In this fic Mustang aims to become the Minister of Magic, but is settling at the moment for the new head boy for the Alchemists. Everyone from FMA are in this new house. It sorts every four years, unlike regular sorting procedures and the sorting hat has been passed down the Alchemist house line for generations. You will find out more about the house as the story progresses, so stay tuned.

"So, what do we need now?" Edward Elric asked his blonde haired companion who's checking their list of items.

"Um, the books… that's Flourish and Blotts." She replied. Falling into step they wander around Diagon Alley until they find the pokey shop with gold flaking writing that reads: Flourish and Blotts.
As they entered the shop, the manager came hurrying towards them in a fluster.

"Hogwarts?" He asked abruptly, "Come to get your new books?" Before the pair could answer he ushers them towards a large wrought-iron cage in which dozens of monstrous looking things tear at each other mercilessly. It took them a while to realise that they were actually books.

"Stand back." The manager commands, trying to sound in control even though he's shaking, he pulls on thick leather gloves, picks up a large knobbly walking stick and proceeds to the door of the monsters' book cage.
He flings open the door and manages to wrestle two copies of the Monsters' Book of Monsters out of the cage, escaping with only mild cuts up his arms. He pulls out a battered looking wand and muttering a spell under his breath he taps both of them in turn; thick leather strips shoot out of his wand with a flourish and bind the hostile books.

The manager gives the two teenagers a book each and asks, "Anything else I can help you with?"

"Erm, yes. We need The Intermediate Transfiguration, The Standard Book of Spells, Grade Three and Unfogging the Future." The blonde says. The manager gives them each their requested books. Which they receive extremely gratefully.

"That'd be, sixteen Galleons for the both of you." He states. The blonde goes to reach into her pockets, but the boy stops her.

"No, Winry. It's fine, I got this." Edward says, pulling out the correct amount of gold from his own pocket and tossing in a few extra Galleons as a tip. The manager's face lights up like the Blackpool Pier as he thanks them, then he waves them on, out of his shop.

Ed grabs her arm to head back to the Leaky Cauldron. Winry stops abruptly, causing Ed to turns and looks at her questioningly.

"Wait, there's something I need to get first. I'll meet you there." Winry explains.

"O-okay." Ed replies looking slightly confused, wondering what on earth she needs. He carries on his way to the Leaky Cauldron. When the pub is finally in sight Edward sighs a breath of relief, thankful that he didn't get lost… again.

BAM.

Ed goes flying, his books spray out of his grasp and he lands heavily on his automail. Feeling his metal arm he's relieved that nothing feels out of place and he won't have an angry mechanic to deal with later. He looks up to see a dark haired kid, who looks about his age, cursing under his breath and picking up both Ed's and his books. The boy gives a hand to Ed which he gratefully accepts, letting the messy haired kid pull him up. The boy hands Ed his books and rubs the back of his neck in embarrassment, Ed smiles gratefully.

"Sorry mate, I didn't see you there." The kid says with a nervous chuckle, in an instant Ed's smile drops from his face and his left eye starts twitching.

"WHO ARE YOU CALLING SO SMALL THAT THEY DON'T HAVE A PROBLEM GETTING SQUISHED BY A BOOK BECAUSE THEY'D FIT IN THE GAPS IN THE PAGES?!" Ed explodes, flapping his arms about with a murderous gleam in his eyes.

"Nobody said that!" the kid exclaimed pushing his fringe out of his eyes.

"WHO THE HELL DO YOU THINK YOU ARE?!"

"Err… Harry, Harry Potter." Harry says a bit confused.

"You had to think about what your name is?!" Ed looks at Harry in disbelief.

"Well that's a new reaction." Harry mutters under his breath, then raises his voice slightly, "You know who I am, now who are you?"

"I'm Edward Elric but call me Ed." Ed says jamming a thumb in the direction of his chest.

"So are you starting at Hogwarts?" Harry asks, trying to strike up a conversation. Ed's eye twitches dangerously.

"I-I mean… what year are you in?" Harry quickly backpedals.

"Going into my third year." Ed states nonchalantly.

"No way! You're in my year?!" Harry exclaims, "What house are you in?"

"Gryffindor, same as you."

Harry's jaw drops to the floor. "You've been in my dorm for two whole years and I didn't even notice."

"WHO'RE YOU CALLING SO SMALL THEY CAN'T BE SEEN WITH OUT A REALLY POWERFUL MICROSC-?!" before he could finish his rant Edward falls to the floor clutching his head.

"Dammit Winry, you jerk!" Harry stares at him confused, his confusion doubling when his eyes wander to the wrench lying next to his feet. Harry follows Ed's glare and sees a teenager with long blonde hair pulled into a rough ponytail, her bangs falling from right to left across her forehead and a curtain of hair framing the sides of her face.

"Edward, leave the poor boy alone! He didn't say that!" She admonishes sternly.

"Hey! I'm in your year!" Harry replies indignantly.

"Yeah, I know!" Winry says stubbornly. Ed lobs Winry's wrench back at her and she catches it solidly in her right hand. Winry helps Edward up.

"Sorry about him." Winry says giving Harry an apologetic smile.

"Harry! HARRY!" the three of them turn to face the voice. Two people were sitting outside Florean Fortescue's Ice-Cream Parlour. A girl with bushy brown hair and a tall gangling boy with flaming red hair and a long nose. Harry started to walk towards his friends; he turned around to look at the pair, he beckons for them to follow him.

"Finally!" says the ginger one, "We went to the Leaky Cauldron but they said you'd left, and we went to Flourish and Blotts, and Madam Malkin's, and-"

"I got all my school stuff last week, and how do you know I'm staying at the Leaky Cauldron?"

"Dad." Ron answered simply.

"Did you really blow up your aunt, Harry?" Hermione says in a serious voice, then she notices the two new people sitting with them, "And who are you?" She asks in an uppity voice.

"Seriously?! Has anyone noticed that we're in the same house as them?" Ed exclaims. Winry sighs.

"As much as I agree with Edward, just ignore him. I'm Winry Rockbell and this is Edward Elric."

"But you can call me Ed." He butts in.

"You're in the same house as us?" Ron asks.

"I'm in the same dorm as you!" Ed replies.

"No offence mate, but I think I would remember you and your friend if you were in our house."

"Well we spent most of our time researching something in the library." Ed covers.

"How come Hermione doesn't know you then?"

"Uh- it was the restricted section." Winry adds.

"How did you get into the restricted section without an invisibility cloak?" Harry blurts out. Hermione nudges him and he immediately slaps a hand over his mouth.

"You have an invisibility cloak?" Ed asks sceptically.

"Erm… no- I mean yes, I mean. Why'd you think that?" Harry tries to cover; Ed and Winry share a look.

"We better be heading back to the Leaky Cauldron." Hermione quickly changes the subject, looking at Ed and Winry she adds, as if by an after-thought, "You two coming?"
They both nod and follow the trio back to the Leaky Cauldron.

As soon as they enter the threshold of the Leaky Cauldron Edward and Winry are surrounded by a group of red-headed people. Breaking away from the family the two manage to find a quieter place.

"Winry, I just need to get something, I'll be right back alright?" Ed asks, she nods and he sprints up the stairs. Winry sighs and looks down at the long package she's been carrying. She sneaks a glance at the family over by the bar, she sees them laughing and smiling, she wonders if that's what it would be like if her parents and Ed's brother and mum were still alive. The sound of uneven footsteps hurtling down the stairs pulls her out of her reverie. She looks to her right and sees Ed panting slightly, doubled over. Time for their annual tradition.

"Here you are Winry, happy new school year." Ed grins, handing Winry a package suspiciously similar to the one she's holding.

"And to you Ed, happy new school year." She smiles, handing him his gift.

Unbeknownst to them the Weasleys and Harry and Hermione were watching this exchange.

"How did we not know they're in our house?" Harry says to Ron and Hermione.

"How do you not know Ed and Winry?!" Fred and George exclaim in unison.

"They're the best Quidditch players in the school." Fred explains.

"Then how come they're not on the Quidditch team?!" Harry says derisively.

"They don't think they're good enough." George says simply.

"You've got to be kidding!" Ed and Winry shout in unison. Surrounded in brown paper packaging laid two magnificent gleaming broomsticks, their eyes roved from the golden registration number at the top of the mahogany handle right down to the perfectly smooth streamlined birch twigs that made up the tail. The golden name at the top of both handles read the same thing: Firebolt.

"We bought each other the same bloody present!" Ed says, they look at each other and burst out laughing. As if drawn in by the shouts, the Weasleys, with Harry and Hermione in tow, float over to the laughing teenagers. They gasp at the sight before them. Ron looks like he's about to faint.

"Is that-?" George starts.

"It is-" Fred says.

"Firebolts." They say in unison.
Recovered from his initial shock, Ron finally manages to string a sentence together.

"What- how? You can both afford to get each other Firebolts! How?!"

"Sorry about our brother-" Fred apologizes.

"-Yeah, we always thought he was part troll-"George adds.

"-Never thought he'd confirm it for us though." They finish together. Everyone laughs at that, even Ron, apart from Hermione and Percy.

"Now, I think we've bothered these two enough already and I'm sure their parents are waiting for them." Mrs. Weasley says kindly.
Winry's eyes widen and tears spring into her eyes. Ed's expression darkens considerably.

"Yeah, in heaven maybe." Ed says venomously before storming up the stairs. Winry quickly apologizes before hurtling up to her own room, remembering to take the Firebolts with her. Leaving everyone stunned.

"Tell me, what are those children's names?" Mrs. Weasley asks abruptly.

"Winry Rockbell and Edward Elric." The twins supply.

"That explains it." She murmurs under her breath.

"Explains what?" Harry asks curiously.

"Why they're so affected by the mention of their parents, they don't have any." Mrs. Weasley states, "You should be off to bed now, you've got an early start in the morning. We should invite Ed and Winry to come along too." And with that she leaves. Soon after Mr. Weasley follows, as does Percy. Leaving only the trio, the twins and Ginny.

"I wonder what mum meant." Ron says racking his brains.

"Yes, I think we need to do some research on them- it could be important." Hermione adds.

"Don't you two want to find out?" Harry asks Fred and George.

"Nah." They say together.

"Why not?!" Ron exclaims.

"You won't like what you find." And on that note, they leave, leaving the trio and Ginny gaping at their retreating figures, wondering what in the hell they meant.
