TEXT: [PREVIOUSLY_ON] Leo: I should have gone taller. I always wanted to be taller. Why'd you go blond? Piper: I don't know. I didn't have a lot of time to think about it. Piper: They think I'm somebody else. Paige: You are somebody else. Piper: But I'm not a fugitive. This is not the alias that I picked, at least, not intentionally. Paige: So, missy, where are you gonna get your next alias from? Time magazine? Piper: I came up with this one on my own, thank you. Paige: Well, just make sure it's not off the most wanted list. Piper: Trust me. Dex: Dex Lawson. Phoebe: Nice to meet you, Dex. Dex: You, too. Piper: So, what happened to the demon? Paige: I don't know. This chick came along and scared him off. Piper & Phoebe: What chick? Billie: I'm here because you need me, right? So the more you teach me, the more I can get out there and go kick some demon ass. Paige: We want to keep the use of magic to a minimum so the demons don't find out we're still alive. [SCENE_BREAK] Leo: Knowing how untrained and untethered magic could lead to disaster, the one in Atlantis being the prime example, the elders they knew that they needed to nurture young magic. The elders knew they needed to nurture young magic. Billie. Billie, are you listening to me? Billie: Yeah, yeah, yeah. Untethered magic, elders, yada-yada-yada. Leo: Okay, listen, if you're gonna take over the fight for the greater good, I really don't think it's a bad idea if you know the history of good magic. Listen, Paige wanted me to teach you something good, and I think you're kind of making me look bad right now.
SUMMARY:
Wyatt's school play Cinderella brings out the competitive nature in Piper when her hand-sewn costume and parenting abilities are criticized by another mother. Things go from bad to worse when it is revealed that this Stepford-wife-like "Oh-so-perfect" mother is in fact possessed by a demoness focused on kidnapping Piper's son Wyatt and using him in a plot with other demons to resurrect the Source of All Evil at Magic School ; which the demons have forcibly taken possession of after the (believed and faked) deaths of the three Charmed Ones. Meanwhile, Paige sees Dex with another woman, who turns out to be his ex-girlfriend who is a compulsive liar, and despite Phoebe's objections, interferes by masquerading as the woman and expecting evidence Dex is two-timing Phoebe. Dex apologizes to Phoebe after Paige commits her interfering faux pas and her masquerade crashes, saying he probably shouldn't have stayed in touch with and should have made a more complete break with his old girl earning points for earnestness and honesty. Meanwhile, Billie and Leo sniff out the plot at magic school and research a spell to return Billie to our world for power-of-three reinforcements while Leo stays nearby with Wyatt who has accompanied the possessed mother there. With Wyatts powerful help, the demoness has conjured the source who appears to be fully resurrected and ready to take command again in the Underworld. Billie's timely return with Paige, Phoebe and Piper enables the three to intervene in the demon's festivities. Piper vanquishes both threats by dealing with the demoness-who has linked the two by her conjuration of the source which consequently was not as powerful and troublesome as the original incarnation of source because the magical link to the demoness gave it a new vulnerability.
