What happens next?

Drusilla and Spike have a slight disagreement

"For God's sake, Spike, Mummy understands you might be a bit peckish but Mummy still expects you to have some standards," said Drusilla. "I mean, a Slayer? Really?"

"What's a Slayer?" asked Buffy.

"Be quiet, Buffy," said Drusilla. "Mummy's talking."

"Who's Buffy? My name is Anne."

Drusilla sighed. "Just because you like to play dumb, Buffy, doesn't mean I do."

"But she's not playing, Dru," said Spike. "She really doesn't know who she is. It's almost like that time two Halloweens ago when she was under the spell of that costume the warlock had sold her."

"You mean that time you had a chance to kill her and you blew it because you waited too long to do so?" asked Drusilla.

"Well, if you must put it that way --"

"And now you're doing the same thing again?"

"Well, I am only human."

"No, you're not human," said Drusilla. "You're a vampire. And she's a Slayer. If we don't kill Slayers whenever we get the chance, then they kill us!"

"I still don't understand," said Buffy. "What's a Slayer?"

"You are," said Drusilla. "But you need not worry your pretty little head about that right now. Just look into Mummy's eyes, Buffy, and I promise --"

"I ain't doing anything with you, weird lady, unless you pay me," said Buffy. "And who's this Buffy you keep referring to? Like I told you before, my name is Anne."

At this point, Drusilla just shrugged and smiled. "All right," she said. "I guess we're just going to have to do this the hard way."
