Who does the familiar voice belong to this time?

Anya

"Anya," said Buffy as she turned and saw a familiar-looking blonde-haired girl with an unique necklace. "What are you doing here?"

"Looking for Xander," said Anya. "What are you doing here, Buffy?"

"Er, I -- I -- I haven't seen Xander. And anyway, my name isn't Buffy. It's Anne."

"Seriously?" asked Anya.

"Yes, seriously," replied Buffy.

"Well, in that case, 'Anne', I hope you can give me some idea where I can find 'Buffy'. I really would like to speak to her as well."

"I'm sorry, Anya," said Buffy. "I don't think I know this 'Buffy' person you keep mentioning."

Anya smiled a secret smile. "You really don't know where 'Buffy' is, 'Anne'?"

"I really don't."

"You sure?"

"Hey, I wish I knew."

And then just like that, Anya heard some madwoman at the back of the club start screaming, "No! No! No! No! No! No! No! No!" until suddenly that same woman grabbed Anya from behind and started to hit her.

But by then, it was too late. Anya had already said the magic words: "Wish granted."

And while Amy Madison frantically tried to beat the tar out of poor Anya, Buffy woke up and remembered every thing she had done on stage. And then realized where she was right then.

At that point, instead of looking for her clothes, Buffy collapsed into a fetal position and started screaming her lungs out.
