Boy, I don�t know where the Watcher�s council�s going to go. They�ll always be around and they�ll always be a part of Buffy�s life, but I think that as she grows up, she needs them less and less and as Giles separates from her as a father figure, he�ll need them less and less.
They will always be around and they will always have an influence, but I think that Buffy is becoming more and more of an independent agent. In the history of Slayers, she�s lived longer than any other Slayer so she doesn�t need these guys.
She�s completely in unexplored territory, and the longer she lives, the further she�ll go into unexplored territory. I don�t see the Council having a big influence over Buffy in the future, but they may come back.
