YMMV / Charmed S1E7 The Fourth Sister

• Hilarious in Hindsight: The title of this episode becomes this in season 4, where Piper and Phoebe learn they do in fact have another sister.
• Les Yay: Aviva persuades Phoebe to take her up to her bedroom by offering to show her magic in a very flirtatious way, even saying "I'll show you my power, if you show me yours". It's no wonder Leo thought they were a couple.
