Harry Black had always in his own opinion had a good life, he had a loving godfather who was always there for him and a werewolf uncle who was always able to give him guidance. He was a happy child which was surprising since his parents were murdered by Voldemort when he was 4 years old. Harry wasn't present on the night of the attack, he was staying with Sirius as his parents had to take his younger brother to France the next day to go into hiding as David Potter was the one who was prophesised to defeat the dark lord and was now being hunted. As much as it pained James and Lily they had to protect both of their sons and it wouldn't be fair to either child, but the best way to protect them was to split them up.
After a very emotional goodbye Lily and James left Harry in the care of Sirius and Remus. They were going to stay at the Black Country manor under the Fidelius charm with Sirius himself as the secret keeper while James, lily, David and Peter would be constantly on the move to make sure that Voldemort could not follow them. However before there life on the run could even begin, Voldemort had shown up at Godric's hollow and killed James while Lily retreated upstairs. All was quiet except for the crying child in front of him staring at the lifeless body of Lily Potter on the floor next to the crib.
Voldemort knew what had to be done, the child had to die. It was no fault of the child but, 'only I can live forever' he thought to himself. His mission was almost complete and as he raised his wand a sense of triumph came over him. However as the killing curse flew towards the child something happened, something unforeseen by the dark lord. The curse reflected off of the child and came back at him before he could react. He felt pain like no other as his very soul, or what was left of it was ripped from his body. A bloodcurdling scream could be heard and then nothing more. Both mother and child lay dead next to a yew wand. The wand was picked up and stowed away before a rat scampered out of the room.
When word of this reached Sirius he was already storming out of the manor on the hunt for his ex-friend with the intention of murdering him and would have continued if it wasn't for the level head of Remus and his quick thinking to calm Sirius down and stop him from doing something that could not be undone. They both went inside, Sirius collapsed on the couch, to in shock to feel any emotion while Remus hung his head over the bottle of whiskey in front of him. He poured two glasses and brought one over to his brother in all but blood not before slipping in a calming pill into each. They both downed it just as the floo lit up green. Out stepped a pale looking Albus Dumbledore who had just returned from the scene after checking for and trace as to what might have happened.
Throughout the next few hours and plans were discussed as to how they should proceed. The decision was made to leave harry in the care of Remus and Sirius with Sirius being the legal Guardian. They also decided it would be best for them to say that harry was Sirius's son and pretend that harry had died in the attack. With all the decisions made everyone left in a sombre mood. They would not meet again until the funeral which would be held a week from the day in Godric's Hollow. The war was over and the Daily Prophet would be printing the story of the tragic death of the potters and their sacrifice. However while the rest of the wizarding world would be celebrating the fall of the worst dark lord in history, Sirius and Remus would be mourning the deaths of the two of their best friends.
As Remus and Sirius retired to their respective rooms Harry was the last thought on both of their minds as they went to sleep. They knew that they would be left in charge, and both had their worries. Sirius didn't think he was ready to take care of a child and that his immaturity would lead to harry being raised poorly while Remus felt that due to his condition he could never be a respected father figure. They knew it was going to be a challenge to raise him but they would not risk the wrath of Lily Potter's ghost coming back and kicking their asses for messing up her son, and with that thought firmly in their mind they both shut their eyes and went to sleep.
When Sirius woke up the next morning he immediately went to check on harry in the makeshift room he had made for him. As he creaked open the door he saw a happy harry sleeping in his race car bed and began to feel the painful emotions as he thought about how harry would handle the situation. He was interrupted by Remus walking down the hall towards him. They both knew that they had to talk and went downstairs to the kitchen.
"What are we going to do" Sirius said as he began to prepare breakfast.
"The best we can I suppose" Remus replied.
A moment of silence passed as they both contemplated the future and what would happen in the coming years. How would harry react to being told his parents were not coming back, who would he grow up to be and how deeply it would affect him. This was broken by the noise of footsteps on the stairs. Harry had woken up and their job as co-parents had begun. They shared a look that said 'we can do this' and prepared themselves for what was to come.
