Ok, here's my theory (I've posted it elsewhere, but not here). Buffy coming back from the dead has set up interference in the slayer line. Like two waves that have the same characteristics but are out of phase with each other, when they collide, interference occurs and both the waves are weakened. The question is, what is the power that Buffy's power is interfering with? The big eyeball thingy said the powers surrounding the slayer were unstable...Could the power interfering with Buffy be Dawn? As the key, she was very powerful. Could it be Willow? Anya at one point called her the most powerful Witch in the Western Hemisphere. This could be hyperbole, but maybe not. Heck, maybe the ripples caused by the presence of Faith are just hitting shore as it were. I don't know, I'm just putting my two cents worth in. In any case, I'll be watching to find out just what the heck is going on!
