Wow, the story is really long. Maybe I'll have to make a break again soon.
So Giles and the girls know what happen now. They want to follow? I'll bet they don't expect to need other clothes to fit in ;-)
I wonder what claim it was that the rider placed on Buffy and if another claim could break that... but the claim the rider meant is more of the magic kind.
Useful information indeed :) Now off to find out more.
