To gain a Big friend.

Lucius sat on the floor with Harry playing with a Hogwarts express train set which came complete with choo choo action –being made by Lucius himself. Harry giggled and lost himself in the childish game he and his Papa were playing. It had been two days since Sirius was arrested and he had heard from an associate that morning that he was being sentenced to four years in minimum security because he had co-operated with the Auror's and Remus who had left early that morning presumably to find his mate.

Severus had just come in from his potions lab when there was a knock at the door signalling someone's arrival. Severus walked to the door and allowed Remus in along with Regulus black unsurprisingly however what was a surprise was the man who walked in behind them, the very man all death eaters had feared when he joined their ranks Fenrir Grayback. Instantly Lucius was on his feet and had scooped Harry up into his arms, while Severus pointed his wand at Grayback's heart.

"Remus what the hell is he doing here, why would you bring him to Hogwarts somewhere that children are and especially anywhere near Harry!" Severus's voice took on a slightly hysterical tint towards the end.

"Severus calm down. Albus let Fenrir into the castle after we explained the truth to him, if you will calm down we will explain what is going on." Remus said moving to stand before the very man he had always said he hated.

"Alright you can explain but he goes not were near Harry until we say so and are satisfied with the explanation" Severus said moving around to sit by his husband who was on the Love seat holding Harry so Fenrir could not get any were near him. Harry however had other ideas, as soon as Lucius marginal relaxed his grip once Grayback had sat on the chair opposite with Remus in the chair next to him which he had transfigured into another Love seat for him and Regulus. Harry wiggled out of his grip and ran across the room before stopping before Grayback inches away. Harry looked up into the man's face for a moment before turning to the rest of the room and declaring.

"Big man is nice, Daddy put your wand away" and climbing up and depositing himself on Fenrir's knee. Fenrir looked down at the child on his knee flabbergasted that the little one had trusted him so easily when most of the cubs born to his pack were scared of him, however his heart soften when he looked into the expressive green eyes before him and pat the boy on the head before the child got off his knee and went to sit between his fathers. Lucius and Severus were torn between scolding Harry for going to someone he didn't know and passing out after seeing Fenrir be nice to a child. So the settled in the middle and glared at Grayback who smiled in a rather wolfish way. Remus cleared his throat before motioning for Fenrir to speak.

"Not many people know it but I am Fenrir Grayback Jr. My father was the pack leader before myself. He had a wandering eye as he had never matted with anyone, in the summer of 1959 a witch caught his eye, her name was Julia Lion he slept with her –consensually of course- then left. She soon found out she was pregnant in the September and had convinced John Lupin a local muggle boy to marry her by the November. Somehow she convinced him that the baby was his, I believe she gave him a potion.

"It was three years after my father's death and when Remus was four I found out about all of the cubs my father sired. It is not well known that but a child is not born a werewolf they do however have the gene to become one and if it is not activated within the first ten years of life the child will go insane and die. I worked from oldest to youngest, turning a child of my father's whenever I found one after their parents cast them out I would take them to my pack.

"I found Remus when he was six, we was playing outside on the night of the full moon and I recognised him as one of my father's straight away however I also felt a pull to him that I had not to any of the others, I thought of him as my cub, I realised then that I had found my heir so even if I had a child Remus would still be the next one to take over the pack. The problem came the day after I bit him, rather than cast him out like his mother wanted, Remus's father kept him and loved him no differently than he always had. His mother on the other hand had a good idea who I was and poisoned him against me.

"I managed to track him down when he was 13 it was the day after the full moon and he was at his home. His father was working away and his mother had go to the other side of town to visit a friend but she had not let her son out of the reinforced shed that he was kept in on the full moon. I let him out and fixed him up. I spent hours talking to Remus explaining who I was and why I change children. After that Remus spent at least four weeks a year with the pack.

"As for why I joined the Death Eaters. He had the Pups of three of the wolves in my pack, I was put in a position where I would be forced to join or watch four children tortured into insanity. It was an easy choice, I was lucky that my reputation made sure the other Death eaters kept out of my way for fear of what I would do to their children. There is one thing you should know and that is I would never hurt a child and I only ever turn a child if they have the werewolf gene. So you need not worry Harry and every other child at Hogwarts is perfectly safe." Fenrir finished his tale slumping back against the chair he was in as if reliving the past had taken a lot out of him.

Lucius and Severus sat silently for a moment trying to process the information that they had just been given they looked down at Harry who repeated what he had said earlier.

"Big Man okay" Harry said smiling when Fenrir started to laugh at the childish assessment of him. He and the others stayed with the child and his fathers until it was time for Harry to go to bed. At which point all of the man in the room gave him a hug even Regulus who he had been wary of at first due to his resemblance to his brother but had warmed up to the man when he gifted him with a colour change dragon which changed colour depending on how the child who owned it felt.

When it came to Fenrir giving Harry a hug he told the little boy he would come back and tell him stories of his packs legends which excited the small boy no end. Before he left Remus turned around and asked

"You are ready for Harry's Birthday tomorrow right" Severus and Lucius both laughed and nodded because even with the recent excitement they would never forget Harry's Birthday. They arranged to meet in the great hall at twelve the next day for Harry's birthday Lunch and Party.
