chapter 3

(a/n- thanks so much for reviewing! i'm really happy you like it so far! here's the next chapter.) (disclaimer- all characters except Mary belong to JKR)

Sirius Black sat in his Azkaban cell, just wanting it all to be over. Still, after 7 years, the pain from James and Lily's deaths were as fresh as the night that they had happened. He just wanted a friend that knew the truth, that knew that he was innocent.
His wish came true.
The cell door creaked open and a woman with long brown hair was thrown inside, and the door was slammed shut. It was Bellatrix Lestrange, his cousin, a death eater. He glared at her with the utmost loathing before returning his attention back to a picture he was drawing in the dust with a stick. It was of Lily and James, so happy together, and baby Harry.
Sirius smiled weakly, and burst into tears. Why James and Lily? Why did it have to be them? Why couldn't he have died instead?
A gust of wind came in through the window and blew away the picture.
All of the sudden, Sirius heard a soft pop! behind him and turned. His cousin was changing. Jet-black, untidy, shorter, hair was sprouting and taking place of the long, brown hair. She was shrinking and her eyes changed from dark brown to vivid green.
Sirius gasped.
"No!" he thought, "It can't be! How-how would she get here?"
But he realized: It was her. It was Mary Potter.
She stared at him for what seemed like and hour and finally said, "Have I met you before? Who are you?"
Sirius still could not speak, but he finally managed to gasp out, "Mary! You must not remember me....you were too young.....but I'm Sirius Black. I was your parents' best fr-"
But he never managed to get out the last word, because suddenly she jumped on him and hugged him so hard he couldn't breathe.
"Oh, Sirius!" she cried, "I don't know why, but I remember that night perfectly, and I knew you hadn't done it! I couldn't believe it when you were imprisoned! I had forgotten you were here! I-I...." her voice trailed off and she started to twitch convulsively. She looked up and saw a dementor hovering over her. She passed out.
"Mary! Mary!"
Sirius was shaking her, and she regained consciousness.
"Wh-what happened?" she said. "Everything got really cold, and I saw you crying over my parents' bodies and then everything went black."
Sirius frowned and turned angrily toward the dementors.
"How dare they?" he thought, "After all she's been through! We are going to get out of here one way or another."
"They're dementors. They make you relive your worst memories and suck all the happiness out of you," said Sirius.
"Oh," Mary replied sadly. She didn't want that to happen again.
"But I may be able to help," he said. "I've read about a way to do it without a wand or making a potion. It's extremely difficult and requires a ton of natural magic, but I can tell that you have a lot of natural magic, which is high in some witches and wizards, and low in others," he realized that he had started muttering to himself and that Mary had no idea what he was talking about.
"Er-what are you talking about?" she asked, very puzzled.
"Mary," said Sirius, "I am going to help you become an Animagus, like myself. The dementors won't affect you if you're an animal."
"Oh! I think I've heard about those! You can turn into an animal at will. But you're one? I looked it up and I didn't find you on the list."
"There are probably many that the Ministry doesn't know about," he said, "but there were 3 unregistered Animagi running around Hogwarts when I went to school. Peter Pettigrew, James Potter, and myself. Peter, the scumbag, could turn into a rat. Funny, sometimes the animal really describes the person well. Your father could change into a stag, and I could change into a black dog."
Then, he bent down close to her and whispered,
"That's how we're going to get out of here."
