1.05: Time for a Chase

Hill Valley, California

Monday, November 7, 1955

8:00 A.M.

After spending all day Sunday buying some '50s clothes so Y/N and Jenna could blend in better, the teens walked up to school in their new outfits.

Y/N sported a brown and red jacket with a white buttoned shirt with short sleeves. On his legs were brown pants and Converse sneakers. Jenna, meanwhile, wore an orange shirt with long sleeves with a plaid dress, thigh-length white socks, and black shoes. While her hair was curled so short it looked like some type of bob cut, Y/N had his hair gelled to the side like the guys from "Grease."

Doc, meanwhile, wore a white suit jacket with a ridiculous shirt, green pants, and a fedora on his head. His cut had transformed into a scab, so he no longer wore a bandage over his eyebrow. He bought the alibi that he was their uncle and had enrolled them into the school to help get Y/N's parents together, even if it was only for a week.

"Whoa!" Y/N said in surprise as he looked at the school. "They really cleaned this place up. Looks brand-new."

"Sure, the school looks good," Jenna groaned, not happy about wearing a dress, "but women couldn't get comfortable clothes in the '50s?"

"Remember," Doc said as he guided the kids up to the school's front doors, "according to my theory, you both interfered with Y/N's parents' first meeting. If they don't meet, they won't fall in love, get married and have kids. That's why your older brother is disappearing from that photograph. Your sister will follow, and unless you repair the damage, you both will be next."

"Wait, why will I be erased?" Jenna asked. "I'm not related to Y/N in any way."

"It's simple," Doc answered. "If Y/N's parents never meet and he's never born, you'll never become friends with him in 1980 like you claim. Therefore, you won't come to assist me because you followed Y/N to me, and then you will never enter the DeLorean and travel back here to 1955. Therefore, you will still exist, but this version of you will be erased from the timeline."

"Sounds pretty heavy," Y/N said after Doc's long explanation.

"Weight has nothing to do with it," Doc argued.

The trio then stood in the crowded hallways of Hill Valley High School, trying to look for Y/N's parents.

"Which one's your pop?" Doc asked as the bell began to ring.

"Him," Y/N answered as he pointed at his future father. George L/N tried writing something in a small notebook as he walked, but kept getting kicked in the rear by bullies herding behind him since a note was taped to his back reading, "Kick me."

"Okay," George said. "Okay, you guys. Ha, ha, ha, ha. Very funny. You guys are being real mature. Okay, real mature, guys."

"Maybe you were adopted," Doc said to Y/N as they continued to watch Geroge get bullied to the point his books were dropped.

"I wish I was adopted," Y/N groaned.

"Okay, pick up my books," George said as Mr. Strickland, who was 30 years younger and still bald, walked up to him. The herd of predators then retreated from their prey.

"L/N," Strickland said as he began to give Y/N's father a lecture.

"That's Strickland," Jenna said. "Jeez, did that guy ever have hair?"

"Shape up, man," Strickland said as he took the note off of George's back. "You're a slacker. Do you wanna be a slacker for the rest of your life?"

"No," George answered as his principal walked away.
