Charmed - Episode 614 - The Legend of Sleepy Halliwell

Leo's (Brian Kruause) old mentor at Magic School, Gideon (guest star Gildart Jackson), calls upon Piper (Holly Marie Combs), Phoebe (Alyssa Milano) and Paige (Rose McGowan) to find out who cast the spell of darkness upon the school and conjured up the Headless Horseman, who has been beheading the teachers. Meanwhile, Phoebe is sent on a vision quest by Enola (guest star Elena Finney), a young shaman student, and gets a glimpse into the future, where she discovers Chris' (Drew Fuller) true identity.

Phoebe: "Are you Wyatt's little brother?"

Chris: "...Only if I can get Piper and Leo back together in time."

Phoebe's head (to Paige and Piper's heads): "So lets just put our heads together and ...you know what I mean, right?"

Piper (after having her head cut off): "Great. Just great."

Piper's head: "Don't give me that look. I still got a mouth. I could turn you into a toad."
