What happens next?

Anya thinks ahead

Meanwhile, Anya-in-Buffy was sitting in the classroom where all the students in detention were gathered and planning her next step.

Sooner or later, they'll come after me, she thought. And if they don't come after me here, they'll be waiting outside for me when school is over. Well, right now there is nothing I can do to prevent that but there is no law that says I have to make it easy for them. First thing I gotta do is retrieve the Draconian Katra from my belly. I can't very well cut myself open and waiting for it to pass the normal way would take too long. But if I were to induce a finger down my throat and **** myself to throw up ... Yeah, that would work. But I can't do that here; it would look too suspicious. However...

Anya-in-Buffy raised her hand. "Ms. Espension, may I please be excused? I need to go to the ladies' room."

"No, you may not," said Ms. Espension.

Well, there goes that plan, Anya-in-Buffy thought.

"However, if you really need to go," Ms. Espension said, "Ms. Noxon here will be happy to accompany you."

Anya-in-Buffy smiled.
