world. And boy had it been a long three months. Though Edward had had to learn more than him. He did have four years of school to catch up on after all. While all Mustang had been forced to dYa I know there are over a hundred of these. Trust me I looked. But I thought hey why not. I can't guarantee that all the chapters are going to be this long but I'll try and please don't get mad if I don't update often. My updating depends on the mood I in and what I'm into at the moment. Though I will update as soon as possible.

On the Train

A thick veil of smoke covered Platform 9 ¾ as the Hogwarts Express waited to carry the students to another year of school. Sirius's tail wagged back and forth as he ran around the platform tongue hanging out of his open mouth. "SNUFFLES!" Sirius turned and ran toward the voice that had called to him only to run right into a boy that hadn't been there seconds before. Bright yellow eyes met piercing gold as the boy he had knocked over looked at him a smiled a small smile. The boy looked like he could be a first year but the world weary look in his golden eyes told Sirius otherwise. This boy had been through a lot in his short life. The boy's smile got a bit bigger before he patted Sirius on the head with a gloved hand and stood brushing himself off. The boy then turned and ran toward the front of the train. Sirius watched as he ran up to a dark eyed man wearing something that looked like a muggle military uniform. Lilly had taken him and James to see a war movie once. It had to be part of a muggle uniform because Auror uniforms didn't look like that. Sirius shook his head trying to get his thoughts back on what was important at that moment before he began running toward the large group of people he had come with. It was time to say good- bye to Harry. He was unaware of the sharp golden eyes following his movements.

Edward Elric sighed as he watched the large black dog run toward the other side of the platform. Something about that dog didn't seem right to him. Or maybe dogs just got that big here he didn't know. "I've never seen a dog like that before." Roy Mustang Edward's commanding officer said as he shifted Stallion's leash to his other hand. Stallion was an overly large Great Dane pup with oddly colored fur. Red, black, and mahogany brown streaks ran through her fur in swirling patters that were impossible to trace. Only the tips of her feet, tail, and her stomach were white. An earthy brown leather collar hung around her neck. Carved deeply into the leather were a series of runes that ran all the way around. Carved on the front of her license was a basic transmutation circle while her name and owner adorned the back. Edward scratched the back of his neck as he looked at Mustang and then at his pocket watch, it was almost time. "We need to board Colonel or Stallion may have to stay with all the other animals in the back." Mustang sighed as he followed Edward onto the train. Mustang grunted as he pulled his trunk through the hall of the train and towards the first empty compartment they could find.

Edward on the other hand didn't have to worry about an over large trunk because most of his things were already at the school. He had been smart and went with one of the teachers ay the beginning of the year to get his things while Mustang had waited till the weekend before school started. There for Edward wasn't having any problems with the two items he was taking back to the school with him. Edward's ever present traveling case was clutched in his right hand and a blanket filled basket tucked under his left arm. The basket's occupant being asleep at the moment. A small kitten slept within the folds of a light blue blanket. The kitten was the reason he had went back to Diagon Alley with Mustang. The kitten having been named Gear due to the oddity that was its fur was just as lively and playful as Stallion, who had no problems with the small animal. The kittens fur was a pale silver- grey with gold, a darker silver, and bronze spots covering its fur. The thing about the fur that was so amusing was that the spots of color on his fur were actually shaped like gears. A copper colored collar rested loosely around his neck. It had the same design on it that Stallion's had. Runes carved into the collar and a basic transmutation circle carved onto the font of the license. "You know Ed you could help me." Mustang said as he tried to lift his trunk up to the overhead racks. Edward hmmed and looked at his commanding officer a small battle going on inside his head. To help or not to help that is the question. Mustang himself looked as if he was going to set flame to the trunk at any second. Edward laughed to himself for a second before placing his case on the overhead rack and Gear's blanket on the seat before helping Mustang with his trunk.

Stallion laid happily underneath the seat across for Edward and Gear. Mustang plopped down on the seat across from Edward and watched as the young alchemist stretched out on his seat. The sad thing was that his feet didn't even touch the other wall. Edward yawned. "I can't believe we took this mission." Gears basket laid on Edward's lap. Normally Mustang would have told Edward to shut up and get over it with it but he had to agree with him a bit on this one. This time though he couldn't help but agree with him. They had spent the last three months at Hogwarts being educated in the ways of the wizarding o was make a lesson plan and such for classes and learn a lot of little things to prevent procrastinating. Not that many of them helped. It would be strange though. That night in front of a school full of students he would be introduced as Roy Mustang Alchemy professor and Edward would be playing the part of a student and his assistant. That and they'd bother be playing one role that neither of them had been happy with at first. Father and son.

Yes they were to play father and son even though they looked nothing alike and Edward's last name wasn't Mustang but Elric. Not that they weren't prepared for any questions that would be flung their way. They had answers for any question they could think of. They had answers for why their last names were different and why Edward wore gloves all the time. The thing that was hardest for them though was actually acting like they were father and son.

It had been very hard for Edward to call Mustang dad or father and the habit had only really just formed a few weeks ago. He almost never called Mustang colonel anymore. Even when they were alone he still called him dad and it had come as a surprise for both of them when Edward had called him dad and Mustang had answered as if it was the most natural thing in the world. The odd thing was though that not only did Mustang not mind being called dad but he felt like Edward's father the more Edward called him that. In a way he liked it. Edward needed a father figure in his life. Or a good one at least since the though of his real father often caused the teen to growl and curse. So in Mustang's mind he had to be the next best thing really. They liked each other not that anyone could tell. They liked each other but they liked annoying each other more that was all. Mustang smiled as he looked at Edward's reflection in the window. As usual he was asleep and the train had only been moving for about fifteen minutes. Edward looked very peaceful when he was asleep . All the outward signs of stress seemed to disappear and his body seemed to relax as much as it could with two fake limbs. It was funny and yet sad at the same time. He had learned more about Edward Elric as a person in the last three months than he had in the last four years. It was strange seeing Edward so much now. When before he saw him and his brother two or three days every few months. Now he saw him every day. Mustang had learned a lot about him and even then that wasn't easy. He knew the boys sleeping habits, when he'd eat if he was busy doing something and even how long Edward tended to be in the shower. He knew that Edward had a photographic memory and that he spent at least an hour a day doing physical training. He had also learned that when the weather was really bad or cold that Edward's normal routine vanished into thin air. Depending on the weather and temperature made all the difference with what he did that day. So on the first very cold rainy day that summer he had learned one of the most important lessons about Edward he would ever learn. Edward cold, rain, and or snow did not mix at all. Mustang hated to admit it but when that cold rainy day had come Edward's action or lack thereof had scared the crap out of him.

He had thought at first the Edward had had some sort of attack or something that night when he had refused to get out of bed that morning. Now Mustang could appreciate a good nights sleep and even sleeping most of the day away but noon was pushing it. Of course when he had gone to wake Edward up the boy had refused point blank to get out of bed or even look at him. Hell the boy had refused to move and Mustang had been answered in mumbles. He found out ten minutes later what was wrong. Edward's reply of "It's raining and cold and I hurt. I want to sleep till it gets warm again." had told him everything. The solution had been quite simple of course. Mustang had left Edward alone for about ten more minutes and the come back and literally carried the boy into the bathroom and dumped him into the bathtub. The hot bath and a rub down of some jelly stuff that made Mustang's hand's go numb had done wonder for Edward. The two together had at least made it easier for him to move around. Though Mustang had started to worry about what would happen come winter if cold rainy day's made Edward's muscles act up like that. Winter was going to be hell. He had of course mentioned the affect of the cold weather to Dumbledore and the old headmaster had yet to reply. The sound of nearing voices shook Mustang out of his thought. The voices sounded young which meant that they were teenagers. Students that hadn't been able to find a compartment in the back and had been forced toward the front of the train.

Not a minute later three shadowy figures stood in front of his compartment door. Mustang sighed and stood moving over to Edward's seat so the teems could sit together. Gently Mustang lifted up Edward's feet and sat down placing Edward's feet on his left leg while fighting the mad urge to laugh at how short Edward really was. Seconds later the compartment door opened and three teens entered. Roy nodded at their unasked question and the teens proceeded to put their things on the overhead rack. The three teens stared at Mustang and Edward for a minute before they began talking amongst themselves. Had they been looking at his cloths. In all truths they were a little strange but not all that strange. He had seen stranger cloths on the witch's and wizards in Diagon Alley. He was wearing military issue pants and boots but his shirt was a regular white button up with the sleeves rolled up to his elbows. He wasn't even wearing his gloves though they we're in his back pocket. Maybe they hadn't been staring at him but at Edward. It was more likely seeing how he was wearing his usual black boots and a pair of black jeans. A black button up shirt with the sleeves rolled down to cover his automail arm and a pair of white gloves about three inches linger that his usual ones. Once again to help hide his automail. Yes they must have been starring at Edward. Roy let out a sigh and looked back at the teenager, who had stopped talking sometime during his analysis of his and Edward's clothing. They were once again staring at him and Edward.

"Yes?" The bushy haired girl in the group squeaked and looked embarrassed before looking Mustang in the eyes. " I was just wondering sir but who exactly are you?" Roy smiled a bit and then smiled at the girl and her friends. He wasn't supposed to have to do this until later that night. "I Ms. Granger am Roy Mustang and I'm here to teach." Mustang said before pointing down at the still Sleeping Edward. "This is my son Edward." Hermione looked a bit shocked. She had thought that he was a student. A seventh year she had never noticed or something and that the boy sleeping next to him was a childhood friend or his little brother maybe. She hadn't thought that he was a teacher and his son. Hermione looked at Ron and Harry only to see the same shocked looks on their faces. Ron cleared his throat before fixing Mustang with a suspicious glare. "How did you know her name?" Mustang looked at him with a raised eyebrow. "Hogwarts has files on every student. The file includes Name Birthday Blood Type so on and so forth and it also has a picture of the student. I know almost every student by face and name from year three to year seven. Come now how do you think all the other teachers know your names when you get to school? They shore don't memorize them after you come." Mustang paused for a moment before continuing. "I know all your names." The three teens looked at each other mouths wide open for any passing flies. The next two hours on the train ride were almost too quiet in Mustangs opinion. He was used to some sort of noise and movement lots of movement. Harry and his friends had seemed to decide that Mustang wasn't a social person seeing how they hadn't said anything to him sice Ron and Hermione had asked their questions.

That of course wasn't true Mustang could be very social when he wanted to be with was almost all the time. Hermione looked up from her book and eyed both Mustang and Edward. She had been quite amazed to find out that he was a new teacher and that the boy sleeping was his son when they looked nothing alike. Hermione quickly looked back down at her book as Mustang stood up and stretched several bones in his back popping while he did so. Mustang glanced bad at Edward to be shore he hadn't woken the bot when he had stood up. He of course hadn't. Edward was used to sleeping on trains. Mustang turned and looked at Harry and his friends before pointing at Edward. "If he wakes up while I'm gone will you let him know that Stallion and I have gone to stretch out legs." As if summoned by his words Stallion emerged from underneath Harry, Hermione, and Ron's seat yawning. It seemed she had been sleeping as well. As Harry nodded Mustang left the compartment followed closely by Stallion. Now hat they had been left alone with the still sleeping Edward all three of them began talking at once. "Do you think he's a Death Eater? Ron asked as he eyed Edward from his seat." Jeez Ron at least give them a chance. Not everyone's a Death Eater is disguise." Harry said as he looked at his friend and the at the sleeping form of Edward. Something about him seemed storage but he couldn't decide what. The man Mustang had been nice enough but Edward just had this look about him. Something about him just seemed to scream 'I can take care of myself but a little help every once in a while would be nice'. Edward just looked like trouble would find him no matter where he went. It was possible that it was because his hair was so long it seemed to scream 'punk'. That or perhaps it was because of the light scars he could see covering the boys face. The most visible being about two inches long and resting above his right eye.

"So do you think his dad is the new Defense Against the Dark Arts teacher?" Hermione asked. "It's possible though his dad must be nuts to think he could handle the job." They really needed a good defense teacher now. The sound of the snack trolley filled their ears as the witch drew nearer to their compartment. All three of them looked at Edward. "So do you think we should wake him up?" Hermione asked as she looked at her friends. If they were going to wake him she didn't want to be the one to do it. Harry nodded and then bent down and shook Edward's shoulder very lightly. Without opening his eyes Edward let out a very sleepy sounding. "What?" Harry herd Ron snort from behind him and he shot his friend a glare over his shoulder only to turn around and come face to face with a pair of deep golden eyes. Bright green and deep gold stared at each other for a moment before breaking contact as Edward stretched and yawned several bones popping as he sis. "You woke me for a reason?" Edward asked as he eyed Harry and the others. Hermione stared at Edward for a moment before realizing that he had asked a question. "Oh we wanted to be shore that you had a chance to get something to eat if you wanted to." "Well thanks. I miss breakfast this morning and it would have sucked to have had to wait till dinner to eat."

Edward offered them a small smile of thank before the door to their compartment opened and the Trolley Witch appeared. "Anything off the trolley dears?" Moments later Edward sat on his seat munching on a Chocolate frog while watching Gear play with a bell ball, a plastic ball with a bell on the inside. Edward had freed him from the blue blanket of his basket soon after he had gotten his food. He had petted the kitten for a moment before letting him down to play. The compartment was mostly silent the only real sound being that of the bell. "So is that Mustang guy really your father? I mean to say that you two don't look anything alike is all." Edward glanced at Ron before speaking. "Yes. He's my father. I get my looks from my mother. We don't even have the same last name. Though that's only because he and my mother were never married and after she died I decided to keep her name so that the family wouldn't die out. She was the last Elric. At least that we know of." Ron had the decency to look sheepish and a little guilty. He hadn't meant to cause Edward to recall anything he didn't want to. And by the sad look on his face his mothers death was one of those thing. The next half hour or so passed in silence. Each of the teens doing something different to pass the time. Edward watched through half opened eyes as

Harry and his friends amused themselves. He knew all their names of course having read all the school files instead of most of them like Mustang. He was here to keep an eye on Harry after all. Mustang was here to keep any eye on the students in general. After all who better to watch over the warriors of the next great war than a couple of seasoned soldiers. Edward was halfway back asleep when the door to their compartment banged open. Instead of Mustang and Stallion like Edward Had expected a boy with short blond hair and a rude look stepped in. "So this is where you were hiding Potter. I thought that you hadn't come this year but here you are. Such a shame and I was so hoping." Malfoy sneered as he looked at Harry and his friends. Edward huffed. So much for getting back to sleep anytime soon.
