Afterward, the trio made their way to the local library to do some further research on Buford Tannen. After entering the library, Marty grabs a book from a shelf and brought it over to a table, where Ally was waiting.
Marty opened it and placed it on the table. It was on the page showing Buford Tannen. He starts to read aloud, 'Buford Tannen was a notorious gunman whose short temper and a tendency to drool earned him the nickname 'Mad Dog'. He was quick on the trigger and bragged that he killed 12 men, including Indians and Chinamen,"
"Geez, thank god we're not related to those guys," Ally responded. Doc gulped and asked, "Does it mention me? Am I one of the twelve?"
Marty gulped and continued reading, "'However, this claim cannot be substantiated since precise records were not kept after Tannen shot a newspaper editor after printing an unfavorable story about him in 1884.' That's why we can't find anything," Marty sighed.
Doc had brought over another history book, opens it to an old snapshot of five or six people. One of which looked exactly like Marty. "Look at this. McFly Family. Your relatives?" Doc asked them.
The siblings were surprised that their great-great-grandfather looks just like Marty. And their great-great-grandmother looks like Ally. "Wow, I see the resemblance," Ally said, putting a finger on their relatives. "Wow, good-looking guy," Marty commented.
"McFly's but no Browns!" Doc groaned. "Well, Doc, did you have any relatives here?" Ally asked. "No, the Browns came to America in 1908, and then they were the Von Brauns," Doc answered, shaking his head.
Ally looked through the album and found a picture of Doc standing in front of the clock for the clock tower. "Guys, take a look at this," she said, pointing at the picture. Marty and Doc look at the picture.
"Great Scott! It's me! Then this is true; all of it! It's me who goes back there... and gets shot," Doc exclaimed. Marty and Ally look at one another, thinking the same thing. They couldn't let Doc go like that.
Marty confidently says, "It's not going to happen, Doc. Once you put new tires on the Delorean, Ally and I are gonna go back to 1885 and we're going to bring you home," "There isn't anything you can say that'll make us change our minds," Ally added.
Doc smiled at the two of them. He saw how determined they were to bring his other self back. "Alright, but be careful," Doc responded. "Aren't we always, Doc? Well, except for the time we got locked out of our house while it was raining cats and dogs," Ally sheepishly said.
Marty blushed in embarrassment, "That wasn't our fault! Dad had left his keys in the house!" "Hey, cut me some slack, Marty! It was after midnight!" Ally exclaimed, smacking him on the arm. Doc defused the argument and responded, "Alright, break it up, you two! This is not the time for a sibling quarrel,"
"Ah, fine, but I'll get you next time," Ally joked, looking at her brother. Marty gave his little sister a noogie.
Early the next day, the Delorean was ready to go, only the tired needed to be inflated. They are at a drive-in just outside of town. Marty is still in the bathroom, getting dressed in a western outfit so he'd blend in. Doc was outside checking the tires to the Delorean
Ally was already dressed up. She wore a white long-sleeve shirt with a black vest and a red scarf, a beige skirt that went down to her ankles, black cowboy boots, a black, and a cowboy hat.
Doc looked at the fifteen-year-old and asked, "Where'd you get that outfit, Ally?" "Oh, it was in the Delorean's front. It's the perfect outfit for me. I'd be a real gunslinger," she said. Doc grin at her and called to Marty in the bathroom, "Do the clothes fit, Marty?"
"Yeah, but the boots are kinda tight. I don't know. Will this work?" "Have you and Ally ever seen a western?" Doc asked, "Yeah, but, uh..." Marty said, coming out of the drive-in bathroom.
Ally used all of her willpower to not laugh at what he was wearing. It was a pink cowboy outfit that looked like it was from the un-authentic western movies. "Clint Eastwood never wore anything like this," Marty said.
"You're right, brother of mine. He would be so insulted if he caught you dead in that," Ally said, trying not to laugh. "Oh, funny, funny. You look like Annie Oakley," Marty said. Ally became flustered and crossed her arms. "Do not!" she pouted.
Doc ignored their little quarrel and noticed the shoes they were wearing. "Marty, you can't be wearing those shoes in 1885. You two will be killed! You shouldn't even be wearing them in 1955," he said.
Marty had his boots in his hands and he says, "Don't worry, I'll put them on when we get there," Doc went down the list of items that they'd take with them. "Alright, I think we're about ready. I put gas in the tank, y'all's future clothes are packed, just in case fresh batteries for our walkie-talkies. Oh, and what about that floating device?"
"Hoverboard," Marty answered, putting the hoverboard in the DeLorean. "Oh man, it's gonna be a hell of a walk to Hill Valley," Ally said. "It's still the safest plan. After all, we can't risk sending you two back to a populated area, or to a spot that is geographically unknown. You don't want to crash into some trees that once existed in the past. This is all completely open country! So you'll have plenty of run-out space when you arrive! Remember where you're going there are no roads! There's a small cave over there which will be a perfect place to hide the time vehicle. Well, the new time circuits are warmed up!" Doc explained.
Doc sat down in the driver's seat of the Delorean and flicked the time circuits on. "I wrote the letter on September 1, 1885, so we'll send you two back to the day after that. September 2, 1885, that's a Wednesday. I get shot on Monday, the 7th, so you have 5 days to locate me. According to my letter, I became a blacksmith, so I'd probably have a shop somewhere. All you two have to do is drive the time vehicle directly towards that screen accelerating 88 miles mph," he said, pointing to the drive-in screen.
There were Indians on horseback painted onto the wall. Ally looked at the wall and said, "Hold on Doc. If we drive straight towards the screen, we're gonna crash into those Indians,"
"You're not thinking fourth dimensionally, Ally! You both will be transported to 1885, and those Indians won't even be there," Doc explained to her. Marty glanced at the painting and said doubtfully, "Right, Doc,"
Doc smiled at them and placed a hand on their shoulders. "Good luck, for your sakes. See you both in the future," he said. "You mean the past?" Marty corrected. "Exactly," Doc nodded.
Marty and Ally got inside the Delorean. Marty turned the car on and backed it up to the wall that was facing the Drive-In screen.
"Ready?!" Doc called from the concession stand. "Ready, Doc!" Ally replied. Marty shook his head and mumbled, "Hi ho silver,"
Doc fires his gun and Marty hits the gas. The Delorean speeds through the Drive-In, towards the mural in front of them. There were three sonic booms that they knew very well.
The siblings were transported through time right before they crashed into the Indian mural. Both hoped that those Indians would be gone as Doc had said. But when they teleported to 1885, they came face-to-face with a tribe of REAL Indians.
Marty hit the brake pedal, causing the car to slide on the roadless ground. "INDIANS!" the siblings scream simultaneously. Marty quickly turns the car around and drives away from the Indians, who were chasing them on horseback.
"Marty, look! The cave!" Ally shouted, seeing the cave out of the rearview mirror. Marty backed up into the cave just as the Indians leaped off of the cave, kicking dirt up as the horses galloped.
Once the tribe was gone, the siblings got out of the Delorean walked out of the cave, and walked over the ridge. But they hear a trumpet playing and a bunch of cowboys riding directly towards them. "Shit, the Calvary!" Marty yelled, pulling his sister down into the cave again.
Not a few minutes later, the siblings saw that the coast was clear. They sigh a breath of relief. Ally started to hear the sound of liquid coming from the Deloean. "Um, Marty, tell me I'm not the only one hearing that," she said, walking back to the car.
Marty knelt down and saw the source of the problem, "Damn, the fuel line is ripped," Ally threw her arms up and said, "Wonderful," He opened up the Delorean wing door and gets his boots and the photograph of the tombstone that Ally took, stuffing it in his back pocket.
Then, the siblings hear the sound of a bear growling. They look up and see a grizzly bear standing a few yards away from them. "Oh shit!" Ally gasped, backing up, almost losing her balance.
The bear stands on its hind legs and roared at them. "RUN!" Marty screamed, grabbing Ally's hand. The two sprint away from the bear as fast as they could. Marty threw his boots at the bear. Luckily, the bear didn't chase them anymore since it was more interested in Marty's discarded boots.
Before he could stop himself, Marty slid down a steep ravine. The fall caused him to let go of his sister's hand. Marty rolled down the hill and crashed into a wooden fence, instantly knocking himself out.
"Marty!" Ally shouted, sliding down the ravine to catch up with her brother. She saw a man slapping Marty on the cheeks. The man shouted in an Irish accent, "Maggie! Fetch some water! We got a hurt man here!" Ally knelt down next to her brother, hoping he'd be okay.
