DISCLAIMER: I DON'T OWN ANYTHING BACK TO THE FUTURE
Katelyn is Marty Mcfly's 14 year old younger sister. They are very close and do pretty much everything together. Earlier today they received a call from Doc telling them to meet him in the parking lot of Twin Pines Mall at 1:15.
"Wh...wha?" she said blearily. "Come on Katelyn, it's almost 1:15" Marty shook her arm again. She looked up at him, half asleep. "5 more minutes mommy" she said and buried her head into her pillow. Marty rolled his eyes, smirked, and pulled the covers off of her. Katelyn sat straight up, "hey!" she yelled. "Come on we're going to be late", he said pulling her out of the bed.
They skateboarded into the Parking lot at 1:17. Doc's big white van was there but there was no sign of him, just Einstein sitting outside. "Hey boy where's Doc?" Marty asked petting him. All of a sudden, the back door of the truck lowered down and out came Doc driving a... DeLorean? "Marty! Katelyn! You made it!" Doc said climbing out of the car. "Welcome to my latest experiment this is the big one, the one I've been waiting for all my life. Alright roll tape!" Marty pulled out the video camera and started recording. "Good evening I'm Doctor Emmet Brown. I'm standing in the parking lot of Twin Pines Mall. It's Saturday morning October 26, 1985, 1:18 am. This is temporal experiment number one.
Katelyn watched as Doc led Einstein to the car and buckled his seat belt. He closed the door and then took out a remote. "You've got that thing hooked up to the car?" Marty asked. Doc ignored him and drove the car down the parking lot and turned it around facing them. Doc smirked," If my calculations are correct, when this thing hits 88 miles per hour you're going to see some serious s**t" Katelyn smiled and stood next to Marty gripping his arm nervously. You never could tell when one of Doc's experiments would go haywire. Doc revved up the car and started driving it straight towards them. Marty tried to walk out of the way, pulling Katelyn with him, but Doc pulled him back. "Watch this", he said. The car got closer and closer and when it was only a couple of feet from them, it disappeared, leaving a trail of fiery tire tracks behind. The license plate from the DeLorean had fallen off, the only thing left of the car.
Katelyn gawked at the sight and Marty stood looking in disbelief at the license plate. Doc was busy excitedly babbling in the background. "Jesus Christ Doc! You disintegrated Einstein!" Marty shouted. "Calm down Marty I didn't disintegrate anything" Doc said," the molecular structure of Einstein and the car are completely intact!" "Then where the hell are they?" Katelyn shouted. Doc looked back at her, "The appropriate question is when the hell are they! You see Einstein has just become the world's first time traveler. I sent him one minute into the future to be exact. And at precisely 1:21 and zero seconds we will catch up with Einstein and the time machine!" Marty and Katelyn looked at Doc in disbelief. "So your telling me you built a TIME MACHINE... out of a DeLorean?" Marty said out of breath.
"Watch out", Doc yelled and pushed Katelyn and Marty out of the way. The DeLorean appeared in the exact spot they were standing before. Doc opened the door and out jumped Einstein. "Well guys here I go to the future!" Doc said throwing his suitcase into the car. "Hey Doc", Marty said, "Look us up when you get there." Doc smiled, "I will….Oh I almost forgot the extra plutonium to power the car!" he said getting out of the car. "Hey by the way Doc where did you get that stuff?" Marty asked. "A bunch of Libyans asked me to make bombs for them. I stole the plutonium and gave them bombs made out of cheap pinball parts", Doc laughed.
Suddenly, Einstein started barking. "What is it boy?" Doc asked, following the direction Einstein was looking. "Oh my God they found me I don't know how they did but they found me! Run for it kids!" "Who?" Katelyn and Marty said simultaneously. "Who do you think? The Libyans!" Doc said getting out a gun. The Libyans were driving quickly while shooting at Doc. "Holy s**t! " Marty yelled pulling Katelyn down against the DeLorean. Doc ran to the back of his truck. "Doc wait!" Marty yelled but it was too late the Libyans had him cornered. Doc threw up his gun in defeat but they Libyans shot him anyway. Marty stood up "no! You idiots!" The Libyan turned to Marty. Katelyn stood up, grabbed Marty, and pulled him in front of Doc's truck.
"We have to get out of here!" Katelyn whispered. "Yeah I know!" Marty said pulling her to the other side of Docs van. The Libyans pulled in front of them and Marty stepped in front of Katelyn, eyes closed preparing to be shot. He was a little confused when nothing happened.
Katelyn peered over his shoulder and saw that the gun wasn't working. She quickly took Marty by the hand, and ran with him to the DeLorean before the gun started working again.
They both got inside and Marty started driving with the Libyans behind them in hot pursuit. "Alright let's see if these morons can reach 90" Marty said. Katelyn held tightly to her seat and looked at the side mirror. "MARTY!" she yelled. Marty looked out the window "crap!" The Libyan shooter had taken out a missile and was aiming it at the car but he never got to shoot.
The speedometer of the DeLorean read 88 mph and suddenly Marty was struggling to gain control of the car in a field. He ran into a scarecrow which landed on the windshield. Marty and Katelyn both screamed. The scarecrow flew off and they saw that they were headed straight for a barn. They screamed again before they crashed into it and silenced on impact. Marty groaned, "Are you okay Katelyn?" Katelyn coughed,"Yeah I think so" They both climbed out of the car. The barn door was open and there was a man with a gun standing there with children hiding behind him.
"Pa what are they?" a girl asked. "They're aliens!" the boy shouted, "and they've already mutated into human form! Shoot them!" The man started shooting at them.
Marty dove back inside the car while Katelyn jumped behind a hay bale to dodge a bullet that just whizzed past her ear. Marty opened the passenger door. "Get in!" he shouted. Katelyn peered out from her hiding spot, ran into the DeLorean and closed the door.
Marty stepped on the gas and burst through the wall of the barn he kept driving until the car died in front of a sign that read Lyon Estates. "Where's our house?" Katelyn asked. "It hasn't been built yet", he replied, sighing. "We don't want anyone to see this", he said getting out to push the car behind the sign. "We need to find 1955 Doc so he can help us find a way to get back home. And we have to make it to Hill Valley, so we better start walking."
