11:30 AM PST
A few seconds after Marty arrived in the year 2016, the flux capacitor and the time display panels stopped working. After he landed the DeLorean, he tried to turn the time circuits back on, but they failed. Marty suddenly felt hopeless.
"This is nuts," Marty muttered to himself. He made a few more attempts to turn the time circuits on. After it was evident the time circuits had failed, Marty gave a deep sigh of resignation. He immediately knew what he needed to do. He had to look for Doc from this time period. He wondered if many might mistake him for his son.
Marty sighed to himself, as he began to drive the DeLorean over to Doc's home. He hoped that Doc lived in the same house in this year. He did his hardest to remain as calm as he possibly could. After all, he knew getting himself worked up would never accomplish anything productive. He hoped Doc would know what to do.
oooooooooo
"Marty should be getting back here soon," Harmony said, as she was a little antsy. "I really want to go to the dance this afternoon. I hope nothing bad happened to him."
"Just try to be patient, honey," Doc suggested to his granddaughter. "You know that he needs to have some time to drive the DeLorean from the park. Also, there is the possibility that the skyways could become jammed. So please don't fret, dear."
"I suppose you're right, Grandpa," Harmony said, sighing. "I'm just so anxious to get to that dance, I guess. You know, I can hardly wait for everybody to see me wearing my new dress. I sure hope Marty and I win some sort of award."
Just then, the doorbell rang. Harmony and Doc stood up, as they went to answer the door. Harmony hoped that Marty Jr had returned from 1986.
"You're back, Marty!" explained Harmony. "What made you decide to change your clothes, though? You didn't buy new clothes back in 1986, did you?"
"Actually, I'm not who you think I am," Marty said, quietly. "I'm not Marty Jr. I'm his father from the year 1986. I came here, because it appears that the time circuits on the DeLorean are fried, so I can't get back home. So you have to help me, Doc."
"Great Scott!" gasped Doc. "We have to get you back home, or else we'll have a big paradox. You see, if we don't get you back home, Marty Jr will become erased from existence!" Realizing something else, Doc gasped, "Marty Jr! I wonder if he may still be back in 1986! I sent him back to that year to run some errands for me."
"Whoa, this is heavy," Marty breathed. "If I'm stuck here in 2016, then I wonder if my son is stuck back in 1986. I wonder if this may have something to do with what caused the time circuits to become fried. Things don't look very good to me."
"Now we'll never be able to make it to the dance," moaned Harmony. "Why did this have to happen to us? I was looking so forward to this dance for a long time."
"Yeah, so was I," replied Marty. "You see, Jennifer and I were also planning to attend the dance back in 1986. I guess we're all in the same boat. Such is life, I guess."
"I have a suggestion," exclaimed Doc. "Marty, how about you go bring Harmony to the dance? You look just like your son, so you can just pose as him. Meanwhile, I'll go check out the DeLorean, and see what may have caused the time circuits to get fried. Harmony, I will be certain to give you a call on your cellphone, when I figure out what happened. In the meantime, please try not to fret so much."
"I just thought of something," offered Marty. "Do you remember what you did back in 1986, when Marty Jr was stuck? It would be in your past, after all."
"Well, uh..." After Doc thought long and hard, he replied, "I'm afraid that I'm drawing a blank. I think I might currently have a condition of temporal amnesia."
"What is temporal amnesia?" Marty asked, confused. "How could something like that have happened? I have a really bad feeling about this, Doc."
"It's a condition of where you momentarily lose your memory of past events," Doc explained. "I guess it's some sort of self-correcting mechanism - where, if I was to retain my memories of that event, it might create a paradox."
"I don't get it, Doc," Marty said, confused. "How could remembering that event create a paradox? You know, if anything, I think remembering that event would make things a lot easier for you. After all, you would remember what you did with my son."
"The thing is," Doc explained, "you and your son have officially switched places with each other - so the events of your son back in the year 1986 is concurrent with the events that is taking place right now. I have precisely 24 hours to send you back to the year where you belong. Do you remember the time of when you came here?"
"It was 11:30 AM," Marty explained, "and then everything burnt out. I tried several times to turn the time circuits back on, but I'm afraid that they're shot."
"Well, why don't the two of you head over to the dance?" Doc suggested. "Just try your best to enjoy yourselves, and I'll start working on the DeLorean."
"Sounds great, Grandpa," Harmony replied. "Well, Marty, let's grab our hoverboards and go. Oh, yeah, this blue hoverboard here belongs to your son."
"I guess I'll see you later, Doc," Marty called out, as he followed Harmony to the dance that was taking place at Hill Valley Park. He wondered what kind of music might be played there. He hoped the music of the future was good.
oooooooooo
"Whew, this sounds like a great song," Marty exclaimed, as he and Harmony arrived at the dance. "What is this song called, and who performs it?"
"It's called Come Out And Play," Harmony explained, "and it's by The Offspring. One thing I really like about this dance is that we won't be hearing all this rap crap."
"You two have made it," exclaimed Marlene. "I love your dress, Harmony. Meet my boyfriend, Mike Hartford. This is our first date together."
"Pleased to meet you, Mike," Marty said, as he shook Mike's hand. "The two of you look so great together. Why don't we head on over to the refreshments stand?"
"We were just there a few minutes ago," replied Mike. "I'm so amazed by how much you and your sister resemble each other. So you're one year younger than her?"
"Yeah, I'm eighteen years old," Marty replied. "So do you go to college?"
"Yeap," replied Mike. "I just moved here to Hill Valley a few weeks ago. So, this fall, I will be attending Hill Valley University. So, Marlene tells me that you play in a rock band? I am a huge fan of your father's music, you know. I bet you take after him."
Marty was stunned for a few minutes, then he realized that Mike was talking about him! Marty nearly fainted, but Harmony caught him.
"Are you okay?" Mike asked, concerned. "I didn't say anything wrong, did I?"
"No, you didn't," Harmony was quick to say. "I think the heat is just getting to him. I will talk with you guys a little later. I have to get him to some shade, and find a cold drink for him. The two of you just go have some fun."
"Well, you don't want to miss the dance," Mike insisted. "I hope you're okay."
"Thanks, Mike," Harmony replied, as she and Marty walked off.
