Against Piper's wishes, Paige and Phoebe summon Grams for Chris's 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 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, only to end up acting like a love-struck teenager.
