Charmed, Season 3

(Piper and Phoebe blink from the kitchen into the living room)

Piper:
Catch us if you can!

Phoebe:
Have you tried it yet, Leo? It's a real head rush.

Leo:
Do you realize how serious this is? You're blinking, the Book is changing.

Piper:
Maybe we're blinking because of the Book.

Leo:
The Book is changing because of you. It is an extension of you.

Piper:
I should care about that--but I don't.

Leo:
This is what I was afraid of. Whoever's got Prue is somehow reaching you too.

Phoebe:
Okay Leo, I can tell this really upsets you, but I gotta tell you, I really like this whole 'think it and it happens' deal. I mean, just think of the time we could save not chanting!
