It was Hogsmeade day again, in the ice and snow and Rosalyn was watching the other students going off to the village, wanting to cry or throw something and see it smash.

But the she suddenly had an idea, and rushed away from where she was watching the students heading away with light hearts and cold bodies.

She sprinted down the stairs, then sneaked out the door, heading, hopefully, to Hogsmeade.

She knew she was making a slight sound as her boots compacted the snow with every step, but she had forgotten that she was making footprints as well.

She was worried about the cloak not reaching her feet, and went to make sure it was brushing the snow when two people that she knew very well grabbed her by the arms.

"Guys let me go!"

"Clever Rosie-" George started.

"-But not clever enough," Fred finished.

They were both wearing their winter coats and matching bobble hats. Rosalyn cursed herself for not dodging them.

George assured her. "Besides, we've got a better way."

"Come on, guys, I'm try'na get to Hogsmeade!" Rosalyn protested, struggling under the cloak.

"We know," answered the twins in unison.

"Don't worry-"

"We'll get you there-"

"We'll show you a quicker way-"

"If you pipe down."

"No, you absolute idiots-" Rosalyn tried to kick them in the shins but she didn't manage it.

They led her into the castle, where she protested further, and down a small corridor, there, Fred took over. "Now, Rosie, come and join the big boys."

She ripped off the cloak, demanding loudly. "What the hell are you doing?"

"Sssshh," Fred put a finger to his lips and handed her a blank piece of parchment. Folded up, looking suspiciously old, and, to Rosalyn, completely useless.

"Right, now you're just being stupid," Rosalyn rolled her eyes.

"Stupid, she says," George laughed, looking at his twin.

"This, Rosie, is the secret to our success," Fred poked the bit of paper with his wand.

"Bit of a wrench, giving it to you, believe me-" George said, tutting.

"But, we've decided, your needs are greater than ours," Fred looked solemn but Rosalyn couldn't tell if he was joking or not. "George, if you will."

George drew his wand like a conductor in front of a choir, then tapped the parchment, saying calmly. "I solemnly swear that I am up to no good."

From the place where the wand touched the parchment, ink started to flow, even though there was no quills in sight. The parchment suddenly had writing on it, and Rosalyn read it aloud intently:

𝕸𝖊𝖘𝖘𝖗𝖘 𝕸𝖔𝖔𝖓𝖞, 𝖂𝖔𝖗𝖒𝖙𝖆𝖎𝖑, 𝕻𝖆𝖉𝖋𝖔𝖔𝖙, 𝕻𝖗𝖔𝖓𝖌𝖘 𝖆𝖓𝖉 𝕸𝖘 𝕾𝖈𝖆𝖗𝖑𝖊𝖙 𝖆𝖗𝖊 𝖕𝖗𝖔𝖚𝖉 𝖙𝖔 𝖕𝖗𝖊𝖘𝖊𝖓𝖙

𝔗𝔥𝔢 𝔐𝔞𝔲𝔯𝔞𝔲𝔡𝔢𝔯𝔰 𝔐𝔞𝔭

"We owe them so much," Fred said seriously, after Rosalyn looked up from the parchment with a frown on her face.

"You two are idiots," she said, before she opened up the said map.

"You'll be eating your words in a few seconds, Rosie," George promised her.

And she was. She was astounded to see what she saw. "Hang on- this is Hogwarts- can that really- no- is that really-"

"Dumbledore," Fred nodded.

"In his study-"

"Pacing-"

"He does that a lot!"

It took Rosalyn a second to comprehend what they were saying, but once she got it, she understood.

"So you mean this map shows-" she started intending to finish, but she got cut off.

"Everyone," The twins said together.

"Everyone?" She asked incredulously. How could it do that?

"Everyone," Fred said again.

"Where they are-"

"What they're doing-"

"Every minute-"

"Of every day!"

"You to absolute knuckleheads are amazing for the first time in your lives!" Rosalyn's face broke into a grin, and she meant it. If this map really did what Fred and George said, then she could do anything. "How'd you get it?"

"Nicked it from Filch's office, of course," Fred answered. "From the drawer Confiscated and Highly Dangerous."

"Of course," Rosalyn laughed.

George explained further. "It was our first year, what d'you expect?"

"Now listen, there are seven secret passageways out the castle, we'd recommend, this one," Fred pointed at the map. "The one-eyed witch passageway. It'll lead you straight to Honeyduke's cellar."

"But you best hurry, Filch is heading this way," George pointed at the map again.

"Oh, and Rosie, don't forget, when you're done, just give it a tap and say-"

"Mischief managed," they said together, but only George tapped it. "Otherwise anyone can read it."

Sure enough, the ink on the map disappeared and it was again just the old piece of rubbish parchment that Rosalyn had suspected it to be.

☆☆☆

The next thing Rosalyn knew, she was lifting up a stone tile in the cellar of Honeyduke's. She had to check that it was clear first, and had to wait for a woman getting more jelly slugs to climb back up the rickety wooden stairs to the shop.

Eventually, she was able to get up and out of the tunnel. She took a few seconds to register that she was actually in Hogsmeade before throwing the cloak over herself and walking up the stairs.

When she got into the real shop, she saw why Ron had been so enthusiastic. All she saw was colour. Colour, sweets, and clamouring Hogwarts students, trying to get to the front of the queue.

She had to duck and dodge people on her way out the shop, but at the door, she saw Neville, Dean and Seamus. Seamus was talking animatedly to Dean and Neville was licking a lollipop. On the way, she inadvertently heard a bit of their conversation.

"...These sweets are amazing! I feel so bad for anyone who can't come to Hogsmeade..."

"Who is that? Is it just Rosalyn?"

"Yeah..."

"Well... she'll be okay," Seamus said.

"I hope she is," Neville sighed. "I don't want any more dementors or anything putting her in the hospital again."

Rosalyn smiled slightly, ducking out of the shop. She was glad that Neville didn't want her to get hurt, and she was also confused as to why some heat was rising up in her cheeks.

She lost her train of thought when she focused on trying to find Harry, Ron and Hermione.

She looked in every shop, everywhere, anywhere, but she didn't find them. But it wasn't until she saw Parvati and Lavender having a debate that she finally realised where they were.

"...Should we go to Zonko's? Or the Shrieking Shack?" Parvati was suggesting.

Lavender squealed at this. "No! It's supposed to be really scary, it's haunted..."

They're at the Shrieking Shack, Rosalyn suddenly knew. And she started to run up the snowy hill, slipping in some places but getting up eventually.

She ran up towards the signs pointing to the Shrieking Shack, just in time to hear.

"Well, well, look who's here, you three shopping for your new dream home?"

Rosalyn finally got up the hill, and came back down to see three people she wanted to see, and three she didn't.

Malfoy, Crabbe and Goyle were walking, or rather strutting, towards Harry, Ron and Hermione. Malfoy had his fur hat on, and expensive black cloak. Rosalyn rolled her eyes under the cloak.

"This is a bit grand for you isn't it, Weasleby, doesn't your family sleep in, er- one room?"

"Shut your mouth, Malfoy," Ron stuck up for himself, but half heartedly. Rosalyn clenched her fists.

Malfoy, meanwhile, was laughing. "Oooh, not very friendly. Boys, I think it's time we teach Weasleby how to respect his superiors." He fastened his cloak tighter.

Rosalyn wanted to give him a nice good slap-

An idea suddenly hit her. She bent down and picked up a large handful of snow with her gloved hands.

Hermione, meanwhile, had stepped in front of Ron and said. "Hope you don't mean yourself," with a laugh in her tone.

"How dare you talk to me!" Malfoy looked scandalised. "You filthy little mudblood!"

I just want to punch him in his stupid ugly face-

WHACK!

A snowball suddenly hit Malfoy hard in the face, smearing it with ice. The blonde boy jumped hard and turned to see who had thrown it, but no one was there.

Rosalyn was doubled up with silent laughter. She had chucked the snowball in her hand with all the strength that she could muster. Wanting to hurt him as well as make him freezing and angry.

"Who was that?" Malfoy asked, as Rosalyn suddenly made a decision.

She started forming snowballs as fast as she could, chucking them at a scared and yelling Malfoy, Crabbe and Goyle.

She crept near the three boys, and got close enough to pull Goyle's hat down, covering her eyes. She pulled Crabbe's trousers down, begging silently that he didn't go commando, then she held them down, and shoved him over, his bare legs and ugly face getting frozen by the snow.

Harry, Ron and Hermione were laughing more than ever as she took Goyle's Slytherin scarf and spun him round with it, knocking him over as well.

When she heard Crabbe and Goyle yelling for help from Malfoy, she took him by the legs, as he had tripped backwards over Crabbe, and pulled him up the hill.

She pulled him a long way until she finally let him go, then ran back, shoving Crabbe, who was trying to get up, back down again.

Harry, Ron and Hermione were teasing Malfoy as they ran up the hill, slipping and sliding on the ice.

When they were out if sight, but not our if earshot, Rosalyn went over to her best friends.

She lifted up the toggles on Ron's hat, Hermione's hair, and Harry's glasses.

"Rosie!" Hermione laughed.

She took off the cloak and laughed with them.

"Bloody hell, Rosie, that was not funny!" Said Ron.

"Yeah it was!" Harry smiled. "Got Malfoy back, didn't it!"

"Yeah, and it beat his ass!" Rosalyn sniggered.

They laughed as they walked away from the shack, and when they were back in the village, Rosalyn told them about her journey there, and her new possession.

"Those Weasels!" Ron complained about Fred and George. "They never told me about a marauders map!"

"But Rosie isn't going to keep it," The voice of sensibility, Hermione, spoke. "She's going to hand it to Professor McGonagall."

"Oh yeah, along with her invisibility cloak!"

They passed the pub, The Three Broomsticks, and Hermione laughed. "Oooh look who it is. Madam Rosmerta, Ron fancies her."

Madam Rosmerta was the owner of the Three Broomsticks, and she was outside it now, hammering up a sign.

"But old for you, isn't she, Ron?" Giggled Rosalyn.

"It's not true!" Ron yelled.

But then they had something else to think about. A sled carrying Professor McGonagall, and, to Rosalyn's surprise, the minister for magic, Cornelius Fudge.

They climbed out and Fudge said. "Rosmerta, my dear, I hope business is good."

Madam Rosmerta replied viciously, "It'd be alot better if the Ministry wasn't sending Dementors into my pub every single night," she went close to Fudge with her hammer.

"We have a killer on the loose!" Fudge took a few seconds to form a reply.

"Sirius Black in Hogsmeade? What would bring him here?"

Fudge leaned close to her eat and whispered, though quite loudly. "Rosalyn Potter."

"Rosalyn-"

"Sssshh!"

At that moment McGonagall, Fudge, Hagrid, Rosmerta and Rosalyn dashed inside the pub. Rosalyn was invisible of course, but she was still there.

Rosalyn followed the teachers up a spiral, wooden staircase and came to what she suspected to be Rosmerta's quarters. She opened the door closed by the teachers just a moment ago, and slipped inside whilst a confused Rosmerta closed it again.

"Now, tell me what this is all about."

McGonagall explained.

"Now, years ago, when Rosalyn and Harry Potter's parents realised that they were getting hunted down, they went into hiding. Few knew where they were, one who did, was Sirius Black. And he told you know who!"

McGonagall sat down, took a sip of her drink and Fudge took over the story. "Not only did Black lead you know who to the Potters that night but he also killed one of their friends, Peter Pettigrew."

"Peter Pettigrew?" Rosmerta asked.

"Yes, little lump of a boy," said McGonagall from the sofa. "Always trailing after Sirius Black."

"Ah, yes, I remember him, never let James and Sirius out of his sight!"

Rosalyn gasped under the cloak, her heart was beating out of her chest and she was wishing with all her heart that they were talking about a different James.

But her heavy breathing attracted Fudge, who was unscrewing a bottle of firewhisky. He looked straight at her for a few seconds, but then turned back to the conversation, which Rosalyn also did.

"So what happened?" Rosmerta was horrified.

McGonagall explained with a heavy heart, "Well, Peter Pettigrew tried to warn the Potters and might have managed to had he not run into his old friend, Sirius Black."

Fudge said dismissively. "Black was vicious he didn't just kill Pettigrew, he destroyed him," there was a murmur of assent and then Fudge held up his pinky, "A finger, that's all that was left, a finger!"

McGonagall spoke once more. "Oh, yes, Sirius Black may not have got his hands dirty in the murder of the Potters but he's the reason they're dead!"

Rosalyn couldn't believe her ears.

Rosmerta said. "I don't believe it."

And Fudge said. "And now he wants to finish what he started, Rosalyn and Harry-"

He stopped, and McGonagall said. "But that's not the worst of it."

"What could be worse?" Rosmerta said what Rosalyn was thinking.

"Well, James and Lily, named Sirius the- the guardian of their first child."

"So-" Rosmerta's eyes were wide.

"So, Sirius Black is, and remains to this day, Rosalyn Potter's godfather."

"But I though that-"

Rosalyn didn't want to hear anymore. She ran out the pub, through a practicing choir and to a rock in the snowy outskirts of Hogsmeade.

She was crying, tears caressed her face and sobs wracked her body.

She was aware of Hermione lifting the cloak off her, and looked at her, Harry and Ron. They deserved and explanation.

"He was their friend, and he betrayed them." A sudden anger took over her as she said that. "HE WAS THEIR FUCKING FRIEND AND HE TOLD VOLDEMORT WHERE THEY WERE! He's the reason they're DEAD!"

Her body wracked with sobs as she bellowed these words out. She looked at Hermione, who was knelt in front of her, and Harry and Ron, who were looking sad.

"Rosalyn..." Hermione said sadly, tears in her eyes. "Listen-"

"I hope he comes," Rosalyn said savagely. "I hope he comes and he finds me, because when he does, I'm gonna be ready for him and I'm gonna kill him like he killed them!"

That, mixed with the betrayal of what she had heard today, and who Sirius Black really was, made her sadder than ever. The person who betrayed her parents was coming. And she needed to be ready.

But what she didn't think about, was what Madam Rosmerta had said.

"But I thought-"

She said that after McGonagall said that Black was my godfather.

So did she think someone else was my godfather? Or even godparent?

She didn't know.

But something was going on.

A woman with Black.

A girl Lupin used to know.

And an unsure Madam Rosmerta.

They were all connected somehow, Rosalyn just knew it.
