The Crone wants to see Wyatt's future and needs to distract the sisters to do so. She gets a Kazi Demon to get the Kazi King and after she uses an old totem to steal their senses, and use them for herself (she steals Piper's sight, Phoebe's hearing and Paige's voice), gets him to attack the sisters again, even though they had vanquished him, so that she has enough time to hold Wyatt to see his future.
