As soon as everyone arrived at the park, Marty was feeling a little excited. He was quite pleased that both he and his interdimensional twin ended up with such lovely children. He was rather curious about who Calvin's future wife would be.
"Can we put on Led Zeppelin, now?" Alex asked, as lifted a portable radio from the book bag - complete with what appeared to look like a CD player. "I have the Led Zeppelin II disc right here. I think we really need to Led out, everyone!"
Marty smiled, as he watched the other three kids squeal with enthusiasm. He had no idea what kind of music would be popular in the future, but he was pleased that their children had an appreciation for great rock music. He remembered being a huge fan of Led Zeppelin himself, when he was younger - even though it was during the '70s.
"Sure, honey," Jennifer replied, smiling. "Why don't you set the radio on the table, and we can put the disc in. You know, it's so nice that you kids have great taste in music. I myself didn't really get into music until I was around ten. I mean, I pretty much did listen to what my parents had on the radio - but I never got into it!"
The children ran over to the table, as they prepared to put the CD in. Within just a few seconds, the song Whole Lotta Love filled the air. Marty then remembered The Lemon Song, and he wondered if that song may be a bit too raunchy for the kids to listen to. After all, did they really want their kids to be singing "squeeze my lemon until the juice runs down my leg" out on the school playground?
The children then got out their hoverboards, as they began to hover around the playground area. Marty felt a little pang of envy, as he wished that he could ride around town on a hoverboard. It seemed nice to have to have any pavement to hover around on, and it would also save on gas. He just couldn't hover on water.
"It looks like you kids are having a lot of fun," Marty said, smiling. As the kids all waved to Marty, he smiled at them, and said, "You know, I sometimes wish I could be a kid, again. I can see why you kids love spending time on your hoverboards."
"Hey, Daddy! Daddy!" called out Marlene, as she stepped off her hoverboard and ran up to Marty. "Can you push me on the swing for a little while? I really would like you to give me an underdog! I always like it whenever you give me an underdog."
"Yeah, I sure can," Marty replied, smiling. It was nice to know that some things would stay the same. After Marlene held the chains of the swing, Marty began to push her a few times. He finally gave her a big push, as he ran under the swing.
"This is fun, Daddy!" Marlene squealed. "Can you give me another underdog? This is fun, being able to go so high. What do you thing would happen, Daddy, if I actually went over the swingset? Do you think I would enter into some alternate reality?"
Marty burst out laughing, as he replied, "I don't think so, honey! If you were to go over that swingset, I think you would get seriously injured - and your mom and I wouldn't want that to happen to you. I'll give you another underdog, but I wouldn't make it a goal to go over the swingset. We really want to see you grow up!"
"Could you give us a push, too, Daddy!" Marty Jr called out, as he ran up towards Marty. Mike and Alex were with him. "We want to go on the swing for a little while, too. We all want you to give us an underdog, as well. Those are really fun."
"I think we can do that for you," Marty replied, smiling. "It looks like there's enough for each of you to have one swing," Marty added, teasingly. Turning towards Mike and Alex, he added, "I'm sure your daddy will be happy to give you two a push."
"Oh, I'd be more than happy to do that," Calvin said, smiling. As the three boys ran towards the swingset, they each grabbed a swing and held on. Calvin then smiled at Marty, and added, "It looks like our children really love to swing high, don't they?"
"Oh, they certainly do," Marty replied. "Marlene asked me what would happen if she went over the swingset, and I told her that it wouldn't be a very good idea. We sure wouldn't want to see our precious little children get hurt, do we? We want our pretty darlings grow up to be as big as us - and maybe have children of their own, right?"
oooooooooo
"Well, kids," Marty called out, "we both have to get going, now. We both, uh, have a meeting we need to attend. I'm quite sure we'll be able to spend more time with you tomorrow, though. In the meantimes, you kids behave yourselves, okay?"
"That's right," Calvin added, "you kids have been real well-behaved this afternoon, and we are so proud of you. Just make sure you do whatever your mother or Aunt Jennifer tells you to do. Matbe we can do something special together on Saturday!"
"That sounds like great fun, Daddy," Alex and Mike called out, as they threw their arms around Calvin. Marty smiled warmly, as Calvin hugged the boys back.
"We love you, Daddy," Marty Jr and Marlene called out, as they threw their arms around Marty. Marty smiled, as he pulled his children close to him. His heart then swelled with great affection for his very precious future children.
Just then, Alex and Mike switched places with Marty Jr and Marlene - as they threw their arms around Marty and gushed, "We love you, Uncle Marty!" Marty felt a real strange sensation - as if they could be his children, too. Then he remembered that Calvin was his interdimensional twin from the Biffhorrific timeline.
"We love you, Uncle Calvin," Marty Jr and Marlene gushed, as they threw their arms around Calvin - who, in turn, hugged them tightly. Marty had a good feeling that he and his twin were headed towards a very wonderful future, with wonderful children.
Marty and Calvin waved towards the kids and Jennifer, as the two of them headed towards the trails, as they started to look for where they hid the DeLorean. Marty felt a little sad about leaving his future children and nephews behind. On the other hand, though, it felt good to know that he would have something to look forward to.
"I still wish I could've found out who my future wife is," Calvin commented. "I must say that I really am dying of curiousity." After taking in a deep sigh, he added, "At least, I can really look forward to knowing that I'll have some lovely twin boys in the future. I certainly wonder how our future children will be able to tell us apart."
"Oh, probably the same way as everyone else can tell us apart," Marty said, with a smile. "Maybe, on April Fools Day, you and I can switch places. Even though we are technically the same person, we have had very different life experiences."
"Well, I'm so amazed by how much you and I have in common," Calvin replied. "It's so nice knowing that I'm actually destined to have twins. What's even more amazing, though, is how much they both resemble Marty Jr. This is just so awesome!"
"I wonder what Dave's and Linda's children will be like," Marty commented. "I sure wonder if any of them might be the same age as our children. I wonder if Linda may end up marrying either Craig, Greg, or Paul. It probably won't end up being either of this as... well, technically, she's cheating on all of them. That's ultimately not good."
"Well, Marty, you do have a point," Calvin said, laughing. "Well, I see our DeLorean now. We might as well head in, now - and then head back to the year 1986. As nice as the future is, 1986 is the year that we really belong in. You have the packages?"
"Oh, yes," Marty said, smiling, as he lifted up the bags. "I remember how, in the old timeline, Linda was complaining about how he could never get a girlfriend. It really is amazing just how much all of that has change, all because I went back to 1955."
"Linda was a hooker," Calvin explain, as he stepped into the DeLorean, "in the world that I came from, and Dave was just a drunken bum. Biff really did a lot to turn this peaceful town into a wild and sleezy town. It's quite sad how he had such disrespect for everything that the town once stood for. I'm so happy to be out of that world!"
"I'm happy for you, too," Marty replied, as he turned the time circuits on. "I think we should really get back home at 12:30 PM." After a brief pause, he added, "The time circuits are on, the flux capacitor is fluxing, and the engine is running." After turning to Calvin, he added, "Okay, Calvin, brace yourself for temporal displacement!"
Marty then hovered the DeLorean, until they were far above the trees. He began to accelerate the DeLorean to 88 miles per hour, until it broke the time barrier.
