What happens next?

A solution?

"So do you have a solution for our little problem?" asked Joyce.

"We sure do," said Willow.

Tara reached into her purse and took out a small metal talisman.

"What is it?" asked Joyce-in-Faith.

"It's a Draconian Katra," said Tara. "It's very rare and it seems almost impossible to make from scratch unless you have the right spell and the right ingredients. And both can be hard to find."

"How does it work?"asked Joyce-in-Faith.

"It's simple, really," said Tara. "First you put it in the other person's hand like this, then you squeez -- No, wait, Joyce. Not ye --"

And just that, there was a flash of lightning, a sound of thunder, and then Joyce was looking at Faith's body through Tara's eyes and Tara was looking at her own body through Faith's.
