A/N: I really went with the idea that when a werewolf transforms without Wolfsbane he completely looses him/herself. That is the reason that Greyback doesn't use names when he's thinking to himself. Anyway...enjoy...I hope.

PAST

Harry could only stare as Greyback made his way closer to him, his eyes holding a triumphant gleam.

Suddenly a flash of light brown streaked past him. His eyes widened as Remus grabbed hold of Greyback around the neck and pulled him off to one side.

Harry let out a slow long relaxing breath. Remus was now stood between him and Greyback, panting heavily. Greyback had picked himself up and was now making his way towards the pair, eyes gleaming malevolently.

Remus growled as Greyback neared, his hackles raising.

Harry watched as the two werewolves sized each other up. He hoped to God that Remus had enough strength to hold him off.

Greyback was working on instinct alone, it was in a werewolf's nature. Remus, however, still had his own mind and a fierce desire to protect Harry, not just for him but for Lily and James.

The battle began and for a while the only movement was Greyback lunging forwards towards Harry, and Remus jumping in between them and throwing him off. Harry was sure that this could be quite easy if it carried on like this.

Having being pushed back once again Greyback paced a while. This was going to be difficult, whoever that werewolf was he wasn't going to let him eat the human he was guarding.

He snorted and faced the werewolf and human, his mind working in overdrive.

In order to kill the human I need to get rid of the other werewolf.

Greyback crouched low ready to pounce again, Lupin growled at him again and readied himself. He watched as Greyback pounced and veered off to the side, to his tail.

Thinking quickly Remus spun round to protect his tail and felt his throat come into contact with Greyback's mouth. He choked slightly, Greyback didn't have a proper hold but it was enough to disable him if he didn't get him off now.

Remus rolled over on to his back and kicked out with his back legs powerfully. A small yelp and a sudden release on his throat told him he'd thrown Greyback off, and he rolled back picking himself up slowly.

He glanced back at Harry, he was still ok... better than me anyway he thought as he watched droplets of red fall to the floor. His neck was bleeding heavily and he more than likely would be feeling the effects soon.

Greyback got up abruptly ready to pounce again. He wanted this meal desperately, and nobody was going to stand in the way.

This werewolf is injured now, he thought as he watched Lupin take in a few shaky breaths. He held back eyeing him menacingly, looking Remus over quickly.

Greyback dove once again veering off course. Remus was caught momentarily unawares, but a moment was all that Greyback needed. He sunk his teeth deep into Lupin's left thigh, one of his teeth connected with the bone and he heard a satisfying crack.

Remus scrunched his eyes up tightly trying not to cry out, doing so would alarm Harry. After a few painful seconds he couldn't hold it in any longer and let out a blood curdling howl, Greyback held on tightly.

Harry was frozen with fright and was only brought back to reality when he heard Remus' anguished howl. He shook his head and took in the scene in front of him.

Remus was desperately trying to shake Greyback off his leg without avail. Thinking quickly Harry kicked out towards Greyback. His foot connected solidly with Greyback's nose and he let go yelping in pain.

Remus glanced up at Harry, gratefulness apparent in his amber eyes. Harry smiled at him and moved across the room, distancing himself from Greyback who was shaking his head from a sitting position across the room. Remus followed limping painfully in front of Harry.

Remus' breathing came in painful rasps, he had two injuries now that were bleeding badly. He wasn't doing too well as protector at the moment. He closed his eyes briefly trying to clear his blurring vision, he needed to get Greyback down soon if he was going to help Harry at all.

Greyback opened his eyes and was greeted with a wonderful sight. Remus was standing up, his injured leg very open and vulnerable and he had his eyes closed. He attacked again and grabbed hold of the same injured leg around the knee.

Remus' eyes snapped open and he bit down hard as he held in the howl trying to break free. That had been unexpected and had happened way too quickly.

He felt himself sink to floor desperately trying to remain conscious. Greyback sensing this defeated posture growled furiously, he wasn't ready for this to finish. With an almighty heave he threw Remus bodily over his shoulder.

Remus hit the ground heavily and heard his ribs crack agonizingly. He produced a feeble growl from his mouth, but before he could do anything else Greyback was on him again.

Remus just lay their feeling quite defeated as Greyback took angry swipes at his back. He felt each and every one wondering when it was going to stop.

"No,"he heard a voice thunder from the far end of the room. His ears pricked up and he lifted his head wearily.

Harry was stood in a very similar way to how James had done. His right hand raised palm facing outwards. His eyes flashing fiercely.

"Impedimenta!" he yelled.

Greyback looked up just in time to see a bright red light head straight for him. Greyback was blown backwards into the wall, unconscious for the moment.

Remus pushed himself up regardless of his body's protests. He limped slowly over to Harry and lay down watching Greyback's limp form.

Harry sunk down beside his Professor and friend, his breath hitching in his throat.

There was so much blood, and the cuts looked so deep. He reached out to stroke an uninjured piece of Remus' back and felt Remus flinch slightly before relaxing again and grumbling in the back of his throat.

PRESENT

Remus was watching out of window that the Room of Requirement had provided. He couldnt sleep, the memories that were flashing before his eyes were too terrible. He could only sit and watch as Greyback lunged towards him and Harry again and again and again.

He gasped as he felt pain in his leg and he pulled his boxer shorts down slightly to find the source.

The skin at the top of his thigh was bright red, his eyes widened. The skin opened up slightly and let out a small trickle of blood, Remus bit his lip. What was going on? As quickly as the bleeding started it stopped and a large white scar was left in it's place. Remus frowned, a new scar?

Over the next five minutes Remus watched a new scar form on his knee, and he even pulled his shirt off to watch several scars criss cross their way across his back. He touched his neck where a scar had appeared he had not noticed before as well.

He closed his eyes trying to think of when he had fought with Greyback, all of a sudden it became clear. He sighed hopelessly, as long as he was alive in the future he must be doing fine in the past.

PAST

"Stop that,"

Remus heard Harry mutter in an annoyed tone. His ears pricked up and he turned his head slightly to face Harry.

Remus had been willing the night away, as long as Greyback didn't get up again Harry would be fine. Maybe not him but Harry would be.

Harry's eyes were flashing fiercely with anger first and foremost but as Remus looked deeper... was that fear? Yes he was sure Harry was angry and afraid.

"I said stop that," demanded Harry again more firmly this time. Remus stared up at him.

He couldn't talk so this was going to be a very one-sided conversation. He creased his forehead slightly trying to get Harry to elaborate a bit more.

"You know what," Harry whispered quietly continuing his light stroking on Remus' back. Remus eyes widened... success! Harry had understood. Remus frowned to himself... but he didn't. What was he going on about?

Remus grumbled lowly in the back of his throat, looking at Harry desperately.

Harry wasn't looking at him now and he only saw Harry's eyes flit down to his briefly before they were up at the ceiling again.

"Giving up," Harry choked slightly at his words. Remus made to get up a bit but his leg refused, he couldn't just leave Harry to cry. With a final push he forced his leg to support him and he sat up weakly.

Harry looked down at him, his cheeks were streaked with tears and he wiped them away hastily, and sniffed.

Remus gazed at him intently trying to decipher what was going on in his mind. Harry stayed silent and Remus leant forward and nuzzled against Harry's damp cheek before licking Harry's hand sadly.

He looked up at Harry again, pleading with him silently to talk to him. In the smallest of whispers he heard Harry speak,

"Please don't give up on me,"

Remus lay back down again as his leg gave a jolt of pain. He growled in his throat again, sharing his indignation with Harry. He was not giving up on Harry and he was positive he'd shown that.

Harry shifted next to him and broke down completely burying him face carefully in a small part of Remus' uninjured back. Remus jumped he was not expecting that at all.

After a few minutes Harry's sobs reduced and finally stopped and he gradually shifted himself into a sitting position. Remus growled at him softly again.

"You're giving up on yourself," Harry said thickly. Remus watched Harry sit to face him.

He was right. Remus cared more about Harry getting hurt and was definitely considering that this would be his last transformation.

As if Harry had sensed this he carried on,

"...but you can't. You can't just leave me and give up. I need you, not just now but in the future. You help me incredibly in my third year. Without you I wouldn't have got through it..."

Remus felt tears well up in his eyes as he listened and lump was slowly rising in his throat. Something in his chest as well, but what that was he couldn't place at the moment.

Harry was still going.

"...you have...sorry will give me so much. Much more than just material possessions. You can't die now! My mum and dad need you as well, they wouldn't have got together without you and I really don't think they'd allow you to just give up on them...all of us...yourself,"

Remus sniffed quietly, tears were now streaming down his face but it was concealed by his fur and Harry didn't seem to have noticed as he continued his lecture.

"Sirius, he needs you to be his reasoning voice in the back of his head. You're going to help him in my third year as well,"

Harry's voice hitched in his throat as he remembered Sirius' last moments of life.

"...and you save my life in my fifth year. I'd have gone straight after Sirius if it weren't for you,"

Harry stopped and waited for Remus' reaction as he had done nothing but lay with his head on the floor staring up at him.

"So you see you can't die. We all need you,"

Remus whimpered slightly at this finishing sentence, he was about to push himself up again when Harry scuttled behind him once again and he stared up at Harry lost for a moment.

Harry merely pointed at Greyback, Remus followed the direction and felt his heart stop.

Greyback was stirring.

Remus glanced up at Harry one last time and felt the feeling in his chest explode.

It was survival...the will to survive. He pushed himself up determined and steadied himself watching Greyback fixedly.

Greyback opened his eyes slowly and peered around groggily.

Lupin felt himself bristle with anticipation, and readied his body and mind for the inevitable. He would win this, he would beat Greyback, he would protect Harry, and he would survive.

Greyback had now managed to get to his feet shakily and was staring around the room once again. Lupin moved in front of Harry and he felt Greyback's eyes fall on Harry. It was a wary look though, as if not sure what to make of Harry.

Greyback shook his head quickly, he needed a clear mind for this. He wasn't sure how long he'd been out but it was long enough for this other werewolf to get his strength back. He crouched low watching as the other werewolf mirrored him.

Remus growled menacingly at Greyback, he needed to make this quick sunrise couldn't be far away. Greyback had been out for a good few hours.

Remus attacked first going straight for Greyback's face. Greyback stood stunned he had barely seen Remus move and now it was too late.

Remus' plan was simple, to hinder Greyback's sight enough so he couldn't see and then mar him in some way to stop him from getting to Harry and himself.

His front paw connected solidly with Greyback's forehead and he dug his claws in. Greyback howled in pain and pushed Remus off feebly.

Remus looked at Greyback surveying the outcome of that first violent attack. Blood poured down Greyback's face from two long gashes on his forehead.

Greyback was shaking his head desperately as the blood ran into his eyes blocking his vision.

Remus sniffed slightly and paced in front of Greyback who was flailing his front legs from side to side trying to fend Remus off.

Harry watched this fight from the side of the cell. His pride had soared when he saw Remus get up again stronger than before. Now he was hoping that if Remus fell once more his wandless magic come back. His father had used it once but hadn't been able to do so since.

Remus watched Greyback's legs carefully, that could be a way to disable him. He moved to immobilize his worthy opponent.

Leaping forward he dodged under Greyback's left front leg, it skimmed his head. He clamped his jaws down on Greyback's right leg at the shoulder joint.

Greyback howled again, louder and more anguished than before.

Remus jerked his head sharply to the right, and heard a resounding snap thus ensuring the damage he intended.

Greyback whimpered and sank unceremoniously to the floor, sighing defeated.

Remus stood in front of him casting the werewolf a disgusted look and with a quick swipe of his front leg threw him against the wall.

He turned round and struggled his way back to Harry just as the sun rose.

A/N Ok what did you think?...I hope you liked it and please review they really make my day.
