(6:30 PM, At Doc's House)

The siblings had made it to Doc's house, which was bigger than they thought. "Is this the place?" Ally asked, not so sure. Marty saw a small stone wall with the numbers to the address. "Yeah, this is it," Marty said, "C'mon."

Marty and Ally jogged up the driveway and made it up the front door. Marty knocked on the door and they waited for a few seconds. The door opens for a second, and an eye peeked out. The door shuts again.

"Huh? Was that-?" Ally says, turning around at the sound of the door opening and closing. Marty was about to knock again but the door opened again, revealing a much younger doc with a large contraption on his head.

"Doc?" Marty said. "Don't say a word," Doc said, grabbing the both of them and pulled them both inside, slamming the door shut. "I don't want to know your names or anything about either one of you," Doc said quickly, unhooking a device from his little dog.

"Doc, wait! You gotta listen to us!" Marty said, holding his hand up his hands in hopes of calming Doc down. Doc then sticks a suction cup on Marty's forehead. Marty and Ally were both confused, not understanding what Doc was doing and why he wasn't listening to them.

"Doc, what're you-" Ally started but Doc cut her off. "I'm gonna read your thoughts. You two come from a great distance," Doc guessed. Ally and Marty both nodded.

"Yeah, that's right! We did!" Ally exclaimed. Doc wagged his finger at her. "Don't tell me, you want me to buy a subscriptoion from the Saturday Evening Post?" Doc guessed again. "No, we-" Marty started.

"Not a word. Not a word now! You two… want me to donate to the Navy Core?" Doc continued. They had enough of this and needed to tell Doc of their situation.

"Doc," Marty sighed, pulling the suction cup off of his head, "We'll be blunt with you. We are from the future. My sister and I came in a time machine that you invented. Now we need your help getting to the year 1985."

The whole time, Doc was paying attention to what Marty was saying. "My god, do you two know what this means?" he said, putting a hand on each on their shoulders. For a moment, they though he would listen to them, but they were wrong. Not to mention, his tone didn't help ata ll.

"It means that this damn thing doesn't work at all!" Doc said, turning away after taking off his mind-reader helmet before going to another room. Ally and Marty quickly followed him.

"Doc, you gotta listen to us. You're the only one who know how your time machine works," Ally said, leaning on a table with a large lamp on it, which was turned on. Doc was confused, he put a hand to his head, eyes widened in bewilderment.

"Time machine? I haven't invented any time machine," Doc whispered. Marty then pulls out his wallet from his back pocket. "Alright, look at this. My driver's license expires 1987. Look at my birthday for crying out loud, I haven't born yet!" Marty said, pointing at the date.

"Yeah, and I was born in 1970!" Ally added. She then pulls out a picture of her, Marty, David, and Linda standing in front of a fountain. Marty leaned back against the fountain, using his hand to holding himself up. Ally had her arms crossed over her chest with a grin on her face.

"Take a look at this picture, our brother, sister, Marty, and me. Look at our sister's shirt, class of '84." Ally said, pointing to each person in the picture. Doc took the picture from Ally's hand and examined it, squinting his eyes to get a better look.

"Pretty mediocre photography fakery, they cut off your brother's hair," Doc said, tossing the picture on the desk. Marty picks it up with a slap on the table. "Doc, we're telling you the truth! You've gotta believe us!" Marty said.

Doc turns towards the teens. "Then, tell me, future boy and future girl, who's the president of the United States in 1985?" Doc asked. "Ronald Regan," the siblings said in sync without an issue.

"Ronald Regan?! The actor?!" Doc said flabbergasted, picking up some rolled up papers from the table. "Then who's Vice President? Jerry Lewis?!" Doc exclaimed, turning around and running out of the house.

The siblings chased after him as Doc ran to his garage. "I suppose Jane Wyman is the first lady!" Doc yelled as he was running to his garage with the rolled up papers in his arms. "Whoa, wait, Doc!" Marty shouted.

Doc quickly opens the garage door and runs inside. "I've had enough practical jokes for one evening! Good night future boy and future girl!" he shouted before slamming the door shut. "No Doc! The bruise on your head! We know how that happened!" Marty shouted, smacking the door with the palm of his hand.

"Yeah, you told us the story! You slipped on your toilet and hit your head on your sink while hanging a clock! That's when you thought of the idea of the flux capacitor. Is which is what makes time travel possible," Ally said, turning around for a moment.

It was quiet for a moment, making both siblings think Doc didn't convince him that they were from the future. But when he opened the door and he stepped out with wide eyes, they knew they had him convinced.
