FRED: Spike. What are you...can I help you?

SPIKE: Well, that's the heart of it, isn't it? The crux. The nub.

FRED: I'm sorry?

SPIKE: You're the smart one, aren't you? The go-to girl who knows all about this ghost mumbo-jumbo.

FRED: Um... Well, actually, Wesley's the occult expert. He—he was trained as a Watcher. He knows about the supernatur—

SPIKE: Yeah, but you're the science queen. The hows, the what-ifs. That's your cup of tea. You figure things out in that cute little noggin of yours.

FRED: (nervously) I guess. What... I-is there something...

(Spike laughs ironically)

SPIKE: I'm slippin'.

FRED: What?

SPIKE: Don't wanna go, but it's like... It's like the ground underneath me is... splitting open and my legs are... straddling both sides of this bloody big chasm. It's getting wider, pulling me in.

FRED: Is that... is that what's happening when you keep vanishing?

SPIKE: I know what's down there—where it's trying to take me—and it's not the place heroes go. Not by a bloody long shot. It's the other one. Full of fire and torment. And it's happening. And I'm terrified. Help me?
