(Angel storms into the lab)

ANGEL: (ranting) Illyria's blown all of her gaskets, man. She's outta her mind.

SPIKE: How can you tell? Yesterday she spent 2 hours mind-melding with a potted fern.

ANGEL: She thinks I'm trying to kill her.

WESLEY: Aren't you?

ANGEL: Tell me you have something, Wes. Just anything.

WESLEY: She is unstable. Overloading, to be more accurate. The fusion between her demon essence and her host's body seems to be deteriorating. It's as if the human part of her can no longer contain the demonic power within.

SPIKE: Hmm. We're thinking that she cracked her engine block and now she's leakin' petrol all over the building.

WESLEY: She's going to self-destruct, violently, and soon.

ANGEL: And you were gonna tell me this when?

WESLEY: I wasn't. Spike and I were dealing with it.

SPIKE: We're motivated go-getters.

WESLEY: The good news is the crack in her engine block may give us a chance to get to her.

(he takes a large metallic weapon out of the box on the table)

WESLEY: This is a Mutari generator. It creates a pinhole to an infinite extra-dimensional space, a negatively charged pocket universe, that should draw her radiant essence, her power, into itself, by process of a--

ANGEL: Wes. Will it kill her?

WESLEY: Yes. (to Spike) Shall we go?

ANGEL: We have to find out where she--

(Spike grabs the laptop, shows the display to Angel)

SPIKE: Oh, here.

(the display shows a blue dot moving through a map of the building)

SPIKE: Training room, looks like. And gushin' petrol like a geyser.

(the three walk to the training room)

SPIKE: So what sort of damage are we lookin' at if Illyria Chernobyls on us?

WESLEY: Conservative guess, several city blocks.

ANGEL: And what about unconservative?

WESLEY: Rand and McNally will have to redraw their maps.

(Lorne is loitering outside the room)

ANGEL: (to Lorne) Is she in there?

LORNE: (scoffs, holding up the walkie-talkie) Do you even know how to use this thing?

(follows them inside; the training room is empty)

LORNE: That's funny. I didn't even see her leave.

SPIKE: (shrugs) Well, that's the problem. You don't always see her when she's--

(he explodes into ash, revealing that Illyria has just staked him)

WESLEY: Illyria!

ANGEL: Wes, do it now. (he charges Illyria)

(a fight breaks out, during which Illyria kills first Wes, then Lorne, and finally dusts Angel. She stands alone in the room, smiling. cut to commercial, resume, and she doubles over in pain again, this time finding herself back in the hallway talking to Angel when she straightens)
