As the time travellers broke the time barrier, and headed in 1955, Doc parked the DeLorean behind the Lyon Estates billboard - the same place where Marty had parked the car a week earlier.
'Ah, this is heavy, Doc,' said Marty, with a sigh. 'I mean it's like I was just here yesterday.'
'You were here yesterday, Marty,' Doc reminded Marty. 'You were. Amazing, isn't it?'
'Yeah, I guess,' said Marty, with a weary sigh.
'I can hardly believe we're in 1955, again,' remarked Jennifer.
'Now, remember, you guys,' said Doc. 'We are here to grab the almanac from Biff. Now, if my calculations are correct, Biff from 2015 should be leaving in seven minutes and 12 seconds. Then you guys go into town, and track down Biff and tail him. Also, you two must try to let either your parents or your younger selves either of you. Got it?'
'Got it!' Marty and Jennifer replied, simultaneously.
'Once Old Biff has gone,' cintinued Doc grab the almanac any way you can. Remember that our futures depend on this!'
'You don't have to remind me of that, Doc!' protested Marty.
'Here are some binoculars and a walkie-talkie for each of you - so we can all keep in contact,' said Doc. 'I'll stay here and try to repair the shortened time circuits. That way we don't risk anyone else stealing the time machine, and I won't risk accidentally running into my other self.'
'Your other self?' asked Marty, confused.
'Yes! There are now 2 of me here,' Doc explained, 'and there are 2 of each of you here. The other me is the Dr. Emmett Brown from 1955, the younger me that helps your younger selves get back to 1985! You two remember the lightning bolt at the clock tower?'
'Yeah,' answered Marty.
'That event doesn't happen for over three hours, so you two must be very careful not to run into your other selves,' explained Doc. 'Let me give you guys some money.' Doc then reached into his briefcase to pull out some money, and continued, 'Have to be prepared for all monetary possibilities! Get yourselves some 50's clothes.'
'Check, Doc,' replied Marty and Jennifer, simultaneously.
'Something inconspicuous!' Doc called after the teens.
oooooooooo
After a little while, Jennifer and Marty were wearing clothes that were most decidedly not inconspicuous. Marty was wearing a leather coat, glasses and a hat - while Jennifer was wearing a hot pink dress with pink bows in her haior. They went looking for Biff. Jennifer headed off for the school, while Marty looked for Biff's home.
As Jennifer went into the school, she was extremely careful to not run into her younger self or the younger Marty. She then heard Lorraine and Betty talking about that their plans for the evening.
'Isn't Todd Newman such a dreamboat?' Betty was gushing. 'I am so excited about this evening. I always felt that he was so handsome. So you're going to the dance with Huey Lewis?
'That is correct,' replied Lorraine. 'I can hardly believe that Huey Lewis broke up with Pat Benatar, though. I wonder what went wrong between them.'
Jennifer barely stifled a giggle as she heard Lorraine's remark.
'It's my understanding that they just needed some time away from each other,' Betty suggested. 'I don't think there's any real anomosity between them, though.'
'Hey, Lorraine, looking pretty sexy,' smirked a familiar voice.
Oh, no, Jennifer groaned inwardly. It's Dixon Nolan! I have to get out of here. Granted, Dixon wasn't quite a bad as Biff - but he was still a pretty nasty sort.
'Go take a long walk off a short pier, you pervert!' Lorraine shrieked at Dixon.
Jennifer went to hide in the ladies' washroom.
oooooooooo
'Doc, come in, Doc,' called Marty, on his walkie-talkie, 'this is Marty, over.'
'Roger Marty, this is Doc,' Doc answered. 'Are you there?'
Marty looked through the binoculars. He was looking at a house, filled with garden ornaments and a sign - No Trespassers - Violators Will Be Prosecuted. This Means You! Wow, so this is where Biff lives, eh?
'Yeah Doc, I'm at the address,' replied Marty, looking at the front door. 'It's the only Tannen in the book, but I don't think it's Biff's house. It looks like some old lady lives here.'
Just then, Marty saw Biff heading out of the garage to un-padlock the lock. Then Biff seemed to have forgotten something - probably his almanac - and he ran back into his house. As Biff went into the house, Marty sneaked into the back of Biff's car - and lay down low, to avoid being seen. The almanac was not to been seen in the car.
'Doc, it is Biff's house,' Marty told Doc, on the walkie-talkie 'I'm on him. Over.'
'Biff! Biff, where're you going now?' called an elderly lady's voice, possibly Grandma Tannen.
'I told you, Grandma,' Biff replied, huffily, 'I'm going to the dance!'
'When are you coming home?' asked Grandma Tannen.
'I'll get home when I get home!' Biff huffed.
'Don't forget to turn off the garage lights!' shouted Biff's grandmother.
Biff then stepped into the car, set his almanac on the dashboard, then drove off. He did not notice Marty in the back of the car.
'Doc, Doc,' whispered Marty, on the walkie-talkie, 'I'm in the back of Biff's car. He's on his way to the Enchantment Under The Sea Dance. When Jennifer and I parted ways, she headed off to the school.'
'I'm hiding in the ladies room,' called out Jennifer.
'The book is on Biff's dashboard,' continued Marty. 'I'll grab it as soon as we get to the school.'
'Marty! Jennifer!' called out Doc, 'You must be extremely careful not to run into your younger selves.'
'My younger self?' asked Marty, confused.
'Yes! Remember, your mother is at that exact same dance with you! Yeah!'
'Yeah, this could get heavy, Doc,' proclaimed Marty.
'Yeah, I totally concur,' added Jennifer.
'Whatever happens,' continued Doc, 'you must not let your younger selves see either of you. The consequences could be disastrous.'
'I don't doubt it, Doc,' Jennifer replied.
oooooooooo
'Excuse me, sir, called a familiar-sounding voice. Doc turned around, and noticed that it was his younger self from 1955. 'Yes, you with the hat.'
'Who me?' asked the elder Doc.
'Yes, be a pal and hand my five-eighths wrench out of that toolbox,' the younger Doc requested.
'Five-eighths?' asked the elder Doc, keeping his back to his younger self. 'Don't you mean three-quarters?'
'Why, you're right,' exclaimed the younger Doc.
'I presume you're conducting some sort of weather experiment,' asked the elder Doc.
'That's right,' replied the younger Doc, stunned. 'How did you know that?'
'Oh,' replied the elder Doc, 'I happen to have a little experience in this area.'
'Yes, well, I'm hoping to see some lightning tonight,' explained the younger Doc, 'although the weatherman says there is not going to be any rain.'
'There's going to be plenty of rain all right,' assured the elder Doc. 'Wind, thunder, lightning. It's going to be one hell of a storm.'
'Well, thanks,' replied the younger Doc. 'Nice talking to you. Maybe we'll bump into each other some time again in the future.'
'Or in the past,' mumbled the elder Doc, as he got onto his bike and drove away.
The younger Doc had then noticed a familiar ringing of bells, and he glanced around him a bit.
