Speaking of souls, how long does it take before the soul leaves the body and you're truly dead. I think that Buffy was able to be revived 'cause her soul was still there minutes after her "death."
OK, so Buffy's essence never died and if we go with the theory mentioned, her prophetic powers where never past on.
Well, it was never mentioned about Kendra having any prophetic dreams. The reason's she new to go to Sunnydale were because of her Watcher, not because she was drawn there by her dreams.
meaning they where never past onto Faith. The dream at the end of Graduation was never specified who's dream it really was.
When Faith was dreaming in This Year's Girl, they could be classified as nightmares not prophetic dreams. If you remember the dream about them making the bed and it being linked in with the episode Restless you could argue that Buffy was sharing her dreams with Faith.
So, if we go with this, then Buffy never past on the essence trigger. So, to call the next full slayer, with physical and mental powers, Buffy's essence in Faith's body would have to be killed.
