Well….here it is…I present to you, the last chapter of Heavy Stuff. I hope you enjoy! :D xxx

The weary travellers walked along the road that they knew so well. Marty and Doc had walked up and down it countless times in the future, when both fields and buildings lined its edges. Now as the night time darkness settled in for the evening, the two men were approaching their days end. When Marty had arrived from 1985, he had made sure to park the DeLorean in its usual place. Over the years, Marty had come to see this spot as a temporal car parking space. 'Time machines only.'

They reached the DeLorean, Doc patting the stainless steel surface as if it were Einstein or Copernicus. A smile dancing across his face.

'There she is. Safe and sound. Ha. Back there in my cell, I didn't think I'd ever see her again. Or you for a matter of fact.' Marty watched as Doc walked around the car, checking that there hadn't been any accidents on arrival. 'My message on the recall device did remind you to bring extra plutonium, didn't it? The Mr Fusion energy converter has developed some teething problems. Keeps jumping time tracks. I was supposed to arrive in April 1932.' Marty nodded, thinking back to what seemed like years ago, but in actuality had only been this morning.

'Yeah, I followed the instructions to…'Marty had to stop and smile before he spoke. He knew that this was one of the sentences he never thought he'd say. '…your plutonium stores in the basement.'

'Ah good. Good. We can leave then.' Doc gesticulated as he reached the front of the DeLorean. 'Don't suppose you can drive us back. You have the key and the events of this evening are starting to catch up with me. It's been a long day.'

'You're telling me.' Marty remarked. Doc walked around to the right side of the car, pulled up one of the gull-wing doors and slipped into his seat. Exhausted. Marty rummaged around in the pockets of his suit and found the keys languishing in the bottom inside inlet. He wasn't used to all these places to conceal items. He walked around to the other side of the car, opened the door and slumped into the driver's seat. Pure comfort. He then placed the key into the ignition and was about to start her up, but there was something else. Marty had a few questions for Doc.

'Doc, can I ask you something?' Marty could see Doc nod as he started to fasten his seatbelt. 'What were you doing back in 1931 in the first place?' The question seemed to linger in the air; unanswered. Doc looked him straight in the eye, knowing that the truth would have had to come out eventually. Doc knew he couldn't lie to Marty.

'Those gang planks on the clock tower aren't just for the builders to erect those statues, you know?' Doc started to rummage around in the inside pocket of his jacket. After bringing out a watch with strange symbols instead of numbers, a bundle of string and a screwdriver, Doc seemed to have found what he was looking for. His notebook. The thing was massive. Wedged shut by a rubber band, paper practically bulging out of the sides. All with Doc's little notes and ideas scribbled onto every side. After Doc had replaced the clock, the string and the screwdriver, he removed the elastic band and started to rifle through the notebook. Marty eagerly watched as his mentor flicked through to the middle pages. He brought out a wedge of paper, before handing the notebook itself to Marty. 'Could you keep a hold of that for a moment?' Doc began rustling through the pile of paper until he found two photographs. He handed the rest of the paper to Marty, who placed the remaining sheets back inside the notebook. Doc then turned the photos so that Marty could see them. The first image was of the clock tower. Marty couldn't tell when the image was from, but the statues were there and the gangplanks were gone. Some time after 1931 then.

'Look at the photo. What do you see that's strange about it?' Marty glanced over it. There was no point scanning it if Doc was going to tell him anyway.

' I don't see anything strange or out of place…'

'What about this?' Doc pointed to a small square smudge in the bottom right hand corner of the image. Marty leaned in closer and indeed could not remember it being there before.

'Yeah. What is it, Doc?' Wordlessly, Doc flicked the front image to the back and replaced it with the other photo. It was a zoomed in image of the small smudge. Here the lines were more defined. To Marty, it looked like a plaque that you'd find outside an office door. Like Judge Brown's.

'Read it.' As Marty took both of the photos into his hands to view them under a better light, he read out the words of the enhanced image:

In loving memory of Marty

Marty's eyes widened as he re-read the words on the photo.

'Geez, Doc. Is that about me?'

'That's the hunch I was following. I found it in my visit down to the library. I was planning a trip to a different time period for Clara's birthday. Somewhere in her future, but my past. I wanted to choose somewhen nice. I was just flicking through the papers from 1931, my childhood just seemed appealing, everybody remembers being that age, and I saw this picture. But, like you, I didn't remember seeing that smudge. So I found another image and enhanced that.' Marty couldn't believe it. It had to be a fake. A fabrication. 'I thought 'Great Scott, what if that's my Marty?' So I checked through the records for anybody called Marty who had lived and died in Hill Valley. And you know what? There aren't any until you're born in 1968, and I have a sneaking suspicion that your name is a result of our trip back to 1955. And I couldn't find any paperwork regarding the production of the plaque in 1931. So much bureaucracy in the way they could barely tie their shoelaces. I came back in time to 1931 to see if this was you. I started asking around and was on my way to my Pop's office for some information, he always worked late, when the speakeasy burnt down and I was arrested.' Doc's story didn't seem real. Marty wanted to question it further, but his voice betrayed him. After a few seconds, he found it again and wanted to dig deeper. He was still looking at the photo as if it were a fake. It just wasn't possible.

'When is this photo from?'

'Well, the plaque isn't in any photos from 1931, so I looked at 1932 and all of a sudden, midway through the year, there it is. I must have skipped into the 1932 papers by accident.'

'Does it give a date?'

'Sadly not. There are no reports about the death of a 'Marty' in Hill Valley either. It just appears.'

'So I die somewhere between late 1931 and early 1932, but we don't know when. You said you wanted to arrive in April 1932…'

'But the converter for Mr Fusion was bust…yeah. The plaque appeared in May and I thought April was a good place to start.'

'Well, come on. Let's go. We have to find out if it is me, and how, and why? And…'

'Marty, calm down.' Doc placed his left hand reassuringly on Marty's shoulder, 'I know it's a shock, but we have to stay calm. I know how you feel. I've been through this too remember. Keeping our heads is the only way that we're going to overcome this. Now if we go back to 1985, we can see if the photo is still like that. Maybe you were supposed to die here in the firing line or the fire itself. Maybe bureaucracy got in the way and that's why it took so long for the plaque to be installed. There wouldn't be any other reason to come back to 1931 but for me. Maybe history has been rewritten. If so, all will be back to normal when we return to 1985.' Doc stated. Marty nodded, shaking slightly at the thought that he might have died today. He knew he hadn't, but the thought was still unbelievably overwhelming. That worry of dying where nobody would be able to grieve his loss was still as potent as anything in Marty's mind. Without hesitation, Marty began to set the time circuits to a few hours after he had left in November 1985.

'Right, ready to go?' Marty called, trying to stay calm, his mind set on the task at hand. But he did not receive a reply. After a few moments, Marty enquired, 'Doc? Are you alright, Doc?' Doc was staring down towards his feet. He lifted his head and looked sincerely at Marty. He then raised his left arm, only for both of the men to see his hand slowly fading. All of a sudden, the whole of Doc started to shimmer out of existence.

'I'm sorry, Marty.' Then Doc started to flicker and became far less defined, like a ghost. Marty's mentor looked at him as though seeking acceptance. And then, faster than a blink of an eye, Doc disappeared.

'NO DOC!' Marty shouted at emptiness. Doc was gone. 'No. I've got to get back. Got to find you.' The events of the last few hours had caught up with them and now Marty was left alone. What could have changed so much that Doc disappeared completely and so suddenly? It was all Marty's fault. Whatever had happened. And Marty had to fix it…

With a determined mood washing over his tired, confused and shaken form, Marty pulled the DeLorean from its temporal parking space and on to the main road. Staring into the darkness of the night, he started the time machine's engine and began to build up speed. He could feel the revs as they built up under his feet. Like a cantering horse awaiting the order to gallop. Finally, Marty released the pedal and the DeLorean zoomed into the darkness.

Fifty eight miles per hour….the speed was building up and Marty could feel the power channelling through his determination. His need to know what happened rising.

Sixty eight….There it was, that roar that only the engine of a DeLorean could release.

Seventy eight…Building and building. The energy of nuclear fusion generator building, ready to be unleashed upon the world.

EIGHTY EIGHT MILES PER HOUR!

Light enveloped the car and its passenger. Tracks of burning fire marked the DeLorean's course as it made its way through the treacherous minefield that time travel set out for her. BOOM!

And the car vanished. All that displayed that anything had even been there that night were flaming tyre tracks. Burning their way through time….leaving their mark….and leading anywhere.
