A/N: So…..it has been over a year since my last update…미안해! (That's my new thing…well, newish. It's been going on for a two years at least. ANYWAY, I love Korea now. Kudos for who knows the meaning of the phrase!) I've been really busy with college and work, and on top of it all, I'm applying to study abroad in Korea for next year! I really hope I get accepted into the program…Anyway, enjoy this next chapter! :)

Previously, on Revised Bloodred Magic…

McGonagall caught hold of his hand before he could go farther. "Wait, boy. Don't you have something to say to me? Something to apologize for?"

Ed glared right into her eyes. What was her deal? "No, I'm not sorry about anything, you damn hag." He growled, storming out of her sight. "I'll find the damn room on my own!"

Chapter 4:

Edward glanced nervously around him. He had hastily claimed to be able to find his own way and stormed off…which was, perhaps, not a very good idea. Now that he had some time to cool off, he realized that he was totally, utterly, and completely lost. After he had passed the strange moving staircase, he happened across a door. With a sigh, he opened the door, wary of what might be behind it.

Everything seemed safe enough, so he wandered a few steps inside of the large room. Taking a look around, he noticed that there were various things lying around in no particular order, gathering dust. It seemed as if no one had been there in at least a year. Ed moved forward, continuing to look around. Finally, his eyes fell upon a tall object near the back that was covered with a thick cloth. He cautiously approached it, a strange feeling spreading throughout him.

As he reached the object, he gently pulled off the cloth and stepped back, blinking in surprise. What he initially saw was an antique mirror that probably was used for giants. Then, as he looked again, he noticed that what he saw was not his own reflection. Edward's mouth went dry as he numbly stepped back and sat down, his eyes never leaving the reflection.

He saw himself standing, a broad smile on his face. He was taller, but the most notable thing was that he no longer had the automail arm and leg…instead, healthy looking flesh and bone took their place. Beside him, in the reflection, he saw his family: his mother, smiling next to his father. Alphonse had an arm around Ed's shoulders.

Biting his lip, he looked down, away from the cruel image. He gripped at his automail arm, reality taking priority. Ed slowly got to his feet and started to walk back towards the door to his exit. However, as he neared the door, he couldn't help but shake the strange feeling that he had seen the mirror before. He chanced another look behind him at the mirror, which was well over 50 feet away at this time. The image had changed. This time, something strange was in the mirror. Like an angel? He couldn't tell what it was. Before he could move closer to the mirror to get a better look, the image vanished.

The blond male blinked a couple times and shook his head before quickly departing the room.

"Damn wizards…" He muttered darkly under his breath. "They make such strange, idiotic things."

After wandering about the castle for what seemed like minutes, Edward eventually found his way back at the Great Hall. Even from behind the door, he could hear Roy's urgent voice, arguing with an older voice—of which he could safely assume belonged to Albus Dumbledore. His anger towards Roy from having his superior foolishly take advantage of him had not completely subsided. In fact, it had risen again after simply hearing Mustang's voice.

As stealthy as a cat, he slinked up directly behind Roy Mustang and quickly made semi-harsh, nonfatal jab with his finger into Roy's side. While Roy doubled over with a yelp of pain, Edward snickered evilly.

"That's what you deserve, bastard."

Roy turned quickly, and the pain disappeared from his face. Instead, relief and worry overtook his expression.

"Fullmetal!" His voice sounded stern, but still the worry was there. "Do you have any idea how long you were gone?"

That elicited a short shake of the head on Edward's part. He honestly thought he was gone, at most, 30 minutes. Dumbledore watched on, a thoughtful expression on his face as he watched the exchange.

"You….you idiot." Roy's voice was mostly a mutter at that phrase—such to the point that Ed barely heard it. "You were gone for a little over an hour. I'm told that newcomers have been seriously injured in this castle before…"

Edward simply blinked and shook his head. He didn't feel any danger when wandering the castle. "Well, I'm not hurt, am I? Besides, you and I both know that I've been through a hell of a lot worse in the past…" He glanced down at his automail arm, which was covered by his coat.

Roy stood back a little. It was true. Edward had been through worse. In fact, the blonde had technically died before. That thought made Roy cringe, a dark feeling in him.

While Roy was having his little dark party a few feet away, Ed snuck an innocent look up, though guilt still showed through. His voice was slightly pouty, which was uncharacteristic of him. "Besides…" the blond muttered, "it's not like I left for the joy of it. It's your fault I left."

Immediately Roy looked exasperated. "Damn it Fullmetal! A little thing like that got you all riled up? You're practically an adult, Edward. It's time for you to grow up."

A hurt expression appeared on Ed's face, causing Roy to inwardly groan. Great. Roy had wanted to make up with Edward…not make things worse!

"I'm…sorry Ed. I didn't mean it like that. Why don't we go to our quarters. I think a good night's sleep will do wonders." The dark haired man glanced over at Dumbledore. "I believe I remember the way. I'm sure we'll see you tomorrow."

Edward stayed silent, a glowering look on his face. His emotions were a mixture of fury, hurt, and submission. He simply followed Roy towards the room they were to share until he was publicly sorted in a week and a half…when their official duties would begin. They arrived at the painting guarding Roy's door. Ed didn't bother to even look at the painting as he (not so) patiently waited for the door to swing open. He stormed past Roy and quickly joined Kio, his mini-9 tailed fox on the master bed. Oddly, Obsidian was lying on the smaller bed, so Ed left that bed to his superior. It would only serve him right.

He shut his eyes and pretended to sleep, all the while listening to Roy watch him before the dark haired man sighed and accepted the fact that Edward wasn't going to talk to him. There was enough time for them to make up before they had to officially begin their duties.

Eventually Edward's pretense faded into a reality as he drifted off to sleep, the small fox snuggling up next to him in the large bed.

The following week went by surprisingly slowly. Edward had woken up early each morning and went to bed late each night in order to study the books within the library. He was a fast learner, which he would be glad to be when he began classes side by side with his charge. Even though he was a beginner, he quickly grasped the concepts and was able to memorize most of the books he needed to know.

Throughout the week, however, Roy found himself unable to reconcile with the younger male. Eventually he gave up and stuck to simply studying alongside Edward. He himself was slower at grasping the concepts, and he had a weaker ability to memorize, but Roy also found that magic was easier than alchemy.

From time to time, Roy would get this sensation that someone was watching them, and he would glance at the corner to see a cat waving its tail in a corner. Its eyes would catch and hold his, making Roy feel like there was something human about the creature…though he always broke his gaze away to continue his studies.

When it seemed like he and Edward would not be making up, something unusual happened on the night before their work would officially begin. Edward approached him and apologized. Roy blinked and nodded slowly, accepting the apology…though there was not much fault at Edward's part.

Ed smiled brightly, of which could capture the attention of even the darkest heart. This smile made Roy think, though. How could Edward thrash around the bed at night with nightmares when he seemed so happy on the outside when he was awake. There was something strange about that, and he vowed to himself that he would find out how to help Edward. After all, it was Roy's duty…

He shook those words from his head. It wasn't safe to think such things in a place where his thoughts could possibly be overheard. He got up to his feet from his seat on the sofa and started to leave the room.

Ed looked up absently, book in his hands. "Are you going somewhere?"

Roy turned and smiled tightly, a growing hunger in him. "Just to grab a late-night snack. Would you like me to bring you anything?" Roy felt bad about lying to Edward, but there was no way he could divulge the entire truth to the young alchemist. Not yet.

Ed smiled and nodded. "You know…those noodles with red sauce…?" As soon as Ed saw the guarded/annoyed look on Roy's face, he pulled on puppy eyes. "Please? I feel homesick…"

Ed grinned triumphantly as Roy left, sighing out in defeat. Could any sane person resist such adorable eyes?

The next morning, Edward and Roy got on the Hogwarts Express, which was to leave towards Platform 9 ¾ in order to collect all the students. Ed didn't seem too happy that they were in for a long, two way trip, but they had no choice. Ed chose one of the compartments in the back and promptly laid down on one side, completely taking control over those seats.

"Wake me when we get there." He grumbled, snuggling into the hard seats in order to find a more comfortable position. Roy snorted and simply sat down, pulling out some history book on Hogwarts.

"Don't blame me if some kid sits on your face," Roy murmured easily in reply as he began to pick up from where he left off. "I won't rescue you."

Ed paid this no mind as he sunk into a sleep.

A couple hours passed until the train finally reached the station in London. Roy looked up from his book and nudged Edward with his foot.

"Hey. Fullmetal. Wake up."

Ed slowly opened his eyes and groaned ungracefully as he got up to his feet. After popping his back and various other parts of his body, he lumbered over to the seat next to Roy and plopped down, leaning his head against the wall.

"Remind me again why we decided to take up this mission?" He growled, nudging the man in the ribs.

Roy winced, a bruise fading from the last time Ed poked him. "Because we like being friends with the magic community; and because they promised to give us the magical recipe to make a sorcerer's stone."

After hearing this, Ed became subdued and entered his own private thoughts.

Time passed by, again very slowly. It seemed as if hours passed as the train filled up with its passengers. As the train finally pulled away from the station, a small group of kids opened the compartment door.

"Uh, hullo." Came the distinctively British accent. "Do you mind…?"

Edward and Roy looked to the door in unison. Ed scowled and motioned a hand, not saying a word. He was still grumpy from the long ride…he had always disliked long train rides. Roy, on the other hand, smiled welcomingly as was expected of a teacher.

"Of course! Come in and take a seat." He retained the warm smile as the three students sat down in front of them.

Edward looked back towards them, taking their image in. The one on the far left, closest to the door, was a little taller than Edward, and he had brunette hair, odd looking glasses, and a lightning scar on his forehead. Next to him sat a red headed male with freckles covering his face. Finally there was a female with bushy brown hair and calculating eyes. She met Ed's gaze evenly, also sizing him up.

'Harry Potter, Ronald Weasly, and Hermione Granger…' Ed thought to himself. He held Hermione's gaze, unwilling to break it first. The kids in front of him were approximately 15 years of age…which was two years younger than he himself was. Eventually Hermione frowned and broke the gaze to look Roy Mustang up and down. She smiled to herself, a bright look in her eyes as she appreciated the man's appearance.

Ron looked from Hermione to Professor Mustang and frowned as well. He didn't like the attraction that Hermione was showing. Last time she reacted that way towards a professor, that professor nearly got them all killed.

Ed snorted and leaned back against the window, looking out at the landscape. He had to admit that the view was pretty.

Roy kept up the polite chat with the students while Ed slowly started to really wake up.

"So, Professor Mustang," Harry started, only slightly curiously. "Are you the new Defense Against the Dark Arts teacher?" As he thought about it, he knew that had to be the case. There were no other spots open.

Roy simply smiled and shook his head. "I'm afraid not, Mr. Potter. I'm teaching a new subject for fifth years this year…" He hesitated before adding. "And this year only. I'm temporary. I highly suggest you take the class."

Hermione looked highly interested as she leaned forward, a hand resting all the way on Roy's knee. Ed glanced and snorted before looking away again. If sex-crazed Roy wanted to break some rules by sexing it up with a student, who was he to stop him? It did bother Ed though…

"What kind of subject is it?" Her eyes were bright and genuinely interested—not just her hormones. "And what type of subject would be offered only one year? I mean…" She trailed off, smile fading slightly when Roy gently slid her hand off his knee.

"Well, I'm not allowed to reveal the details yet, but I am positive you three would love it. I'm a bit of…an expert in the field." He laughed softly. "I'm actually the leading expert, really."

Ed cast a ridiculing look at Roy, another snort escaping him. "Expert?" He muttered in slight amusement.

Roy ignored this and continued polite conversation the rest of the trip while Ed went back to ignoring the three.

A/N: So, I was going to put the bit about Malfoy coming in, but that's a little too cliché now. I'll have some more realistic confrontation later. Besides, I don't want the alchemy being exhibited before its time. ;) So, let me know what you think about this chapter. It's been a long time since I wrote for ffnet, and I didn't even beta this one. I hope that you like it!
