What happens next?

Buffy and Willow go after Anya

"Look, Buffy," said Willow-in-Anya as the two of them walked down the hall toward the detention area. "There goes Anya. I mean, you. No, I mean --"

"I know what you mean, Willow," said Buffy-in-Willow, seeing the short blonde woman who was in the company of an older blonde. "Let's grab her."

"Right now?" asked Willow-in-Anya. "But she appears to be in the company of a teacher's aide."

"But if we don't grab her now, we'll lose her."

"But the teacher's aide --"

"Won't interfere," said Buffy-in-Willow. "I promise."

Then Buffy-in-Willow shouted,"Hey, Anya!"

The short blonde girl looked at the two of them with a startled expression on her face. Then, when she spied Buffy-in-Willow and Willow-in-Anya running toward her, she panicked and tried to run back into the ladies' room. Buffy-in-Willow and Willow-in-Anya caught up with her there and cornered her in a restroom stall.

"Okay, Anya," said Buffy-in-Willow. "Cough it up!"

"Cough what up?" said the woman with Buffy's old face. "Who's Anya? I don't know what you're talking about?"

"What do you mean, 'who's Anya?'" said Buffy-in-Willow. "You're Anya."

"No, I'm not," said the frightened woman. "My name is Mary Noxon. I'm a teacher's aide. I was just about to escort a detention student named Buffy Summers back from the ladies' room when suddenly she shoved something into my hand and then everything went black. I woke up in this body and then suddenly --"

Buffy-in-Willow did not bother to hear more. She was already checking the hall outside for signs of the older woman but of course by then, she was gone.
