A/N: Alright, this particular one-shot is set during the events of the BTTF game, episode 2: Get Tannen! For those of you who aren't familiar with it, it takes place in 1986. Doc has been missing for a few months, and the automatic retrieval system built into the DeLorean causes it to appear outside Doc's garage on May 14, 1986. Marty has to go back to 1931 to retrieve Doc, who was mistaken for an arsonist who blew up a speakeasy. Marty has to enlist the help of Teenage Doc, who has been working on a rocket-powered drill, which Marty needs to break 1986 Doc out of jail. But Young Doc has to deliver a subpoena to Marty's granddad, Arthur, calling him to court to give information about the illegal booze activities being performed by Kid Tannen, Biff's dad. The subpoena causes Arthur to be beaten up by Kid's gang and left for dead on the courthouse steps, and after saving him, Marty returns to 1986, only to find that the Tannens are the fifth most powerful crime family in California. When Marty returns home, the three Tannen brothers (Biff, Cliff and Riff) attempt to beat him up with baseball bats.

So this is a little what-if scenario which may have taken place if Marty hadn't used a bug-zapper to knock out the three Tannens.

Whew, that was a long author's note. Oh well, onward!

…

"Dad! Dad, it's me!" Marty called through the door. "Please, just open up!"

"If that's really you, Marty, tell me something only the real Marty would know!" George yelled back. Fear was clearly present in his voice.

"Umm… uhh… I've got a scar on my left knee!" Marty called.

"Oh yeah?" Lorraine said. "From what?"

"Skateboarding down the courthouse steps when I was twelve!"

"Oh my God…" Lorraine murmured. "It's him! George, let him in!"

Marty breathed a sigh of relief as he heard several locks being opened. The door to his family home swung open and he gasped. His father was in a wheelchair, looking badly hurt. His head was laid on one side, but he was grinning.

"Oh my God Dad!" Marty backed up a little bit. "What happened to you?!"

"The same thing that's about to happen to you, butthead!" A snarl from behind him made Marty whirl around. The front door of his home slammed shut and he was faced with a seething Biff Tannen.

"H-hey now," Marty put his hands in front of him, pressing his back against the wall. "I'm sure we can settle this…"

Two people stepped out from behind Biff's back and Marty gulped. They looked like Biff, but he wasn't sure. "Who are they?"

"Oh yeah, like you don't know Cliff and Riff," Biff scoffed. Marty held back a sigh. What was it with the Tannens and ridiculous names?

"Whoa, hey now fellas, I don't want any trouble…" Marty attempted to make a break for it, but Riff stood in front of him, blocking his way.

"Well, you've got trouble. We told you to stay outta Hill Valley!" He snapped.

Marty looked over the men's shoulders. "What the hell is that?!"

The three heads turned and Marty tried to run for it again. Cliff turned to him and stuck his foot out, causing Marty to trip and fall. As he scrambled to his feet, the group surrounded him.

"Nobody messes with the Tannen family!" Biff roared, bringing his baseball bat down hard on Marty's shoulder.

The teenager cried out in pain and he could have sworn he heard something snap. He stumbled to the side, only for Cliff to smash his golf club into Marty's ribs. That knocked the wind out of him and he fell to his knees. Riff kicked Marty in the face, sending the teenager flying backwards into the wall. The trio of troublemaking Tannens continued to beat him, causing Marty to curl up into a ball, wrapping his arms around his head in a futile attempt to protect himself.

The weapons came down hard on his small body. They struck him with enough force to break his bones in a single hit, without sustaining any damage themselves. He cried out as he was struck multiple times, especially on his sides and back. He kept hearing the sickening crack of bones shattering, and he just hoped that this would all be over soon. Tears streamed from his eyes, caused by the pain he was in.

"Pathetic!" Biff spat on the ground next to him. "Just like all McFlys ever were!"

His two brothers laughed obnoxiously in agreement and continued to bring the weapons down upon him. They seemed to find enjoyment from watching Marty in pain and got even more enjoyment from being the ones inflicting the pain. He was their chew-toy, and they were slowly beating him to a pulp.

While this was going on, Kid got out of the black limousine parked on the McFly driveway and walked up to the front door. He appeared not to care about the beating going on beside him as he strode forwards and knocked on the door.

"Please! Don't hurt Marty anymore! We've got the money right here!" George's trembling voice called as he pulled the door open, quickly shoving a briefcase at the man. "Now leave him alone!"

Kid opened the case, smirking as he noticed it was full of dollar bills. He sneered at the family, before walking away without so much as a "thank you". He heard the door slam shut behind him and he looked over to his sons.

"Boys! We've got what we came for, we can leave," he said, and like obedient dogs, the three Tannen brothers left Marty on the ground and walked back over to the limo, their various weapons resting on their shoulders. They got back into the limo and left.

Marty couldn't breathe. He attempted to lift his head up and almost gagged at the sight of the blood - his blood - on the ground. The red liquid was running steadily down his face and across the corner of his mouth. Every bone in his body felt as though it was broken. He reached forward weakly with one arm, wincing and trying not to scream. He was dizzy and in pain. His parents didn't come out to see him - they were petrified that the Tannens might come back and finish the job. They didn't call an ambulance either - by doing that, the police would find out what had happened and they'd be in for it.

Marty lifted his head up again to see the DeLorean come to a stop by his driveway. Doc must have spotted him as he immediately got out and rushed over, paying no mind to the fact that the keys were still in the car. He knelt down beside Marty and lifted the broken teen up to lean him against him, keeping his arms around him protectively.

The teenager coughed weakly but looked up at the scientist. In his dazed state, he could barely make out the features in Doc's face. "D-Doc…?"

"Great Scott, Marty! What happened?!" The scientist exclaimed, wiping some of the blood from Marty's head.

"T-Tannens," Marty coughed hard, and by the sound of it, Doc could hear that there were several broken ribs pushing against his lungs.

Doc carefully shifted Marty fully into his arms and lifted him up, apologizing when the teen cried out in agony. "Sorry, but we've got to get you to a hospital,"

Marty nodded weakly, too tired and in pain to care at this point. He felt his vision going dark and his eyes began to droop shut. His whole body felt like it was made of lead.

Doc shook him gently. "No, no Marty! Stay with me, look at me kiddo,"

"Tired…" Marty mumbled, beginning to pass out.

Doc shook him again. "No, you have to stay awake, please!" He carefully laid Marty down on the passenger's seat of the car, getting in the driver's side and pulling the door shut. He slammed his foot down on the accelerator and sped off down the road. "Just keep talking to me Marty!"

"Th-they… hurt my d-dad…" Marty murmured weakly, wincing every now and then as the DeLorean drove over a bump in the road. "He w-was in a … wheelch-chair…"

"As soon as you're better, we can fix this mess," Doc assured, reaching across and squeezing the teenager's hand. "Just hang in there,"

Marty's vision was going dark again. "It hurts…"

"I know it does, but just stay awake!" Doc shook his shoulder again, trying to keep the teenager from passing out. "Come on, stay with me!"

"Tryin'..." Marty shifted ever so slightly and let out a sharp cry, his face twisted in pain. "Augh!"

"Don't move," Doc said as he kept driving. "Don't move, you'll hurt yourself more,"

Marty nodded weakly and instead kept his gaze fixed firmly on the road in front of him. The dashes of paint on the asphalt made his head spin and his eyes drifted shut.

Doc began to panic even more and shook his head, tapping his hand against the side of Marty's face a couple of times. "No no no don't close your eyes. Just look at me, alright. Look at me."

Marty turned his head to the left and tried to keep his gaze on the scientist next to him. "'kay…"

"That's it! You're doing so well! Just keep looking at me, okay? We're nearly there!" Doc encouraged as he rounded the corner and skidded to a halt in the hospital parking lot. He rushed out, grabbing the keys, shutting the door and running around to the passenger's side. He yanked the door open and lifted Marty into his arms. The teenager let out a yell again as Doc kicked the door shut and locked the car.

"Sorry, kiddo, just hang in there!" Doc carefully rushed towards the main entrance. A few screams came from various visitors as he burst in through the doors. Nurses and doctors immediately rushed over and Marty was taken from him. The teenager was laid down on a bed and wheeled swiftly down the hall.

Taking a few deep breaths, Doc decided he had no choice but to just sit down and wait for news on his friend's condition. He decided that it was best he didn't contact anyone, just in case it had any effect on this timeline. He received a few odd looks from other people as he sat there. He had just burst through the front doors, carrying a horrifically wounded teenager, after all. His hair was sticking up in all directions and he cringed as he looked down at his coat, noticing traces of blood upon it. He quickly took it off and went outside to put it in the DeLorean.

The car had also received some odd looks. People noticed just who the car belonged too and decided to ask no more questions. He sat down on the driver's seat of the car and laid back, trying to contemplate what had just happened. Obviously, something they'd done in 1931 had affected 1985 and produced this timeline. Marty had told him that the Tannens were involved somewhere, so maybe this had something to do with Kid Tannen. As he thought about it, Doc realised that Kid had never been put behind bars like he was supposed to. That would have led to him being able to raise more Tannens and causing the family to become California's fifth most dangerous crime family. While that didn't seem like much of an achievement, it was obviously enough to shatter their timeline - and Marty's life.

Doc shuddered a little as he thought about what the McFlys must have gone through. Up until the point of their return, the Marty from this timeline must have seen some pretty harrowing things. His father had been injured badly enough to be put in a wheelchair and clearly the Tannens had some sort of grudge against the teenager too. From what he'd managed to dig up from old newspapers, Marty had been run out of Hill Valley back at the end of 1983. That's why he decided to go back to the McFly family home, in case Marty ran into any trouble. It was a good thing he did, too. He shuddered to think how long Marty would have been laying there if he hadn't turned up.

After quite a while, Doc got out the car and headed back to the hospital, sitting down in the waiting room. He flattened his hair down and tried to calm his nerves. Holding a hand out in front of him, he noticed he was shaking. He took a deep breath and folded his hands in his lap, waiting for one of the doctors to come out and tell him how Marty was doing. In the meantime, he cast his eyes around the waiting room. Only a few other people were there; a few young kids, a woman talking on the phone and someone reading a newspaper. The waiting room itself was a faded off-white colour; several patches of the paint were peeling off, the carpet was faded and a few small marks were on one wall, possibly from someone kicking a ball against it at some point. Deciding not to be nosy, Doc settled back in the chair and tried to relax.

It seemed like days before a doctor finally came over to him. "Doctor Brown?"

Doc immediately looked up. "Yes? How is he?"

"Well… come with me, I'll explain," The doctor gestured for Doc to follow him. The pair walked down the hall and into a separate room. Once the doctor closed the door, he turned to face Doc. "He has eight shattered ribs, a severe concussion and one of his legs is badly bruised. His left arm has a hairline fracture. It seems as though he was hit mostly on his abdomen and head, and tried to shield himself with his arms. We're not sure how long it will take for him to recover."

The doctor showed Doc some x-rays that had been taken. He pointed out the teen's broken ribs, although he didn't need to. They were as clear as day, indicating that they must have been hit pretty hard in order to be broken like that. Doc cringed. "When will I be able to see him?"

"Right away, although," the doctor lowered his voice. "Everyone in Hill Valley knows what happened to him two years ago. You do realise that if the Tannens find out about this, it'll mean trouble."

"I'm willing to make that risk," Doc replied, getting to his feet. "Where is he?"

The doctor frowned a little and showed Doc up a flight of stairs and into a ward. "He's in room five," the doctor said as he headed swiftly out of the double doors. Doc took a deep breath and walked down the hallway towards room five. Grasping the handle, he pushed the door open.

Marty was lying fast asleep in the single bed in the room, looking pale and fragile. Both of his arms were laid over the covers, one wrapped in bandages, the other with an IV in it. The thin tube led from his arm and up to a bag with a clear liquid in it. An oxygen mask covered his face and his snores were muffled slightly. A nasty scrape was visible on his head, just below the bandages and his arms were covered in dark purple-black bruises. He had a black eye and his face had a few smaller bruises on it too.

Doc sighed and took a seat next to Marty's bed, his head in his hands. The shock still coursed through his body, making him feel disorientated and dizzy. This couldn't be happening, could it? No, this was all a dream. Just a very intense dream, that's all. He'd wake up any minute now, next to Clara, and Marty would be safe and sound at home. The teen would probably come over that day to work on something, or even just to say hi. No matter what he did, he wouldn't be lying badly injured in a hospital bed.

Oh, who was he kidding? This was all real, every bit of it. This meant that they would have to go back to 1931 and make sure Kid Tannen was arrested, otherwise, this future would stay reality. He was grimly reminded of the "1985A" scenario a little while ago where Marty's almanac had fallen into Biff's hands, allowing him to win at any and every bet he placed. The sheer amount of power Biff had was enough to remind them that letting the Tannens have the upper hand at any given moment was a mistake. They would have to go back and make sure Kid got arrested. That way, he wouldn't be around to cause any problems for anyone in Hill Valley.

After, of course, Marty woke up.

The scientist looked at the teenager again. Marty was frowning and murmuring something in his sleep, clearly distressed. Doc's eyebrows creased and he shook Marty's shoulder gently. "Marty? Come on, wake up,"

Marty frowned and shook his head a little. "Mom… I don't wanna go to school…" he murmured quietly, causing Doc to chuckle.

"No, Marty, it's me. Come on, open your eyes,"

Marty groaned a little and his eyes fluttered open. "Doc…? That you…?"

"Yes, I'm right here," Doc squeezed his uninjured hand. "How do you feel…?"

"Sick… like really freaking sick…" Marty muttered. "My head's spinning and I feel like shit,"

Doc rubbed his thumb across Marty's hand. "You'll feel better soon. As soon as we get back to 1931, none of this will ever have happened,"

Marty nodded a bit, then instantly regretted it as another wave of dizziness swept over him. "Urgh…"

Doc sighed. "Thank God I found you when I did,"

Marty nodded slightly in agreement. "Yeah, who knows how long I would have been lying there. I might've died,"

The scientist shuddered a little bit. "Please don't think like that,"

Marty frowned. "Sorry…"

Doc shook his head. "Just try and get some rest. As soon as you're able to walk again we're going back to 1931 and fixing this mess,"

Marty gulped. "But what if the Tannens figure out that I'm here and come back to finish the job?"

"They'll have to get through me first," Doc winked and showed the teenager a small pistol he had hidden on the inside of his jacket pocket.

The teenager's eyes widened a little. "You wouldn't actually shoot anyone, would you?!"

"I'll try not to, only if it's absolutely necessary," Doc replied. "Now just try and get some sleep,"

Marty nodded and settled back into the pillows, shutting his eyes. Doc let go of his hand and got up, heading towards the door. He had to make sure that the Tannens weren't coming anywhere near them. He checked both sides of the hallway and, satisfied that they were clear, took a seat on the windowsill by Marty's bed. Rain was starting to fall, hitting the glass and trailing down, the drops merging the further down they got. Small pools collected on the ridge of the window before falling down. Somewhere in the distance, thunder echoed and lightning flashed. Doc pulled the curtains shut and sat on the floor, resting against the wall.

A nurse knocked on the door quietly a few moments later. "Sir?"

Doc got to his feet. "Yes? Come in,"

The door was pushed open, revealing a nurse in her thirties, with brown, wavy hair. "Mr McFly needs to wake up, I need to check on him,"

Doc nodded and shook the teenager's shoulder gently. "Marty? C'mon, you need to wake up,"

Marty groaned and pulled his eyes open. "Oh, what now? I was just drifting off,"

"I know, but I need to check on your vitals," The nurse replied. She looped a band around Marty's arm and pressed a button on the machine. It tightened, before loosening gently. She also checked his temperature. Once she was finished, she seemed satisfied that he was alright. "Everything is normal, I'll take this IV out but the cannula will have to stay in just in case you need something else later,"

Marty nodded. "'kay." The nurse carefully removed the IV and took the empty bag away. She gave the teen one last check over before heading out again.

Marty groaned and settled back into the covers. "Can I get some sleep now?"

Doc chuckled. "Yeah, go on."

Marty sighed and closed his eyes again, starting to drift off. Doc gave his hand a squeeze before settling back in the chair. It had been a long day. They'd spent the better part of the day in 1931 trying to deliver the subpoena and then Marty had returned home, only to be beaten up by the Tannens and hospitalised. Doc thought that it would be best if he stayed awake to make sure nobody turned up in the middle of the night, but his exhaustion soon caused him to pass out too.

….

Doc woke to the sound of someone yelling. His eyes snapped open and he was met with the bright-red, angry face of Biff Tannen. His two brothers were standing either side of Marty's bed. The scientist scolded himself for falling asleep. How could he have done this?!

"What on Earth do you think you're doing?!" Biff snapped. "Bringing that little shit here!"

Doc stood to his full height of six-foot-one, a harsh glare on his face. "Saving his life, the life you nearly took from him," He replied. "Now, kindly get out,"

Biff snarled vituperatively. "Oh no, that ain't happening until that kid is six feet under!"

Doc was quick as a flash as he whipped the pistol from his pocket, pressing it to Biff's forehead. "Get out. Now."

Biff snarled and his two brothers were at his side immediately, weapons of their own drawn. Marty was sat bolt upright in bed, petrified. The three Tannens each held their weapons against the scientist's head. "Go ahead," Cliff sneered. "Just shoot,"

Doc froze. No matter who he shot, there would still be two Tannens left to pull the trigger on his own head. Then Marty would have no-one. He gulped.

Biff sneered. "Well, you're outnumbered."

Doc's glance shifted quickly to the teenager, who was watching the scene unfold in front of him in horror. Biff noticed his gaze and looked behind him at Marty. He laughed. "Don't worry, that kid's getting what's coming to him,"

The three Tannens advanced on Doc, pushing him further against the wall. At the moment, they all had their backs to Marty. The teenager made a split-second decision. He carefully got out of the bed, trying to hold back a wince as he put pressure on his injured leg. He winked at Doc and the scientist continued to focus his attention on the Tannens as to not draw attention to Marty. Marty grabbed the nearby IV stand and picked it up. Taking a deep breath, he swung it at the Tannen's head. Cliff was knocked clean out, plaster exploded from the wall from a gunshot and amidst the confusion, Doc slammed the handle of the pistol down on Biff's head while Marty hit Riff on the head with the IV stand. The three Tannens slid to the floor, clean out of it.

Several nurses had rushed into the room to see what all the commotion was about. In the centre of the room stood Doc holding a pistol, Marty in his hospital gown still clutching the IV stand and three unconscious men lying on the floor. The nurses gasped a little and exchanged looks between themselves.

Only now did Doc notice what Marty had done. "Great Scott… good thinking Marty!"

Marty grinned a little and set the IV stand back down, only to let out a sharp cry and clutch his side. Doc put the pistol back in his pocket and rushed over, helping Marty back into the bed. The nurses took the three unconscious Tannens from the room and left to call the police. Doc pulled the blanket back up over the teenager as Marty laid down again, still gritting his teeth.

"As grateful as I am for you doing that," said the scientist. "You shouldn't have gotten out of bed. You're still injured."

"I know," Marty replied. "But they were gonna shoot you. I couldn't just sit there and do nothing, could I?"

Doc sighed and sat on the edge of his bed. "I suppose not, but even so, you should not have risked your own health in order to help me,"

Marty shook his head. "I'd never forgive myself if I just sat there and watched you get killed,"

Doc squeezed his shoulder. "Well at least now you can get some decent rest,"

Marty yawned and nodded a bit, relaxing into the pillow and shutting his eyes. "'Night,"

"Goodnight," Doc got up from the side of the bed and took a seat in the chair as Marty drifted off. He too laid back and it wasn't long before he fell asleep.

…..

Forty hours later, Marty was able to be released from the hospital, being given strict instructions to take it easy. However, both he and Doc knew that the chances of that happening were very slim. They still had to make sure that Kid Tannen was arrested back in 1931, after all. As soon as Marty left the hospital, Doc was waiting outside with the DeLorean. He honked the horn a couple of times. "Come on Marty!"

Marty walked over, still being mindful of his injuries. He pulled the passenger door open and got inside. "Let's go and make sure this never happens,"

Doc nodded and with a grin, put his foot on the accelerator. The car pulled out of the parking lot and onto the open road. Marty entered the necessary information and Doc sped up. Once the car hit eighty-eight miles per hour, it disappeared in a flash of blue and the pair went back to 1931 in order to fix their future...
