His Big Brother came back. Smiling wide, Little Brother got up from his warm bed to hug his Big Brother. His Big Brother loved it when Little Brother gave him hugs.

"Ah, Little Brother, I see you're up." Big Brother smiled back, just as wide as Little Brother's, as he wrapped his own arms around Little Brother.

"I missed you." Little Brother said, his voice soft from disuse. It was okay. Little Brother only needed to talk whenever Big Brother was around.

Big Brother's smile widened more.

~~It was creepy.~~

It warmed Little Brother's heart. He was always happy to make Big Brother happy.

"I missed you too." Big Brother hummed. "Little Brother?"

Little Brother tilted his head. "Yes Big Brother?"

"Do you love me?"

Little Brother froze. Of course he loved his Big Brother! Why would Big Brother ask him such a silly question?

"Well?" Big Brother asked, his grip tightening.

He couldn't answer. Why wouldn't he answer? It was a simple answer why wasn't Little ~~Izuku~~ Brother answering the question.

"I-I-I-" ~~Izuku~~ Little Brother stuttered. He- he-

A large hand on his head. Pain. Screaming.

He loves his Big Brother. He will never leave his Big Brother. He will listen to his Big Brother. He will tell his Big Brother how much he loves him.

Little Brother wasn't always with Big Brother. Little Brother doesn't remember much, but Big Brother does his best to help Little Brother out. After all, Big Brothers are meant to help their Little Brothers.

Like right then. Little Brother came down with a cold. He wasn't careful even though he knew he could get sick easily. That's why his Big Brother was helping him eat nice warm soup.

"It's not too hot is it?" Big Brother asked gently after Little Brother had his first bite.

Little Brother didn't even have to think about it as he shook his head for a no. "It's just right." He softly said. "It's really good. Thank you Big Brother."

He saw his Big Brother smile. "I'm glad. After this would you like me to read you something? You used to love it when we read together when you were sick like this back when we were younger."

Little Brother didn't remember that. It was very kind of Big Brother to tell Little Brother about how things were, back in that empty space in his head.

"Yes please." Little Brother nodded. A stray thought caused him to ask, "can it be comics? About superheroes?"

Big Brother's smile turned to ice.

~~It was scary it was awful it meant danger danger Izuku was in danger-~~

"Why heroes?" Big Brother asked, voice clipped.

His mouth moved on its own. "Because I want some to rescue me."

A large hand softly landed on his head. Pain. Screams.

He is a Little Brother. He has a Big Brother. Big Brother takes care of him. He is weak. Heroes do not exist. He did not need to be rescued. He was perfectly safe with his Big Brother.

He is a Little Brother. He has a Big Brother. Big Brother takes care of him. He is weak. He is pathetic. He is fragile. He is sickly. He is useless. He can't do anything. Heroes do not exist.

Fingers card through his hair. They do not get caught by any tangles. His hair is too smooth to get knots in them.

All is silent. Other than the sound of breathing. Of hearts beating. It was silent.

"Who are you?" A deep voice asks.

He does not speak.

The fingers roughly tug at his hair.

"I…zuku?" He tried.

A sharp shock ran through him. It hurt.

"Try again." The deep voice said.

He thought about the words that ran through earlier. "Little… Brother?"

Something soothing made the pain fly away.

"That's right." The voice praised. "You're my Little Brother."

That was right. He was Little Brother and Little Brother was a Little Brother.

Who was Izuku?

"No one important." The voice said.

Did Little Brother say that aloud? That wasn't good. But it was good to know that Izuku wasn't anyone important. Little Brother wouldn't dwell on who that person could be.

Who was Little Brother thinking of again?

"Who am I?" The voice asked again.

Oh. Little Brother was thinking of the voice. "Big… Brother?" He guessed.

A soft kiss on his forehead.

"That is correct." Big Brother praised once more.

Little Brother smiled. He had a name to the voice.

"Do you know what that means?" Big Brother went back to running his fingers through Little Brother's hair.

"That… you'll take care of me?"

"Yes. Can you tell me why?"

"I am weak. I am pathetic. I am fragile. I am sickly. I am useless. I can't do anything."

"You are correct, my Little Brother. And because you are all of that, it is my duty as your Big Brother to take good care of you. How kind of me to be your Big Brother, to protect you and keep you safe."

Little Brother nodded, smiling. "Yes, thank you Big Brother. You're very kind."

A deep warm feeling entered his bones, making him feel so comfortable. That, mixed with the fingers that still ran through his hair, made him melt in content.

"I love you, my Little Brother." Big Brother said.

"I love you too, Big Brother." Little Brother replied.

Little Brother loves his Big Brother. Big Brother was so kind to Little Brother. Big Brother helped remind Little Brother so many things.

"I need you to do something for me." Big Brother said, lifting Little Brother up into a sitting position on his bed. The nest of blankets pooled around Little Brother.

Little Brother looked at his Big Brother with mild confusion that was swiftly washed away. Big Brother pointed to a camera that had a light on. Was it recording?

"I need you to say your lines, my Little Brother."

Little Brother smiled. He'll gladly say his lines. His lines help remind him. How silly of him to have forgotten his lines earlier. His Big Brother was so kind to ask him questions to help him remember his lines. Little Brother was so lucky to have such a wonderful Big Brother.

So Little Brother nodded his head and spoke.

"I am a Little Brother. I have a Big Brother. Big Brother takes care of me. I am weak. I am pathetic. I am fragile. I am sickly. I am useless. I can't do anything. Heroes do not exist. I do not need to be rescued. I was perfectly safe with my Big Brother. I am so grateful to have a Big Brother that cares for me. I am so grateful that my Big Brother would keep me safe. I love my Big Brother. I will never leave my Big Brother. I will listen to my Big Brother. I will tell my Big Brother how much I love him."

"Again."

"Again"

"That's a good Little Brother. Now I want you to continue repeating that until I tell you to." Big Brother commanded.

And Little Brother repeated his mantra, as his Big Brother held him close, until his voice could no longer speak.

(And unknown to him, the heroes were forced to watch the whole thing, unable to save their lost student.)

So uh, some time ago McFaneLy and I were talking about different ways AFO could basically torture Izuku and today I thought back to it and went. "I'm going to write a small thing about that." And like an actual madman I managed to do it. (The joke here kids is that I actually wrote a small fic and posted it on the same day. Crazy am I right?)

But anyway welcome to Brother For One where All For One uses Izuku as a way to get his brother back.

(Also on AO3 and Wattpad. Oh and since I cannot find the strikeout function on here, the ~~ are to represent what words are crossed out since those are bad thoughts for a little brother to have ;))
