"Should we really be doing this?"

"After all the pranks we've pulled together, this is the one that makes you nervous?"

"It's not the prank that makes me nervous, it's the people we're pranking! You know how they are when they get mad"

"True, but just think of it as payback"

"For what?"

"For all the times they ever ruined our pranks"

Fred and George were hiding round the corner closest to Ginny's bathroom, watching and waiting for it's occupants to leave the premises so they could begin their plan. It had been a prank that had been in the works for weeks now, but they had just never had the right time usually Ginny was off with Harry and Hermione was often using her free time to go visit Charlie in Romania, the twins had a sneaky suspicion those two were more than friends and would get to the bottom of that eventually, but for now their first step of their plan was to get into that room and out again without being noticed.

George opened his mouth to say something again when the door finally opened, he promptly shut his mouth and watched as the two girls left the room, laughing and giggling at something. They waited until they had gotten to the bottom of the stairs and disappeared into the kitchen before making their move. They both tiptoed into Ginny's bathroom and locked the door, making sure to by themselves some time to get this done.

Fred turned around and his eyes widened at the various different coloured bottles that lay in the bathroom. "Uh, George? What one do we pick?"

George rolled his eyes, "Just pick the one that says shampoo or conditioner, duh"

Fred nodded before searching the different coloured potions, honestly how many did girls need? Surely they only needed a few, but this many? He shook his head in disbelief before managing to find a dark purple bottle which was labelled as shampoo, it also happened to be labelled as Hermione Granger's shampoo. "Perfect"

Together Fred and George both poured a different potion into the girl's shampoo, it deserved them right for trying to prank them before they left Hogwarts for Christmas, this would teach them not to mess with the prank lords.

"Done?" Fred asked

"Done" George confirmed

The twins unlocked the door and opened it silently to listen out for any incoming footsteps or voices, when all they heard was silence in return they then went to Ginny's door, pushing it open slightly they accioed a bucket and slime from their room before placing it carefully on top of her door. George chuckled as he made sure the bucket was in position before they retreated to their bedroom.

"Hermione will regret teaching us those muggle pranks" George grinned

Fred nodded, "I still can't believe that we managed to persuade her into showing us! I thought I would never see the day when Hermione Granger actually helped us out"

"True" George admitted, "But it happened and now we have a whole new branch of Weasley products to test on the first years. Granger can't get mad because they're not dangerous"

"Valid point Forge" Fred grinned.

The twins fell silent just as Ginny and Hermione began to make their way back upstairs armed with two mugs of hot chocolate and a plate of cookies, they had been spending the majority of their Christmas holiday's together as they usually would but this time they had been reminiscing about the Hogwarts Gossip, the one they were currently engrossed in that was Lavender Brown was apparently in love with Professor Flitwick, which to be honest didn't really surprise Hermione or Ginny considering Lavender was boy crazy.

The boys peaked out of their bedroom door as Ginny flicked her wand to open the door, as they stepped through the bucket of slime that had been balancing carefully on the door, slipped from it's position and covered the unsuspecting witches in green slime. The plate of cookies and mugs of hot chocolate fell to the floor in a loud thump as the girls stared at each other in shock. Fred and George were barely silent for a minute before they erupted into laughter which alerted Hermione and Ginny to their presence.

"FRED! GEORGE! WE ARE GOING TO KILL YOU" Ginny yelled, or tried to yell as the slime dripped into her mouth.

"Now, now sister dearest. That would be a shame" George grinned

"We are your favourite brothers after all, and we've taught you so much" Fred continued

"Killing us wouldn't really be repaying us, it would just cause us to haunt you for rest of your life"

"And you wouldn't want that would you?"

Hermione huffed in annoyance as she wiped the slime from her eyes, she stalked over to the two older boys, standing at her full height which was barely to their chin but still seemed menacing to them anyway and glared into their eyes. "I expected more of you two. After all your elaborate pranks this is the best you can come up with? This was...tame compared to your usual standards"

Fred and George both attempted to seem stunned by that accusation, when in face covering them both in slime had only been step one in their prank, step two would be once they both showered and covered their hair in shampoo, then the fun would really begin.

"You wound us Granger" George sighed and fell against Fred's shoulder, his hand pressed to his forehead as if he were a damsel in distress.

"How dare you call us tame! This is a catastrophe!"

"An outrage!"

"A complete and utter lie!"

"We will rectify this matter at once. Good day to you both!"

With that the twins shut their bedroom door in Hermione's face with an almighty slam, and for a second Hermione thought it might come off the hinges and actually hit her in the face but when it didn't she huffed again and spun round to march directly towards the bathroom to get herself cleaned up.

Fred and George were downstairs when it finally happened, the girls had spent the better half of an hour showering and trying to remove all the goo from themselves which actually seemed like an impossible task with Hermione's hair, it got tangled in places she never thought it could get tangled. As they sat in the kitchen and talked over a cup of coffee they could hear the footsteps coming in and out of various rooms, just when it seemed that they would have to intervene the noises from upstairs stopped. The house went completely silent, the twins stared at each other while identical grins spread across their faces.

"FRED!"

"GEORGE!"

Thundering footsteps were heard on the stops and in what seemed like seconds, the angry witches were in the door way glaring at the twins. As Fred took in the angry looks on both of their faces, he happened to notice that Hermione seemed to be the angriest, her eyes were narrowed into slits and her face was turning a very deep red while she stood with her hand on her hips. He let his gaze move from her face to her hair and within seconds he burst into laughter.

George soon followed suit as he finally looked at both Ginny and Hermione's hair, or should he say lack of hair. Hermione's hair had been turned a vibrant orange but rather than being styled in her usual loose curls she was now sporting a very adventurous Mohawk, with the back end being suspiciously styled into a tail of a dragon. While Ginny's usual dark orange hair which usually hung straight down her back, was now a Slytherin green but had pieces of gold through it which happened to be in the shape of a golden snitch.

"What have you done to our hair?" Hermione growled

"We don't know what you're talking about" Fred shrugged, sipping on his coffee with a mischievous glint in his eyes

"Oh you know exactly what we're talking about Fredrick Gideon Weasley" Ginny took a step closer to the table, an eerily calm expression on her face as she stared down her brothers.

George chuckled and leaned forward, clasping his hands together and resting them on front of him on the table. "Well since Hermione usually gives us such a hard time about testing our products on the younger generation, we thought we would try a different approach"

"And you thought testing your products out on us would be a smart idea?" Hermione questioned

Fred nodded, still grinning, "Naturally"

"You two are idiots! How could you do this to us? We look bloody ridiculous, not to mention that Harry and..." Ginny stopped before she could continue and glanced worriedly at Hermione who in return sent her a pointed look to not continue with her sentence

"Harry and who are doing what?" George perked up with interest, taking notice that Hermione was going even darker shade of red.

"Nothing! I just meant Harry and one of our friends are coming over and we're going to look horrible for them!"

Fred and George exchanged a look, their little sister was clearly not telling them something and that sparked their curiosity. "Sure Gin"

"If we're to believe that it's just Harry and one of your 'friends'" George air quoted at the word 'friends'. "Are coming by then we would just be as gullible as the toad believing that there was really a secret weapon in the forbidden forest!"

Ginny groaned, she hadn't meant to throw Hermione into the deep end but she had just been so angry at her brothers she didn't realise what she was saying. "It's none of your business! The big question right now is how long will this last?"

The twins shrugged, identical grins once again on their first. "Who knows" Fred sighed

"It could be minutes"

"Or an hour"

"Or 24 hours"

"Or a day"

"Or a month"

"Or..."

"WE GET IT!" The girls yelled in unison

Hermione stormed over to the table and grabbed Fred by the cuff of his shirt, her eyes blazing with anger and embarrassment. "If you don't change us back right now we'll tell your Mother"

Fred rolled his eyes, "Oh please Granger, back in school that would have worked on us. But we're grown men now, the threat of telling our Mother doesn't frighten us. Plus, it also helps that she's not currently at Home and won't be back for another day or two so you're out of luck"

Just as Hermione opened her mouth to speak, the sound of the floo activating in the liven room alerted them that someone had just entered the house, Hermione's eyes widened in surprise as the person she had been dying to see suddenly strolled through the door.

Much to the pleasant surprise and delight of Fred and George, their second eldest brother walked straight their door, confirming their suspicions that something more had indeed blossomed between the dragon tamer and the bookworm. To make it even better Hermione let out a high pitched squeak as she tried to cover hair.

Charlie was certainly glad to be home, it had been a tiring few weeks at the reserve in Romania after a new batch of eggs decided to hatch early, he was definitely in need of a holiday back home with his family, but what he was more in need of was getting to spend some more time with the young witch that had captivated his attention, so much so that he had a number of fresh new burns on his arms. But as he walked into the kitchen he didn't expect to be greeted by a green and gold haired Ginny and his girlfriend trying to hide her hair in embarrassment, he shouldn't have been so surprised though when he also found the twins sitting at the table in a fit of laughter

"What the hell is going on here?" Charlie strode towards Hermione, giving her a knowing smile as he tried to get a good look at her hair.

"Welcome home Charlie!" George greeted

"You're just in time..." Fred continued

"To witness our new product"

Charlie sighed, "What is it this time?"

"Well we came up with a new potion that can be mixed with shampoo or conditioner, you simple pour a little bit in, give it a good shake and leave it there for your suspect to use" Fred beamed, proud of their newest achievement.

"Then once they've used it within 10 minutes their hair will change, it can change into a different colour or style. Anything could happen! But what the real interesting thing is" George glanced at Hermione with a twinkle in his eye. "Is that whatever your hair changes into, will morph into the one thing that the person who are with or have a crush on, loves the most"

Hermione groaned, she just wished that the ground would open up and swallow her whole, she should have known that there was more to their prank. And they both clearly knew that there had been something going on with both her and Charlie, if they didn't then they surely knew now considering her hair was in the shape of a dragon's tail.

"Oh really?" Charlie hummed, his eyes darting to Hermione who was still trying to cover her hair, using his handler reflexes he quickly pulled Hermione's arms down, although he done this quite gently, to find that her hair had turned a bright orange and was in the shape of a dragon's tail. Charlie could feel his own face growing hot as he took it in, it was only a moment before a wide smile spread across his features.

"Wow" Charlie grinned, slowly turning Hermione on the spot so he could get a good look at her hair. "You really suit this Mione"

Hermione rolled her eyes and slapped his arm playfully, "No I don't" She pouted before turning back to the twins. "Can you please reverse it?"

Fred shook his head, "No can do! The potion has to wear off itself, should be...in an hour or so"

"An hour!" Hermione yelled before shoving her face into Charlie's chest, trying to take deep and calming breaths.

"You can't seriously tell us to stick this for an hour" Ginny whined

"You can't stick what?" Harry asked

In all the hustle and bustle of Charlie arriving and finding out about the twins latest prank, no one had heard the floo activating again and they definitely didn't notice the raven haired wizard entering the kitchen and being surprised to find his own girlfriend with green hair decorated with golden snitches.

"Don't look Harry! I'm hideous" Ginny tried to hide, but Harry being the quick one he is, gently grabbed her hand to stop her from running off, he drank the sight of her in before smiling and placing a sweet kiss to her forehead.

"Ginny, you can never look hideous. Plus, I kind of like the snitches" Harry smiled, raising a hand to softly stroke a stand of hair that a glimmer of snitch on it. Ginny blushed furiously, with one last glare at her brothers and an apologetic look at Hermione, she grabbed her boyfriends hand and disappeared into the living room.

"See Gred, our work here is done" George sighed happily before finishing off his coffee

"Too right, Forge, too right" Fred raised his cup in cheers before draining the last of his coffee.

As the twins stood to leave they both stared knowingly at Hermione and Charlie with knowing smiles, "We always thought something was up between you two. I don't think I can count how many times Hermione has been to visit you in Romania these last few weeks, Charlie"

Hermione flushed, and there she thought she had been discreet.

"Not to mention the very...adult letter she had sent you too" George grinned

Both Charlie and Hermione blushed once again, "How did you even see that!"

"That is why you shouldn't send Errol with the post Granger" Fred teased, "He sometimes gets mixed up with address'. I hadn't been paying attention to who it was addressed too so I just opened it up and began to read it. Who knew you had such an imagination"

"I...I..." Hermione tried to explain herself but for once in her life, she was at a loss for words.

Charlie chuckled and wrapped an arm around her waist, "You don't need to tell them anything love, they're just messing with you"

"I know but it's embarrassing!" Hermione sighed, turning her attention to the twins who were now standing and putting on their travelling cloaks. "If you two ever pull something like this again I will gladly use a bat bogey hex on you both"

"Aye Aye Miss Granger!" George saluted, making Hermione laugh

The twins gathered their belongings and pulled on their cloaks, "Sadly we must take our leave. Work beckons of course, but we'll be back later so don't miss us too much!"

"Oh we won't" Charlie grinned, throwing a wink in Hermione's direction and for what seemed like the hundredth time that day, she turned red.

Feeling slightly uncomfortable now after seeing their brother openly trying to seduce the young witch they called their sister, the twins took their leave but not without getting their last say.

"Don't do anything we wouldn't do!"

"And use protection!"

Once they heard the sound of the fire burning and then going quiet Hermione was finally able to relax, with a smirk that could rival Draco Malfoy's she turned to her boyfriend. "I have an idea"

Charlie grinned, sensing the prankster in her coming out to play. "Oh really? And what might that be?"

"Revenge"
