WILLOW: I don't know where to start. Um, after Warren shot you?you know all about that, what happened? It was horrible. I was horrible. I?I lost myself, the regular me.

CASSIE: Well, you were grieving.

WILLOW: A lot of people grieve. They don't make with the flaying. I hurt so many people.

CASSIE: It was the power.

WILLOW: I am the power. It's in me. Did I mention the random destruction of property? The Magic Box is not so much a box now?

CASSIE: The power is bigger than you are.

WILLOW: I know, but?

CASSIE: Things are more clear where Tara is, where we are. We can see your path, and you have to stop. You can't use magic again, not ever.

WILLOW: Black magic, of course. But Giles says it isn't as simple as-as quitting it all cold-turkey?

CASSIE: It's too dangerous. You can't take the chance that you'll lose control.

WILLOW: I-I don't want to. I-I can't. I never want to cause that kind of pain.

CASSIE: Of course you don't.

WILLOW: So, I won't. I'm gonna be OK.

CASSIE: She says...

WILLOW: What?

CASSIE: You're not gonna be OK. You're gonna kill everybody.
