The next day, Marty and Jennifer were helping Doc fix the DeLorean. Doc was working on the tires - and they were communicating with Marty and Jennifer through the walkie-talkies.
'Doc, Doc,' called out Marty, 'this is Marty. Can you read me? Over.'
'Check, Marty,' replied Doc
'Great, Doc,' Marty said, with relief, 'these things still work.'
'All right,' Doc said, as he put the walkie-talkie down.
Doc, Marty, and Jennifer then moved towards a model railroad that Doc has built. There was a train, various named locations, and a small model DeLorean marked 'Time Machine'.
'Marty and Jennifer, once more,' Doc explained, 'let's go over the entire plan and layout. I apologise for the crudity of this model...'
'Yeah, I know, Doc,' Marty cut in, as he remembered the conversation they had with Doc in 1955 in Doc's lab, when Doc showed them the model of the town square. 'It's not to scale. It's okay, Doc.'
'All right,' Doc replied. 'Tomorrow night, Sunday, we'll load the DeLorean on to the tracks here on the spur - right by the old abandoned silver mine. The switch track is where the spur runs off the main line three miles into Clayton...' Then, correcting himself, he said, 'Shonash Ravine. The train leaves the station at 8:00 Monday morning. We'll stop it here, uncouple the cars from the tender, throw the switch-track, and hijack...' He smirked, as he once again 'corrected' himself, 'borrow the locomotive and use it to push the time machine. According to my calculations we'll hit 88 miles per hour just before we hit the edge of the ravine, at which point we'll instantaneously arrive in 1985 and coast safely across the completed bridge.'
Marty then spotted a sign near the model windmill. It said 'Point Of No Return'.
'What does this mean?' Marty asked, confused. 'Point of no return?'
'That's our failsafe point,' Doc explained. 'Up until that point we can stop the locomotive before it plunges over the ravine. But once we pass that windmill, it's the future or bust.'
A few minutes later, Doc was sorting out the electricity to work the model.
'Here you go, Marty,' Doc said. 'Connect that to the positive terminal. All right, Marty, you all set?'
'Yeah, yeah, go,' repled Marty.
'Train pulling out of the station!' Doc said, as he pushed the switch down more to get the train's speed up. 'Coming up the switch track! Stop at switch track! Throw switch! Pull up the DeLorean! Pushing the DeLorean up to 88 miles per hour!'
As the model DeLorean and train fell off the table once they hit the 'ravine', the car was caught by Doc, while the train landed onto a pillow placed underneath.
'It couldn't be simpler!' proclaimed Doc.
Just then, there was a knock on the door.
'Hello?' called out a feminine voice. 'Mr. Brown? Are you in there?'
Doc quickly glanced out the door to see who it was, and she said, 'It's Clara! Quick, cover the DeLorean.'
Marty and Jennifer helped Doc cover the DeLorean with a sheet - and, as Clara let herself in, Marty hid the model DeLorean.
'Hello!' called out Clara, as she walked in. As she and Jennifer glanced at each other, they were stunned. They really did look identical!
'Why, hello,' Jennifer said, stunned by her 'twin'. 'This is quite a surprise. So what brings you over here?'
'Well, I hope I'm not disturbing anything,' Clara said, also stunned. 'You really do look like me!'
'Oh, no,' replied Doc, 'we were just doing a little model railroad.'
'Well, anyway,' Clara said, 'I was wondering if you people were planning on attending the town festival tonight. It is a very important event, and Mark and Jamie will be there. They're going to be putting up the clock tonight.'
'Yeah, I wanna go,' replied Jennifer. 'It sounds like fun.'
'Oh, I'm sure it will be a lot of fun,' Clara said, smiling at Jennifer.
'Yeah, Doc,' added Marty, 'can Jennifer and I attend the festival?'
Doc was silent for a moment, then she said, 'I guess you two can go.'
'So is that the only reason you came over here?' asked Marty. 'Just to ask us if we were going to the festival?'
'Well, actually, I wanted to get to know you a little better,' Clara said, turning to Jennifer. 'I was wondering if we might be related. We look so much alike, after all.' Then, turning back to Marty, Clara added, 'You look real familiar to me, too.'
'Oh, really?' Marty asked, stunned. 'Well, I guess I do kinda look like Seamus.'
'No, not Seamus,' Clara said, shaking her head. 'Actually, you look like his little brother, Martin. My big sister used to court him.' Clara then looked a little sad.
'Ah, yes,' Doc said, nodding. 'Your brother and Seamus told me all about Martin and Juniper.'
'What happened to Martin and Juniper?' Marty asked, with curiosity. Then, forgetting the Clara was in the room, Marty added, 'You mean our paths have crossed before?'
'What are you talking about, Mr. Eastwood?' Clara asked, confused.
'Please, call me Marty,' Marty said, smiling. 'I guess what I was saying was, Jennifer and I may be distantly related to Martin and Juniper.'
'Gee, if I didn't know any better,' Clara said, sighing, 'I would almost think you two are Martin and Juniper come back from the dead. Juniper is my older sister.'
'Wait a minute!' exclaimed Marty. 'Martin and Juniper died?'
'Yeah, sadly, they did,' Clara said, as she was trying hard not to cry. 'Martin was stabbed in the belly with a bowie knife, and my sister committed suicide not long afterward. The whole town was grief-strucken. Most of the girls in town thought that Martin was the most handsome guy around.'
'That sounds so sad, Clara,' Marty said, as he was blinking back tears.
'So how old are you, Clara?' asked Jennifer.
'I'm seventeen years old,' replied Clara. 'My birthday is on the fourth of April.'
Jennifer quickly calculated, and she realized that she and Clara were roughly the same age. 'Wow!' gasped Jennifer. 'We are the same age!'
'Juniper was seventeen when she committed suicide,' Clara said, sadly. 'That was five years ago. I was only twelve then.'
'So what brings you to Hill Valley, anyway?' asked Marty.
'Well, I came here from Virginia City, Nevada,' explained Clara. 'My ma died when I was a baby, so it was just Pa, Mark, Juniper, and myself. Pa died a few weeks ago, though - and I knew Mark was living here with his wife, Jamie.'
'Ah, I see,' said Jennifer, stunned. 'Well, it's been a real pleasure meeting you.'
'Yeah, it's been nice meeting you, too,' replied Clara. 'I'd better get going, now. I'll see you tonight.'
Clara and Jennifer then embraced, before Clara left.
