9:30 AM PST
"Hey, Marty," Marlene called out. "You need to get up. Dr. Brown is on the telephone, and he really need to talk with you. He says that it's very important that I get you."
Marty was very stunned, as he woke up. He realized that he was in 2015, and he had spent the night sleeping in Marty Jr's bedroom. He wondered if Doc did manage to fix the time circuits. As nice as 2016 was, he was starting to miss life back in the 1980s.
"Yeah, Marlene," Marty said, sighing, "I'm getting up, now. Tell him that I'll be there in a few minutes. I want to get dressed first, and grab myself something to drink."
"All right, then," Marlene said, smiling. "I'll tell him that you'll be right over. Mom and Dad had a meeting to attend, so they're not going to be home for a few hours. I'll be leaving right away, too. I promised Lila that I'd meet her at the Courthouse Mall."
"All right, then," Marty replied, as he sat up in bed. "Have fun, Marlene. I will talk to you a little later. I really hope Griff doesn't give you any trouble today. I was really furious, when I saw him harassing you at the dance. That guy is such a jerk!"
"I laughed hard," Marlene replied, "when I heard all about how you made him and his gang crash into manure. I really wish I could've been there to see it. Maybe Griff will have finally learned to not mess with us. I hope the manure caused some damage to his bionic implants. That scuzzball really deserves it, you know."
"Well, let's hope so," Marty said, laughing. "Anyway, just tell Doc that I'll be there."
After Marlene left, Marty wondered about what kind of meeting his older self needed to attend. He decided it was probably best that he not find out. He might have found out too much, already. He decided to quickly throw on his clothes.
Marty stared at all the surrounding, as he made his way into the living room. A lot of the futuristic devices were really amazing to him. It seemed like most of the devices required only your voice to work. It was almost like your voice had magical powers.
"Hello, Doc," Marty called out, when he reached the living room. "Were you able to fix the time circuits yet? Hey, Doc, what if I don't make it back to 1986 on time?"
"Try not to worry, Marty," Doc replied. "I just have a few more things that I need to adjust, but I'm sure I will be ready to send you back to 1986 at around eleven."
"I guess we'll be safe until 11:30," Marty said, sighing. "Anyway, I realize that I still need to pick up some items for your younger self. I was actually able to make Griff crash into some manure, and I feel so triumphant. The Tannen tradition lives on!"
"That's wonderful, Marty," Doc said, admiringly. "Just make sure you come back here at around eleven. We will succeed! Remember, Marty, if you put your mind to it - you really can accomplish anything. We will definitely get the two of you switched back."
"Got it, Doc," Marty said, with a small smile. "I'd better get going, now - so that I can pick up a few items for your younger self. I will be by your place at around eleven. I hope I don't have much difficulty finding the items that your younger self needs."
"Good for you, Marty," Doc replied. He quickly smiled at Marty, before he hung up.
Marty wondered how his older self's memories would be affected, after he headed back to 1986. Time travel can be very complex, Marty thought, as he left the house. He stepped on the hoverboard, as he went downtown to buy a few items.
oooooooooo
Marty was feeling rather anxious, as he knock on the door to the Browns' house. It was already ten minutes after eleven, and he need to head back to 1986 soon.
"Oh, Harmony!" Marty gasped, as soon as Harmony opened the door. "What are you doing here? I mean, it's really nice to see you - but I really wasn't expecting you."
"Well, I thought I'd visit my grandparents for awhile," Harmony said, smiling. "I also wanted to make sure that I said good bye to you, before you left. You and your son really do have a lot in common. Kissing you really didn't feel the same, though."
"I guess we did have lots of fun yesterday," Marty replied. "So how is Doc doing with fixing the time circuits? I do have to make it back to the year 1986, before the ripple effect catches up. I'm not sure how this might affect you or Doc, though."
"Yeah, I guess we are pressed for time," commented Harmony. "In a strange sort of way, I really will miss you - even though your older self will still be here."
"Yeah, I understand what you mean," Marty said, softly. "I will sure miss you, too. It did feel a bit funny pretending to be your boyfriend, yesterday. I'm sure things were even worse for my son. I wonder if the two of them may have won some sort of an award, as well. What if the two of them were expected to kiss, too?"
"I have kissed my parents, before," Harmony replied, "but not in a romantic kind of way. If we just pecked each other, they may not have considered it a 'real' kiss."
"I see what you mean, Harmony," Marty replied. "At least, Jennifer already that she was with her son. It wasn't the case with me, back when I was stuck in 1955."
"Shortly after you leave," continued Harmony, "I should maybe talk with your older self for a little while. I wonder if he might suddenly remember what just happened."
"I'm ready, now, guys!" Doc announced, as he walked into the living room. "Marty, you're all set. The time circuits are all fixed up. I looks like I was able to finish this up in the nick of time. Now you should probably head back to 1986 at 11:30 on the seventeenth of this month. You will then arrive precisely 24 hours after you left."
"Hey, Doc," Marty asked, "what would happen if I headed back to that time on the sixteenth? I mean, that way, I could arrive to the same moment that I left."
"It could create a paradox," Doc replied. "It's better that you head back exactly one day later. That way, the space-time continuum will remain preserved."
"Well, I guess this is good bye, for now," Marty said, as he turned to hug Doc. After that, he turned to Harmony and gave her a hug. "Take good care of yourselves!"
"Can't I come to Hill Valley Park with him?" Harmony asked, "so that I could see him leave? Then, that way, I could wait around for his son to return. As nice as it really is to see Marty Sr as a teenager, I'll be so happy to see Marty Jr again."
"No, it's better if we stay here," Doc replied. "Marty Jr will probably head back here, as soon as he returns from 1986. I hoped he remembered to pick up the items that I asked him to get. I'm wondering if I maybe should have just headed back to 1986 by myself. That way, we may have been able to prevent this disaster from happening."
"Well, what's done is done," Marty said, smiling. "I guess I'd better be getting out of here, before the ripple effect catches up. I'll see you guys again in the future."
"Or in the past," Harmony said, smiling. "Have a safe one, Marty. Good bye."
Marty smiled and waved to Doc and Harmony once more, before he quickly stepped into the DeLorean. He decided to check the time circuits thoroughly, to be sure that everything was working as they should. The flux capacitor was working, too. Marty's heart was racing wildly, as he drove towards Hill Valley Park. As soon as he reached 88 miles per hour, the DeLorean broke the time barrier - with two minutes to spare.
