Amanda was stunned, as she woke up. She couldn't figure out where she was, or how she got here.

'How are you feeling?' asked a familiar voice. 'It appears you did have quite a shock. You have been out for almost three hours. Everything will be all right. I would just like to know who you are, though.'

Amanda glanced at the boy who was sitting next to her bed. He looked just like Michael J Fox - except it could not be. He was far too young. Then she remembered what had happened. This boy was none other than Marty McFly!

'You, uh, you're Marty McFly,' Amanda said, stunned. 'My name is Amanda Lynn Martini. It's so nice to meet you.'

'Actually, my name is Calvin,' replied the boy. 'Marty is my twin. He's out with Jennifer right now. So how did you find out about us? I can't say that I've ever seen you before.'

Amanda was stunned. Since when did Marty McFly did a twin? There was never any indication in the trilogy that Marty ever had a twin - unless Marty did some more time travelling that caused him to gain a twin.

'Are you all right, Amanda?' Calvin asked, gently. 'We want to help you, but we need to know where you came from.'

Amanda swallowed a bit, as she was uncertain of what to tell Calvin. 'Listen, Calvin,' Amanda said, 'do you, by any chance, know anything about a time machine that was created out of a DeLorean? It was first powered with plutonium, and then it was replaced with Mr. Fusion from the early 21st century.'

Calvin suddenly went pale, as he stammered, 'How... how... how did you find out about that? Did you, by any chance, come here from the future? Are you maybe my future daughter, or something?'

'Yeah, I'm from the future,' Amanda said, quietly. 'I'm not your daughter, though. I did come here from a different reality, as well. I came here from a reality where Marty and Doc were the subject of a movie trilogy. It was called Back to the Future. Michael J Fox starred as Marty, and Christopher Lloyd appeared as Doc.'

'You have got to be kidding me!' gasped Calvin. 'Marty is really going to freak out, if he hears about this. So are you telling me the truth? This world exists because of a movie someone created in another universe. I find the idea to be very far-fetched. Although, granted, many have said that Marty and I look just like Michael J Fox.'

'I do understand that it's hard to believe,' Amanda replied, blushing. 'You see, I was living at a foster home that was very restrictive. To make a long story short, I decided to run away from the home - and then I found the little computer device that told me I could visit a universe of my choice. I didn't think this thing would work, so I then entered Back to the Future - as there was a list of movies, TV shows, and books to choose from. Then, before I knew it, I found myself in this universe. I no longer have the device with me, though.'

'Well, I'm not sure what to say,' Calvin said, quietly. 'I know Doc had postulated about the existence of alternate realities before. I know there are some who believe that every alternate decision we can make could create parallel universes. I don't quite subscribe to that theory, though - as it does seem a little far-fetched. I mean, if I was to choose to go to bed half a minute earlier... well, actually, I could choose to go to bed any second that I'm at home. Would there end up being a parallel universe for each nanosecond I could have chosen to go to bed, or grab a bite to eat, or chosen what to eat? That would be, well, I can't really think of a word to describe it.'

'I don't believe in that, either,' agreed Amanda. 'Also, when you really consider how many living beings we have in this world that would be capable of making decisions - that would make it all the more complex. Then, just like you said, there are many other things you and I could be doing this second - besides discussing parallel universes. You know, this subject can be so mind-wracking.'

'Right, exactly,' Calvin said, nodding, 'then there are also the moral and ethical decisions to consider. I mean, if each version of me is supposed to be essentually the same person - then how can someone from a different universe who is suppose to be me not have the same values as me? Know what I mean?'

'That is such a good point, as well,' Amanda replied. 'Although, I have heard of a reverse world where everyone who is good is evil - and vice versa. I do not really believe that, though. I guess there is still that question of how parallel universes are created - and how many of them there would be.'

'There are probably not as many parallel universes as one would think,' replied Calvin. 'Maybe it is quite possible for there to be universes for different fictional worlds. Although, I never really dreamed that this world would be the product of a fictional movie from a different universe. Heck, I still have difficulties with being able to wrap my mind around that idea - although, I'm not sure how else you would have found out about the time machine.'

'So how did you end up becoming Marty's twin, anyway?' Amanda asked, quietly. 'I watched the trilogy, and there was never any indication that Marty had a twin. I mean, the closest to the idea was when Marty and Doc went back to the year 1955 to retrieve a sports almanac from Biff Tannen.'

'That's exactly where I come in,' blurted out Calvin. 'I came from the timeline where Biff was so rich and corrupt, and he was married to my mother. Doc was also committed in that timeline - but, his good friend, Sabrina helped him to be released. So the three of us went back to 1955 to take away the almanac. It was when we ended up meeting with our counterparts from the good timeline. So I then changed my name to Calvin, and everybody now knows me as Marty's twin brother, Calvin.'

'As Marty would say,' Amanda said, smiling, 'this is heavy! So is Doc still living in the Old West with Clara, now?'

'Who's Clara?' Calvin asked, stunned. 'Both Docs have stayed here in the present. The Doc from my timeline had gone into the future to get a rejuvination and alter his appearances, and he now calls himself Christopher Lloyd Brown.'

'That's an interesting choice for a name,' Amanda said, amazed. 'So does Chris call himself a brother?'

'No, he actually calls himself a cousin,' replied Calvin. 'You see, people would become real suspicious if both Doc and I ended up with twins. So Doc and Sabrina had to change their identities. I really wonder why this world is not matched up with the trilogy. It appears that your trilogy is a little different.'

Amanda thought for a minute, then she suggested, 'Maybe it is because the trilogy focused on the Marty who was from the timeline where the mall was called Twin Pines Mall and he came from an unhappy family where Biff had pushed his father around. Although, granted, I'm sure your life was even worse. I always wondered if Marty and Doc had doubles in the Hell Valley Universe. I guess now I know. So this world is the product of you and Doc going back to the year 1955 to prevent Doc from using the almanac to become rich.'

'Gee, I guess you're right,' Calvin said, smiling. 'Well, we'll have to tell Doc about this - and try to get you back home to where you belong. Everything will be all right, Amanda. So don't fret, okay?'

'But I don't want to go back,' protested Amanda. 'I hate the foster home I was in. They punished me, simply because I held political views that were different from theirs. They also don't let me listen to the music that I like.'

Calvin was silent for a minute, then he said, 'I understand how you feel, Amanda. I am really not sure if you could stay here, though. I mean, you really don't belong in this dimension - and where would you stay?'

'You don't belong in this dimension, either, though,' Amanda pointed out, 'and you're doing fine. So why couldn't I stay here, too?'

'Well, I came here through the result of time travel,' explained Calvin. 'Your situation seems a little bit different from mine. We'll talk with Doc, though, and see what he says. I'm sure we can work something out, though. You shouldn't have to be forced to stay in that awful foster home.'

Amanda glanced at Calvin, and forced a little smile. He was so cute, and she hoped he was single. It was so amazing that this world actually contained two versions of Marty!
