Jennifer: I wonder where we live, I bet its a big house, with lots of kids. How many kids.....
Doc gets out a gadget and shines it on Jennifer. She falls back, unconscious.
Marty: Doc, what the hell are you doing?
Doc: Relax Marty, it's a sleep-induced alpha-rhythm generator. She was asking too many questions and no-one should know too much about their future.
Marty feels Jennifer's face.
Marty: Then what did you bring her for?
Doc: I had to do something! She saw the time machine, I couldn't just leave her there with that information. Don't worry, she's not essential to my plan.
Marty: You're the Doc, Doc.
Doc: Here's our exit.
The DeLorean leaves the skyway. Sign in the background says "Phoenix : Boston : London" and underneath "Local traffic: Hill Valley exit next right." After leaving the skyway it passes a floating sign, "Welcome to Hill Valley. Mayor Goldie Wilson II. A nice place to live. Please fly carefully." The DeLorean descends down into Hill Valley. Cut to an alleyway, where the DeLorean lands. Laser discs and a "Fusion Industries" generator are in the background. Doc opens the DeLorean doors.
Doc: First you gotta get out and change clothes.
Marty: Right now? It's pouring rain.
Doc looks at his watch.
Doc: Wait five more seconds.
The rain stops in exactly five seconds.
Doc: Right on the tick. Amazing. Absolutely amazing. Too bad the post office isn't as efficient as the weather service.
Marty and Doc get out of the DeLorean. Doc's wearing a rubber mask! He starts peeling it off.
Doc: Excuse the disguise, Marty, but I was afraid you wouldn't recognise me. I went to a rejuvenation clinic and got an all-natural overhaul. They took out some wrinkles, did a hair repair, changed the blood - added a good thirty or forty years to my life. They also replaced my spleen and colon. What do you think?
Doc "models" his new face.
Marty: You look great, Doc.
Marty looks around.
Marty: (mutters to himself) The future.....unbelievable..... (to Doc) I gotta check this out Doc.
Doc: All in good time Marty, we're on a tight schedule here.
Marty: Tell me about my future. I mean, I know I make it big, but what do I become like a rich rock star or something?
Doc: Please Marty, no-one should know too much about their own destiny.
Marty: Right, right.....I am rich though?
Doc gets a bag out of the DeLorean.
Doc: Marty, please, take off your shirt.
Marty does so.
Doc: Put on the jacket and shoes.
Doc goes into the car and gets out a pair of futuristic binoculars. It looks a bit like a very thin camera.
Doc: We've got a mission to accomplish!
He runs to the end of the alleyway and uses this gadget. Cut to a street. Doc looks at a woman walking down it, then MARTY MCFLY JUNIOR walks past her. Doc uses the gadget to watch Marty Junior, who looks almost like his father aged 17 (ie 1985 Marty) walk into a futuristic 'phone box.
Doc: (muttering) Precisely on schedule.
Cut to Marty. He's go the shoes out of the bag and put the right one on his foot. It automatically laces up!
Marty: Power laces, all right!
He puts on the left shoe and it does the same thing. Marty then gets the jacket out of the bag and puts it on. It's a bit big! Cut to Doc running back towards Marty. Marty's jacket has a little button on it that flashes.
Marty: This thing doesn't fit.
Doc presses the button. The jacket modifies so it fits Marty.
Computerised Voice in Jacket: (v.o) Size adjusting, fits.
Doc: Pull out your pants pockets. All kids in the future wear their pants inside out.
Marty does so. Doc goes back into the bag and pulls out a cap.
Doc: Put this on.
Doc puts it on Marty's head.
Doc: Perfect, you're the spitting image of your future son.
Marty: What?
Doc: Help me move Jennifer over here!
Marty and Doc lift Jennifer out of the DeLorean.
Marty: So what's the deal?
