Cheaper By The Coven

Against Piper's wishes, Paige and Phoebe summon Grams for Chris' wiccaning. To put an end to the brother's sibling rivalry, Grams puts a spell on them, but in the process turns the sisters back to bickering teenagers. Meanwhile, Leo consults a demonic seer (guest-star Charisma Carpenter) to find out who attacked Wyatt and learns that he has a connection to Wyatt's attacker, and Phoebe attends an award ceremony with Les (guest-star Nick Lachey), only to end up acting like a love-struck teenager.
