In the hellmouth. Spike's amulet id charging up, surrounding him in a golden light...
(You know all of the dialog at this point. No reason to repeat it. Fast forward to...)
Buffy-- I love you.
Spike-- No, you don't. But thanks for saying it.
Buffy-- Say WHAT? Three years, you've been telling me that you love me, and that I really love you, but I'm just afraid to say so. Now I finally get up the courage to actually say the words, and all I get is "No, you don't," and now what? I'm supposed to go scampering out the tunnel mouth and leave you here to die? Not on your life, buster. This little girl ain't goin' anywhere without her man.
Faith (From the tunnel mouth)-- Buffy!
Buffy (Shouting over her shoulder without taking her eyes off of Spike)-- You go ahead. I'm staying here with the man I love. You're Mama Slayer now.
Faith (Runs back down to where the two are holding hands. Spike is tugging, trying to break Buffy's grip. Buffy squeezes harder)-- You're really staying here? Well, does that mean that I get the scythe? (She reaches for it. Buffy releases her grip on the weapon) So, let me get this straight. You're gonna stay here with Pretty Boy, and leave me to run that bunch of little girls who just got Slayer-ized. Is that your plan?
Buffy-- Right. If Spike stays, I'm staying.
Faith (dodging a falling piece of stone)-- Oh, hell no you're not! (She swings the Scythe, the flat of the blade connecting solidly with Spike's skull. He drops to the cavern floor, unconscious. Faith tosses Buffy the scythe, reaches down, lifts Spike and tosses him across her shoulder) Now, B, get your ass out of here, and make it fast, because me and Stud Muffin are gonna be right behind you.
Buffy (With tears in her eyes)-- Oh, thank you. I didn't know what I was going to...
Faith-- SHUT UP AND GET MOVING, DAMMIT!
The two Slayers make it to the bus just as it is pulling out. They toss Spike in the back, cover him with a blanket, and run back to the front, where Wood is patiently bleeding all over the driver's seat.
Faith-- That's everybody. Let's move it.
Wood-- I can't...
Faith-- I didn't think you were hurt that badly.
Wood-- It's not tht. I CAN'T DRIVE STICK!
Faith yanks Wood roughly out of the seat, sits down, starts the bus, and they peel out, just as Sunnydale begins collapsing behind them. The race is close, the fissure getting closer and closer.
Faith-- We're never gonna make it. This bus is too heavily loaded...
Before she gets the chance to finish, Giles jumps up, yells "It's for the greater good!" and dives out the window. Andrew follows suit, yelling "Avengers Assemble!" Dawn is right behind him. "I'll do the dying this time!" and she's gone. Then Willow yells, "It's for the best!" and throws Kennedy out the back door.
With its load lightened, the bus manages to increase its speed just enough to barely escape the collapse of Sunnydale before the overworked engine gives out with a shudder and coasts slowly to a stop. The survivors climb out and look back at the huge hole that was once Sunnydale, stunned.
Faith-- We did it, B. We did it and got out alive, to boot. What're you gonna do now? You can start lining like a real person.
Buffy (Wiping sweat and blood out of her eyes.)-- I'm planning on going to bed for about a month.
Faith-- Well, first we've gotta take care of Sp... (Realization strikes)
Buffy (With a smug look on her face, nods, looking back toward the bus)-- Spike.
