Ah it will be bitter sweet for them to part.  But I think the prehistoric story ark has run it's course, unless you're planing another twist.

i like it, what i didn t get was why the person who goes after her cant come back with her... 

I came late to this story on the board but I love every chapter.  I don't know why somoene didn't try to put a stop to Willow before now.  She has really gone too far. I just know that Spike is doing all he can to not walk out of the house and hunt Willow down.  I do like the trick on Angel.  He just never learns.  He couldn't even watch Willow before stepping in it.  But I have a feeling that if they do 'find' Buffy she may not want to go back.  She and Groma and Kaia have creaed their own family.  I hate that she had to go through all of that but at least they are out of the caves and on their own.
