Paige thinks Dex is cheating on Phoebe and, despite Phoebe's protests, starts spying on him. Leo takes over Billie's training, and she insists on going to Magic School, but once they get there, they find the place crawling with demons. While preparing for Wyatt's school play, Piper tries to outdo another mom, Mandi. Mandi turns out to be possessed by a demon who wants to raise Wyatt as her own son.
Tropes
- Big Bad Wannabe: The demon possessing Mandi has the ambition. She sees getting in good with the revived Source and taking on Wyatt as a surrogate child as the means to achieve Big Bad status.
- Continuity Nod:
- Leo and Billie blend in by knocking out two demons and stealing their clothes, just like Leo did in Apocalypse, Not.
- Leo tries to sound like a credible demon by saying he worked for Zankou.
- Flanderization: The Source is noticeably hammier than his last appearance.
- No Ontological Inertia: As threatening as the prospect of the Source being back is, Piper gets rid of him simply by vanquishing the demon who summoned him.
- Oh, Crap!: The Source when "Mandi" tells him Wyatt has Charmed power.
- The Only One Allowed to Defeat You: Implied. The Source is not thrilled to learn the Charmed Ones are apparently dead.
- Papa Wolf: Leo botches his cover largely because he doesn't like the Source getting near Wyatt.
- Properly Paranoid:
- Piper thinks Mandi is out to get her, which Leo immediately dismisses. Turns out she is right.
- The Source realizes Leo's identity by noticing how Wyatt keeps hanging around him.
- Series Continuity Error: Paige asks Phoebe and Piper how they vanquished the Source as if she wasn't there when it happened, despite the fact that she was there.
