A.N. - Hello! This is my first My Hero Academia fanfiction, so I hope you'll be kind in judging it!

I've really wanted a Dabi/Touya and Shouto interaction set after the Chapter 290 reveal, and not finding one that I liked enough, I decided to write to my own! Hope you enjoy!

Also, I couldn't decide how I wanted to refer to Dabi/Touya, and how Shouto would refer to him, so in the text (and Shouto's mind) it goes back and forth with references to both Dabi and Touya.

Would you mind if I killed you?
Would you mind if I tried to?
- "What Have You Done Now," Within Temptation

Todoroki Shouto woke up to a hand over his mouth.

Any lingering sleepiness disappeared immediately as his eyes widened, taking in the person looming above him. A tall, lithe figure with dark hair sat beside his futon, staring down at him with bright blue eyes. A cruel smile twisted his features, already marred by dark, purplish burn scars and silver staples, barely keeping his skin together.

"Good morning, Shouto," Dabi - no, he told you his name is Touya - said. "Did you sleep well?"

Ice sprang up from the floor and encased the intruder. Touya's smile grew wider as his body suddenly burst into blue flames, melting the ice; cold water puddled on the floor and seeped into the futon. Shouto had no time to worry about the furniture, however.

"Relax, kid," Touya chided. "I'm not here to fight. But we both know I'd win, especially since I don't care what or who gets burned in this building. So just be a good boy for now, alright?"

Shouto grit his teeth, but he couldn't argue with that logic. Touya's - Dabi's? - flames could beat both his ice and fire powers, and he had no qualms about collateral damage, whereas Shouto had all his classmates and who knows how many service workers were in the U.A. 1-A dorms right now to worry about.

What are you here for? Shouto wanted to ask, but his brother was still covering his mouth.

Just then there was a knock on Shouto's door. Both Todorokis turned towards it, panic welling inside Shouto at the thought of one his classmates in the path of danger.

"Hey, Todoroki!" It was Sero's voice. "You up yet? We're gonna be late for class!"

Were they? What time was it? How could Shouto have slept in so long? He wished he could see the clock he had on the table pushed against the wall, but he didn't dare look away from the villain in front of him for too long.

Another knock. "Hey, Todoroki? You in there?" Sero asked. Then, in a quieter voice, as if talking to someone else, "Are you sure he didn't just head over early, Satou? You know how responsible he is."

"I've been awake for a while and didn't see him," came Satou's reply. "But, I mean, he could be. He probably did go over early."

Shouto gazed at Touya, who was frowning slightly. He must be thinking the same thing as Shouto: if Sero and Satou went to class and didn't see Shouto, they would realize something was wrong since he hadn't responded to them now.

Finally Touya turned back to Shouto. "Answer them," he ordered in a quiet voice. "But, you know..." He brought a finger to his lips and lit it on fire, the blue flames dancing along his fingertip. When Shouto nodded in understanding, he pulled his hand away from Shouto's mouth.

"I - " Shouto coughed a bit, his throat dry. "I'm not - I'm not feeling that well, actually, Satou, Sero. Go on without me."

"Oh!" Sero exclaimed. "Oh, that sucks, sorry, man." There was a pause, then some whispering, before he added, "You need us to get you anything? Medicine or soup or something? We could come in - "

"No!" Shouto replied, a little too forceful, even to his own ears. "I - I mean, no, thank-you. I'll be fine. Just...tell Aizawa-sensei I'll try to be down when I can."

"Okay. Feel better, man," Sero replied after another pause.

"See you later, Todoroki," Satou put in. "Text us if you need anything."

Shouto said nothing, only releasing a relieved breath when he heard his classmates' footsteps carry them down the hall and away from his room. His brother looked down at him - he was still far too close for comfort, leaning over Shouto in a way that made him think of a vulture or some other bird of prey.

"Well, aren't you lucky to have such caring friends," Touya said lightly, though his eyes were narrowed.

Shouto said nothing, trying to school his features. His heart beat rapidly in his chest and his breaths were shorter than he would like. Eventually, he managed,

"What do you want, Touya? Why are you here?"

Touya stared at him for a moment longer, before he leaned back, stretching his arms behind him for support. An unsettling grin spread across his face. "Aww, you know. I just wanted to come and see you, little brother. Is that not allowed?"

Shouto frowned. Slowly, carefully, he sat up, scooting back out of his blankets. He wanted as much space between him and Dabi as he could get. "How did you get in here?"

"Don't worry about it."

Well, that was helpful. But it's not like Shouto expected a real answer.

The two brothers stared at each other for a long moment, before Shouto said slowly, "Last time we saw each other...you wanted to kill me."

The last time they saw each other had been during the war against the League of Villains - technically the Paranormal Liberation Front, but everyone knew who the real force behind the PLF had been during that time. The memory of searing heat and deep, heart-wrenching grief returned to Shouto's mind, and he shuddered.

The reveal that his older brother, long thought dead, was actually alive, and was a murderous villain, and was working with the League of Villains, had been almost too much to bear. His father, the Number One Hero Endeavor, had been practically catatonic, even before he passed out from his wounds. Shouto had tried desperately to protect him from Touya - no, he was Dabi then - and his mad rage. In the end, it wasn't anything he'd done to keep his father and his friends and the other pro heroes safe; what had saved them was the League of Villains' decision to retreat and Dabi's desire to kill himself and Shouto right in front of their father.

"Enji Todoroki isn't completely broken yet. If he passes out now, there's no point in going on with this little performance. Sorry, masterpiece."

Those were the last words Touya had said to Shouto before blasting him away with his fire and disappearing.

And now, a few months later, he had broken into Shouto's dorm room.

What was he to make of that?

Dabi chuckled, which did not put Shouto at ease. "Yeah, that's true. It still is true, a little bit." Then his face lit up with manic glee. "Do you remember, Shouto? Do you remember how warm it was? What a blaze we made! What a scene!" He threw his head back and laughed, as if high off the memory of trying to burn himself and his younger brother alive.

Shouto winced as his brother's laughter echoed around the room. His arm began to shake and quickly he grabbed it with his other hand, not wanting to let Dabi see. Of course he remembered - how could he ever forget the feeling of being stuck in an inferno, of being wrapped in his brother's cruel embrace, of blue flames savaging his skin for fuel? He didn't want to dwell on it, no less twice barely five minutes apart. It was bad enough he experienced it all over again in his dreams -

Ah. Maybe that explained why he had slept in so late. He'd been having trouble staying asleep so he finally took some of the sleeping pills that Recovery Girl had prescribed him last month. He might have taken one or two more than he was supposed to, but at least he'd slept soundly.

Until he'd woken up to his own personal nightmare, that is.

Fingers grazed the back of his neck, and Shouto snapped back to attention. Touya had reached behind him and pulled Shouto forward, smacking him against Touya's chest. Shouto's breath hitched, even as he cursed himself for not paying attention. There was a villain in front of him - he couldn't lose focus so easily!

"Do you think we'll be able to hear him?" Touya asked, voice now calm. Shouto couldn't respond - his face was pressed too tightly against Touya's chest, Touya's fingers now tangled in his hair. Touya didn't seem to care, however, as he continued, "Endeavor, I mean. The old bastard. When he screams and cries in despair , do you think we'll be able to hear him from Hell?" Then he giggled - clearly the last bits of his mania hadn't yet faded. "I mean, I know I'm going to Hell, and I know he is. But you're a hero, aren't you, masterpiece? Just like you're supposed to be. Maybe Yama will be good to you and let you reincarnate into something nice."

Shouto's breaths came out shorter and shorter. His heartbeat rang in his ears. Being this close to his brother again was making him hyperventilate. What was Touya - what was Dabi doing? Had he come here to finish Shouto off? But their father wasn't here to see it. Unless he no longer wanted an audience? Did he want to weaken the credibility of U.A. and the hero society even more by making an example of them? By showing that he was able to kill one of their students in their own dormitories? The school would never be able to recover then.

Touya fell quiet. The only sounds were Shouto's ragged breathing and his pulse thumping in his ears. After a while, however, even that slowed. Finally, he could hear Touya's own heartbeat, slow and steady. In any other circumstance, it might be nice - soothing even. In another life, in another family, they might have sat just like this. Maybe Touya could have comforted him after a nightmare this way. They weren't so different, Shouto knew - it was part of what drove Touya to become Dabi - he'd craved their father's recognition and attention even when it hurt him, and Shouto had only ever wanted Endeavor to stop hurting him.

In this life, it seemed like hurting each other was all their family was good at - his father, his mother, his brother. Even Natsuo with his pent up frustration and rage, the kind that made Fuyumi cry and Shouto wonder whether he was a bad brother for even thinking of forgiving Endeavor. And Fuyumi, with her desperate pleas and well-intentioned manipulations, eager to please the father who'd abused them even at the expense of her brothers' mental health.

What a mess the Todorokis were. Bad enough when just he knew it, but now the whole world did, thanks to Dabi.

Dabi, who at least for now simply held him. Shouto tried to clear his thoughts. He didn't know how much time had passed, didn't know when his classmates would be returning. Hopefully Dabi would be gone by then.

Hopefully Shouto would still be here.

After a few minutes, that felt like hours - or was it the other way around? - Shouto tried to move. He inched his head backwards, pushing against his brother's hold. There was a slight give, before Touya tightened his grip once more and pushed Shouto back against him. Then, slowly, he released him. The message was clear - Shouto could get up now, but only because Touya had allowed it.

Shouto sucked in a deep gulp of air, able to breathe freely now. He backed away from Touya until he was up against the fake sliding door he'd installed in his room the first day they moved in. Touya watched him with his bright blue eyes, the same as Endeavor's and Shouto's left. He smiled lazily at him, before it morphed it something more serious.

"But, you know, Shouto," Touya started, "I've been thinking. About another way you and I could destroy Endeavor."

Shouto tensed at those words. What was he planning now? What did Shouto have to do with it?

Touya leaned forward, eyes wide. "Shouto. Come with me. Join the League and wreak havoc on this pitiless world. Hero society is a cancer - we can be the cure."

Shouto stared at him, startled. "What?"

Touya lunged towards him, landing on his hands and knees in front of Shouto, closing the gap between them once more. "Can't you see it, little brother? You and me, up against Endeavor - his failure and his masterpiece, working together. Wouldn't that be his worst nightmare!" A grin split his face, all teeth and malice, and Shouto swallowed. Touya was serious about this. This idea was better than wanting to burn Shouto to a crisp, but it still wasn't something Shouto was going to go along with.

Shouto closed his eyes and sighed. After a moment, he opened them again, gazing directly into Touya's eyes. "Touya, I know why you're hurting. Why you're so furious. And if you want to hate Father forever for what he did...that's fine. I don't...think it's good for you, or for the family, for you to hold onto all that rage and hate...but I understand." Shouto paused, gathering his thoughts. Touya stared at him, hanging on to his every word.

"And I...I think differently. I want to see...how he changes. What kind of father, and hero, and man, he'll be. I want to know...if it's possible." Shouto paused again, then took another deep breath. He clenched his hands into fists by his sides.

"Like I said, I understand your anger. But...you haven't just hurt Endeavor. You've killed innocent people. Plotted with villains, and destroyed cities, and put people in danger. And I can't condone that. I can't join you when you're like that, and I will never join the League of Villains."

Touya drew back, settling into a sitting position, legs crossed. He was quiet for a moment, processing Shouto's words. Finally, he said, "That's your answer?"

Shouto nodded. "That's my answer."

Touya nodded slowly. "And...if I refuse to accept that?"

Shouto blinked owlishly at him. "What - what do you mean? Would you, what, kidnap me? Like Bakugou? You know how well that went, that time."

Touya cracked a grin, eyes wide with amusement. "Ha, that's true. And you were there that time, weren't you, little Shouto? I suppose that means your friends would return the favor for you, ne?"

He stood then, fluidly rising to his feet. Shouto scrambled up in response, body tense, shifting into a fighting stance.

Dabi grinned fully at that, then stretched his limbs, casual as could be. "Mah. I guess this means the next time we see each other will be on the battlefield, baby brother." His grin softened by the smallest degree. "You can tell Fuyumi and Natsu hello for me, if you want. But no one else, 'kay?"

Then, before Shouto could react, Dabi flicked something at him. It was small, about the size of a marble, and it hit him squarely in the forehead. As Shouto flinched from the pain, his eyes widened when a light brown colored smoke escaped from the orb. It surrounded him, rushing into his nose and mouth as he coughed. He tried to cover his face with his sleeve, but it was too late; he was already woozy.

No...no, I can't let this happen! I can't let him take me!

But his brother's grinning face was the last thing Shouto saw before he blacked out.

...

Consciousness filtered in slowly. Shouto blinked a few times, trying to adjust to the light. Then, the memory of what occurred before he passed out came back to him.

Touya...asking him to join the League...the brown smoke...

Shouto shot up with a gasp, glancing frantically at his surroundings. To his great relief, though also confusion, he was still in his dorm room. Familiar Japanese-style furniture stared back at him, seeming no different than it had this morning.

Shouto groaned as he felt his head; something was pounding against it, as if trying to break free. But he couldn't just lay here. He needed to tell Aizawa-sensei, or All Might-sensei, or Principal Nezu - someone - that a villain had broken into his dorm.

Shouto scrambled off his futon - had Touya tucked him in before he left? The thought was a little bit cute but mostly disturbing - and dashed to his door, ripping it open.

He nearly tripped over several things lying in front of his room. Shouto frowned in confusion as he looked down. A hot drink thermos, a foil covered bowl, a plate with a piece of cake on it, and a couple bottles of pain reliever. There was also a note on top of the thermos. Shouto reached down and read it.

Hey Todoroki! To help you feel better, Satou made some cake, Yaoyorozu made some hot soup, and Midoriya made cold soba for you! Hope it helps! - Sero.

Warmth flowed through Shouto at the words. He looked up and down the hall, but there was no one about. He had no idea what time it was, again, so maybe everyone was in bed now.

What a difference a year and a half made - he'd come into U.A. hell bent on becoming stronger in order to spite his father, but he'd ended up with friends that were almost as good as a second family - better than family, even, in his case.

Shouto frowned then as he thought about his brother's "visit". His resolve to become a hero had never been in doubt, especially after seeing what destruction villains were capable of, but now he knew he needed to become even stronger. If Dabi could casually sneak into his room and defeat him so easily, who knows what could happen to his classmates? What if his brother actually refused to accept his "no" for an answer and returned to harass him? Not that Class 1-A was weak - not by any means - but Shouto would hate to be the reason they were put into any danger.

Shouto took his classmates' offerings into his room and placed them on his table. Then he carefully closed and locked his door and headed to the elevator. All Might-sensei, if no one else, was probably still up at school, and he would be the perfect person to tell.

"The next time we see each other will be on the battlefield, baby brother."

Then so be it, Touya-nii-san, Shouto thought. And when that time comes...

I'll be ready for you.

A.N. - And there you have it! What do you think? Constructive criticism welcome!

I hope I haven't made Shouto seem too weak here. I just think, one, he'd be super caught off guard by Dabi/Touya's appearance, plus what Dabi says in the beginning of the story; Shouto wouldn't want to get into a battle in the dorm rooms because he'd be worried about all that collateral damage, especially with their types of Quirks. I also think that Shouto may not truly want to fight his brother, but he will if he has to.

Anyway, thanks for reading. Stay safe and healthy, and I hope you have a wonderful Christmas, happy New Year, and Happy Holidays!
