Some weeks had past and Hermione was on her way to Draco's quidditch practice when she saw a large black dog. The dog wined at her and she could see the poor dog looked hungry.
"Missy"
"Yes mistress?"
"could you bring me some meat?"
Missy popped away only to return with more than enough food in a picnic basket. Smiling she slowly approached the dog and sat down on one of the large rocks.
"hello there. Are you hungry? Are you lost?"
The dog slowly approached and took the meat gently from her. As soon as he was close, she laid her hand on his back. The second she touched him his fur regained a healthy appearance to which the dog seemed to sigh at.
"how odd, that same thing happened when I touched grandfather for the first time. You're not a dark wizard, are you?"
The dog shifted into a man who was Sirius black.
"depends on who you ask, but no. I won't hurt you I'm only after the rat."
Hermione sat still looking at her godfather in shock but also at the fact her cloak did not appear.
"what rat?"
"interesting you have no problem talking to me"
"well, you are my godfather, and my grandfather is Grindelwald so you're not that scary actually"
The man was shocked and sat deep in thought mumbling about the blood lines.
"it's a long story"
"right, the rat is petter Pettigrew"
"but you killed him"
"apparently I missed. Strange before I was angry almost insane but now. Oh, pup you must have inherited your mothers' gift."
"oh, what gift"
He nodded and sat beside her clearly gathering his thought.
"your mother had a gift. With a single touch she could remove the effects of dark magic. The black well my mother taught me black magic as soon as I could walk. I hated it but there was not much I could do. Not to mention all the dark and cursed items in my childhood home."
"it effected your mind"
"yes, she cleared me of its multiple times but 12 years in Azkaban."
"damaged your mind"
"yes, well until you pup"
He nudged her shoulder and looked around in worry.
"the rat I need is Harrys friends familiar."
"Longbottom has a toad"
"no, the red head"
"oh Ron, he's a prat"
Sirus laughed and nodded.
"oh, I've heard some of the things around here. So Slytherin?"
"yes why"
"your grandmother was Slytherin. Oh, Mother Dora was not a woman to cross. At the end of fifth year, I ran away from home and moved in with them. When she saw the scares, my own mother had done she marched over there and dueled her. My mother was her niece."
"really?"
"oh yes, which was why the ministry couldn't make me go back. She was a member of the ancient and noble house of black."
"you're going to kill him aren't you, the rat"
"I was but now that I can think clearly ill catch him somehow."
"give me a day and I will have a plan"
"oh"
"of course, I am a Slytherin after all. Here take this with you need to go before Draco comes looking for me."
He watched as she ran off to the pitch as her father approached from behind.
"how much did you hear?"
"all of it. I believe there is more to your story?"
"yes, tea?"
"come along dog"
"snake"
He shifted back and waled beside Severus in silence straight to the headmaster's office.
Draco and Hermione were deep in thought of how to help Sirius. They knew of the spell that would force a Animagus to reveal them sleeves but how would they explain knowing there was one in the castle. It was not until late in the night they had their answer. The next day before class they took their suspicion to Professor McGonagall that there had to be an unregistered Animagus in the castle. That would explain who black was getting in and how he escaped Azkaban. So, at the end of the day all students were to bring their familiars to the great hall. What surprised them was Sirius was standing there in cuffs with aurors.
"he turned him self in." harry was beside them with his owl.
"why?"
"no clue but apparently Pettigrew was an unregistered Animagus and so is black."
No one spoke as every animal was tested but when it came down to Ron's rat everyone screamed. There trying to run a way was a man known as peter Pettigrew.
"well as you can see mister minster, he is alive and well. Oh, check his arm while you're at it."
The dark mark was there and soon the sniveling man turned shouting about how he turned and told the dark lord where to find the potters. While they were dragging him away, he shouted out everything and by doing so cleared Sirius of all his crimes.
Draco took her hand as they were dismissed to leave only of the pair and harry to stay behind. The hall was cleared and only her family stayed behind including professor lupin. They talked for hours until curfew to which they were dismissed. An innocent man was freed, justice was served and the dementors were sent away. The light had won that day and one more shadow was removed from Hogwarts.
