Weasley's Wizarding Wheezes was crowded with Hogwarts students when Harry and the others arrived. Fred and George were wearing suits and greeting everyone and handing out samples. Harry received a huge gift basket of stuff, "What's all this for?" He asked curiously.

"That's for being our silent partner." Fred said beaming.

"It's thanks to your contribution that we're even here, mate." George told him. He hesitated, "Any word?"

"Not yet." Harry admitted seeing Ron looking on grumpily.

"Hey, how much for this?" Ron asked.

"5 galleons," Fred said.

"I'm your brother."

"10 galleons," Fred and George said together.

Harry sighed watching Ron stalk off in disgust. He noticed a younger girl at the cash register ringing up items and bagging purchases. "Who's that?"

"That's Fred's girlfriend, Mira." George told him. "She's an orphan, parents died in the last war with the Death Eaters. We gave her a room upstairs for her and her cat." As if on cue that small white cat looked over at them from the counter. "Strange cat, but she's good at all this, doesn't talk much, but there's just something about her."

Harry nodded. "Yeah, there is." He wasn't sure what it was though. He watched her curiously. Not staring, but definitely watching her. Her black hair and big eyes…there was something definitely familiar and then…it clicked. "She's a—" Harry whispered.

"What's that, Harry?" Sirius asked from his side.

"Mira," he nodded to the girl at the counter.

Sirius looked at her curiously and his eyes widened a little. Just then the little white cat looked right at Sirius. He hadn't seen him before, eyes going almost comically wide. Sirius just stared at that cat like he couldn't believe what he was seeing. Sirius strode across the store. "Excuse me, my dear," he said to Mira, "Could I borrow your cat for just a moment? Thank you." Before Mira could say or do anything, as she was busy ringing up and bagging up the customers orders, Sirius had grabbed the cat and was taking him to a back room going by Fred and George who looked curious but didn't stop him. The door closed to the back room the others were left to wonder what was going on. Sirius put the cat down on a box. "Okay, you, you'd better tell me what's going on." He said. The cat didn't say a word. "I'm waiting, Regulus!"

"You weren't supposed to find out." He finally said sighing. "I made a deal before I died, okay? If I saved a child from the dark I could live again."

"As a cat?"

"I can get my body back if I do this."

"And it's Mira you're going to save? I'm not blind, Regulus!"

"The child didn't matter! So long as I did save a child!"

"Don't act all self-important! You had ulterior motives!"

"Everyone does!" Regulus hissed.

"Does she know?"

"No! She doesn't know! The Dark Lord will not get his hands on her! She's already in enough danger with what she does!"

"Are you going to tell her?"

The cat's tail twitched and he looked down, small shoulders heaving a little. "She can't know…Sirius, she can't know."

The door flew open and Mira came in. "What are you doing to my cat?" She demanded wand out.

"Settle down, girl, he's fine." Sirius told her frowning. "We've been having a chat."

She closed the door. "He's my cat! You have no right!"

"He's my brother, I have every right!"

She stared wide eyed a little. "Y-you're…"

"I'm Sirius Black, girl! So I have every right to talk to him! You've known him what? 15 years? Less? I've known him twice that long! So don't think you have a monopoly on him."

"Sirius, that's enough!" Regulus told him. "Please, don't yell at her, she hasn't had an easy time being an orphan…"

"There are a lot of orphans, Regulus, many that lost their parents, she's not special. And she's not an orphan, like Erin was never an orphan."

"What are you talking about?" Mira demanded.

"I'm saying your parents aren't dead." Sirius told her.
