Just as Sabrina had predicted, as soon as the DeLorean had broken the time barrier, they landed in Hill Valley.
'Okay, Doc and Marty,' said Sabrina, 'you two just stay here. I'll take care of Biff and rescue the other Marty from the garage. Then the four of us can find the other Doc.'
'That works for me,' Doc said, softly. 'By the way, we should just hold onto the almanac, until we discuss with my counterpart about what should be done with it.'
'Check, Doc,' Sabrina said, smiling. Then she headed off to the Tannens' home.
oooooooooo
'What the hell are you doing in my bedroom?' Biff snapped, as soon as Sabrina walked in.
Sabrina stared hard into Biff's eyes, putting him into a hypnotic state.
'Give me the almanac,' ordered Sabrina.
Biff stood up, glassy-eyed, walked over to his desk drawer, pulled out his almanac, and handed it to Sabrina.
'When you awake in 15 minutes,' said Sabrina, 'you have no memories of the almanac, then old man who gave the almanac to you, or me.'
Then, as Biff fell into a deep sleep, Sabrina slipped downstairs - and headed out to the garage. She used her telekinetic powers to pick at the padlock, then she quietly entered the garage. She saw that the other Marty was lying face down in the back of Biff's car, and he was crying.
'Hey, Marty,' whispered Sabrina. 'I'm Sabrina! I came here to rescue you.'
Marty lifted up his tear-stained face, and gazed intentively at Sabrina. 'How can you be here, Sabrina?' Marty asked, swallowing.
'I came here to help you,' Sabrina said, softly, as she gently laid her hand on Marty's shoulder.
Marty began to cry again, as he said, 'I swear, I have never encountered so much bad luck in my life before. Time travel is a real pain.'
'It's okay, Marty,' Sabrina said, soothingly. 'I came here to help you. Just follow me okay.'
Marty then climbed out of the car, and hugged Sabrina for about a minute. Then Marty wiped his face with the back of his hand, and gave Sabrina a little smile.
'Everything will be fine, Marty,' Sabrina whispered. 'I came here from the world that you just came here from. The world where Biff is rich and married to your mother.'
'Wha-what?' stammered Marty. 'You're not the Sabrina that I know?'
'I came here with your counterpart, and Doc's counterpart,' explained Sabrina. 'We don't like that world, either - and we're hoping to return to a better future.'
'Gee, this is heavy,' mumbled Marty. 'I wonder what Doc, my Doc, would say about this. I certainly never expected something like this to happen.'
Then, as they returned to the DeLorean, Sabrina said, 'Hey, Doc and Marty. I found the other Marty. Now we have to go find the other Doc.'
The two Martys then stared at each other. Then they embraced.
'Say, do you mind being called Calvin?' Marty 2 asked his counterpart. 'That way, we can avoid confusion.'
'Yeah, sure, I guess,' stammered Marty. 'I will certainly miss being Marty, though. Still, I guess it is just a name.'
'Why can't you be Calvin?' asked Doc, baffled. 'I mean, you were already Calvin, when you were here for a week.'
'Because, if we wish to prevent Biff from ever being rich and powerful,' explained Marty 2, 'we will most likely return to a world that I'm more familiar with - and where Jennifer is my girlfriend.'
'I guess that sounds plausable,' remarked Doc. 'I mean, our Marty is not dating a Jennifer - or anyone, for that matter.'
'We should be looking for Doc, now,' suggested Marty 2.
oooooooooo
Doc was riding his bike over to the Tannens' garage, when he saw something that shocked him. He saw his counterpart, who looked the same way he used to look, before getting the rejuvination in 2015 - accompanied with another Marty, and Sabrina
'Great Scott!' gasped Doc, nearly about to faint. Fortunately, his counterpart had steadied him
'Let's head over to me DeLorean,' suggested Doc's counterpart, 'then we'll explain everything to you.'
'Where did you guys come from?' asked Doc.
'We came from the same world you just came from,' explained Doc's counterpart, 'the world where Biff is rich and I've been committed. Sabrina was able to grab the almanac from Biff - and give him a hypnotic suggestion to make him forget about the almanac, old Biff, or her. I thought that we should hold onto it, until we consulted you.'
'We decided that I should be called Calvin,' added the second Marty. 'I guess we'll have to explain to my parents about the time machine, as there will probably be two of me when we return to 1985.'
'That also means there'll be two of me,' added Doc, 'and two of Sabrina - even though our Sabrina didn't come with us.'
'So, shall we go burn the almanac, now?' asked the second Doc.
'Yeah,' agreed Marty, 'then we should get our asses back to the future.'
'We might as well,' agreed Doc. 'We should get leaving, before the storm comes.'
Marty then spotted an old bucket. He put the almanac in the bucket and took out the matchbox he took from Biff's Pleasure Paradise. He lit a match and started to burn the book. He then looked at the matchbox. The words were starting to change! Eventually, they changed from 'Biff's Pleasure Paradise' to 'Biff Auto Dealing'. Marty then pulled out the newspaper. The headline changed from 'George McFly Murdered' to 'George McFly Honoured'.
'Doc, Doc, the newspaper changed!' exclaimed Marty. 'Now my father's alive! That means everything's back to normal, right?'
Doc then pulled out the newspaper he had. The headlines changed from 'Emmett Brown Committed' to 'Emmett Brown Commended', 'Nixon To Seek Fifth Term' to 'Reagan To Seek Second Term', and 'Biffco Builds New Dioxin Plant' to 'Mayor Wilson Vetoes Zoning Bill'.
'Mission accomplished,' whispered Doc.
'That means Jennifer's okay and Einie's okay, right?' asked Marty.
'That's right, Marty!' replied Doc. 'It's the ripple effect, the future is back. Now let's go home!'
'Right, Doc,' agreed Marty, 'let's get our asses back to the future.'
'So should we,' replied the second Doc. 'The only question is, what day should we return to?'
'How about October 27 at 11:00 AM?' suggested Doc. 'We'll meet in my garage, and we can work out where to go from there.'
