Yay! There I was worrying this chapter would be too short and it turned into one of the longest ones, even if it is way different then how it had been in my head. Enjoy!

"What are you three doing here?" Fred asked, making Harry, Ron and Hermione leap away from the door leading to the out of bounds corridor, looking guilty.

"You guys really aren't good at this sneaking around stuff," George pointed out.

"But glad to see Hermione having some fun," Fred finished, Hermione scowled at them.

"What about you?" she demanded, "What are you two doing here?"

"Nothing much," George shrugged, Fred discretely tucked the Marauders map out of sight.

"Anyway, you really should leave this alone," Fred said seriously, "There's way better stuff to do than lurk around random corridors."

"I still maintain that I'm not going into the forest with you, that's been the same since first year," Katherine announced, coming up to the group, "Hello you three, what are we all doing here?"

"Fred and George were telling us we shouldn't be here," Ron replied in a bemused voice.

"Well, they're right you know, you really shouldn't hang around here," Katherine sighed, "Anyway, I just ran into Angelina, apparently Katie wants to talk to us about something."

"Oh, what is it?" Fred asked curiously, Harry, Hermione and Ron all just stared at them.

"I don't know, I had to come find you two didn't I?" Katherine huffed, "Which, you know, would be far easier if you stayed put after you spoke to me."

"We'll keep that in mind," George nodded, "So, where were the others headed?"

"C'mon, let's go then," Katherine suggested, then turned to look at the other three, "You lot stay out of trouble, wouldn't want Gryffindor's brightest witch doing something stupid would we?"

She winked at Hermione, who blushed and smiled at the complement.

"You really think she's Gryffindor's smartest witch?" Fred asked sceptically, the other three were already out of hearing distance.

"She'd be pretty close," Katherine nodded, "I mean, I doubt she'd be a match for a seventh year, but she's the top of her class and I imagine if we were in the same year she'd easily be a head of most of us."

"Aren't you drawing yourself a little short?" George asked, raising an eyebrow.

"Hardly, Hermione and I study differently, she's actually a far better student than I am," Katherine shrugged, then she reached over and tugged the Marauder map from Fred's pocket, "I'm borrowing this, you seem under the mistaken impression I'm actually fully aware of where the others are."

"Could've just asked," Fred grumbled, Katherine smirked at him.

"Yes, but where's the fun in that?" she asked.

"Don't mock me," Fred commanded, watching her with narrowed eyes.

"But I wonder what they were doing there," George said thoughtfully as Katherine poked her tongue at Fred.

"That's a good point," Fred nodded.

"You don't think they want to get in do you?"

"Doubt Ron's that stupid."

"They know something's in there."

"Obviously, they were listening to it growling."

"Do you think they know-"

"-why it's there? Nah."

"Doesn't seem unlikely."

"Should we ask?"

"Nah, they weren't too eager to share."

"True, wonder what they've been up to all year."

"Wonder if we're gonna have some competition."

"So, this is what life would have been like if I wasn't around," Katherine announced, getting mildly worried about the excitement in their voices, "I can see why people would get confused by the two of you."

"Who's who?" the twins demanded immediately, Katherine sighed. She wasn't sure why they'd started doing that, but she had her suspicions that Lee had said something that put the idea in there head.

"This one's George," she said easily, throwing her arm over George's shoulder.

"How can you tell I'm not George?" Fred pouted. Katherine raised an eyebrow, then sighed.

"Ok, stop and stand next to each other," she commanded, stepping forward and turning to face them. Both the boys did what she said, identical looks of confusion and curiosity on their faces, "'Kay, now watch."

With that she reached up and ruffled both the boys' hair. She immediately had to dodge as Fred tried to ruffle her hair in retribution, George on the other hand just reached up to flatten his own hair back into place.

"Ta da!" Katherine announced, easily dodging out of Fred's way with practised skill, "And thus you two are different!"

"That's cheating," Fred whined, Katherine twisted out of his way as he tried to mess up her hair again.

"What are friends for?" she shrugged, "C'mon, the others will be wondering where we got to."

"You're so mean," Fred whined, Katherine ignored him in favour of staring at the map.

"What took you so long?" Katie demanded when the three off them pushed through the door, Fred tucking the map back into his pocket.

"Fred and George were being difficult," Katherine replied, "And I hate to be the one to bring it up, but isn't this the room we played truth or dare in last year?"

"It is?" Fred and George asked, looking around.

"Yes it is," Katie nodded, "I'm naming it our business room. We're getting closer to the end of the year so this is the last chance to change your bets on Quirrel."

"Oh, ok then," Katherine nodded, "But all the money bags are still up in my trunk."

Katherine was the unofficial bet holder for the 'Defence teacher bets' as it's been officially named by the group. This was because she refused to take part in trying to work out what terrible event would befall their teacher, also very rarely did anyone want to bet against her, so when they'd originally made all their bets over the severity of how Quirrel would end the year they'd all just handed her the money they were putting on it.

"You just leave it in your trunk?" Lee asked sceptically, raising an eyebrow.

"Her locking charms are ridiculous," Alicia answered for Katherine.

"True story" George nodded.

"She even defends against lock picking," Fred added.

"Do I want to know why you all know the extent of my security?" Katherine asked, narrowing her eyes at the twins.

"You have a biting sketch pad," Fred pointed out defensively.

"It's almost like you don't trust us," George smirked.

"And for good reason," Katherine smirked right back, "Now, is anyone changing their bet?"

Fred and George looked at each other thoughtfully, and everyone else stared into space for a movement before Lee spoke up.

"I think I'm good with mine," he shrugged.

"Yeah, I'm sticking to what I've got," Katie nodded.

"Well, I haven't got any better ideas," Angelina said.

"Neither, I'm good," Alicia agreed.

"We want to change our bet!" Fred and George announced, Katherine raised an eyebrow.

"Ok, shoot," Katherine shrugged, it was always interesting to see the bets the twins made.

"We bet that, whatever it is that happens to Quirrel, it will have something to do with Harry," Fred announced, everyone frowned at him in confusion. Except George, who'd been in on it, and Katherine who had given up on being surprised by the twins' years ago.

"Does everyone think that is an acceptable bet?" she asked, looking around at the others, and chuckling at their various levels of confusion.

"I don't, does that even count?" Lee asked, turning to Katherine.

"According to what you all agreed on your allowed to bet on the severity or any major factors, so yes, assuming you all approve it their allowed to use that bet," Katherine nodded thoughtfully.

"Ok, fine I accept it," Alicia sighed, "But can we leave now, we should've just done this in the Common room."

"No, people get suspicious when we all huddle together in the Common room," Lee argued, "And I agree too."

"Yep, I'm up for it," Angelina nodded, ignoring the minor argument between Lee and Alicia.

"Well, I think that they know something we don't and, therefore, it's unfair," Katie announced, "But it's within the rules and everyone else has already approved it so, I guess it's only fair to let them."

Fred and George grinned widely as Katherine nodded and everyone began collecting their things.

"Hey, Katie," Katherine called matching pace with the younger girl as the twins talked with Lee, "Can we have a little more warning next time?"

"Why?" Katie asked immediately, nosy little thing that she was, "You were off drawing somewhere you didn't want the twins finding you weren't you?"

"The twins know the castle more than you seem to give them credit for," Katherine replied, easily dodging around the question.

"Maybe, but a take your lack of direct answer to mean I'm right," Katie shrugged, Katherine frowned at her, "What? Just because other people haven't caught on to how you avoid lying doesn't mean everyone's missed it."

"You suck," Katherine sighed because, yes, she had been drawing and hadn't wanted the twins to find her. She loved her little alcove, and usually nicked the map when she was going there. It was just so peaceful, she loved hanging out with the twins, but it was nice to have a quiet place to relax sometimes. Somewhere that wasn't the library.

That aside she'd just been doing vague animal sketches, something she'd taken to doing even though she was pretty sure her actual Animagus transformation was still ages away. They were like copies of some of the drawings she'd seen as well a few sketches of different animals. The first transformations didn't look or sound fun, but after that it came naturally so she wasn't too worried.

"Whatever you say, so can I see what you were drawing?" Katie asked.

"No, you're nosy and you Merlin only knows how you have half the information you have," Katherine replied, rolling her eyes.

"Well, that's hardly fair, on the other hand you help me with homework so I'm not going to push it."

"I'm glad our friendship means so much to you," Katherine chuckled.

"What are you two talking about?" Fred asked, throwing an arm over Katherine's shoulders.

"Ow," Katherine protested, pushing Fred off her, "Quit using me as your armrest."

"But Katty, you're so good at it," Fred teased, Katherine raised an eyebrow.

"You know I've been doing really well in Transfiguration lately," she smirked, "Wanna see how you'd do as an arm rest?"

Katie laughed as Fred made a face. She, Angelina, Alicia, George and Lee all laughed as the two of the threw random little transfiguration threats at each other as they continued towards the Common room.

"You know," Angelina said after a moment, "They are actually both really good at transfiguration, I wonder if we should be worried."

"Nah," George replied with a grin, "Fred wouldn't do anything that could hurt her, sides, if Katherine was actually annoyed at him she'd just jinx him."

"I love it how Fred wouldn't hurt her but she'd just jinx him," Angelina laughed.

"Oh, she wouldn't seriously hurt him either," Katie shrugged, easily joining in the conversation, "It's just more natural to her to bring out her wand when someone's being a nuisance, besides she's jinxed him before and he's fine."

Fred proceeded to walk into a fake door because he wasn't looking where he was going and the whole group laughed as he grumbled about distracting arguments and magic walls.

"Well, maybe not absolutely fine, huh Ang?" George chuckled, Angelina nodded in agreement, smiling easily at him as her own laughter subsided.

"Have you noticed how Ron and Harry have been acting around Quirrel?"

"Have you noticed how ever since you caught them outside the third floor corridor you've been obsessing over every little thing they do?"

"No, really Kat, it's weird, they're being like, super nice to him."

"George, if they want to suck up to a teacher let them be, and Fred, I know what you're thinking and if you pull that map out to go stalking after them, again, I am going to steal it and hide it somewhere in the castle and you'll never see it again."

Fred looked up in horror at this threat, only to look more horrified as he saw that Katherine looked totally serious about this.

"No way," he gaped, "You wouldn't do that."

"Maybe I would," Katherine argued, pointing her pencil at him, "Do you really want to risk it?"

"Your evil," Fred said decidedly, "And homework's boring."

"Sucks to be you," Katherine shrugged, returning to her sketches, "You should have got it all finished earlier. Also you put Jupiter in the wrong position on your star chart."

"So, what you drawing?" George asked, leaning over to see that she was sketching them doing their homework, he raised an eyebrow.

"What?" Katherine asked, holding the book up to get a better look at it, "It looks fine, you should see what happened to the one I was working on when Lee ran in the other day, it was hilarious, Lee just became this huge blur in the doorway."

"Wait, you draw us regularly," George questioned, looking slightly confused.

"Sure, I used to draw Theodore and my mum all the time too," Katherine shrugged, "Now I draw you two, why? Do you dislike me drawing you?"

"Not at all," George replied, "I just didn't realise you drew us so often, and did you just compare us to your family."

"Yeah, but don't worry, only the good part. Though I do have some sketches of my dad, I never drew him as often."

"Will we ever get to see any of these?"

"Probably not, but who knows."

"Ok, is that better?" Fred demanded, holding up his star chart. Katherine and George stared at him for a moment before Katherine turned her attention to the star chart.

"Excellent, except you now have two planets of mars and I don't even know what's up with this clump of stars," she informed him. He looked at the clump of stars and snorted.

"They're not stars, that was from when we were having the ink fight with Lee," he informed her, pulling out his wand to clean up the mess.

"You two are insane," Katherine said after a moment, smiling fondly as Fred worked on trying to fix the star chart.

"Yep, apparently they were spreading a rumour about a dragon," Lee nodded seriously.

"Yeah, but in the Forbidden Forest?" Fred asked sceptically, "We've never even been given punishment in there, and this was their first time getting caught, right?"

"Yeah, and the only thing they could be pegged for was being out after curfew," George added, munching on his breakfast.

Harry looked haggard at breakfast, apparently he hadn't slept much. Ron and Hermione looked a little better but they all looked like they had some dark secret.

"Hagrid needed help in the forest," Katherine shrugged, "It was just a bad time to get caught."

"Why are you always coming up with reasonable explanations when exciting stuff is going on?" Fred whined.

"Because it's none of your business, anyway Neville and Malfoy were with them, no doubt Malfoy was just being a prat and they all got a little freaked out," Katherine said sensibley, then she chuckled, "Besides, going into the forest would hardly have been a punishment for you, would it?"

"Not really, but it would've been cool," Fred replied, flicking some food at her. She dodged it easily, only to have it hit Lee, who tossed some at George. Katherine slipped away from them as it turned into an all-out food fight, only to bump into Hermione as she, Harry and Ron were leaving the hall.

"Hey," she greeted them with a smile, "Bad night last night?"

"You could say that," Hermione sighed, rubbing her face.

"But I'm sure whatever you got the detention for was important right?" Katherine asked, then laughed at their guilty expressions, "You don't have to tell me what it was, I'm not looking to get you in more trouble."

"Things just ended up a little more serious in the forest last night, not the nicest place on Earth," Hermione explained, Harry nodded in agreement, rubbing his scar.

"I'd imagine not," Katherine smiled, "But stay out of trouble and now all you've got to worry about are exams."

"Merlin I'd forgotten about those," Ron groaned, Hermione gave him a scandalised look and Katherine bit back a chuckle. Harry just looked resigned to the argument that looked like it was about to start.

"Well, you three should go study," she advised, "McGonagall looks annoyed, I gotta get Fred, George and Lee to calm down."

The other three nodded and headed out of the hall. Katherine turned to see that the fight had escalated and apparently the three boys had pulled their wand at some point. Many other student where holding up trays, plates and books as shields against the food. Taking a deep breathe Katherine put her fingers in her mouth and released an ear splitting whistle. There was clattering in the hall as many people dropped what they were holding to cover their ears.

The hall turned to star at her and Fred seemed to suddenly remember why he'd started throwing food and stood up, George followed suit and soon the three of them were racing down the halls. Katherine slowed down every now and then, knowing that she was faster than her friends, but eventually they made it out onto the grounds.

"You cheated!" Fred announced, after the twins had caught up with her at the other side of the lake.

"We weren't playing a game," Katherine pointed out, "There were no rules."

"You still cheated!" Fred snapped, then collapsed backwards onto the grass, "Merlin I'm exhausted, screw it, the weathers nice. I'm staying here!"

"I'm glad we have the same idea," Katherine grinned, George chuckled as he sat himself on the grass as well.

"Katty," Fred whined, throwing and arm over his eyes to block out the light.

Moments later Fred was asleep and, if he woke up with little drawings all over his face? Well, Katherine and George had nothing to do with it.

"I still can't believe we had to forfeit the Quidditch match!" Alicia whined, slumping on the couch.

"Well, Harry is in the hospital wing, and unconscious for that matter," Katherine pointed out with a sigh.

"Why couldn't he go nearly get himself killed after the match?"

"Alicia, think first and then let yourself talk."

"Ok, so that's uncalled for, but we were so close."

"I know," Katherine sighed, "I have not heard the end of it. I'm finally away from the constant whining of the twins and I'm stuck with your whining."

"Where are the twins?" Angelina asked curiously, Katherine shrugged.

"They said something about Harry needing a present more than Ginny, then they ran off," she replied, "They looked like they were plotting something big, I decided to leave them alone."

"Really?" Katie asked, "That doesn't sound like you."

"Yeah, I wonder what they plan on giving Harry anyway," Alicia said thoughtfully, "Especially if they were going to give it to Ginny first."

Katherine suddenly sat bolt upright, looking horrified and disbelieving.

"There's no way," she mumbled, "They wouldn't…"

"Wouldn't what?" Angelina asked.

"I have to go," Katherine announced, pulling the map from Fred's bag before rocketing out of the room.

"I guess she worked out what they were up to," Katie suggested, looking at the other two girls as though they'd have a better explanation. Both the older girls just shrugged, used to having no idea what was going on with their friends.

…

"Ready, Fred?"

"Ready, George!"

"Five, four, three-"

BOOM!

The twins' countdown was interrupted by a huge explosion, gushing water and the distinctive wailing of one Moaning Myrtle. The twin stared in awe at the fountain of water that had previously been a toilet.

"Your explosion was a bit premature," a voice announced from behind them. The twins turned, doing nothing to hide their excitement as they grinned widely at Katherine, who couldn't help her own grin and, within moments, they were all laughing hysterically.

"I can't, believe, you, blew up a toilet!" Katherine gasped, leaning on one of the walls to keep herself off the flooded floor.

"It was mum's idea," Fred replied, laughter finally fading.

"Yeah, but don't tell her that," George added thoughtfully.

"Oh yes, it's so funny to blow up Myrtle's bathroom, Myrtle doesn't matter, she's DEAD!" Myrtle screamed, flying up one of the toilets.

"Oh, cheer up Myrtle," Fred commanded, "You went even here when we started."

"Yeah, and it's not like we blew up your toilet," George pointed out.

"Sides, really we just wanted…this!" Fred announced, triumphantly holding up the toilet seat.

"Sweet, let's get out of here, sorry to intrude Myrtle," George said, waving as the trio left the bathroom.

"My shoes are soaked," Katherine announced as they stepped out of the bathroom, and she snorted at the sight, "You flooded the whole hall."

"Oh well, Myrtle does it all the time," Fred shrugged, and George continued for him, "The teachers will just think Peeves was picking on her again or something like that."

"Your far too relaxed about this," Katherine informed them with a sigh, "And how are you planning to get that to Harry anyway?"

"Madam Pomfrey allows presents," Fred replied, swinging the toilet seat around as though it was a usual toy, Katherine rolled her eyes.

"I doubt it'll be that simple," she sighed.

"Only one way to find out," George shrugged, "C'mon we're almost at the hospital wing."

"Hey Poppy," Fred greeted as they walked in, Madam Pomfrey scowled at him.

"What are you boys doing here, you haven't hurt yourselves again I hope," she said quickly looking them over, she seemed to visibly relax when she found they were uninjured, "Well, at least keep it down, this is a hospital you know."

"Of course Poppy," Fred nodded, "We just came to give Harry a present."

"Oh, well that is sweet, poor boy's in awful shape, still hasn't woken up you know."

Fred and George nodded solemnly at this news, Fred was hiding the toilet seat behind his back. Katherine stood against one of the walls, just watching because she didn't want to be involved when Madam Pomfrey realised what was going on.

"So, what did you bring him?" Pomfrey asked reasonably. Fred and George exchanged a look, and Katherine smirked as she saw excuses and lies forming.

…

"Absolutely not! It's insanitary, now shoo, all of you," Pomfrey scolded, shooing the three Gryffindors out of the Hospital. She'd confiscated the toilet seat and spent a fair while scolding the twins while Katherine snickered in the back ground. The twins had, of course, tried to argue their case and had ended up with a rather put-out Healer shooing them away.

"Well, that went well," Katherine smirked.

"You know what they say, it's the thought that counts," George shrugged, Katherine rolled her eyes.

"I'm not exactly sure a toilet seat is the greatest get well message," she pointed out.

"Maybe not," Fred conceded, "But if you woke up and found a toilet seat just sitting there, how hilarious would that be?"

"I think he'd more confused than amused Fred, he's not use to your antics."

"Oh well, it was still fun blowing up that toilet."

Staff Room Chats

"I can't believe they blew up a toilet," McGonagall groaned putting her face in her hands.

"They are a lively pair aren't they?" Professor Sprout chuckled, "Did you get it fixed, though?"

"We did," Flitwick nodded, smiling amusedly, "Though it didn't help that Myrtle kept swooping around crying about her spots and how no one cares about her because she's dead."

"Really, I was under the impression it was because all she did was complain," Snape smirked.

"Severus," McGonagall scolded then sighed again, "I don't think I'll make it through the next seven years if this keeps up. The Weasley twins were bad enough but Potter and his friends…"

"They do seem to have a knack for finding trouble don't they?" Sprout smiled, idly flick her wand to make some of the flowers she'd placed in the room come into bloom, "I'm amazed at Miss Granger personally."

"Very true," McGonagall nodded, "With their family track records I was prepared for trouble from Potter and Weasley but Miss Ganger, well, I guess she proved how loyal she is to her friends at least."

"She is an amazing student though," Flitwick pointed out, "It's hard to fault her on anything in class."

"Quite the prodigy," McGonagall nodded with a sigh, "She reminds me a bit of Lily."

"Indeed," Flitwick nodded solemnly.

"Sharpest witches of their age, and Muggle-born too," Sprout said seriously, "If there's any proof against the lies You-Know-Who spread those two are it."

Solemn silence fell across the Heads of house as they remembered Lily and all the suffering Voldemort had caused. Even this year, Dumbledore had given them a brief idea of what had happened, how close he'd been to regaining power.

"A shame he could not have stayed wherever he's been hidden the last ten years," Flitwick sighed.

"Do you suppose he's gone for good this time, Minerva?" Sprout asked with false hope.

"I fear not," McGonagall replied, "And I fear Potter will not have the most controlled school years, if this year was anything to judge on."

"Ah, what a solemn mood," Dumbledore greeted, casually strolling into the room, "Everyone needs to cheer up a bit, term is almost over, we should be happily awaiting the coming holidays. I, myself, just went to visit Mr Potter and he appears in fine health, quite eager to get out of bed in fact. I think we should all take a leaf from his book and enjoy the last few days of school."

There was a range of 'yes, Albus's as the Professors filtered from the room to take care of various thing. After a moment Dumbledore and McGonagall were the only ones left, McGonagall considered asking more about what had happened, but decided against it.

"Albus, did you hear about the mess in Myrtle's bathroom?" She asked instead, Dumbledore smiled slightly.

"Indeed I did, sadly we have no evidence as to who did it, just another mystery of the castle," he sighed, his eyes filled with laughter.

"Really Albus? You think it wise to do nothing?" McGonagall scowled.

"No one was hurt, and it was all in good fun, Minerva," Dumbledore replied, "Now come, the house elves have prepared some excellent food for tonight's feast, I would not want to miss it."

"Of course Albus," McGonagall sighed. Well, at least she didn't have to write to Molly Weasley. Again.

"Katty what you doing?"

"I'm Just saying hi to your mum Fred, relax," Katherine commanded, smiling with Mrs Weasley as the twins walked up.

"Hey Katherine," Ginny greeted, smiling up at the older girl.

"Hey Ginny," Katherine smirked, ruffling the girls' hair, "Finished freaking out over Harry Potter?"

Ginny blushed and the twins laughed from behind Katherine. Ginny scowled at them but Katherine just rolled her eyes. Harry and his family had already left and she was just saying goodbye to the Weasley's before she went to find Theodore.

"Anyway, I have to go guys," Katherine said, giving Ginny and each of the twins a hug before she wandered off with a wave, "See you, don't cause to much trouble guys."

"Us, trouble?" George asked.

"We've no idea what you're talking about," Fred said, sounding offended. Katherine just laughed and wandered off to find Theodore.

"Katty!" Katherine turned to the voice, smiling as her brother came up to join her.

"Hey Theo, how you doing?" she asked, smiling as they searched for their father.

"Fine, I think I'm going to ask father if I can go to Blaise's house these holidays," he replied thoughtfully, "I'd rather that than the Malfoy's at any rate."

"Not really a hard choice is it?" Katherine chuckled, "But it would be good, and we can just say it'd be easier for his business."

"Theodore, I'm glad to see you did well in your classes," was their fathers greeting, "I trust you had a productive year."

"Of course father, and I was wondering if perhaps I could spend some time this Summer at the Zabini's?" Theodore replied, and it was easy to tell the difference between how they spoke to each other and how they spoke in front of their father.

"Well, I am pleased to see you have found respectable company," Mr Nott said thoughtfully, "But I'm not sure if that is in our best interest."

Katherine caught his yes flick towards her and hid a frown behind her emotionless mask. It was clear he just didn't want to be stuck with her for the Summer, she was, after all, horrible Gryffindor company.

"I can stay with the Weasley's, father," she offered emotionlessly, "If it would be more convenient for you."

"Well, then we shall see," he said after a moment, "Now come, I have work to do."

Theodore winked at Katherine before the side along apparated. Now they both had a chance to spend the Summer with their friends. Katherine grinned, she'd love to stay at the Burrow again.

So, everyone hating Katherine's dad? So, I was wondering if anyone wanted to give their thoughts on Katherine's Animagus form, it'd be interesting to see what you all think she's going to be.
Anyway, hope you enjoyed! R&R!
