Chapter Text
Edward Elric had a system.
He arrived to Central University's chemistry building twelve minutes before every lecture, early enough to claim his unofficial spot. Second row, third seat from the left, which put him at the precise angle where he could read Professor Marcoh’s lips clearly without straining his neck. When possible, he always sat with his back to the wall.
He always assessed a room before settling in: how loud it was, how much echo, whether the background noise would overwhelm his processors' ability to filter speech.
When a room was too loud or too reverberant, the processor struggled to separate voices from everything else, and what came through smeared into noise he couldn't use. While he was use to it, it didn’t make it any less annoying.
He had a system, and the system worked, and he had not needed anyone's help in a very long time.
This was important to him. Maybe the most important thing to him. Independence, not needing anyone’s help.
The processors came off every night before bed, which was just maintenance. Charging them every night and just giving his brain a rest from the constant work of processing sound. But sometimes they came off during the day too, when things got to be too much, when the noise was wrong and overwhelming him or the day had worn him down and he just needed the world to go quiet for a while. He'd been doing it since he was a kid. When he took them off at home he put them on the refrigerator. Always on the fridge, in the same spot each time, so that Al and Winry knew without having to ask. It was a system within the system. It meant ‘I need quiet right now’. It meant ‘don't worry, I'm okay, I just need this’. They never had to say any of that out loud. They'd just learned it, the way they'd learned everything about him, from watching.
"You're going to spill that," Alphonse said, signing it at the same time, hands moving alongside his words the way they always did when it was just the two of them. He nodded at the travel mug that Ed was balancing on his knee while simultaneously flipping through his organic chemistry notes.
"I'm not going to spill it." Ed said, and he signed it too.
"You said that last Tuesday." Al said with a smug grin, remembering how well it had gone for Ed last time.
"Last Tuesday was different." Ed replied, clearly annoyed with Al.
"Brother, it was the exact same situation." Al said, signing it too, “And you remember how well that went.”
Ed rolled his eyes, "Drop it, Al."
Al's mouth did a thing, the pressed-flat thing that meant he was choosing not to say the rest of it, but knew he was right. Ed had known that face his entire life and it had never gotten any less irritating.
They sat together outside the science building in the thin September sunlight, the kind Central City produced with grudging reluctance. Like it hadn't quite made up its mind about autumn yet, hadn’t fully committed to the changing seasons and gave little hints of summer still here and there. Around them, students moved in the complicated choreography of the first week of fall semester. Backpacks, coffee cups, and the silent mouths of conversations Ed couldn't quite track at this distance.
Ed was used to it, the visual noise of a crowd. He had learned when he was young to just let it become background noise. He did his best to ignore it, to just let it be.
What he hadn't gotten used to yet, what was still catching him off guard two weeks in to his second year here, was the sheer scale of Central University's campus. Resembool had been small. Not the charming, picturesque kind of small that people in cities romanticized. It was just small. Everyone knew everyone, which meant everyone knew about Ed, and it also meant the particular kind of cruelty that came from familiarity had many years to sharpen itself into something precise.
Here, he was nobody. He was just a sophomore in the chemistry department who happened to communicate primarily in ASL. Someone who wore two small processors hooked over his ears that connected to a magnet on his skull, who sometimes spoke aloud in a voice that he knew, he had heard it on recordings, came out flat and slightly wrong in ways he couldn't fully control. He'd lost most of his hearing by the time he was seven, all of it by age eight, and the years of speech therapy since had gotten him to functional area and stopped somewhere just short of being natural.
Central University had a larger Deaf community than anywhere Ed had ever lived. It wasn’t huge, and they did not have a dedicated program. But the community was large enough that ASL was woven into the campus in small ways that mattered. They had professors who actually signed, an interpreter pool that didn't require three weeks of advance notice, a student body large enough that nobody turned around to stare when Ed signed to Al across the dining hall. Ed had picked this school partly for the chemistry department and partly for it’s ASL community. He hadn't told anyone the second reason because it wasn't something he wanted to explain. He just wanted to be a regular student. He had spent fourteen years in Resembool being a very specific kind of target and he was done with it.
The voice was the thing people reacted to. Not always, not everyone, but enough that Ed had learned to treat it as something to be carefully distributed. Kids in Resembool had been the worst about it. Winry had punched a boy in kindergarten for making sounds back at Ed. She was five years old and had done it without hesitation, and then spent the next twenty minutes crying in the principal's office. Which was when Ed had understood that she was angrier about it than he was. It hadn't stopped there. By the time they were in third grade, Winry had fought enough kids that there was a specific look teachers gave her when they saw Ed being hassled, the bracing expression of someone who knew what was coming. Al had been smaller then, too young to do much to help. But by middle school he'd caught up and developed a different approach, he would walk over to whoever was giving Ed trouble and say something very quietly, something Ed could never lip-read, and it usually worked. Not always. Kids were kids, and some of them decided the attention was worth it. But most of them decided it wasn't.
Ed had built, over years, a system. With people he knew well, Al and Winry or anyone who had earned it, his voice was just his voice. Imperfect and functional, not something he managed. With strangers out in public, things like ordering food or buying things, he pointed or wrote or gestured. Whatever got the message across without the exposure. At school, when he was in class with professors who signed he would also sign. Many of the professors at Central University either signed or knew enough of it to follow. It was clean, it was functional. It meant he could ask a question or answer one without spending anything he didn't have to spend.
Nobody here knew him well enough yet to make it weird. His notebook stayed in his bag and his voice stayed mostly in, and his hands were ready when they needed to be, and that was, for now, exactly what he wanted.
"Winry texted," Al said, signing it simultaneously. "Late again. Lab ran over."
"Obviously." Ed said with a sigh.
"She also says, and I'm quoting directly, 'tell Ed that instant noodles don't count as a food group.'” Al said, chuckling slightly as he read the text aloud.
Ed looked down at his travel mug, which contained some instant coffee he'd made in the apartment's microwave.
"Tell her I had a balanced meal." His hands moved with the words without him thinking about it.
Al gave him the look, the one that said he knew exactly what 'balanced meal' meant with Edward and he was mentally deciding whether it was worth the argument. Ultimately deciding against it, he stood up and shouldered his bag. Al was taller than Ed by almost a head, he had shot up at fifteen and never really stopped, which Ed had opinions about. Al moved with the unhurried ease of someone who never had to calculate the angle of every room he walked into, never had to think about where he stood in a room or how echos in a lecture hall would impact his notes.
"I’ve got anatomy in twenty minutes. You good to get to lab on your own?" Al asked, and he meant it with genuine care, even though Ed found it irritating.
"Yes." Ed said with a sigh, signing it in a hurried way.
Al frowned a little, "The east corridor lighting-"
"I know about the east corridor.” Ed stressed, giving Al a pointed look, “I'll go around."
"I wasn't going to-" Al countered, quick.
"Al."
Al held up both hands, the universal sign for he’d drop it. But he paused for a moment before he left, briefly dropped a hand on Ed's shoulder, just for a second. The way he'd been doing since they were small, and then he was gone, absorbed into the foot traffic crossing the quad.
Ed watched him go. He thought about Al at seven years old, sitting in a doctor's office watching them fit Ed's first processor, not fidgeting and not looking away, just watching with that focused careful attention Al had, like he was memorizing it. Their mother had been in the chair beside Ed, holding his hand. On the way home from the appointment, Al had pressed his face against the car window and said very seriously to his own reflection, ‘I want to do that someday. I want to help kids like Ed’ He had said it the way Al said things that he had already decided, not wondering aloud about them, just announcing a fact about his own future. He had been seven years old and he had not wavered from it since.
Back then, Ed had told him that was stupid. But then he had gone quiet for the rest of the drive. Then, their mom had reached back and squeezed his knee and he'd heard it, her voice. It was slightly different through the processors than he remembered from before, but it was hers. Unmistakably hers, and he didn’t know yet just how few years he had left of that.
Ed packed up his notes and headed for the chemistry building.
Twelve minutes early.
Right on schedule.
Ed was rounding the corner of the Hartmann building's north wing, the long way around because the east corridor lighting was bad and he'd learned that the hard way. When all of a sudden, he collided hard with someone going the other direction.
Ed’s coffee went one way, his notes went another. He would have gone a third if a hand hadn't caught his arm.
"—careful—"
The word was half-muffled by ambient noise, and Ed only caught the tail end of the lip movement. He steadied himself, quickly pulled his arm free, and looked up.
The person who'd caught him was tall. Annoyingly tall, as if height were something people chose specifically to inconvenience him. With black hair and dark eyes currently surveying the scattered pages of Ed's notes with mild concern. He wore a jacket slightly too nice for a university hallway and had the kind of face that registered as handsome with the same immediate certainty as a mathematical proof, which Ed resented on principle.
The man looked at Ed, then at the notes, then back at Ed, and his mouth moved.
Ed caught some of what he was saying, "—sorry, I wasn't.. are you—" and then something he missed.
"Fine," Ed said, two syllables, clipped.
His voice in his own ears was what it always was, flat and slightly effortful, produced with more deliberateness than it looked. Ed hated the way it came out around strangers. But it was faster than anything else, and right now he wanted to be gone.
"Watch where you're going." Ed said, voice flat and with a little more malice than he intended.
The man blinked. Something shifted in his expression, not pity, not the discomfort some people got, just a quiet recognition. He crouched down and started gathering Ed's notes without making anything of it. Ed crouched too, not to be polite, but because his notes were numbered and he didn't trust a stranger to sort them correctly. The man handed over each page in order, which meant he'd noticed they were numbered. Ed filed that observation away without comment.
"Really sorry," the man said. He'd slowed down slightly, not the exaggerated mouthing that people sometimes defaulted to, just a natural adjustment. Careful without being condescending. Ed took the last of his notes and stood.
He left before anything else could happen.
He didn't look back, he had a system to follow.
Roy Mustang stood in the hallway for a moment after the student left.
He was going to be late for his seminar.
But, he was also still holding the last page of someone else's notes. He was about about to hand the page over when the student had already turned and walked away.
He looked at the page. Organic synthesis mechanism, written in neat pencil with handwriting that had been trained into precision. He set it on top of his own notes and started walking.
Roy had seen the processors the moment he'd looked up from the collision, recognized them immediately from the audiology appointments with Maes. He'd adjusted his speech without deciding to, slowed down slightly and made sure his face was readable. It had felt like the right thing to do, not a calculation. What was harder to set aside was the other part, the way the gorgeous blond he had ran into acted. How the blond had sorted through his notes efficiently while barely looking at Roy, the flat careful voice, and the way he'd angled to read Roy's face and then quickly left before Roy say anything else.
Roy made it to his seminar with forty-five seconds to spare. The room was already nearly full. Riza was in the second row, as always, and had saved the seat beside her for him, as always. She then looked up at him with the particular expression she reserved for when he was cutting it close.
"You were almost late," Riza said, not quite quietly enough. Next to her Havoc was grinning, glad Riza was scolding someone besides him.
“Just fashionably late.” Roy replied as he sat down, settled his bag befitting opening his notebook.
"What happened?" Riza asked, “You usually aren’t running late.”
"Nothing, just ran into someone." Roy said, and he thought again about the gorgeous blond with golden eyes and numbered notes.
She looked at him for a moment. Roy avoided her gaze, instead he looked at the board, where the professor was already writing. Riza then went back to her notes.
The seminar started. Roy got his pen out and wrote the date at the top of the page and then spent approximately fifty percent of the next two hours not thinking about the person who'd walked away from him before he could ask their name.
At some point he shifted his notebook and the stray page of organic synthesis, neat pencil and very clearly not his, slid halfway out from between his own notes. Roy tucked it back in without comment.
Besides him. Riza said nothing. But he was aware, in the peripheral way he was aware of most things, that she'd seen it. She had that quality, noticing without announcing. He'd known her since seventh grade and she had never once stopped doing it.
She didn't ask about it.
Roy was grateful for that.
Ed noticed in his lecture.
He was twelve minutes early, settled into his seat, notes open and ready to go. When he flipped to page fourteen he instead, found page thirteen and then page fifteen with nothing in between. He went back through the stack, checked again.
Page fourteen was not there.
The collision.
Obviously.
Ed let out a sigh, he’d been in too much of a hurry to count.
He wrote at the top of page thirteen: p.14 MISSING, rewrite tonight. Then he put the cap back on his pen. It was annoying. It would take an hour, maybe less. He knew the mechanism; he'd just have to sit down and re-derive it. He sighed, this was fine. Not a disaster, just annoying.
He watched Professor Marcoh start writing on the board and let his mind settle back into the lecture.
What came back, intermittently, wasn't really the missing page. It was more the guy. The way he'd slowed down when he spoke, not the exaggerated performance some people did where every syllable got its own moment, just a natural half-step back. Almost like he'd registered something and adjusted without making a thing of it. Ed had noticed, of course. He usually noticed everything. Most people either didn't register anything at all or went too far the other direction, mouthing at him like he was very far away. This had been neither.
He filed it away and went back to Marcoh.
The thing people didn't understand about Ed's deafness, the thing he'd stopped trying to explain by the time he was ten, was that he remembered hearing.
Not well, not completely.
The memories had the soft, imprecise quality of things from early childhood, more texture than detail. He remembered the sound of rain on the roof of the house in Resembool. He remembered his mother singing, though he couldn't reproduce the melody even in his head anymore. He remembered the particular creak of the third stair and the way Al used to call his name from another room, high and clear, before Ed had learned to watch for him instead.
He had been four when he got sick.
It had started as an ear infection, both ears at once, which his mother had taken him to the doctor for. The doctor had prescribed antibiotics and sent them home, and for a few days it seemed like it was working. But then, all of sudden it wasn't. The fever came back higher than before, and then higher than that, and Ed remembered, in the fragmentary sensory way of very early childhood and hazy, lying on the couch under a blanket in the middle of the afternoon feeling wrong in a way he didn't have words for. His head hurt so badly he couldn't lift it, his neck hurt, everything hurt. He remembered his mother's hand on his forehead, soft and gentle. Her face going still in a way that frightened him more than the pain did.
The drive to the hospital was something he remembered in bits and pieces. Being put in the car seat, the streetlights going past the window, his mother's voice tight and fast on her phone but he didn’t know who she was talking to. He remembered the hospital being very bright and very loud and people moving around him quickly in a way that made everything worse. He remembered a needle and crying and his mother's face right next to his saying something he couldn't make out through the noise, and then a long blank space.
What the doctors told his mother, what she told Ed years later in pieces when he was old enough to understand, was that the bacteria from the ear infections had spread. Crossed into his meninges. Bacterial meningitis, severe enough that there had been a point, somewhere in the first forty-eight hours, where they had not been sure if he’d make it through.
He had almost died.
He understood this as a fact but not quite as a reality, the way you understood things that had happened to a version of you too young to have processed them. Too young for it all to be painful or scary.
He had been in the hospital for almost two weeks. Al and Winry hadn't been allowed to visit, too young, too much risk of exposure because they weren’t sure if it was the contagious kind. Ed remembered with the specific ache of a four-year-old's logic not understanding why they weren't there. He wanted them there, he missed them. He'd asked for Al, probably a thousand times. His mother had told him later that she'd had to call Pinako Rockbell every day with updates, and that Al and Winry had stood by the phone for every call.
His mother had slept in the chair beside his bed every night. He remembered that very clearly. Not her face exactly, but the shape of her there, always there, every time he woke up frightened and disoriented. The feeling of her hand finding his in the dark, soft and warm.
She must have been terrified. He understood that now as an adult, in a way he hadn't been able to at four. She had sat in that room with her sick child and managed her fear somewhere he couldn't see it and had been calm and steady and present every single time he needed her to be. He didn't know how she'd done it. He suspected he would never fully know.
Ed went home with an IV still in his arm, taped under a padded red cast that ran from his wrist to his elbow to protect it. He remembered how strange it had felt, the weight of it, the way it caught on his blankets at night. And Ed remembered Al standing in the doorway of his bedroom when they brought him home, Al who had been waiting, who had been so patient, going very still at the sight of him.
Al had been scared.
He hadn't known how to say so. He was barely three, and Ed was his older brother, and Ed had been gone for almost two weeks and had come back looking different with something attached to his arm and their mother hovering. Al had stood in the doorway for a long moment and then gone to his own room without saying anything, and Ed had been too exhausted to understand why.
It was their mother who had explained it later. Al was scared of hurting him. Al thought the cast meant Ed would break.
It had taken almost a week, of Ed being home and being in the same space and Al watching from a cautious distance before Al had climbed into Ed's bed one morning without asking and pressed his small face against Ed's shoulder and stayed there. Ed had put his arm around him. They didn’t talk about it. They didn’t need to.
Winry had come over the first Saturday after Ed got home, and she had taken one look at him from across the living room and burst into tears. Not quiet tears, the full gulping four-year-old variety, completely uncontrolled. Her grandmother had tried to comfort her and Winry had cried even harder. Ed had been so alarmed that he'd forgotten to feel bad for himself.
He didn't remember going back to preschool that year. He never ended going back. By the time he was well enough to leave the house, the school year was almost over. That’s when everything felt muffled and wrong and exhausting to navigate. Ed wasn't ready. Nobody pushed him.
Because that was the other thing, the hearing.
In the hospital, coming in and out of sleep, he'd noticed that things were quieter than they should have been. He'd thought for a while that it was the medicine, or the room, or something temporary. Ed asked his mother why everything sounded far away and she'd said, gently, that the doctors were keeping an eye on it.
At home it became undeniable. Sounds he'd always known, the television, the kitchen, Al's voice from another room, were muffled now, like he was hearing it through water. Some things were gone entirely. Ed kept turning his head, trying to find angles where things came in more clearly.
He remembered being frightened in a way that was different from the hospital fear. The hospital fear had been large and immediate. This fear was smaller and constant, a steady low-grade wrongness that followed him from room to room. He didn't have the words for it. He was just four years old. He just knew that something had been taken out of the world and he didn't know if it was coming back.
His mother had sat with him through that too. She hadn't pretended it was fine. She'd sat next to him on the bed and said, “Something happened to your ears when you were sick. Your hearing isn't the same.” And then she'd waited for his questions, however many there were, and answered every one.
He'd asked, “will it come back?”
His Mother just smiled gently at him, and She'd said, “we don't know yet. But we're going to figure out what helps.”
That was how she'd been about all of it. Not falsely bright, not devastated, not making it bigger or smaller than it was. Just steady. Here. We will figure out what helps.
Ed had not understood until he was much older what it must have cost her to be that steady.
For a while after, he'd still had something: a narrow frequency window, sounds loud enough or low enough to register as vibration more than hearing, but enough that regular hearing aids helped. Ed spent several years with them, calibrating, learning to read lips alongside the partial signal, building the layered system of attention that he'd carried ever since.
By age seven, it was mostly gone. By age eight, it was gone entirely.
The cochlear implant surgery had happened two weeks before his ninth birthday. After the hearing loss became total they had moved quickly, as there was a risk that the cochlea could ossify after meningitis: scar tissue forming around the structures the electrodes needed to reach, and the window for successful implantation could close. There had been imaging and assessments and an evaluation period that had felt, to an eight-year-old, extremely long, but had in medical terms been fast. A different hospital, a different kind of fear, older and more aware. Ed remembered it all very clearly. He remembered the smell and the weight of the surgical gown and his mother holding both his hands while the anesthesiologist explained what was going to happen. He remembered Al in the waiting room, seven years old and old enough to be there this time, sitting for four hours with a library book he hadn't opened, and how their Mother had told him about it afterward.
Ed remembered waking up after the surgery. He remembered the bandages and the disorientation and the long careful weeks of mapping and calibration after, the audiologist adjusting frequencies while Ed tried to explain what he was hearing and the language for it kept failing him. He remembered the first time a sound came in clearly through the processor and he'd cried without meaning to, not from joy exactly but from something more complicated: the recognition of something he'd almost forgotten, changed almost beyond recognition, coming back.
The processors were not his ears. He knew that. The external processor picked up sound and converted it to a digital signal, which the transmitter coil sent through the skin to the internal implant, which then sent electrical impulses to the electrodes in his cochlea, which stimulated the auditory nerve, which sent signals to the brain. Ed understood the science of it all. His brain had learned, over years of auditory training and practice, to interpret those signals as something close to hearing. Close, but not identical. Music came in flatter. Certain voices smeared in reverberant spaces. Background noise was a constant negotiation.
But he could hear. Imperfectly. With effort. More than he'd been able to at eight, and he had never once taken that for granted.
Ed also remembered what it had felt like before any of it, those first four years when the world had simply had sound in it, and that memory sat in him like a compass point. Not grief exactly, just orientation. The knowledge of what had been lost, what had been rebuilt and how much of both he carried.
He thought about it sometimes when he was in a new place, the automatic sweep he'd been running for years.
Most people never noticed.
That was, generally, the point.
