Disclaimer: I obviously don't own Harry Potter! Beta'd by my wonderful better half.

Blond hair was slicked back and calculating blue eyes watched his rival, the teen's potion was bubbling dangerously even without him having to resort to sabotage. His lips twitched with a smirk as he swaggered over towards the store cupboard, pausing as always to sneer at his rival. So intent on getting a rise from the angry boy that he didn't see the movement of Crabbe throwing an ingredient. In fact neither of them reacted until too late, the potion surface bubbled dangerously before erupting both boys taking a face full of the shimmering golden concoction.

Harry groaned, forcing his eyes to stay open even as the bright light nearly blinded him. Pure white ceiling…the hospital wing. He tried to push himself up, falling back with a sigh as nausea overwhelmed him. He groped blindly for his glasses, breathing heavily as he tried to calm his mutinous stomach. He felt weird.

"Ah good! You're awake. How are you feeling Mr Potter?" A blurry Madam Pomfrey came into view. Harry grumbled resuming his search for his glasses, even as the blurry Nurse pressed them into his hand.

"What happened?" They came out more jumbled than he'd intended and his own words seemed to take an eternity to sink through the mass of cotton in his head. "Weird. I feel weird."

"The Headmaster is on his way over, he wished to be informed the instant that you or young Mr Malfoy woke." She smiled kindly, tucking him in again, "Try not to push yourself too much, you've had quite the shock and your body is still… recovering." Harry was thankful for his glasses as at least one thing seemed normal even though he couldn't see his rival who Harry was certain had something to do with his current situation. Hopeful that Dumbledore could shed some light on his situation, he found his eyes slipping closed again the instant the stern matron had bustled off.

When he woke again it was too loud, irritated, and above all, high pitched shouting in a tone that could only belong to his accursed rival. The moron who had gotten him into this mess. Harry gingerly pushed himself up, swinging his legs over the side and standing before his body could protest. He stumbled slightly as his body tried to adjust to the change in gravity and he frowned as his head spun. Following the shouting wasn't difficult even if walking did require him leaning on the beds that he passed and was slower going than he'd have preferred.

"For Merlin's sake. Shut the fu-" He stopped the instant he'd pushed his way through the curtains and actually saw his rival…

Draco scowled as Potter started yelling, pushing his hair out of his face, however long he'd been unconscious had apparently been long enough for the gel to have been washed out, although judging from the horrible hospital robes that the pair of them were wearing it had apparently been the case for both of them.

"Come to rub in what your potion did to me?" He asked sneering, "Although," He smirked, "looks like I wasn't the only one effected." Potter scowled, either he was as dense as he was obtuse, or he was still out of it, and had yet to realise. Madam Pomfrey was looking between the two of them with a concerned frown, she looked one step away from forcing them back to bed and probably sending them to sleep.

"What are you talking about?!" Potter finally snapped and shouted.

"Clearly you didn't have anything to write home about," he was unable to resist the dig, "but I'd have thought even you would have noticed that you're missing something." He laughed even as his rival launched himself at him. Potter didn't manage to get more than one punch in before he was levitated away from him by a furious Matron, even so he was still struggling to get towards his laughing rival.

Light blue eyes narrowed as she stared at the elderly Wizard before her. "What do you mean there's been an incident?" Her aristocratic voice held distain and fury, yet through that the worry for her son shone through. "Is my son alright?! And why have you not called my husband as well?" she snapped.

She might have continued on with her tirade had it not been for the stately wizard holding up his hand, "Mrs Malfoy, if you would allow me to explain I will tell you both." He smiled grandfatherly at Mrs Weasley who was stood beside the furious blonde, while she was far more reserved, in that she was allowing him to explain, however her expression told him that she also was growing angrier. "The potions accident which happened seems to have had a result that I have never seen in all my years. Young Mr Malfoy and Young Mr Potter seem to have changed gender, unfortunately Professor Snape does not believe that it is reversible." He paused, his expression softening, "The two are still in the hospital wing, Madam Pomfrey suggested that it would be better for you both to tell them than for it to be coming from one of their Professors."

Narcissa scowled, heading towards the door, Molly paused for a moment before following like the younger mother she didn't look particularly impressed with him either. Dumbledore frowned after the two, letting out a particularly weary sigh as the door banged.

Several corridors passed before Narcissa asked the question which had been on the tip of her tongue since she'd heard the identity of the other student, having assumed that it was one of her many children. "Why did Professor Dumbledore not call Mr Potter's relatives?" Her tone was softer than Molly had expected, concern evident in her face.

"…" Molly paused, frowning to herself. "Harry's relatives…" she stopped herself again, wondering how to phrase her thoughts, "They're not the most desirable people," her lip curled slightly, "the stories I've heard!" She scowled, "Honestly! The gall of some people! I dread to think what they'll do-"she stopped herself, remembering suddenly who she was speaking to.

However her companion's eyes narrowed to abject fury, "No child should be treated like that!" She'd been able to fill in the blanks in what the elder woman had said, "Surely the Headmaster will allow you to take the child?" Her brows furrowed, clearly thinking about the situation, she'd never understood her husband's feud with Mr Weasley and frankly with the current issue saw the other as an ally. "The children will probably need each other, even if they don't particularly like each other." She thought quickly, "They'll need someone who can understand exactly what they're going through."

Molly nodded, seeing the olive branch that was being offered and taking it with both hands. "That sounds like a good plan." She smiled at the other woman, as they pushed the door to the hospital wing, her jaw dropped at the sight of the struggling Harry being held up by a long suffering Madam Pomfrey. "GIRLS!" She yelled a few decibels louder than Narcissa's own shout.

Both teens froze seeing the enraged mothers standing in the doorway, "He started it!" they said as one.

A flick of Madam Pomfrey's wand had the now cowed black haired child put into the adjacent bed, Molly was at Harry's side in an instant, before the younger could move towards her rival. "Enough Harry." Her tone broached no arguments and Draco's sneering response was cut off by Narcissa's own disapproval.

"Madam, are the changes complete?" She didn't particularly want to spell it out fully to the girls yet, "are they expected to go through that time of the month?"

The Matron nodded, a soft expression on her face as she looked at the two teens. "Perhaps it would be better for them to be taken home so that you can explain to them properly." She added softly "they're in no danger as it stands."

Molly and Narcissa shared a look before the blonde spoke, "Your house? It might be better to only do this once." Molly nodded and the two flicked their wands.

Arthur scowled at the mess of paper work on his desk, scooping up a few of the papers which were required for the meeting. His scowl only deepened as he recalled that Malfoy would be in the meeting, with a sigh he rose and headed towards the conference room.

He'd barely entered and exchanged snide greetings with the pompous blond when two patronus' appeared before them, he didn't know the owner of the gracious swan which approached Malfoy however his heart was in his mouth as Molly's bear bounded over to him. "Arthur, dear, I need you to head home, we'll meet you there. There's been a potions accident." His mind ran quickly through all the possibilities and hoped to goodness that all the kids were alright, the worst scenarios were pushed aside only by the lack of panic and grief in Molly's voice. He was brought back to reality by the sound of Narcissa's voice coming from the other patronus "Lucius, meet us at the Weasley's house, there's been a potions accident, Draco is physically alright however…well I'll explain when we see you."

Both of their eyes narrowed as they were excused "What has your son done this time?!" They said at the same time, scowling as they bickered their way towards the floo.

Molly scowled at the men who sat in mutinous silence at the dining table. "Arthur! Have you not offered Mr Malfoy a cup of tea?!" She bustled over to the hob the kettle already filling with water. "Tea will do all of us some good." She nodded over to the fire where by now Narcissa was ushering two teens over to the table.

"That would be wonderful," Narcissa smiled, "Thank you Molly." The two teens were still scowling at each other, but neither spoke as they were pushed to sit next to the respective male.

Tea floated over, resting before each person, the Mothers exchanged looks as the floo sounded again. Professor Dumbledore stepped through, brushing non-existent ash off of his purple robes, followed quickly by a glowering Potions Master. Both Mothers exchanged a relieved look, neither of them had been sure where to begin.

"Ah! You're all together!" Dumbledore smiled as though he hadn't been aware of the situation before flooing straight into the Burrow's kitchen. "Severus! Perhaps you would like to explain your findings!"

The dower man looked if anything grumpier, "It appears that the potion was sabotaged, despite that, even Potter's incompetence shouldn't have managed something of this magnitude. However…" he sighed furious that the Headmaster and Potter had put him into this position, "it appears that changing their genders wasn't all that the potion did."

The sound of shattering crockery, smashed through their shock, Harry stared at Draco and Draco stared back. Somehow in the dishevel neither of the particularly dense thirteen year olds had twigged what had happened, both had realised that something had changed with their rival but even the respective shouts hadn't made them realise it included them.

"What potion was it?" The drawl even sounded as though it had a sneer. Lucius was staring at his heir.

"Hair growth potion." Draco scowled, pushing hair out of her face and behind an ear. Harry's staring was really starting to do her head in and she maturely pulled a face at her rival. Even as the other teen blew hair out of her face, the wild mess staying relatively out of the way, but for the first time all of the adults could see the youngsters' eyes. Molly and Narcissa gasped. Harry's left eye was no longer green just as surely as Draco's left was now that exact shade of green, while Harry seemed to have gained the exact shade of grey blue of Draco's right. Heterochromia was uncommon enough in both worlds but for the clarity and similarity of the two eyes, told both Mothers exactly what Snape was hinting at.

"Indeed." The sneering man continued as though he'd never been interrupted, "The two seem to now share more than just their gender. Its due to this that I highly doubt that it will be possible to ever change them back, although I'm still investigating on that front."

Lucius' eyes narrowed further, his rage almost palpable in the air, he sneered at the assembled group as he rose to his feet. "Then I had better start looking at betrothal contracts, I'm sure that Nott or Zabini will be suitable matches," Draco flinched as though stabbed and Narcissa glared at her husband pulling her daughter towards her. "I'll need another Heir of course," He gestured to his wife to follow him, ignoring the way his child's eyes filled with tears.

"Get out." Narcissa snapped, Lucius looked taken aback for a moment, magic was already pushing him towards the floo. Her eyes narrowed dangerously, he'd never seen her this angry and in that instant he recalled exactly who her sister was. Blacks had long had a reputation which none wished to mess with, just because Narcissa had always been far calmer and reserved didn't mean that she had forgotten the teachings of her family. Something Lucius quickly decided that he didn't want to deal with, especially when he realised that not only was her wand pointed at him but that both the Weasley's looked like if he didn't leave than they'd both curse him as well. Heck he didn't even look as though he had much support from Severus, he glowered as he stormed towards the door.

"You will regret this." He let the door slam as he turned and vanished with a crack.

Draco choked back a sob, raising tearful eyes to her rival who she noticed, with a jolt of shock, that the black haired girl had put herself between the blonde and her father. Now he was gone, she dropped down into his vacant seat. Draco expected a snide response but all she saw was shock and disgust with what the elder Malfoy had done. Narcissa had wrapped her arms around her daughter and now noticing that her crying daughter was clutching her rival.

Dumbledore smiled softly at the drained group, "I think it would be better if we leave, the girls could do with a rest and it might be better if they took a couple of weeks off to get adjusted after all they'll also need to get new uniforms, we will of course arrange for them to have private rooms when they return to ease the change." With the adults nods and the newly turned girls looking overwhelmed he gestured for Severus to leave first before he also flooed away.

Molly smiled at the two children, "I'll go make up a few beds, we can go shopping in tomorrow." She bustled off, aware that Narcissa was too busy comforting her daughter to think of what she needed to do. Harry seemed to be dealing far better, however she was at least used to unexpected happening to her.

Narcissa had visited the Parkinsons' after putting her son turned daughter to bed, it had been a long exhausting conversation upon returning she was relieved to find Molly had the kettle on. The two women had bonded over the hot drinks, Narcissa finding herself reminded strongly of her estranged sister and had felt truly relaxed for the first time in years it seemed to be an effect of the homely building.

As such she was much more optimistic when she got up that morning, smiling as she headed down towards the delightful smell of fresh bread and bacon. Molly was bustling around the kitchen, while Arthur was engrossed in the Prophet which thankfully didn't seem to have picked up the news yet. She'd exchanged greetings and sat down when thudding came from upstairs, Molly had laughed and said that the kids seemed to be awake. The lack of shouting was something the pair of them were thankful of. The thudding coming closer told them that they'd soon have two hungry mouths to feed and before Narcissa could blink, both were sitting down, giving the adults curious looks.

Molly floated full plates over, Harry ate quickly as though it was going to vanish at any moment. Narcissa's eyes narrowed, more evidence against Harry's relatives, not to mention that she'd noticed she looked underweight. Draco ate with no less gusto however she kept glancing at her mum like she'd be told off for her manners.

"We'll head over to Diagon later, go to Gringotts and then go shopping." Molly looked at the two, "Probably get your hair done while we're there," She looked at Narcissa wondering if there was anything the blonde wanted to add.

"You'll both need full new uniforms and of course new wardrobes." She beamed, Draco felt her blood run cold, she'd been put through Narcissa's shopping before and wondered if either of them would survive this. "Have either of you given any thought as to what you want to be called?"

Harry's brow crinkled, "I can stick with Harry right? I mean some girls are called Harry besides that's what I'm used to."

"Same. I want to stick with the same name too." Draco interjected quickly, sure she knew that her mother no doubt had a name in mind, she rather liked her name and had no intention of changing it. Narcissa sighed and nodded, she had no doubt that her child had guessed her thoughts and she was a little disappointed that she wouldn't get to choose a new name but it was after all Draco's choice.

Narcissa had insisted on paying for everything from the Malfoy vaults, removing the need to go to Gringotts as both Mothers were worried that the two girls would be overwhelmed and Narcissa could pay easier with her ring. The pouting teens were helped to dress in resized clothes of Ginny's, neither had been particularly enamoured by learning both how training bra's worked or that they apparently now needed them. Until Narcissa had alleviated that by pointing out that surely they'd previously noticed that some of the girls were growing and the boys liked to talk and stare which had stopped any protested quite quickly.

Madam Malkin's was thankfully empty when the group entered, Narcissa figuring that they'd make a couple of stops. Malkin's for the school clothes and a couple of muggle outfits before heading to Twilfitt and Tatting's for the rest of the girl's clothes. Upon hearing that they'd only be heading to two shops, Harry had naively been relieved while Draco looked like she had been told that she was heading to the executioners block. The two were quickly measured and before the two knew they were lead into the second shop.

Molly was felt out of place, she had after all not been in the upscale clothing store before, and the clothing was clearly better quality. However with Narcissa at her side, two teens to play dress up with and no limit, she soon threw herself into picking out clothing and forcing the increasing surly teens to try it on or hold it up to them. Some colours and fabrics were instantly discarded while others were put to a side, different styles were tested and altered many discarded. Molly soon found herself pressganged into trying a few different ones herself, Narcissa insisting on treating her friend for letting them stay until she'd found a solution to the problem. Before long there was a heap of acceptable clothing, neither of the former boy's saw a reason for them needing so many clothes and Harry was far more overwhelmed, the Dursley's having never bothered with new clothes for her and her own shopping limited to school uniform. She was thankful that Narcissa seemed to have finally decided that it was enough clothing, undergarments had been the most embarrassing part, bras, she decided, were clearly the invention of a particularly evil and cruel Dark Lord.

Harry's stuttered and incessant 'Thank you's to Narcissa gained her, her first true smile from Draco.

Over the following weeks, the two were coached through all of the things they should have known. Including a particularly mortifying talk about protections and how boys might take advantage followed by an explanation on the joys of periods. The latter turned out to be fortuitous as Harry was woken up near the end of their first week to Draco's high pitched screeching, something which Harry's particularly snide mood didn't contend well with. However she discovered the following morning the horror of waking up to find yourself bleeding, she would always maintain that her screaming for one of them was far quieter and no-where near as high pitched. By the time they were to return, the two felt as though they had two Mothers and during the Period issue a rather embarrassed and sheepish Father as well as an annoying twin.

Neither of the teens were sure whether to be delighted or horrified when Molly and Narcissa informed the two that they were escorting them back to school especially given that they had missed two months of school in the end. While they were thankful at the same time they were also weary just of returning, the Burrow was comfortable and homely but at the same time Hogwarts was Hogwarts. Harry was dreading the stares and for once Draco was weary for the same reason, her Father had made it clear what he expected and she was afraid that he'd gone against her Mother. As such the two teens were clinging to their guardians while the Mothers tried to convince the reluctant duo to enter the great hall. Neither noticed their respective friends waiting for their attention as the two managed to hold back tears as they hugged both Mothers sometimes at the same time. "Go on Dears." Molly managed while trying unsuccessfully to pry her limpets off of her, last time she'd managed the duo had attached themselves to Narcissa instead, "Your friends are waiting." The two gave her watery pouts, the best pleading expressions that they could manage, it was only years of having her own children trying the same that allowed her to stand strong and not just sweep the two back to the Burrow.

Ron's confused frown drew his Mothers attention, he didn't understand how come Draco seemed so fond of his mum. Sure, she was awesome, but he didn't get why Malfoy had suddenly come to realise it. Hermione had said something about the two staying together while they were off so perhaps that was what had led to it. That said there was nothing faked about those hugs, in fact he was reminded of the twins something which disturbed him far more than his best mate being turned into a girl.

"Girls." Narcissa spoke softly, "Go on, your friends are standing there waiting for you." The pair slowly released Molly, a clear battle between maternal affection and teenage pride. They exchanged looks, the adults trying to hide their amusement as the blushing teens turned around. Hermione was crossing the entrance hall, Pansy just behind her. The two lit up seeing their respective female friends, Ron gave Harry thumbs up and the ebony haired girl beamed glad that her friends hadn't abandoned her. Molly had told the duo about the break in during Halloween and Harry was relieved that she'd not been there, sleeping in the great hall didn't sound the most comfortable but she was also glad her friends were all alright. Before she could speak her face was full of bushy hair as her apparently still taller friend engulfed her in a crushing hug, Draco was still laughing as Pansy gave her own crushing embrace, although Draco was relieved that she was taller than her oldest friend.

Before they knew it, Harry and Draco were saying their farewells and being pulled into the Great Hall. Hermione and Pansy seemed to have reached an understanding as the two were dragged to the Gryffindor table.

"How are you doing Draco?" Pansy spoke first, "It is still Draco right?"

Draco and Harry exchanged a look and slowly grinned, "Yup!" the blonde took care to pop her 'p'.
"We had that time of the month." Harry spoke conspiratorially.

Hermione's eyes widened, "How was it?" She asked, her own having not come yet.

"Oh it was terrible." Draco started.
"The pain." Harry continued.
"Thought I was going to die,"
"I could have sworn my stomach was being ripped out,"
"and the blood..." the two gave a shudder.
"There was sooooo much of it,"
"Lakes of it..."
"She screamed like a banshee,"
Draco pouted slightly, "Woke the whole house she did,"
"Traumatised Mr Weasley,"

By which time the colour had drained out of the surrounding girls faces. The Gryffindor chasers seemed to have let the cat out of the bag, Harry could see the sniggers on their faces out of the corner of her eyes. Judging from the Weasley twins' expression, someone had let them in on what was so funny.

The duo's fun was broken by the Twins sliding before them on their knees before bowing their heads to the floor the whole while chanting, "We're not worthy, we're not worthy."

Unable to stop themselves, both at the chanting from the twins and the looks of horror on the others' faces, even some of the boys. The duo spoke as one "Your faces." They giggled unable to stop themselves, leaning onto each other as they whipped tears from their eyes. Slowly understanding dawned on the faces of the surrounding students, and more laughs joined theirs. Harry risked a glance over at the head table, Snape looked as though he'd been chewing on a wasp while McGonagall looked torn between amusement and horror, and Dumbledore was merrily laughing away. Draco grinned unabashed at his long-time friend, who sighed a long suffering sigh.

Narcissa took a deep breath raising her hand to knock on the door of the cottage, Molly had offered to go with her but the blonde had declined, this was something she had to do for herself. The door opened just a crack and she found herself being subjected to a suspicious glare from her oldest sister.

"…I'm sorry." That hadn't been where she'd intended to start, but all the planned speeches flew out of her mind when confronted by her sister leaving instead one simple broken sentence.

The door opened just a bit more and Andromeda seemed to be wrestling with something before she sighed, letting her sister inside. "What do you want?" She scowled as the younger stepped through.

"…I…" Narcissa's brow crinkled, "I made a mistake and it's taken me far too long to realise. I should have done this years ago or never turned my back." It came out in a rush, "I didn't know what to do, Bella was so angry and Luci-" she broke off with a furious scowl at the two names, "It's no excuse but I…I'm sorry." She finished lamely.

Andromeda's expression softened and making a decision lead her into the kitchen, the kettle going on with a flick of her wand, "What did he do?" she'd suspected over the years that Lucius was the thing which stood between her youngest sister swallowing her pride and her staying away.

Narcissa's face filled with pain, and her hands shook as she accepted the warm cup, the whole sorry story came out in a rush. From Lucius' dubious sorrow over his previous allegiance, to her suspicions that he had something to do with the prior year, to his current bull headed cruelty and finally his claims that he wouldn't let her return to the manor until she agreed to help him get a new heir.
