Doc: Why yes, yes of course! Because this hoverboard incident has now occurred, Griff goes to jail. Therefore your son won't go with him tonight and that robbery will never take place. Thus history, future history, has now been altered and this is the proof! Marty, we've succeeded, not exactly as I'd planned but no matter. Let's go get Jennifer and go home!
Marty: Hi Einie, hi buddy!
Doc: What's this?
Marty: Uh, it's a souvenir...
Doc: 50 years of Sports Statistics. Hardly recreational reading material Marty.
Marty: Hey Doc, what's the harm of bringing back, er, a little info on the future? Thought maybe we could place a couple of bets.
Doc: Marty! I didn't invent the time machine for financial gain. The intent here is to gain a clear perception of humanity. Where we've been, where we're going. The pitfalls and the possibilities. The perils and the promise. Perhaps even an answer to that universal question, why?
Marty: Hey Doc, I'm all for that! What's wrong with making a few bucks on the side?
Doc: I'm going to put this in the trash!
Doc: Great Scott!
Officer Reese: McFly, Jennifer Jane Parker. 3793 Oakhurst St, Hilldale. Age 47.
Officer Foley: 47? That's a hell of a good facelift.
Marty: What the hell are they doing Doc?
Doc: They used her thumbprint to assess her ID. Since her thumbprint never changes over the years they simply assume she's the Jennifer of the future.
Marty: Well, we gotta stop them!
Doc: What are we going to say, that we're time travellers? Hey, they'd have us committed.
Officer Foley: She's clean, that means we take her home.
Officer Reese: Home, to Hilldale? It'll be dark by the time we get out there.
Doc: They're taking her home, to your future home! We'll arrive shortly thereafter and get her out of there and go back to 1985.
Marty: You mean I'm going to see where I live? I'm going to see myself as an old man?
Doc: No, no, no Marty, that could resolve in a.....
Marty: Doc, what do you mean?
Doc: I foresee two possibilities. One - coming face-to-face with herself thirty years older could put her into shock and she could simply pass out. Or two - the encounter could create a time paradox, the results of which could cause a chain reaction that would unravel the very fabric of the space-time continuum and destroy the entire universe. Granted, that's the worse case scenario. The destruction might, in fact, be very localised, limited to merely our own galaxy.
Marty:
Doc: Let's go, I sure hope we find Jennifer before she finds herself!
Doc: Damn, the skyway's jammed, it's going to take us forever to get there.
Marty: I know, I know Doc!
Biff: So, Doc Brown invented a time machine.
Officer Reese: Hilldale. Nothing but a breeding ground for tranqs, lobos and zipheads.
Officer Foley: Yeah, they ought to tear this whole place down.
Computerised Voice:
Jennifer: What?
Officer Reese: You got a little tranked, but I think you can walk.
Officer Foley: Ma'am, you should reprogram, it's dangerous to enter without lights on.
Jennifer: Lights on?
Officer Foley: yes, now look. Just take it easy and you'll be fine. And be careful in the future.
Jennifer: Future?
Officer Foley: Have a nice day Mrs McFly.
Computerised Voice:
Jennifer: I'm in the future.
Marlene:
Jennifer:
Marlene: Mom? Mom, is that you?
Marlene: Grandma Lorraine!
Lorraine: Sweetheart!
Marlene: What happened to Grandpa?
Lorraine: Oh, he put his back out again.
George: How's Grandad's little pumpkin?
