Charmed

Cheaper by the Coven (7x3)

Air date: Sep 26, 2004

When Paige and Phoebe summon Grams for Chris's wiccaning, Grams puts a spell on the children to try to end their sibling rivalry, but instead it reverts the sisters back to bickering teenagers. Meanwhile Phoebe, still acting like a teenager, attends an award ceremony with Les, and Leo consults a demonic seer to find out who is behind the attack on Wyatt.
