'Oh, my gosh!' gasped Melody, as she turned to her friend.
Jamie was shrinking by a few inches, and her brown hair was starting to turn blonde. Her dark brown eyes were turning into a bright blue. As Jamie began to faint, Melody quickly caught her.
'Great Scott!' everyone gasped, in unison.
'So who is that girl, anyway?' asked Clara, stunned.
'This is my sister, Jamie,' Harmony said, dazed. 'Oh, yeah, and my name is Harmony. We are your grandchildren. Jules is our father.'
Clara was about to faint, when Doc walked up to the gang.
'Hi, Clara,' Doc said, as he kissed her on the cheek.
'Emmett,' Clara said, shocked, 'you're home early! It's only quarter after four!'
'Well,' Doc said, 'they said everyone could go home early today, due to the power outage that happened from the lightning storm earlier today. They're hoping to have everything repaired by tomorrow, though.'
'Oh, I see,' Clara said, smiling. 'Well, at any rate, I'm so happy to see you.'
'So who are all these people?' Doc asked, as he looked around. 'Why are they here?'
'I'm Melody McFly,' explained Melody. 'I'm Marty and Jennifer's youngest kid.'
'You look just like Jennifer!' Doc exclaimed. 'Say, you didn't bump into any of your parents yet, did you?'
'Um, no,' replied Melody, 'but we did bump into a Tannen.'
'Great Scott!' gasped Doc, as his face went pale.
'What's wrong with that?' asked Melody, concerned.
'Oh, nothing, really,' Doc replied. 'It's just that these guys are bad news. Even Biff Tannen can be a bit of a jerk, when he's away from his customers. Both of his sons are real holy terrors, though. I swear that the Tannens have a bad gene in them.'
'Say, Emmet, do you know anything about Jamie?' Clara asked her husband. 'She just transformed in front of us, shortly before you came home from work.'
'Uh, no, not really,' replied Doc. 'The last time I travelled to 2015, it was to hover-convert the steam train. Of course, we have since moved here to 1985 - so I'm sure that would have changed the course of future events drastically.'
'You mean you haven't always lived in this era?' asked Harmony, stunned. 'Where did you guys use to live? It seems like there's a lot about you guys that I never knew before. What made you guys decide to move to 1985?'
'Look, Harmony, we'll explain later,' said Doc. 'First things first. So who is Jamie, and what is this about her transforming? I mean, in what way did she transform?'
'She's Jules' daughter,' explained Melody. 'She used to have brown hair and brown eyes, and she was five feet eight inches tall. Now she looks just like Harmony with short wavy blonde hair and bluer eyes. So I don't know what happened here.'
'Great Scott!' Harmony gasped. 'I just remembered! Jamie's father is Miff Tannen! She doesn't know that, though. Oh, no, what are we going to tell her?'
'What?' gasped Marlene and Melody. 'Miff Tannen is her father?'
'How did you find out about this, Harmony?' asked Doc, concerned.
'Okay, I admit it,' Harmony said, blushing. 'I found out by snooping around.'
'That's not very good, Harmony,' chided Doc. 'Well, I guess now is not the time to worry about that. The Tannen guy you ran in. Was his name by any chance Miff?'
'We don't know for sure,' replied Marlene. 'He could have been Miff or Cliff! I mean, I reckon they both look the same - just like Griff Tannen from 2016.'
'I think he was Miff,' Melody said, quietly. 'When he tried to take advantage of us, we began to beat the shit out of him - and we accidently broke his leg. That might explain why Jamie transformed in front of us. Gee, I hope we didn't hurt him too badly. I mean, I'm not especially fond of him - but, still, I never meant to hurt him.'
'Great Scott!' gasped Doc, horrified. 'This could be very disasterous!'
'Why would Jamie transform, though?' asked Clara, confused. 'If Miff ends up not being her father, wouldn't she just end up being erased from existence? I mean, you told me that that was almost what happened with Marty - when he interfered with his parents' first meeting in 1955. Right?'
'Yeah, that is true,' Doc said, stunned. 'Although, it might be possible that the egg she came from was fertilized with someone else's sperm.' Then, turning to the girls, Doc added, 'Why don't you girls check into her purse - and see if you can find some ID in there? We might be able to find some clues in there.'
'So, you mean it might be the same egg,' asked Clara, 'but a different sperm?'
'Whoa, this is heavy!' breathed Harmony. 'Well, yeah, if Miff never raped Mom - then Dad is probably now her father. Oh, boy, when Jamie wakes up - she's going to be very confused. I wonder how she's going to react to finding out that she is - or was, rather - Miff Tannen's kid. How are we going to break the news to her?'
'Here it is!' called out Melody, as she lifted up a card. 'I found her ID card. It says on here that her birthday is August 5, 1999 - instead of August 4, 1999. I guess this means Jules' sperm had fertilized the egg one day after Miff's sperm would have.'
'Of course!' gasped Harmony. 'Because Miff doesn't rape Mom at Haven's 13th birthday party - Dad ends up conceiving Jamie the next day. I'm pretty sure that's what happened.'
'Speaking of Haven,' Clara said, sighing, 'I'd better go check upon her. It's probably about time for her bottle. Gee, I'm afraid I might already know too much about my own future. Anyway, it's like Haven is our miracle baby, or something.'
'Or cosmic baby,' added Doc, smiling. 'I once suggested to Marty that November 12 of 1955 inherently contained some sort of cosmic significance. Almost as if it were the junction point for the entire space-time continuum. It is very uncanny how our third child and first daughter ended up being born exactly thirty years after the famous Hill Valley lightning storm - and shortly after we moved to this era, no less.'
'Huh?' asked Harmony. 'What are you talking about? I mean, I know that was the day of the famous Hill Valley lightning storm - but you might be reading too much into this. Well, other than the fact that Haven was born exactly thirty years later.'
'Actually, it goes deeper than that,' explained Doc. 'We'll wait until Marty and Jennifer come back, before we explain everything to you. Well, let's all go in the house now - and we'll bring Marty and Jamie into the spare bedroom.'
