Charmed - Episode 806 - Kill Billie: Vol. 1

Armed and ready to vanquish, Billie (Kaley Cuoco) inexplicably freezes and is flooded with childhood flashbacks when she sees her latest demon target, The Dogan (guest star Eric Steinberg). Wanting to prove to the sisters that she is an asset, Billie casts a spell to erase her fears and goes after the demon. However, when the spell doesn't work, Billie opens up to the sisters and relives her painful childhood memory of the long-ago Halloween when her sister was kidnapped by a demon. Meanwhile, since announcing their involvement with Homeland Security, the sisters have been bombarded by the press. Wanting to put a stop to it, Paige turns to the Elders for help. After telling Dex (guest star Jason Lewis) that she is a witch, Phoebe and Dex realize that their relationship is moving too fast and decide to slow things down - without the help of magic. Leo confronts Piper on being Mr. Mom.

Billie (about vanquishing the Dogan): Please I know I can do this.
Piper: Fine, but if you get caught on tape I will vanquish you.
Billie (to Paige): She's serious?
Paige: Eh uh...just don't get caught.
