Disclaimer: I don`t own anything to BTTF.

Oh, and sorry this took me like forever. I had failing grades, again, but it`s all good now!

Marty was walking a block past Maple St, until he saw Doc`s house.

"Doc!" Marty called as he knocked on the door.

He listened for a minute, then continued yelling, "Doc, Doc, please answer me!" he called out desperately.

He listened again. Still no answer.

He started to turn around, until he heard the door open.

"Doc?" Marty wondered out loud as he turned around, but the door had already closed.

Frustrated, Marty knocked once again.

"Doc!"

Then finally the door opened, revealing a mid-thirties Doc.

"Don`t say a word." Doc said as he pulled him in.

"Doc!" Marty said.

"I don`t want to know your name. I don`t want to know anything about you!" Doc said hastily.

"Listen, Doc." Marty begged.

"Quiet."

"Doc, Doc, it`s me, Marty. Doc, you gotta help me-" Marty started but was cut off when Doc put one of his experiments on his forehead.

"I`m gonna read your thoughts." Doc said to him.

The mind reading helmet said the words, "Great distance."

"Let`s see now, you come here, from a great distance?" Doc guessed.

"Yes, exactly!"

"Don`t tell me!" Doc said, annoyed.

The word, "subscription" came up.

"Uh, you want me to buy a subscription to the Saturday Evening Post?" Doc guessed, hoping that he was right.

"No!" Marty said, frustrated that Doc wouldn`t listen.

"Not a word, now a word now!"

"How in the name of Sir. Isaac Newton could I be incorrect about that? Damn experiment!" Doc thought to himself, as he hoped that he would get this one correct.

The word, "donations" came up.

"Donations. You want me to make a donation, to the Coast Guard Youth Auxilary?" Doc guessed once again, mainly because of this boy`s weird clothing.

"Doc!" Marty said in frustration.

"I`m from the future. I came here in a time machine that you invented. Now I need your help to get back to the year, 1985." Marty explained thouroughly.

"My God, do you know what this means?" Doc asked, taking ahold of Marty`s shoulders.

"It means that this damn thing doesn`t work at all! 6 months of work!" Doc yelled angrily.

"Doc, you gotta help me. You are the only one who knows how your time machine works." Marty explained once again.

"Time machine, I haven`t invented any time machine."

For a second, Marty thought he had actually believed him, but he saw that Doc went back to pick up his supplies.

"Okay, alright, I`ll prove it to you." Marty said as he pulled out his wallet and driver`s license.

"Look at my driver`s license, expires 1987. Look at my birthday, for crying out loud, I haven`t even been born yet!" Marty proved, as he took out a picture.

"And look at this picture, my brother, my sister, and me. Look at her sweatshirt Doc, class of 1984!"

But Doc still didn`t believe him.

"Pretty mediocre photographic fakery, they cut off your brother`s hair."

"I`m telling the truth Doc, you gotta believe me." Marty hoped, deperately.

"So tell me, Future Boy, who`s President of the United States, in 1985?" Doc asked curiously with a tone of sarcasm.

"Ronald Reagan."

"Ronald Reagan? The actor?!" Doc repeated in disbelief.

"Then who`s Vice President, Jerry Lewis?" Doc joked sarcastically, before leaving.

"I suppose Jane Wyman, is the First Lady!"

"Whoa, wait Doc!" Marty called.

"And Jack Benny, is Secretary of the Treasury?" Doc added sarcastically.

"Doc, you gotta listen to me!" Marty pleaded.

"I`ve had enough practical jokes for one evening. Good night, Future Boy!" Doc said, slamming the door.

"Wait, Doc the bruise!" Marty remembered. "The bruise on your head, I know how that happened, you told me the whole story. You were standing on your toilet and you were hanging a clock, you fell, and you hit your head on the sink. And that`s when you came up with the idea for the flux capacitor, which, is what, makes time travel possible." Marty concluded, turning to leave.

Then the door opened. "How do you know that story?" Doc wondered, half whispering.

"You told me before, in 1985." Marty said, knowing that would prove it.

This stunned Doc too much. "Come inside."

"So, what you`re telling me is, that you came here, in a vehicle called a DeLorean?" Doc asked, sipping his cup of tea.

"Yes, exactly, and I need your help to get back."

There was a brief moment of silence, until Doc asked, "Take me to the, DeLorean."

__________________________________________________________________________________

As soon as they got to Lyon Estates, they found the DeLorean, underneath a branch.

"There`s something wrong with the starter, so I hid it, here." Marty explained.

"After I fell off my toilet, I drew this." Doc said, showing a rumpled paper drawing of the flux capacitor.

"The Flux Capacitor."

Then Doc turned on the switch.

"It works? It works!" Doc cheered with pleasure. Grabbing Marty`s shoulders, he said happily, "I finally invent something that works!"

"You bet your ass it works." Marty muttered.

But Doc didn`t seem to hear him. "Somehow we gotta sneak this back into my labratory. We`ve gotta get you home!"

__________________________________________________________________________________

"Okay, Doc, this is it." Marty said, showing him the video tape they had made earlier.

Marty had explained that they had made a video of him, that explained about the DeLorean.

"Never mind that, never mind that now." the Video Doc said.

"Why that`s me! Look at me, I`m an old man!" Doc yelled surprisingly.

"Good evening, I`m Dr. Emmett Brown, I`m standing here on the parking lot of Twin Pines Mall, it`s Saturday morning, October 26th, 1985."

"Thank God I still got my hair!" Doc cheered again as he was still overwhelmed by the fact that he had aged. "What on Earth is that thing I`m wearing?"

"Well, that`s a radiation suit." Marty replied.

"Radiation suit, of course! Because of the fall out from the atomic wars. This, is truly amazing." Doc said, observing the video camera. "A portable television studio. No wonder your President has to be an actor, he`s gotta look good on television."

"Whoa, this is it, this is the part coming up, Doc." Marty said, replaying the tape.

"No, no, this sucker`s electrical, but I need a nuclear reaction to generate the 1.21 jigowatts of electricity I need."

"What did I just say?" Doc demanded hastily, who obviously didn`t hear it.

"No, no, this sucker`s electrical, but I need a nuclear reaction to generate the 1.21 jigowatts of electricity I need."

Stunned, Doc arose. "1.21 jigowatts?!"

"1.21 jigowatts." he muttered in disbelief as he ran into the living room.

"Great Scott!!"

Confused, Marty followed him. "What the hell is a jigowatt?"

There, he found Doc on the couch, with his head on his hands.

"How could I have been so careless? 1.21 jigowatts. Tom? How am I gonna generate that kind of power? It can`t be done, can it?"

"Doc, look, all we need is a little plutonium!" Marty explained as if you could buy it at a drugstore.

"Ohh! I`m sure that in 1985, plutonium is available at every corner drug store, but in 1955, it`s a little hard to come by. Marty, I`m sorry, but I`m afraid you`re stuck here." Doc said, ashamed that he can`t help the teenager.

"Whoa, whoa Doc, stuck here? I can`t be stuck here. I got a life, in 1985! I got a girl!" Marty explained.

"Is she pretty?" Doc wondered as it was the first thing that came into his mind.

"Doc, she`s beautiful. She`s crazy about me. Look at this, look what she wrote me, Doc. That says it all." Marty said, showing him what she had wrote on the back of the flyer.

"Marty, I`m sorry, but the only power source capable of generating 1.21 jigowatts of electricity is a bolt of lightning."

"What did you say?"

"A bolt of lightning. Unfortunately, you never know when or where, it`s ever gonna strike!"

Realizing about the lighting storm and the flyer, Marty quickly pulled it back out.

"We do now." he said as he showed him the flyer.

Grabbing it, Doc quickly scanned it. "This is it! This is the answer. It says here that a bolt of lightning is gonna strike the Clock Tower precisely at 10:04 pm, next Saturday night! If we could somehow, harness this lightning, channel it, into the flux capacitor, it just might work. Next Saturday night, we`re sending you back to the future!" Doc concluded happily.

"Okay, alright, Saturday is good, I could spend a week in 1955. I could hang out, you could show me around.."

"Marty, that`s completely out of the question, you must not leave this house. You must not see anybody of talk to anybody. Anything you do could have serious replications on future events. Do you understand?"

Remembering that he had talked to his parents before, he didn`t even know he could actually alter it. How could he have been so stupid?

"Yeah, sure." Marty replied, weakly.

"Marty." Doc said, grabbing his shoulders, obviously thinking that he had done something. "Have you interacted with anybody else today, besides me?"

"Well, yeah, I might have sort of, bumped into my parents." Marty replied, once again, weakly.

"Great Scott! Let me see that photograph again of your brother." Doc demanded.

Examining the picture, Doc observed, "Just as I thought, this proves my theory, look at your brother."

Sure enough, Dave`s head was disappearing.

"His head`s gone! It`s like it`s been erased."

Coming to conclusion, Doc finally put the pieces together.

"Erased from existence."

"What?"

"Now, tell me. What exactly have you done today? And I mean, in this time period, 1955. And give me every piece of detail." Doc demanded.

"Um, I decided to try and call you, but you wouldn`t answer. So I happened, to bump into my dad, who was still a wimp and being bossed around by Biff and all that, so right after he left, I followed him, to only find out that he was a peeping tom. Can you believe that? Who knew a wimp like him..." Marty muttered, getting out of the subject.

"Marty." Doc warned.

"Oh right! Uh, and I think that`s where I changed everything. I stopped my dad from being hit by my grandpa`s car, and that`s how my parents were supposed to meet. So I ended up at my mom`s house, seeing everyone so young, then I came to you."

Doc nodded. "I see. It seems you have inadvertently altered the future, causing your brother, sister ,and you to not be born! What we got to do, is to get your father and mother together, somehow.."

After a brief moment of silence, Doc concluded, "Show me where your father and mother are. That is, if you know where they are, and I assure you, Future Boy, that they will get together." Doc tried, with a hopeful smile.

Marty had to fake a smile at that.
