That morning, everyone was let back into their common rooms and dormitories, and Rosalyn rushed up the stairs alone, as Harry, Ron and Hermione had gone up already. But as she came to where the Fat Lady's portrait used to be, she was met with one of a knight and a fat grey pony.

Rosalyn recognised this picture, it was normally on the Seventh Floor, but the knight inside it, Sir Cadogan, spent most of his time riding in and out of other paintings, he could never keep still. He challenged people to duels most of the time, and if he wasn't doing that, he was heartily boasting to anyone who would listen.

Rosalyn sighed and said. "Fortuna Major," but it was denied.

"'Fraid not, Miss, changed it this morning."

"What is it then?" Rosalyn asked irritably.

"Not tellin' ya!" The knight roared with laughter and Rosalyn pursed her lips.

"Why not?"

" 'Cause if you don't know the password, you're not gettin' in!" The knight burst out laughing.

Rosalyn clenched her fists. "Let me in, or I'll-"

But just then Neville, still in his pyjamas, opened the portrait door, and Rosalyn slipped in, saying. "Bloody hope you don't stay, the Fat Lady was better, and that's saying something," before she ducked in the common room with Neville.

"Thought I heard someone arguing with him," Neville explained. "He keeps changing the password, it's been about three things just this morning, I've had to keep a list!"

Ron, Harry and Hermione were all there, pyjamas still on as Neville's were. Rosalyn sighed and said. "He really is an idiot, isn't he?"

Everyone agreed at once and Rosalyn went over to Percy, who was standing, fully dressed, over in the corner. "Hey Perce? Why'd we have to get him? Isn't there anyone else?"

"Sorry Rosie," Percy ignored what Rosalyn had called him. "But all the portraits were terrified, and he was the only one that stepped up, so you're stuck with him from now."

This news disheartened Rosalyn, if anything else, and she sighed, heading back to her friends.

The four of them separated so that they could all get dressed for lessons that day.

But, as the quartet joined back together for a late breakfast, Rosalyn told her friends what she had heard last night.

"Black was with a woman?" Harry asked. "But- but who? And why?"

"I don't know," Rosalyn said. "But if Dumbledore believed it, then it must be true."

"Or the Fat Lady was hallucinating?" Ron suggested.

"Oh really, Ron, I don't think that's likely," Hermione rolled her eyes.

Ron shrugged. "Alright, alright! I was just saying..."

Rosalyn shrugged, and tried to smile. However, even though she didn't bring the matter up again over breakfast, that didn't stop her thinking about it.

First class they had that day was defence against the dark arts, a class that had become Rosalyn's favourite in no time. She liked the way Professor Lupin taught them, and enjoyed the lessons he did with them.

Rosalyn, Ron and Harry walked along without Hermione, who had protested they leave without her as she was still getting ready. Rosalyn wanted to know why she was being so mysterious, but she didn't want to be nosy, so she put her mind to thinking about what Professor Lupin would teach them today.

However, when Rosalyn, Ron and Harry walked in, there was no Professor Lupin in the room. They sat down, taking out their books and wands, but still, Lupin did not show.

Ron said to Rosalyn. "Where is he? Didn't he say he was going to bring a hinkypunk in today?"

A hinkypunk was the next creature Lupin was teaching them about. As Ron had said, he had promised to bring one in next lesson, but at the moment, he hadn't even brought himself in.

Once the whole class was there, curiosity heightened. No one knew what was going on, or who was teaching them that day.

They got their answer when a very irritated Professor Snape walked into the class. His robes billowed behind him and an expression of intense dislike settled on his face. He walked up to the front, waving his wand at the shutters as he passed, which closed immediately.

When he got up front, he pulled the rope that rolled the board down and turned round as the white canvas fell down behind him.

"Turn to page three hundred and ninety-four," he ordered, putting stress on each syllable of the number, glaring down on the class as if they had committed crimes.

They all stared at each other before opening their books and turning to said page. Snape walked among them, staring daggers.

As he came to Rosalyn, she leaned out of her desk and asked him. "Is Professor Lupin on holiday, or..."

"Enough cheek, Potter," Snape snapped curtly. "And that's not really for your concern, is it?" He walked on, and answered airily. "If it suffices to say, your Professor finds himself incapable of teaching at the present time. Now, something that is for your concern, Potter, is doing what I tell you to, turn to page three hundred and ninety-four." He was now at the back, and he turned round, again, looking at the class with much hatred.

Ron's head was in his hand, and he was scrolling through the book one page at a time. Snape, clearly exasperated, waved his wand impatiently at Ron's book, which pages ruffled and landed at the right one.

Ron read the first few lines of the page and asked incredulously. "Werewolves?"

Rosalyn, who was just getting to the page, looked at it as well, annoyed, but not entirely surprised, that Snape wasn't doing what Lupin was teaching them, and, as Rosalyn thought, had told him to do.

Hermione thought this as well, and turned round in her seat to say. "But sir, we've only just started learning about redcaps and hinkypunks, we're not supposed to start nocturnal beasts for weeks."

"Quiet," said Snape in a warning tone.

"Don't tell her to be quiet-" Rosalyn muttered, but Hermione held her arm to stop her from catching Snape's attention.

"When did she come in? Did you see her come in?" Ron hissed to Harry, absolutely baffled. Hermione, however, just set about sorting her books one her desk and ignored the fact that she could hear Ron.

"Now," Snape walked slowly back up to the front. "Which one of you can tell me the difference between an animagus and a werewolf?"

Hermione was the only person that put up her hand, but Snape ignored her coolly, and sneered. "No one?"

"No, someone-" Rosalyn started angrily, but Hermione hissed to her.

"No! Rosalyn! Be quiet-"

"I suggest you take your friend's advice, Miss Potter," Snape said. "Be. Quiet."

Rosalyn clenched her fists and put her head down, trying not to be annoyed but feeling as though steam was going to come out of her ears all the same.

"Please sir," said Hermione, after a reasonable length of silence had prolonged. "An animagus is a wizard who elects to turn into an animal, a werewolf has no choice. With each full moon, when he transforms he no longer remembers who he is, he'd kill his best friend if they crossed paths. Furthermore the werewolf only responds to the call of its own kind."

Draco Malfoy, sling and all, made a howl that Crabbe, but no one else, laughed to. Rosalyn rolled her eyes and Snape wasn't impressed either, more at Hermione than Draco.

"Thank you, Mr Malfoy. That is the second time you have spoken out of turn Miss Granger. Are you incapable of restraining yourself or do you take pride in being an insufferable know-it-all?"

Hermione looked down at the desk and her eyes filled with tears. Rosalyn stared at Snape in a burning fury. Draco Malfoy and the Slytherins laughed, but all the other houses stared at Snape, fuming at him for bullying Hermione.

They had all called her a know-it-all at least once, but it had to be Ron, who called Hermione that the most, who stood up to Snape for her. "You asked us a question and she knows the answer! Why ask if you don't want to be told?!"

"Enough," Snape said. "Detention, Mr Weasley, it appears you can't hold your tongue either, and five points from Gryffindor, Miss Granger."

He turned round for a second and Malfoy took this as the moment to blow an origami paper bird over to Rosalyn.

Snape was talking again, stepping behind Lupin's desk. "On my desk on Monday morning, two rolls of parchment on the werewolf with particular emphasis on-" the class started moaning but Snape spoke louder, "recognising it."

The whole class groaned.

"Monday?!" Rosalyn gaped. "It's quidditch tomorrow - what are we supposed to-"

Snape went over to her desk and bent low over it. "I suggest you take extra care, Miss Potter, loss of limb will not excuse you. Page three hundred and ninety-four." He added, as he walked away.

He started to talk about werewolves but Rosalyn wasn't listening. She was opening up the piece of paper that Malfoy had flown over to her. What she saw just made her more annoyed.

It was a moving drawing of her, flying on her broom in a game of quidditch. She got hit by the quaffle and the weather turned to thunder, lighting and rain.

"Oh, very funny," Rosalyn rolled her eyes at Malfoy and stuck her middle finger up at him.

"Ohhhh, not friendly today, Potter?" Draco smirked. "Is something bothering you?"

"Your horrible face," Rosalyn muttered, pursing her lips, sighing and tuning back into Snape's boring drawl before she became the third member of the quartet to get yelled at by the potions professor that day.

☆☆☆

The weather wasn't very enthusiastic, but it was quidditch time anyway. Gryffindor were playing Hufflepuff and Rosalyn was on the pitch, waiting to catch the quaffle to start the game.

She didn't get it, but Katie did, passing it to Rosalyn as they flew towards the Hufflepuff end. But the weather was so bad, cloudy and rainy, that she soon didn't know where the Hufflepuff end was.

She passed to Angelina, yelling. "We have to try and find our way there!"

Angelina was great at it, and soon she scored for Gryffindor. Rosalyn bade her a well done and set down to business.

Katie, Rosalyn and Angelina worked together, but not a few moments later, the quaffle was stolen by a Hufflepuff chaser. He zoomed to the end and tried to score, but he missed because he couldn't see.

Rosalyn kept her fingers crossed, but by now, her hair was soaked, her hands were numb and her robes were heavy with water.

She tried to ignore this, however, and when Katie passed to her. She went right up to the goal, which the keeper wasn't doing a good job defending, and scored another goal for Gryffindor.

Claps and cheers rose through the stands for her and she smiled.

The next ten minutes were freezing, agonising, happy, and, of course, wet. Rosalyn had never been this soaked in her life, but she kept on playing, and scored another goal. Katie did, as well, and so did Angelina, she did two, but Wood was too good a keeper to let lots of goals through, even in fog and rain, and he managed to save all but one so far of the Hufflepuff's attempts to score.

Rosalyn was just getting annoyed at the Hufflepuff seeker, Cedric Diggory, because he was running his hands through his hair. Then she heard a whistle, and returned back to the ground, wondering what was up.

"I've called for five minute's time out!" Oliver Wood called to the team, and they gathered under shelter in the stands.

"What's the score?" Was Harry's immediate question.

"Sixty-Ten, we're fifty points up." Wood said, biting his lip anxiously. "But Harry, you have to get the snitch soon."

"I can't see!" Fred Weasley complained. "Can we just rearrange the match?"

"Yeah, otherwise a bludger is going to mess up our handsome faces!" George agreed.

Wood rolled his eyes and shook his head, but before he could give his excuse, Hermione came hurrying up to them.

"Harry! Rosie!" She yelled. "I've just thought of something, look, come here, I'll show you-"

She reached them and pulled out her wand, pointing it at Rosalyn's eyes. "Impervius!"

Rosalyn felt a sort of shield falling over her eyes, she could still see, but the rain couldn't get to her, it was great.

Hermione did the same thing to Harry's glasses, wished the team luck and hurried away, back up to the stands, where she undoubtedly came from.

With her new vision, Rosalyn got ready to go back out, and when she did, she felt marginally better.

She was flying over the pitch when a bludger, hit by a Hufflepuff beater, came at her, she flew up to avoid it and soon realised that, in the fog, she couldn't find her way back to the pitch.

Swearing under her breath, she suddenly noticed something, ice was forming on the end of her broom. She had the strange sensation that she was being followed, but then she realised that it wasn't strange, because it was exactly what was happening.

The dementors, flying through the air to her, at her back and front, were approaching. Rosalyn was extremely confused, as Dumbledore had said that they'd never leave the entrances, but that confusion soon gave way to fear as she ducked and swerved away from the guards of Azkaban.

There were three of them, closing in on her, forcing her to retreat. Rosalyn had to do a backwards loop the loop on her broom to avoid getting trapped.

Rosalyn ducked through the clouds, coming out the other end. She was suddenly in distress, as she could only see two out of three of the dementors. Where was the other one?

Rosalyn looked scared, but when the third dementor swooped in front of her, revealing its horrible mouth, she was terrified.

The mouth was horrible, teeth strewn everywhere, no tongue, nothing a bit human. But it was worse, in Rosalyn's opinion, to suddenly get your soul sucked out by them, as she was, now, completely under their control.

"Rosie!"

Rosalyn heard that scream again, though it was just her name this time, as she fell off her broom and tumbled through the air. She fell through the clouds and into the vaccinity of the pitch.

What she didn't remember, however, was Dumbledore putting out his hand and stopping her landing too hard.

"Arresto Momentum."
