Ohhh boy. I don't own Harry Potter. Any moron who believes they do doesn't obviously realize how quickly they'll be marked the village idiot.

It's been thirteen years since she's last seen them, the incident of the Potter's hurting her deeply. The rumor's of it spread like wildfire – and despite each one ending in the fact that both James and Lily had died, they celebrated because Voldemort (she winced) had disappeared as well.

She stretched out her front legs, her claws expanding, her back arching. Not everyone knew the truth of that night – about how the Potter's weren't betrayed by their best friend – but by a spineless git whose jealousy affected the best of him. She meowed, tired, and walked over to her bed on the floor in the corner behind the clerk's desk, and laid herself down, tired.

She heard him pleading to a giant, asking him to give the small child to him. When the giant refused, she could see the disappointment in his eyes – the sadness that was within. His best mate was dead, his best mate's wife, who was like a sister – met the same fate. His godson, now in the hands of a giant, wasn't even going to be his. "Professor Dumblerdore's orders," he said, and she could hear sadness within the giant's voice as well.

She hid behind a rock, crouched, and watched intently as the man gave in, and told the giant to take his motorcycle. She watched as the giant accepted, and took off upon it into the sky. Not a moment later did she see the man just stand there starring off into space, when he suddenly turned rigid with fury.

She stepped up from behind the rock and towards him, patting the bottom of his leg with her paw. Alert, he looked down at her. "What are you doing here?" His voice was cold, but the coldness wasn't directed towards her.

"Same reason why you are," she said, fully transformed now.

"I'm going to kill him."

"What?" She looked at him, her eyes transfixed. "Kill who? Voldemort –"

"Not him," he shook his head, his body now shaking. "Peter."

"W-Wormtail? Sirius – look at me, will you?"

He didn't. "He was their secret keeper."

"But – Wormtail wouldn't – he –" she touched his arm.

"He betrayed them," he shook her hand away from his. "And I'm going to make sure he meets the same fate as his master."

She looked at him for a minute, and then nodded. "I'm going with you."

Finally, he looked at her and didn't say a word. She blinked, and he was gone. In his place was a shaggy black dog, who blinked at her before turning around and started at a sprint down the street. She transformed into her ginger form and sprinted after him.

She saw everything after that – the burned visions a permanent memory. Pettigrew got away, but not without a fight. She closed her eyes and curled her tail around her body.

She watched in the middle of all the confusion as Peter Pettigrew cut off his finger, and transform in the midst of everyone focusing on Sirius Black. Anger shot threw her body as she saw Peter transform into his rat form, making his way towards the nearest sewer. Still in her transformed body, she chased after him, diving down the sewer after him.

Covered in dirty water and muck up to her furry belly, she chased Peter down underneath the street, tracing down any blood marks she sees, and red water in her way. Finally, she caught up to him, his furry body drenched and covered in his own blood. She sneered at him, and crouched low. She pounded at him, catching his tail between her paws.

He squealed as she pulled him towards her, his body now in her mouth. She turned and ran, trying to find an escape path, when suddenly she felt a vibration in her mouth. Peter transformed back into himself, knocking her back into the concrete wall.

Then just like that, he transformed back and he was gone.

When she tried to find Sirius after that, she heard he was arrested and taken to Azkaban. She spent weeks in her form, searching every nook and cranny. She spent her days underneath London in the sewer, pouncing any rat she sees. Tired, she made her way to an open drain and clawed her way out.

When she did, she found herself out in front of the Magical Menagerie. Thirteen years later, she's still there. With a small stifle of a yawn, she fell asleep, Harry Potter on her mind.

Author's Note: I'm rereading Harry Potter and the Prisoner of Azkaban, and I found myself falling in love with all the characters once again. Crookshanks is such an intelligent creature, and even though in the book the animal is portrayed as a male as well as just a cat – I thought it'd be interesting to put a little spin on it. Adios, Tricia
