Ordinary Witches

Still not completely sure that the Avatars mean well, Piper agrees to switch powers with Phoebe so that she too can see Phoebe's premonition of a utopian world.  During the spell, Zankou, the most powerful demon in the underworld, senses the girls' vulnerability and attacks them, accidentally transferring their powers to innocent bystanders, who run amok with their new abilities.   Meanwhile, Brody's desire to kill Leo and the Avatars prompts Paige to take Brody on a journey back to his childhood when his parents were killed so that he can learn the truth. Finally, the Elders learn Leo's true identity.
