Chapter One: A Padfoot Problem:

Severus Snape was in a fairly good mood, Voldemort was gone as were all his loyal followers completely, Harry Potter had just finished his seventh year at Hogwarts and Severus looked forward to spending time with his son, a son he had not known he had but a boy he loved dearly. He looked up as a small puppy made its way into his office and he scowled. Who had brought a puppy into his dungeons? It was all eyes, ears, fur and paws, it was black with gray eyes and looked up at him and whimpered. Severus got up and picked up the puppy and looked at him with suspicion. He checked the sex, male, then looked at the dog keenly again. He put the puppy down who whined at him but Severus just glared at the pup who whimpered up at him trembling as he did so.

"Turn human now Black." Severus said, "I know it's you so stop fooling around." With a soft pop a pale boy with shaggy black hair and gray eyes appeared before him. "Merlin Black you just have to be more of a problem than ever don't you?"

"Who are you?" Sirius asked, "where am I?"

"I am Severus Snape, head of Slytherin and potions master." Severus said.

"You are not! The head of Slytherin is Horace Slughorn!" Sirius said.

"Do not presume you know anything." Severus said, "come with me."

He picked the boy up finding him a solid boy, around eight Severus mused, he would carry the boy as his short legs could not keep up with him. He would drop him off with Poppy and speak to Dumbledore about this if he had to. Hopefully he could have Sirius re-aged back to his normal self in no time. So man and boy headed up to the infirmary, Sirius was still clad in his Weird Sister's tee shirt and jeans, so the potion had to have fallen on him, that gave him a clue and so he headed to the last class that had made potions and sure enough he found a broken vial on the floor with a bit of potion there. He put Sirius down, fixed the vial with a simple charm and collected the remains of the potion in the vial and put it in a rob pocket. Then he scooped Sirius up and carried him up to the upper floors…

…The last thing Sirius remembered was being sent to his room by his mother where he waited with dread for his father to come to punish him. He had not meant to get his headmasters mixed up, he really had studied but it would make no difference, he would be trashed and he hoped he would not cry out, he still ached from the last beating. When he came to he found he was a puppy and he had run into this tall scary man who seemed to know him. He looked sinister with his long straight black hair, hooked nose, black eyes and really pale skin. But he was carrying him, gently even, something his own parents never did, he could expect a smack or scolding at best.

He was taken up lots of stairs and down halls to a set of double doors and into a large room with beds along one side with large windows overlooking beautiful grounds. He saw a kindly woman clad in a starched gray gown and white apron with brown hair tied up in a loose bun with brown eyes. She had the tall man put him on a bed and undressed him to his underwear. He sat there and trembled when the tall man scowled, what had he done wrong? Why were they talking about him with concern? He looked down at himself, he had no cuts on him just some bruises, all bad boys did and he was really a very bad boy. Why else did his parents hit and beat him and tell him he was worthless?

When Severus put the small boy on the bed and Poppy had removed his clothing to his undershorts he looked at the bruises on him in anger. He knew that children, at times had a few bruises from roughhousing, that it was normal for a child to have a few scrapes and bruises but this, this was excessive. Most of them were on the child's back, from the strap of a belt. There were no welts or cuts and Severus realized in anger Sirius's parents would not want him scarred when they married him off. Part of Sirius's attitude in school was clearly learned at home and Severus did feel a bit sorry for the times he himself had tried to kill Black, then again he would not have if Black had not started it first. However now Sirius was a child in need of care and he would make sure he was cared for.

"Did your parents do this to you?" Severus asked.

"Yes sir, I was bad and deserved it." Sirius said looking down at the bedspread. "I will be better, please sir I will! Let my parents know I will be better."

"Sirius sweetie you were an adult not just an hour ago." Poppy said, "your parents are dead, your brother died in war, a hero."

"W-what of my cousins?" Sirius asked his lower lip trembling, "are they dead?"

"No, Narcissa is married happily as is Andromeda." Poppy said, "I cannot age you as I have to look at the potion."

"W-where will I go?" Sirius asked.

"I will take you." Severus said, "I am staying at Grimmauld place and have a son your age."

"You want me?" Sirius said, "but I am a bad boy!"

"I have not seen that, I want to take care of you." Severus said.

At the look of Poppy he realized he really was getting soft as here he was willing to take care of Sirius Black! Then again he was living at Grimmauld place for the time being as he had sold his house in Spinners End and was just waiting until his new house was built. He hoped he had not gone over his head in wanting to take Sirius but then again Sirius had been in his dungeons and had been de-aged there, oh Merlin he really was getting soft and is reputation was going to be tatters from this he just knew it!

So there is the first chapter of this little story. You don't need to read my Lions and Wards series to understand this story but it will help. Most notably the fact that Severus has a son, Sirius did apologize to him and both fought on the same side in the last war brining down Voldemort. There may be some corporal punishment but very, very little and I will warn if there is.
