News about the troll travelled around the school very fast. So fast, in fact, that she could hear Parvati and Lavender talking about it while her eyes were barely open the next morning. The two girls were astounded and impressed by the handiwork of the Potters and Ron and left not long after getting dressed to get breakfast. This was when Isabelle finally sighed against the rising of the sun and decided to get out of bed. Today was Saturday, and she decided she shouldn't spend it lay in bed, however tempting.

She swung her legs over the beg and lightly placed them on the scarlet carpet, trying not to wake Hermione, who was still breathing softly in her four-poster bed. Isabelle tiptoed silently to the bathroom and started putting her hair into a very short French braid. As she twisted the strands and interwove them into its plait, she caught sight of her eyes in the reflection. She looked more tired today than she had done in a while, this was possibly owed to the troll she encountered last night, or Quirrell before that, or the three headed dog before that…

In reality, Isabelle was struggling somewhat with all of the adventures. Perhaps she wouldn't feel so bad if she hadn't of had that run-in with Quirrell. It dawned on her that something wasn't right at Hogwarts but couldn't quite place it. Snape was suspicious too, the more she thought about that voice, the more she pinned it on him. How often did voices come out of nowhere? Not to mention his sudden concern for her when he was leading her away from Quirrell and back to the common room – it was no secret that Snape despised both her and her brother, Harry, after their very first potions lesson of the year.

In spite of all of this though, she had nothing against Harry. In fact, Harry was more wonderful than she could have ever anticipated. He was strong willed, determined and kind. His kindness shining through like his knight in shining armour. He was a little reckless, but even that stemmed by act of good-will, like deciding to stand up to Malfoy when no one else would.

In that moment, she silently vowed to herself that she would do absolutely everything in her power to protect her brother at all costs. She had only met him two months prior, and the thought of losing him made her feel colder than any physical thing could. She loved their late-night chats in front of the fire, and going on stupid adventures with Ron at their side.

When Isabelle had finally giving up trying to force her baby hairs into the braid, she decided that she was deemed presentable enough for the day. She exited the bathroom, silently pulled on her everyday wear, then exited the dorm. With a light step, she checked back to make sure that Hermione didn't stir. It was the weekend after all, and if there was anything Hermione deserved more than good grades, it was a solid bit of rest.

Once in the common room, Isabelle finally relaxed. She started heading for the portrait hole when she was abruptly stopped by a voice from one of the scarlet armchairs.

"Izzy, I've been waiting for you."

Isabelle turned on the spot to see red hair, a large grin and electric blue eyes staring at her. She paused for a moment as she tried to extract the name of the boy that was sat before her. It was one of Ron's twin's brothers – but the question was, was its Fred, or George? On the night of the sorting ceremony, she had promised Fred that she would not mix them up, but now, she was having a crisis. The only reason she finally spoke was because the twin started to frown and looked confused by her silent staring.

"Why have you been waiting for me?"

"Because Izzy, darling, you are vital to this prank we are about to pull."

Isabelle wined, "I'm not helping you with your prank, I've already got into enough trouble with the teachers without your influence as well."

"Lighten up, what's fun without a little mischief?" The twin winked.

Isabelle bit her lip. It was tempting. Since being at Hogwarts se had heard of all the pranks the twins had been pulling in passing whispers, the two of them were notorious. Many people in their year feared of being the next targets of their fun. She shook her head and cracked, "alright, what can I do to help?"

"You're the best! So, George and I heard that Malfoy was giving you, and our little brother a hard time the other day, so we've decided that its time he becomes our next target."

Ah, so this one is Fred, she thought as she took the seat next to him on the couch and tried to pretend that this wasn't more exciting to her than she was letting on. "Alright, so what are you thinking."

Fred cleared his throat dramatically before telling her, "I have absolutely no idea, that is where you come in."

Isabelle laughed as another voice sounded from behind her, descending from the stairs.

"Potter acquired," George grinned, "good one, Fred."

"She didn't need much persuading, trust me." Fred had told his brother, and the two of them had smirked at one another.

"Told you she wouldn't. I've seen the way she looks at him." George pretended to flinch, "if looks could kill."

Isabelle whacked him on the arm, trying her hardest not to smile before taking the conversation back on track. "So, what have you got so far?"

"We've considered charming a bucket of water to fall on him, or put dung beetles in his soup, that sort of thing." George continued,

"But nothing seems to match his level of evilness" Fred finished.

Proceeding her earlier confusion over the twins, Isabelle was quickly prevailing this issue. It occurred to her that there were very small differences in the twins, even if they were so alike that they could finish each other's sentences. Upon closer inspection, she noticed that Fred had a small, almost unnoticeable scar above his left eyebrow, and George had two small brown moles on his neck. As they spoke, Isabelle also observed the tiny curve that George's mouth took, whereas Fred's was minimally straighter. She was now observing their hair when something suddenly struck her.

"Hair!" she blurted.

She realised they'd need more information than that when they looked at her as though she was rapidly losing her mind.

"Malfoy has blonde hair, almost white. I think a few more than a couple of people would notice it if that were to change." She smirked.

The twins didn't seem to be catching on.

"Guys, we switch his shampoo for hair dye or something. We dye his hair."

Fred and George looked at each other for a long second before breaking out into large grins that took over their entire faces.

"Isabelle Potter, you evil genius. I'm so proud of you." George pretended to wipe a tear from his eye as Fred threw his arms around her and hugged her while she flailed against his embrace embarrassedly.

"Gerrof!" she protested between arms until he finally let her go.

By the time she had been let free, George had already dashed off somewhere, but it was seconds before he came bounding back over. He sat crossed legged behind the table that was pointing toward the fire. He pulled out a very old, tatty brown book from his robes and slid it across the table towards Isabelle. She went to pick it up, but before she could open it, George grabbed her wrists.

"Now, Izzy…" he started,

"This book is invaluable," Fred continued

"It's the secret to our every prank," the sentence went back to George,

Then Fred again, "your knowledge of this book does not leave the three of us, understand?"

Isabelle nodded, "sure."

She opened it up and found an array of different scrawls that she supposed were meant to be words and sentences. She squinted her eyes and decoded the letters. It described the effects of certain jinxes and what the counter curses were, certain sweets from honey dukes that could be enchanted, and of course, prank products as well that the twins had clearly invented upon their own accord. This was any prankster's heaven.

"This is brilliant!" She exclaimed, turning it to a new page. "So where do we start?"

"The library." The twins affirmed together, and then, the three of them set off on their new task.

The three of them searched in books all morning before they found all the information that they would need. It was essential that they found all the correct uses of potion items so that the potion worked, and then of course they needed an antidote.

This took a long while, but Isabelle didn't seem to mind with the twins. The three of them sat on a small table by the window, researching different potion ingredients and spells that they would need to achieve their goal. Fred and George already knew some of the products they would need before even picking up a book, which was helpful in the aspect of time. Isabelle knew that the twins were known for their sense of humour, but only appreciated it now she was immersed in the full experience. They were witty and funny, but also serious in a strange way, considering what all their seriousness was inevitably going to create.

Once they found everything they needed, they instructed Isabelle to head to the black lake and start setting everything up while they scouted their trunks for all the ingredients they would need for the task. By the time she had set up the flame and the cauldron, they were already by her side, laying out everything on the ground. The pair of them were in their element, and Isabelle was entertained enough to simply watch them.

"Now Miss Potter, if you will do us the honours?" George indicated forward, she nodded, and sat herself down cross legged in front of the cauldron and began setting herself off to work straight away.

She began by prepping the potion and then added all the ingredients, not forgetting to ensure to stir correctly. Fred was writing down everything she was doing as she did it, so that they could keep this prank for future reference if it was all to go well.

"I'm not sure if this is going to be a stupid question but, how are we going to make sure Malfoy gets the potion?" Isabelle asked, "I can't imagine he's going to drink from a curious bottle willy nilly."

"Easy," said George, "we'll send it to him by owl and claim to be a secret admirer."

She hummed, "Malfoy may be ego centrical but he's not stupid."

The three of them thought about it for a moment before Fred piped up, "we'll put it in some chocolate or something, that ought to work. In fact, I have some chocolate hearts upstairs. I got them from that Ravenclaw girl, George."

George laughed, "I'm sure she got the wrong twin. I'm obviously the more attractive one, isn't that right, Izzy?"

Isabelle blushed slightly at the wink he flew at her and shook her head in dismay. She wished they would stop laughing at her, because it was only making her blush more. This continued to amuse them for a while longer before George decided he would go and get the chocolate hearts from Fred's trunk to give him something to do now Fred was still writing down was Isabelle was doing, and she was making the potion.

"What about it, Iz? Do you find anyone particularly charming at Hogwarts? You can tell me; my lips are sealed." Fred was wiggling his eyebrows at her, and she shook her head again

Isabelle thought about it, and her mind wandered to her charms lesson with Dean, but quickly pushed that thought out of her head. "Not in the slightest. I have much more important things to be worrying about."

"You're a heartbreaker, Isabelle Potter."

She laughed at this one.

The two of them sat in a comfortable silence after that. The sound of the leaves rustling in the trees could be heard slightly over the sound of Fred scratching the quill against the old book. It was lucky that the day was warm considering it was now November when it should be getting colder.

It wasn't long before George had returned, and Isabelle was just finishing off the potion. she waved her wand a couple of times, allowing sparks to cascade into the liquid before deeming it ready to bottle up. As she poured the content of the potion into bottles, the twins looked delighted.

"Let's try it out then, do we have the antidote as well?"

Isabelle raised another bottle that she had prepared, as she started to dose the chocolates with the potions they had just made. In front of the her, Fred and George started to debate who would take the potion, but mid argument, Isabelle took a viral and downed it in one.

The two stated at her, then burst into cheers. She stood up and walked to the rivers edge and peered over to see her hair was a bright candy floss pink. She grinned at her work, trying to ignore the thoughts of how many detentions she would be put into if she was caught in these schemes. She finally walked back over to the twins, who were just coming to an end with their victory dance.

"It suits you, Iz. You should keep it like that." George applauded.

She flushed a little at the compliment, but before they could tease her for the redness of her face, she leaned over and picked up the antidote and took it. Within seconds, her hair was back to its usual dark brown colour, a few strands now falling over her face and out of her plait.

"Amazing. It worked first time!" Fred excitedly pointed at Isabelle's head.

"You can work with us again," George grinned, "you're amazing at brewing potions,"

"And finding those ingredients, she knew exactly what would make the hair turn pink without barely reading anything,"

"Not to mention she knows how many times to stir the potion without exploding it."

The twins were ecstatic. The two of them continued to talk excitedly as the three of them began to pack away all the ingredients and equipment they had laid out and stored it all away into their bags. Isabelle helped, but took extra effort to watch them jump about ang grin at their success. The two of them were the most mischievous people she had ever met, yet also so lovable. She now understood how the two of them could get away with all their pranks and yet be so adored by everyone in the school.

Once everything was packed away and there was no trace of a cauldron and a fire left, the three of them made their way up to the castle and headed straight for the Great Hall. The way up was a dirth track they had taken down the hill to the lake, and the breeze pushed against them. It was blissful. The closer they got to the castle, the more students they saw making their way towards the Great Hall. The corridors smelt strongly of baking cinnamon, and it wasn't until now that Isabelle realised how hungry she was.

The three of them found an empty couple of spaces at the Gryffindor table. Isabelle sat opposite the twins, who seemed to be more interested in wondering how long dinner would be than pulling off their prank.

"Now all we need to do is get it to Malfoy," Isabelle whispered, stirring the two of them back on track. Little did she know that Fred and George already had this covered.

"The owl must have been so disorientated. This isn't where Malfoy would sit" Fred said loudly,

"This girl mustn't like Malfoy that much if she doesn't even know where he sits." George then said. Isabelle watched them in amazement, how on Earth were they keeping straight faces?

"Perhaps we should eat the chocolate for him, I'm sure he won't mind"

"Hey!" Isabelle turned around to see Crabbe and Goyle stood cross arms behind her and staring greedily at the chocolates Fred was pretending to put in his mouth.

"If those are for Malfoy, then shouldn't you give them to him?" Crabbe cracked his knuckles, trying to look intimidating. In his defence, if he wanted to fight Fred and George, he probably could. He and Goyle combined could take on Fred and George, who in comparison were very tall, but didn't have much meat on their bones.

"You're right," said Fred, mocking a sense of disbelief in himself "how awful of us. Here."

Crabbe pulled the chocolates, that were now on a white plate, away from Fred. He and Goyle smirked at one another, before taking them to the Slytherin table. Isabelle was just finishing her hi-five with George when Harry, Ron and Hermione joined them.

"Isabelle," said Harry, taking the seat beside her, "I've been wondering where you've been all day. Dean Thomas said he and Seamus saw you leaving the library with Fred and George."

"Your friend would be correct," said George, not looking away from the Slytherin table. "Unavoidable circumstances, we needed to steal her from you for the day, sorry Harry." George said, but he didn't sound very apologetic at all.

"What have you been up to?" Ron moaned, noticing the glints in his older brother's eyes.

"Malfoy is going to showcase our days' work in a moment," said Fred excitedly,

That moment came very quickly, so quickly in fact, that Ron couldn't respond. Malfoy suddenly let out a great yelp from the Slytherin table and jumped straight to his feet. He looked so annoyed; Isabelle was sure his eyes had turned from their dull grey to a great fiery expression. He was the most flustered anyone had ever seen him – Afterall, he was always cool and composed, even in his moments of spite or jealousy. He then started shouting and ferociously trying to pull his hat over his head.

"You got them from where?"

"Those Weasley twins," Crabbe tried to explain, but Malfoy exploded in rage.

"You idiots! They're known for their foolish pranks!" Malfoy looked up, he noticed how much attention he was now bringing and made a break for the entrance hall door.

George raised his wand and casted a silent spell that caused Malfoy's hat to fly straight off his head.

Hermione gasped in horror, but Isabelle, and the rest of the hall erupted in a massive bound of laughter.

Malfoy, looking more embarrassed than he had ever done in his life, sprinted out. He tried to cover his pink head with his arms while Crabbe and Goyle tried to keep up with him.

"That was bloody brilliant!" Ron exclaimed through laughter,

"You ought to thank Izzy for all of this, it was her idea in the first place."

Harry, still laughing uncontrollably, nudged Isabelle and said, "they can steal you away more frequently Iz, if this is what you're going to get up to."

Isabelle grinned, caught the twin's eyes, then secluded back to her thoughts. If someone had have told her this time last year that she had met a three headed dog, battled a troll and created a potion that dyed people's hair pink – she certainly would not have believed it.
