Cheaper by the Coven

After calling upon Grams for Chris' wiccaning, she quickly grows tired of Wyatt and Chris' constant bickering and sibling rivalry, and casts a spell to put an end to it. However, her spells moves the bickering to the closest siblings in the area: Piper, Phoebe and Paige. As a result, the sisters revert to their teenage ways and cause Grams and Victor to find a way to rapidly reverse the spell, especially after a demon attacked Wyatt.
