After Calvin, Marty Jr, and Griff's gang left the Cafe 80s - Marty finally stepped out from behind the counter. He gazed outside, and saw Marty Junior and Calvin flying on some strange flying boards, trying to escape from Griff's gang. Go on, Calvin, you can do it, urged Marty. Gradually, Marty began to remember a little more about his twin. Trying to set his memories straight was giving Marty a headache.
Suddenly, there was crash in the front door of the Courthouse Mall. What the hell was that? Marty thought.
Marty then decided that it was safe to leave the Cafe, and he decided to head on over to the Courthouse Mall, to see what the commotion was.
oooooooooo
Biff glanced up from waxing Griff's car, and he saw the boy who appeared to be Marty Junior leaving Cafe 80s. But Biff had distinctly remembered him leaving the Cafe awhile back.
'What the hell is going on here?' demanded Biff, to no one in particular.
oooooooooo
As Marty was heading over to the Courthouse Mall, he heard some elderly man proclaim: 'Save the clock tower!'
The elderly man then approached Marty and, holding out some pad, said, 'Hey kid, thumb a hundred bucks, will ya? Help save the clock tower.'
'I... Sorry, no,' stammered Marty.
'Come on, kid,' the elderly man protested, 'That's an important historical landmark.'
'Look, some other time,' said Marty, as he turned to walk away.
'Lightning struck that thing sixty years ago,' the elderly man continued.
Then where Goldie Wilson III's advert was earlier, a 'Sportsflash' holo-announcement started. It said that the Chicago Cubs had beaten the Miami Gators in the World Series.
'Wait a minute,' gasped Marty, shocked. 'Cubs win World Series - against Miami?'
'Yeah, something, huh?' asked the elderly man. 'Who would have thought? 100 to 1 shot. I wish I could go back to the beginning of the season and put some money on the Cubs.'
'No, I just meant, Miami...' Marty started to say, then he thought of something. 'What did you just say?'
'I said I wish I could go back to the beginning of the season, put some money on the Cubbies!' repeated the elderly man, as he began to walk away.
Marty then had an idea, as he headed off for the Blast From The Past antique store.
oooooooooo
At the antique store, the saleswoman took the almanac from the window and gave it to Marty.
'Now, this has an interesting feature,' the saleswoman was saying to Marty. 'It has a dust jacket. Books used to have these to protect the covers, of course that was before they had dust repellent paper. And if you're interested in dust, we have a quaint little piece from the 1980's, it's called a Dustbuster'
oooooooooo
As Marty was looking at his purchase outside, Doc arrived in the DeLorean, hovering over the shop.
'Marty!' shouted Doc.
'I can't lose!' Marty exclaimed.
'Marty, up here!' called out Doc, then he whistled.
Marty turned around, and he saw Doc. He asked, 'Doc, what's going on?'
'Stand by,' Doc instructed. 'I'll park over there.'
oooooooooo
As Biff left the cafe, he heard the boy who appeared to be Marty Junior saying, 'Yeah, all right. Hey, right on time.'
'A flying DeLorean? I haven't seen one of those in...' Then realizing something, Biff muttered, '... thirty years.'
Calvin Jr then left the Cafe, accidentally bumping into Biff.
'Sorry, excuse me, sorry,' Calvin Jr mumbled.
Calvin Jr went out into the road - and a car almost hit him. It beeped its horn at him.
'Don't drive tranked, low-res, scuzzball!' shouted Calvin Junior.
Then Biff sneaked up behind the DeLorean, and he listened in - unseen by either Marty or Doc.
oooooooooo
When Marty was in the DeLorean, he said 'hi' to Einstein, Doc's sheepdog.
'I left him in a suspended animation kennel,' Doc explained. 'Einstein never knew I was gone!'
Then, after getting out of the DeLorean, Doc shouted, 'Marty! What in the name of Sir Isaac H Newton happened here? Where is Calvin?'
'Oh, yeah, Doc,' replied Marty. 'Listen, my kid showed up - all hell broke loose.'
'I was afraid of this!' gasped Doc. 'Because I used it on Calvin Jr first, there wasn't enough power left to knock your son out for the full hour. Damn!'
Then Marty looked at the USA Today newspaper. 'Doc, Doc, Doc, look at this! It's changing!'
The newspaper was changing from 'Look-Alike Cousins Arrested' to 'Gang Arrested'. The picture of Marty Junior and Calvin Junior changed to one of Griff and his gang. At the Courthouse, Griff and his gang were being led away by the cops. Doc looked at them through his futuristic binoculars.
'Get off, go on!' shouted the blonde.
'I was framed!' insisted Griff.
'Why, yes! Yes, of course!' exclaimed Doc. 'Because this hoverboard incident has now occurred, Griff now goes to jail. Therefore, your son and nephew won't go with him tonight - and that robbery will never take place. Thus history, future history, has now been altered - and this is the proof! Marty, we've succeeded - not exactly as I'd planned, but no matter. Let's go find Calvin and go home!'
Marty greeted Einstein again, 'Hi, Einie - hi, buddy!'
Marty then picked up the almanac in its bag, but the book fell out and landed at Doc's feet.
'What's this?' asked Doc.
'Uh, it's a souvenir, a book,' stammered Marty.
'50 years of Sports Statistics. Hardly recreational reading material Marty,' protested Doc.
'Hey Doc, what's the harm of bringing back, er, a little info on the future?' Marty asked, defensively. 'Thought maybe we could place a couple of bets.'
'Marty!' shouted Doc. 'I didn't invent the time machine for financial gain. The intent here is to gain a clear perception of humanity. Where we've been, where we're going. The pitfalls and the possibilities. The perils and the promise. Perhaps even an answer to that universal question, why?'
'Hey, Doc, I'm all for that!' said Marty, defensively. 'What's wrong with making a few bucks on the side?'
'I am going to put this in the trash!' Doc said, with authority. Doc ran over to the alleyway, and put the almanac into a moving bin.
'Okay, Marty,' Doc said, with a sigh. 'Do you have any idea where Calvin went?'
'No, not really,' said Marty, shaking his head. 'The last thing I know is that he and my future son were on chasing away from Griff's gang on some flying boards.'
'Great Scott!' gasped Doc. 'I wondered if Calvin followed your son over to your future home. I remember that your parents were coming over to visit tonight. Calvin could conceivably encounter his future self, the consequences of that could be disastrous.'
'Doc, what do you mean?' asked Marty.
'I foresee two possibilities,' explained Doc. 'One - coming face-to-face with himself thirty years older could put him into shock, and he could simply pass out. Or two - the encounter could create a time paradox, the results of which could cause a chain reaction that would unravel the very fabric of the space-time continuum and destroy the entire universe. Granted, that's the worse case scenario. The destruction might, in fact, be very localized, limited to merely our own galaxy.'
'Well, that's a relief,' Marty said, somewhat sarcastically.
'Let's go!' urged Doc. 'I sure hope we find Calvin before he finds himself!'
Doc looked at a sign which gives information on the skyway. It said "Skewed on Skyway C25".
'The skyway's jammed, it's going to take us forever to get there,' groaned Doc. 'Well, let's go!'
oooooooooo
After Doc and Marty took off in the DeLorean, Biff opened the door, saw the almanac, and picked it up.
'So, Doc Brown invented a time machine,' Biff muttered, to himself.
