After thirty minutes, the pair finally arrived at one of the numerous neighborhoods in Hill Valley. They had been trailing George since they left the town square.

They came to a sudden halt as they spotted a massive oak tree by the roadside. Breathing heavily, they exclaimed, "Where the hell is he?" Their dad was nowhere in sight.

Ally suddenly spotted George's bike resting on the pavement next to the tree. Her attention then shifted upwards, where she caught sight of their dad perched in the tree, using a pair of binoculars to observe something happening across the street.

"You're not looking high enough," Ally told Marty, prompting him to glance up at the tree. They then shifted their gaze towards the window where George was peeping on a girl who had taken her top off.

Ally let out an exasperated sigh and rubbed her temples. "Jesus Christ, Dad," she muttered. "He's a peeping tom," Marty grimaced, repulsed by George's voyeuristic behavior.

George hadn't even taken a proper look when he suddenly lost his balance and desperately clung onto the sturdy branch. Unfortunately, he couldn't hold on any longer and tumbled down from the tree, landing right on the street just as a car was approaching towards him.

"Dad!" Marty shouted as he sprinted into the street. Without a second thought, he acted on his gut feeling to rescue George from the oncoming car.

In a split second, he managed to shove George to safety just moments before the vehicle collided with him, causing him to fall backwards and hit the back of his head on the pavement. The car screeched to a stop after it hit him.

As soon as he hit the ground, Ally rushed towards her brother and immediately dropped down next to him. "Marty! Oh no!" she exclaimed, filled with panic, worried that he might have suffered a concussion due to the impact on his head.

In a brief moment, he glanced upwards before losing consciousness. "Oh shit... Marty, come on! Wake up, wake up!" Ally yelled, vigorously shaking him. However, he remained unconscious.

Then, the owner of the car got out just as George was finally standing up from being pushed. The man first observed Marty on the road before he looked over at George. "Wait, who are you?" he asked.

George wasted no time, snatching his bike and swiftly pedaling away from the scene. The man then turned his attention to the distressed girl beside Marty. "Who the hell are you?" he asked her.

Ally, in a state of panic after witnessing her brother being struck by a car, frantically declared, "I'm his sister! You were the one who hit him!" The man observed Ally's intense determination to help her brother.

"Okay, let me get my wife and we can get him in the house," the man said, before looking up at his house next to them, "Stella! Another one of these damn kids jumped in front of my car! Come out here and help me take him in the house! His sister is out here!"

Stella, the man's wife, emerges from the house and exclaims, "Oh, my lord!" as she approaches her husband. The first thing that catches her eye is Ally's attempt to wake her brother.

Ally helped support Marty by placing one of his arms over her shoulder, while the man did the same with Marty's other arm over his shoulders.

As Marty was escorted to the house, two additional children emerged to investigate the commotion. "Hey, what's happening?" inquired a boy sporting a raccoon hat atop his head.

"He was hit by your father's car. We gotta get him inside," Stella told her son as they brought Marty inside the house. As they carried Marty into the house, a young girl glanced up at Ally.

"Are you his girlfriend?" the little girl asked the 17-year-old girl. "I'm his sister. Twin sister actually," Ally clarified.

Stella's voice echoed through the house as she called out, "Hey Lorraine, could you come down here real quick?" Ally's eyes widened in surprise upon hearing that familiar name. It was the same name as her and Marty's mother.

Shortly after, a young girl about Marty and Ally's age rushes down the staircase. Ally immediately recognizes her as their mother when she was a teenager, just as she had anticipated.

Lorraine inquired about her mother, "What's wrong, mother?" as she descended the stairs. Stella informed her, "This young man was hit by your father's car. Help me get him upstairs."

Lorraine quickly looked over at Ally before questioning, "Are you dating him?" Ally hesitated before responding, "No, I'm actually his twin sister," feeling a bit uncomfortable with her mother's inquiry.

Marty was assisted up the stairs by the others before they headed to Lorraine's bedroom. Ally hesitated to leave Marty, concerned about his well-being.

"Go wait downstairs, hon. We'll take care of him," Stella reassured Ally, who watched as Lorraine tended to Marty's injuries, taking off his body warmer and his overshirt.

Reluctantly, Ally obeyed and made her way downstairs, unsure of when Marty would regain consciousness. She settled on the couch, waiting anxiously.

(7:30 PM)

Marty jolted awake in a bed that evening, his head throbbing from the impact on the concrete slab in the street. He felt disoriented from the blow to his head.

As he lay in bed, he caught a glimpse of what appeared to be his mother standing near the bedroom window. With the covers pulled over him, he mumbled, "M-Mom? Mom, is that you?" His eyes slowly opened, trying to confirm the figure before him.

Marty stirred awake to find a figure approaching him. "There, there now. You've been out for nearly nine hours," a voice he recognized as his mother reassured him, gently wiping his forehead with a cool cloth. Feeling comforted, he rolled onto his back and drifted back to sleep.

"You won't believe it, but in my dream, Ally and I traveled back in time. It was terrible," he said, clutching the blankets tightly. Lorraine tried to reassure him, saying, "You're back in the good old 1955 now."

Marty's eyes widened in disbelief when Lorraine mentioned the year 1955. "1955!?" he gasped. Suddenly, the bedside table lamp turned on, illuminating the entire room in a warm yellow glow.

In an instant, he whipped his head around to see Lorraine, only to find his mother as a teenager, causing him to jolt upright. Lorraine then calmly took a seat by the window, fixing her gaze on him.

He struggled to find the right words, "You're my mo- You're my mo-," completely taken aback. "My name is Lorraine. Lorraine Baines," she introduced herself, removing her jacket. "Yeah! But you're, um, you're so, uh, so... thin!" he blurted out, unsure of how to express himself.

"Take it easy, Calvin, you got a big bruise on your head," Lorraine said. Marty felt scared and unsure as he touched his head, trying to catch his breath. He couldn't understand why Lorraine was calling him Calvin when that wasn't his name.

As he tried to stand up, he looked down and realized his jeans were no longer on his legs. "Agh! Where are my pants?!" he cried out, covering his legs with a blanket. He also saw that his overshirt, denim jacket, and body warmer were missing, leaving only his red shirt on.

He blushed with embarrassment. Lorraine glanced at a chest placed at the foot of the bed. "It's over there, on my hope chest," she mentioned, pointing towards it.

Lorraine's gaze shifted from Marty's covered legs to his blue eyes. "You know, I've never seen purple underwear before, Calvin," she remarked. Perplexed, Marty shook his head and questioned, "Why do you keep calling me Calvin?"

"Hey, isn't your name Calvin Klein? It's all over your underwear," she teased, trying to uncover Marty's legs, but he moved away quickly to avoid it. Startled, he glanced around and realized Ally was nowhere to be found in the room.

Lorraine noticed and asked, "Who are you looking for?" He responded, "My sister. Where is she?" Lorraine then informed him, "You mean Alexis? She's downstairs with my mother."

Marty was happy that Ally was downstairs, but things got awkward when Lorraine sat too close to him. He tried to ignore her words, feeling uneasy. He silently hoped Ally would rescue him from the uncomfortable situation of his own mother hitting on him.

Lorraine noticed the huge bruise on Marty's head and reached out to touch it, saying, "Wow, that's a really big bruise," However, Marty quickly moved away and accidentally fell off the bed, making a loud noise when he hit the floor.

Ally was napping on the couch downstairs when she suddenly woke up to a loud noise. "Marty?" she called out as she sat up, ready to go upstairs. However, Stella intervened and prevented her from going up the stairs.

"Hey Lorraine, are you upstairs?" Stella shouted for Lorraine. Ally quickly got up from the couch and stood near the stairs while Stella went up. Ally was really concerned about her brother's well-being after that terrible hit. She had been worrying so much for the past nine hours.

Ally couldn't contain her excitement as she climbed the stairs, eager to see Marty. Her heart skipped a beat when Lorraine and Marty emerged from Lorraine's bedroom. "I'm so relieved you're okay, Marty," Ally exclaimed, feeling a weight lift off her shoulders.

Ally saw a strange expression on his face as he entered the room - She also saw Lorraine giving him a flirty glance. "Uh, should I even ask what's going on?" She inquired, arching an eyebrow.

Marty shook his head, "No, you really don't want to know." Following Lorraine and their grandmother down the stairs, their grandmother inquired, "How long have you been in port, Marty? Did your sister come with you?"

Marty looked puzzled, "What?" he asked, not quite grasping what she was saying. Stella walked over to him, pointing at the life preserver, "You must be a sailor with that life preserver on," she teased, eyeing the brand new TV he was fixing up.

Stella stood with her hands on her hips, "Look, here's the young man you hit with your car. Luckily, he's okay. But you really scared his sister to death," she said. Sam glanced over from the TV, a screwdriver in his mouth, and removed it before responding.

"Why were you out in the street like that?" He snapped at Marty. Stella just shook her head and headed towards the dining area. "Ignore him, he's just being grumpy. Sam, stop playing with that and come eat," she called out.

Marty and Ally walked behind their grandmother into the kitchen, where three out of the four youngest kids were gathered around the table. Lorraine was next to one of the chairs. "Lorraine, you've already been introduced. These are Milton, Robert, and Sally. And in the playpen over there is little baby Joey."

Marty and Ally glanced back to locate their soon-to-be Uncle Joey. He appeared to be a toddler, just a few years old. They both crouched down in front of him as he amused himself with some rings on the wooden playpen bars. "Well, well, well, look who we have here - Uncle Joey," Ally remarked with a grin.

Marty tapped the wooden bars and warned, "You better start getting used to these bars, kid." Stella noticed the twins watching Joey in his playpen, so she approached them and mentioned, "Joey really enjoys playing in his playpen. He gets upset when we take him out, so we just let him stay there most of the time."

Marty and Ally made their way back to the dining table, where Lorraine kindly gestured for Marty to take a seat. "Sit here, Marty," she said, as Ally settled down on his right, noticing his unease around their younger mother.

"Sam, stop meddling around with that thing and come in here and eat your dinner," Stella said to her husband before walking over to her seat at the table. "Well, Marty, Ally, I hope you two like meatloaf," she said as she sat down.

Sam gleefully pushed the TV over to the dining table, chuckling, "Check this out! We can watch Jackie Gleeson while we have dinner!" He hurried back to his seat with excitement. Throughout this, Lorraine was giving Marty flirty looks, something Ally picked up on immediately.

'The hell? Is mom actually flirting with Marty? Oh, my Goooooddd…' Ally thought, feeling just how awkward this was. The awkwardness of the situation was palpable. Marty's uncomfortable expression said it all as they both turned their attention to the TV screen.

"It's our first television set. Dad just picked it up today. Do you and Jackie have one too?" Lorraine asked Marty. Ally glanced at Lorraine, momentarily forgetting that she was using an alias to conceal her true identity.

Marty stammered, "Uh, yeah, we do. We've got two," as he nervously fidgeted with his hands on the table. Ally sighed and wanted to leave the uncomfortable moment, but she couldn't just abandon Marty.

Their Uncle Milton, with a raccoon hat on his head, smiled at them and exclaimed, "You must be loaded!" Stella chuckled and reassured them, "Oh, he's just joking. No one has two TVs." The twins glanced at the television and noticed The Honeymooners playing on the screen.

The TV was showing the same episode from 1985, which caught Marty's attention. "Hey, we've seen this one! This is a classic," he exclaimed excitedly. Ally, feeling exasperated, thought, "Please don't drag me into this, Marty."

"Ralph is dressed like an alien here!" Marty kept talking. Did he forget they were in the fifties? Milton looked confused by Marty's words. "What do you mean you two saw this before? It's new," he said, looking puzzled.

"Well, we saw it on a… rerun," Marty said, slowly realizing what he was doing. "What's a rerun?" Milton asked. Ally wanted to give her brother a good kick for saying that but she restrained herself from doing so. "You'll find out," was all she said.

Stella leaned her head on her hand to get a closer look at the twins. "Marty, you and Ally seem so familiar. Have I met your mother before?" she inquired. The twins exchanged uncertain glances at Lorraine, unsure of how to respond.

They couldn't say that their mom was actually the oldest daughter. "Um, yeah, she's a lot closer than you think," Ally whispered. "I should probably call her so she doesn't get concerned," Stella suggested.

"No way! Nobody's here," Marty exclaimed. "At least, not right now," Ally added, trying to avoid raising their future grandmother's suspicions.

Ally suddenly recalled that Marty had ripped a page from the phone book. She patted Marty on the shoulder and cleared her throat, reminding him that they still needed to find Doc. Marty then took out the page and opened it. "Hey, um, do you know where 1640 Riverside Drive is?" he asked.

"It's over on the other side of town, past Maple Drive," Sam replied, his eyes fixed on the TV as he ate. "Oh, past Maple? Isn't that near John F. Kennedy Drive?" Marty inquired. Sam paused mid-bite, looking over at Marty, clearly not recognizing the name at all.

"Who the hell's John F. Kennedy?" he inquired. Lorraine then chimed in, "Hey mom, since Marty and Ally's folks are away, shouldn't they stay here tonight? I mean, Dad did run over Marty with the car."

Marty and Ally's breath caught in their throats as they squirmed in their chairs. Ally's mind raced with worry, hoping desperately that they wouldn't have to remain in that place for much longer.

"Oh, it's fine. We really should leave," Marty said nervously, gesturing with both hands. "I believe you and your brother should stay the night. We're responsible for you," Stella agreed with Lorraine.

Lorraine offered, "Marty can stay in my room," as she squeezed Marty's leg suggestively. Ally noticed and quickly intervened, pulling Marty out of his seat. "Wow, would you look at the time! We have to go see our uncle actually," Ally fabricated an excuse, not wanting their mom to get any ideas about Marty.

"Oh, man! I totally spaced on that! We were supposed to be there hours ago, so we'll catch up with you guys another time. Probably much later," Marty mentioned as he and Ally headed to the front door and left the house, hoping to avoid running into them again.

Stella glanced over and inquired, "Do you think those two are odd?" Sam replied, "Definitely. It must be how they were raised. Their parents are likely just as clueless. Lorraine, if you end up with kids like that, I might have to disown you." Little did Sam know, those were his future grandkids.
