S07E03: Cheaper by the Coven (Remastered)

Against Piper's wishes, Paige and Phoebe summon Grams for Chris' wiccaning that will protect him from evil while he grows. However, Wyatt gets attacked in the nursery by a masked demon that Leo begins pursuing with single-minded abandon and resolve. Meanwhile, Wyatt feels threatened that his younger brother is getting all of the attention and uses magic on him. In order to prevent sibling rivalry, Grams casts a spell on Wyatt and Chris, but inadvertently makes the sisters act like teenagers again. The Charmed Ones father, Victor, comes to the house and he decides to summon Patty to help him reverse the spell.
