Buffy the Vampire Slayer, Season 7

Giles:
We're back at square one.

Xander:
Which square would that be, exactly?

Giles:
I'm not sure. The First predates everything we've ever known. Or can know. It's everywhere, it's pure. I don't know if we can fight it.

Buffy:
You're right. We don't know how to fight it. We don't know when it'll come. [We] can't run, can't hide... can't pretend it's not the end 'cause it is. Something has always... been there to try and destroy the world. We've... beaten them back, but we're not dealing with them anymore. We're dealing with the reason they exist. Evil. The strongest. The First.

Giles:
Buffy, I, um... I-I know you're... you're tired...

Buffy:
I'm beyond tired. I'm beyond scared. [near sobbing] I'm standing on the mouth of Hell and it is going to swallow me whole. [hardens] And it'll choke on me. We're not ready? They're not ready. They think we're gonna wait for the end to come, like we always do. I'm done waiting. They want an apocalypse? Well, we'll give 'em one. Anyone else who wants to run, do it now, 'cause we just became an army. We just declared war. From now on, we won't just face our worst fears, we will seek them out. We will find them, and cut out their hearts, one by one, until the First shows itself for what it really is. And I'll kill it myself. There is only one thing on this earth more powerful than evil. And that's us. Any questions?
