1:30 AM PST
As Doc had predicted, his lab was indeed a huge mess.
'I went to the public library to try and make sense out of all the madness,' Doc 2 was saying. 'The place was boarded up, shut down - so I broke in and borrowed some newspapers.'
'I don't get it, Doc,' Marty 2 said, confused. 'I mean, how can this be happening? It's like we're in hell or something.'
'No, its Hill Valley,' replied Doc 2, 'although I can't imagine hell being much worse!'
Then Einstein began to whine. Doc 2 took a candle and walked over to him.
'Oh, Einie, I'm sorry, boy,' Doc 2 said, with regret, 'the lab is an awful, awful, awful, awful mess!'
'You can say that, again,' muttered Doc.
Then Doc 2 got Einstein's basket, and Einstein stepped inside.
'Atta boy.' Then, turning to Marty 2, Doc 2 said, 'Obviously the time continuum has been disrupted creating this new temporally venced sequence resulting in this alternative reality.'
'English, Doc!' pleaded Marty 2.
'Yes, please,' added Marty.
Then Doc 2 found a chalkboard, and began to explain to Marty 2 about the disruption in the timeline. The astral travellers listened intentively.
Then Doc 2 grabbed a bag from the almanac, and asked Marty 2, 'Recognise this? It's the bag the sports book came in. I know, because the receipt is still inside. I found them in the time machine, along with this!'
'It's the top of Biff's cane,' said Marty 2, stunned. 'I mean, old Biff from the future!'
'Correct!' replied Doc 2. 'It was in the time machine, because Biff was in the time machine - with the sports almanac!'
'Holy shit!' gasped Marty 2.
'You see,' explained Doc 2, 'whilst we were in the future, Biff got the sports book, stole the time machine, went back in time - and gave the book to himself at some point in the past.'
'Looks like my theory was correct,' muttered Doc.
Doc 2 turned back to the chalkboard, then he took out a copy of Hill Valley Telegraph, the one that was headlined 'Hill Valley Man Wins Big At Races'.
'Look!' Doc 2 said, with a little chuckle, 'It says, right here, that Biff won his first million betting on a horse race in 1958. He wasn't just lucky, he knew because he had all the race results in the sports almanac. That's how he made his entire fortune! Look in his pocket with a magnifying glass.'
'The almanac!' breathed Marty 2, as Doc 2 chuckled again. Then, raging, Marty 2 added, 'That son of a bitch stole my idea!' After Marty 2 pounded his fist on the table, he shouted, 'He must have been listening when I...' Then, in sudden realization, Marty 2 muttered, 'It's my fault! If I hadn't bought that damn book, none of this would ever have happened!'
'What?' gasped Marty, astonished. 'The book was my counterpart's idea?'
'Apparently so,' replied Doc.
'Well, that's all in the past,' said Doc 2.
'You mean the future,' protested Marty 2.
'Whatever!' Doc 2 cried out, with frustration. 'It demonstrates precisely how time travel can be misused and why the time machine must be destroyed - after we straighten all of this out.'
'Right, so we go back to the future,' suggested Marty 2, 'and we stop Biff from stealing the almanac.'
'We can't!' said Doc 2. 'Because, if we travel into the future from this point in time, it will be the future of this reality!' He underlined 1985-A on the board. 'In which Biff is corrupt, and powerful, and married to your mother; and in which this has happened to me!' Then Doc 2 held up the newspaper that was headlined 'Emmett Brown Committed - Crackpot Inventor Declared Legally Insane'. Then Doc continued, 'No, our only chance to repair the present is in the past, at the point where the timeline skewed into this tangent. In order to put the universe back as we remember it, and get back to our reality, we have to find out the exact date, and the specific circumstances of how, where and when, young Biff got his hands on that sports almanac.'
'I'll ask him,' Marty 2 said, quietly.
'I guess this means we follow my counterpart back to Biff's Pleasure Paradise,' Marty said, sighing.
'We'll finally get an answer,' commented Doc.
oooooooooo
The astral travellers followed Marty 2 over to the jacuzzi, where he was watching a Clint Eastwood western with two ladies. Marty 2 grabbed the remote, and shut off the TV.
'Hey, what the hell's going...' demanded Biff. Then he saw Marty 2, and screamed, as did the ladies.
'Party's over Biff,' insisted Marty 2, throwing the remote into the jacuzzi. 'Sorry, ladies.'
'How'd you get past my security downstairs?' demanded Biff.
'There's a little matter we need to talk about,' Marty 2 said, firmly.
'Yeah, money, right?' asked Biff. 'Well forget it!'
'No, not money.' Then slowly, Marty 2 said, 'Grays Sports Almanac.'
Biff was then horrified. He turned to the ladies, and said, 'You heard him, girls - party's over.'
'I guess we'll soon find out,' muttered Marty.
oooooooooo
'Start talking kid,' demanded Biff. 'What else do you know about that book?'
'First, you tell me how you got it.' Marty 2 said, firmly. 'How, where, and when.'
'Alright, take a seat,' ordered Biff. Marty 2 remained standing. 'Sit down!' shouted Biff. Marty 2 finally did. 'November 12th 1955, that was when.'
'Imagine that,' gasped Doc. 'What a coincidence!'
Biff then revealed that the painting was really a safe! He opened the safe.
'November 12th 1955? That was the day I went back...' Then, covering, Marty 2 finished, 'that was the day of the famous Hill Valley lightning storm.'
'You know your history, very good.' said Biff. 'I'll never forget that Saturday. I'd just picked my car up from the shop because I'd enrolled it in a drag race a few days earlier.'
'I thought you crashed it into a manure truck,' insisted Marty 2.
'How do you know about that?' demanded Biff.
'My father told me about it,' Marty 2 lied.
'Your father?' Biff asked, suspiciously.
'Before he died,' added Marty 2.
'Yeah, right,' snorted Biff, doubtfully. 'So there I was, minding my own business...' He then opened the safe, '... when this crazy old codger with a cane shows up.' Then Biff took a box out of the safe. 'He says he's my distant relative,' snorted Biff. 'I didn't see any resemblance.' He puts the box on the table. Biff continued, 'So he says, 'How would you like to be rich?' So I say, 'Sure.' Biff then opened the box and took the sports almanac from it. 'So he lays this book on me. He says this book'll tell me the outcome of every sporting event 'til the end of the century. All I have to do is bet on the winner, and I'll never lose. So I say, 'What's the catch?' He says, 'No catch, just keep it a secret.' Biff then put the book back in the box and closed it. 'After that, he disappeared. I never saw him again..
Marty 2 took a 'Biff's Pleasure Paradise' matchbox and put it in his pocket.
'Oh, and he told me one other thing. He said some day, a crazy wild eyed scientist or a kid may show up asking about that book. And if that ever happened...' Biff laughed, as he pulled out a gun. 'Funny, I never thought it would be you.'
'Yeah, well, Biff, you're forgetting one thing.' Then Marty pointed behind Biff, and asked, 'What the hell is that?'
The astral travellers then watched, as Marty 2 began to run away from Biff and his gang. Marty's astral heart was racing, as he saw his counterpart desperately trying to escape. Then he heard Biff admit to shooting George McFly.
'That bastard!' seethed Marty. 'He did kill my father! Just as I thought!'
Then Marty and the other astral travellers saw his counterpart standing on a flying DeLorean. Doc 2 then opened the door of the car, and it hit Biff on the head, knocking him out. Marty 2 then climbed in. Then the DeLorean flew off, until it disappeared.
'So I guess that DeLorean was a time machine,' gasped Marty. 'They must have headed back to 1955.'
'Well, now we know what to do,' said Doc, 'once I finish building my time machine.'
'Well, let's head back to our bodies, now,' suggested Sabrina.
Then all four of them had re-entered their bodies.
