The Charmed Ones are given their first Homeland Security case by Agent Murphy (guest star Brandon Quinn) going through cold case files. Phoebe (Alyssa Milano) and Billie (Kaley Cuoco) discover a belt in one file that gives Billie superpowers. Her new power begins turning the sexes on one another, so a power-hungry female demon decides to use Billie to achieve female domination. Meanwhile, Piper (Holly Marie Combs) and Leo (Brian Krause) search for a band to play at the club and sparks fly between Paige (Rose McGowen) and her new charge's parole officer, Henry (guest star Ivan Sergei).

LeVar Burton directed the episode written by Jeannine Renshaw.

You need to catch up, Cory

Billie is a new witch - and at first the girls took her under their wing and promised to teach her more witchcraft as long as she kept the secret of their identities. The girls grew attached to her and now they're more like a family. It's hard to explain Billie, really... if you want, I can send you some of the episodes, I have them on my computer

Yeah, she's just another witch - apparently, one Paige is supposed to guide. And she showed up in the premiere of season eight, so she's a regular.

Actually, I think it was Paige who was led to her... you know, magically.

Very good!
