Calvin McFly smiled warmly at his twin, Marty - as they stepped into the roller rink. He sure had anticipated this day for quite some time. After this, this was the day that he and his twin would finally become legally recognized as adults. Their parents reserved the entire evening for friends and family, as they recognized this as a major event.

This would also be Calvin's first birthday celebration in this world - the world where his father was alive and successful, his mother was so perky, and he had a happy family. He no longer had to live under the tyranny of a powerful and corrupt Biff Tannen.

"Isn't this simply exciting, Cal?" Marty asked, with enthusiasm. "We are now officially eighteen years old, and they're even going to play some of our songs. Y'know, I can hardly believe that we're now adults. The thing is, I don't feel that much different."

"Me, either," Calvin replied, softly. "It's very scary, though. I know that, technically, we're already a little older. Still, I'm not sure that I'm ready for adulthood. After all, I only had a real family for about eight months - and I don't quite want to give it up. It was my life-long dream to be able to have such a family. Know what I mean, Marty?"

"Don't worry, honey," Lorraine replied, as she placed her arms around Calvin. "Even though you are legally an adult, we sure have no plans to kick you out. The thing is, your dad and I understand that you didn't have a very easy life - and we really..."

"We understand how big of an event it is for you," added George, softly. "That's why we decided to go out of our way to plan this skate party for the two of you. This time travel stuff can still be rather confusing, but the two of you are real precious to us."

"No more talk about time travel, George," Lorraine chided, gently. "C'mon, boys! Your friends are starting to show up. We want you guys to have fun. You should be pretty excited about your next milestone. You'll be able to vote, this year - and you'll just be able to help us keep Goldie Wilson elected. He's one of the greatest mayors around."

"That's very true," replied Marty, flashing a lopsided smile. "Well, other than the fact that he sure keeps wanting to replace the clock tower. Still, most of his other policies are wonderful. Besides, his competitor has also expressed wanting to replace the..."

"Man, if we can just find a candidate," added George, sighing, "who actually cares to preserve our town's most legendary landmark. Well, I suppose we shouldn't fault him too much. I mean, back when he worked at Lou's Cafe, he certainly was a nice guy."

"Hello, everyone!" called out Dr. Emmett Brown, as he went to join the group. "Chris should be here very soon, as well. I must admit that I'm a little rusty at rollerskating, but I'll give it a shot. I sure remember the day that I turned eighteen. It seems like it was just yesterday. Of course, with a time machine, I guess I could also go back..."

"That might not be a very good idea," Calvin replied, doubtfully. "I mean, you're the one who's always mentioning that one must be very cautious with time travel - as to not mess up the space-time continuum. Also, it's not like you can de-age yourself."

"Well, there is the rejuvenation clinic," reminded Doc. "You have a point, though. It probably isn't possible to de-age someone too far back. Like, for instance, I'm quite sure it wouldn't be possible for me to... to go back to being, uh, five years old."

As everyone laughed at Doc's comment, Calvin began to think back to when he was five. It wasn't a rather happy time for him. By then, his father was dead - while his mother already married Biff Tannen. He simply remembered how disappointed he was, that he never had a birthday part that year. He felt that his life was so unfair.

"Now, that is an interesting thought!" Marty replied, chuckling. "It's very hard to imagine you as a little boy. I bet you were already quite intellegent. I do wonder how you and I would've gotten along, if we were both five. I never really thought of..."

"I really wish I could've had your life," Calvin added, sighing. "I bet, even in the original timeline, where your family wasn't as successful - it would simply beat having to live under the tyranny of Biff Tannen. I guess I just shouldn't dwell on the past."

"I'm sorry I mentioned that," Doc replied, softly. "Well, the past is prologue. Men like us have to keep looking to the future. Anyway, it simply looks like your band is doing good. I just think it's so nice, having the two of you being in the same band. I mean, having a rhythm guitarist seems to really add to the sound. You guys simply rock!"

"Emmett is right," added Christopher Lloyd Brown, as he walked up. "I know, people don't actually expect for us old fogeys to listen to hard rock - and, back in 1955, we were turned off by your music. However, we've simply come to understand your..."

"I still remember how scared George was," Marty replied, laughing. "It's so strange to think that, prior to November 12 of 1955, your lives were exactly identical. Well, now that we're all together... I see the DJ up there! There'll probably be music soon."

Almost as if on cue, the crackling of a microphone could be heard. "I'm real pleased to be able spin records for all you great folks on this nice evening. This is a private party that was reserved for Hill Valley's beloved twins, Calvin and Marty McFly. I quite think it would be fitting to start out with a nice song by The Pinheads. It's called Harmony."

Calvin and Marty flashed their identical lopsided smiles, as they began to head out to the skating floor. Calvin remembered, with such fondness, how he and his twin really wrote the song together. He felt pleased with how much of a hit that song became.

As the two of them started circling the floor, Calvin smiled at the song. It simply had a catchy beat, but it also had a very serious message. When he and Marty had been so disturbed by some of what they saw in the news, they had decided to write the song.

"Isn't this very awesome, guys?" asked Zach Nelson, and he and Zoe Quinn skated up to twins. "I still remember February 15. It was our very first concert in a major studio, and they sure enjoyed this song so much - we were asked to perform it, in an encore. I have a good feeling about this. We might not become the next Beatles, but we..."

"Nobody could ever compete with The Beatles," Calvin replied, laughing. "Even if we never do become famous, I'm quite in this for the music. Don't get me wrong. I think being rich and famous would be rather awesome, but it's really not my main goal."

"Well, I'd like to be famous," insisted Marty. "Even though, I suppose I see what you mean. With, uh, everything that you just went through... Well, I guess I really have to admit that you... With having you around, you do keep me grounded in reality."

"I do think Calvin's onto something," Zach pointed out, smiling. "Most of the time, you two simply seem to think so much alike... Well, I'd almost think that the two of you do share a mind. It sure seems as though the two of you are the same person. It's quite as though you have this closeness." Suddenly, he gasped, "It's The Power of Love!"

Calvin and Marty smiled at each other, as this was their very favourite song by their favourite group. He simply recalled how, back in his old world, Huey Lewis' band was Huey Lewis and The Rebels - and they really had a more punkish metal sound to it.

Just then, he caught sight of two people. One of them was Jennifer Parker, who was his twin's girlfriend. Next to her, there was a girl that he was quite sure he never met before. For some reason, though, he felt as though he was quite attracted to her.

"Marty! Calvin!" called up Jennifer, as she skated up to the twins. "Marty, I'm simply sure you remember my cousin. Anyway, guys, her name's Sarah. Sarah Parker. She and I were always rather close, and she is the daughter of Aunt Marlene. They plan to move back to town, in the outskirts. At any rate, she's real excited to be here!"

"I'm excited to be back," Sarah replied, in a lilting voice. She really looked a lot like her cousin. In fact, she bore a real strong resemblance to Elisabeth Shue - who Marty felt looked a little like Jennifer. "So, you both look real cute! Which one of you is Calvin?"

"I am," Calvin replied, as he gazed into Sarah's chocolate brown eyes. "I was, uh... I was here for nearly eight months. I was, uh, adopted at birth - but I sure hadn't had a good life. It feels so nice to be reunited to my long lost twin. We get along great."

"I'm quite sure you do," Sarah replied, as a soft smile tugged at her lips. "Say, I know I just met you... Well, I don't wish to seem too forward. Since my cousin will probably want to skate with your twin... Well, I don't have a partner - so I was just wondering if... Well, Calvin, will you skate with me? I mean, you just seem like such a nice guy."

"Sure, I would love to skate with you," Calvin replied, warmly. He didn't want to jump to conclusions, but he had a pretty good feeling that Sarah would be the right girl for her. He didn't even recall feeling that way about Felicia Hartman. "C'mon! Let's go!"

As Calvin and Sarah began to circle the floor, with Marty and Jennifer not far ahead, Sunglasses at Night by Corey Hart began to play. In his old world, the song sure had darker lyrics. In this world, though, he quite felt that the song was somewhat fitting.

Just as he and Sarah skated past Marty and Jennifer, they waved to the other couple - who quickly waved back. As he glanced at Sarah, he figured that this evening rather would be even better than he expected. From looking in Sarah's eyes, it quite seemed that she felt the same way. He felt rather optimistic about being eighteen years old.
