ruled by vampires (they drink from animals now). She's also been transformed into a vamp to blend in. But she's new with no papers and gets harrassed by the cops. She sees Spike and yells for him to help her. He does because he's curious and recognizes her scent, and brings her to his apartment and then an alien looking demon, who wears a bear-like disguise, to forge papers for her. Then they go to Giles, who was vamped by Willow, to help her get back to her reality. I believe they claim each other before she goes. When back, she tries to re-establish a relationship with Spike, but he's reluctant because her feelings are for the other Spike. Eventually, the two Spikes are merged (as well as Giles'), so all is good.
I could have sworn I read this here. And I know I found it before by simply searching under summary with The Wish, or Wishverse. I can't find it in any of the sites I favor, nor here through Find-A-Fic. Have I lost it or was the story taken down? Can anyone help me? |
