Doc: The time-traveling is just too dangerous. Better that I devote myself to study the other great mystery of the universe: women!

Marty McFly: Where are we? When are we?
Doc: We're descending toward Hill Valley, California, at 4:29 pm, on Wednesday, October 21st, 2015.
Marty McFly: 2015? You mean we're in the future?
Jennifer: Future? Marty, what do you mean? How can we be in the future?
Marty McFly: Uh, Jennifer,

um, I don't know how to tell you this, but I... you're in a time machine.
Jennifer: And this is the year '2015'?
Doc: October 21st, 2015.

[Doc and Marty in the time machine are about to depart from the Alternate 1985]
Doc: Time circuits on.
Marty McFly: What do you mean "Time Circuits on"? Doc, we're not goin' back now!
Doc: Yep.
Marty McFly: Doc, What about Jennifer? What about Einstein? We can't just leave 'em here.

Doc: Don't worry, Marty. Assuming we succeed in our mission, this alternate 1985 will be changed back into the real 1985, instantaneously transforming around Jennifer and Einie. Jennifer and Einie will be fine, and they will have absolutely no memory of this horrible place.
Marty McFly: Doc... what if we don't succeed?
Doc: We *must*

succeed.

Old Biff: You always did have a way with women.
Young Biff: Get the hell out of my car, old man!
Old Biff: You wanna marry that girl, Biff? I can help make it happen.
Young Biff: Oh-oh, yeah, who are you, Miss Lonelyhearts?
Old Biff: Just get in the car, Butthead.
Young

Biff: Who you callin' "butthead", Butthead?
[Old Biff starts the car]
Young Biff: How do you know how to do that? Nobody can start this car but me.
Old Biff: Just get in the car, Tannen. Today's your lucky day.

Young Biff: Why don't you make like a tree and get out of here?
Old Biff: It's *leave*, you idiot! "Make like a tree, and leave." You sound like a damn fool when you say it wrong.
Young Biff: All right then, LEAVE! And take your book with you!

Young Doc: No! It can't be; I just sent you back to the future!
Marty McFly: No, I know; you *did* send me back to the future. But I'm back - I'm back *from* the future.
Young Doc: Great Scott!
[Doc faints]
Marty McFly: Doc! Doc! Doc! Oh, fantastic.

[Flying above Biff in 1955]
Marty McFly: There he is, Doc! Let's land on him, we'll cripple his car.
Doc: Marty, he's in a '46 Ford, we're in a DeLorean. He'd rip through us like we were tin foil.

Doc: They're taking her home, to your future home! We'll arrive shortly thereafter, get her out of there and go back to 1985.
Marty McFly: You mean, I'm gonna see where I live? I'm gonna see myself as an old man?
Doc: No, no, no Marty, that could result in a-
[gasps]
Doc: Great Scott! Jennifer could

conceivably encounter her future self! The consequences of that could be disastrous!
Marty McFly: Doc, what do you mean?
Doc: I foresee two possibilities. One, coming face to face with herself 30 years older would put her into shock and she'd 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 a worse case scenario. The destruction might in fact be very localized, limited to merely our own galaxy.
Marty McFly: Well, that's a relief.

Marty McFly: That's right, Doc. November 12, 1955.
Doc: Unbelievable, that old Biff could have chosen that particular date. It could mean that that point in time inherently contains some sort of cosmic significance. Almost as if it were the temporal junction point for the entire space-time continuum. On the other hand, it could just be an amazing

coincidence.

Marty McFly: I don't get it, Doc. I mean, how can all this be happening? It's like we're in Hell or something.
Doc: No, it's Hill Valley. Although I can't imagine Hell being much worse!

Doc: [on walkie talkie to Marty] Then get outta there!
Marty McFly: [on walkie-talkie] No, Doc. Not *me*, the *other* me, the one that's up on stage playing "Johnny B. Goode."!
Doc: [on walkie-talkie]

Great Scott! Your other self will miss the lightning bolt, you won't get back to the future and we'll have a major paradox!

Marty McFly: [Reading the newspaper from 2015] "Within two hours of his arrest, Martin McFly Jr. was tried, convicted and sentenced to fifteen years in the state penitentiary."? Within two hours?
Doc: The justice system works swiftly in the future now that they've abolished all lawyers.

Middle-Aged Marty: Hey, Needles.
Needles: So, did you take a look at that little business proposal of mine?
Middle-Aged Marty: I don't know, Needles.
Needles: What are you afraid of? If this thing works it'll solve all your financial problems.
Middle-Aged

Marty: And if it doesn't work Needles, I could get fired! It's *illegal*! I mean, what if the Jitz is monitoring, huh?
Needles: The Jitz'll never find out!
Middle-Aged Marty: Oh, ha, ha.
Needles: Come on... Stick your card in the slot and I'll handle it. Unless you want everyone in the division to think you're

*chicken*.
Middle-Aged Marty: [angrily] Nobody calls me 'chicken', Needles. Nobody!
Needles: All right, prove it.
Middle-Aged Marty: All right, all right Needles. Here's my card. Scan it, I'm in.
Needles: Thanks McFly, I'll see you at the plant tomorrow.

Marty McFly: The almanac. Son of a bitch stole my idea! He must have been listening when I- It's my fault! The whole thing is my fault. If I hadn't bought that damn book, none of this would have ever happened.
Doc: Well, that's all in the past.
Marty McFly: You mean the future.
Doc: Whatever! It demonstrates

precisely how time travel can be mis-used, and why the time machine must be destroyed, after we straighten all of this out.

Marty McFly: What about the police, Biff? They're gonna match up the bullet with that gun.
Biff Tannen: Kid, I own the police! Besides, they couldn't match up the bullet that killed your old man.
Marty McFly: You son of a...
[Biff cocks the gun]
Biff Tannen: I suppose it's poetic justice - two McFlys

with the same gun.
