A/N: So Big Hero 6 is my favorite movie in existence and I just had to do something for it. Yes, this trope is so overused at this point but I DON'T CARE I'm doing it anyway! Yes, it's Alive!Tadashi because you can't just kill off a character like that. You can't. So Tadashi is alive. How? Well the story will explain all. Please leave a review after you're done so that I know what to fix, what you liked/disliked, etc. This movie has meant so much to me personally and I'm on an inspiration kick from it so I'm excited to share with you all. Sorry if it seems a little choppy. This is my exposition chapter and I've got so much cold medicine in my veins right now… O.O

"Why are you bothering with this, Hiro? You're wasting your time." Go Go snapped her bubblegum, tried to look disinterested to hide her concern.

Hiro took a deep breath, the jail suddenly seeming much, much bigger than he remembered.

"Go Go's right, Hiro," Honey Lemon said gently. "What are you going to accomplish?"

"He's going to answer for what he did," Hiro fixed them with a determined glare.

"But he is! He's in there! He's locked up!" Honey Lemon pleaded with the boy.

"What are you going to do? Hurt his feelings? He has none. This is pointless. It won't bring Tadashi back," Go Go added.

"I'm going," the boy waved them off. "Whether you want me to or not. He's going to remember Tadashi. He's going to be haunted by it every night," he gritted out. He left the girls behind, shoving open the prison's glass door and walking into its lobby.

The room was spare, covered in crusty beige carpet that made Hiro wonder whether or not beige was the original color. The walls were yellowed with age. A bored-looking attendant sat the desk.

"You here for something, kid?" he asked.

"I'm here to see someone," Hiro ground out slowly.

"Sign in," the desk attendant shoved a clipboard to him. "What's the name?"

"Robert Callaghan," he uttered the name with disgust.

The man frowned and Hiro leveled him with a moody stare. "He is allowed to have visitors, right?"

"Yes of course," the man replied quickly. "It's just that he's been here for almost a year now without receiving any. You his kid or something?"

"Distant relative," Hiro lied. "Tell him Hiro Hamada is here to see him."

The man picked up the phone and dialed a number. "Tell Callaghan he has a visitor. Some kid claiming to be a distant relative. Name's Hiro Hamada." He paused, then hung up the phone. "Callaghan will be out shortly. Follow me," he said as he led Hiro through a doorway to the visiting room. There was a table with two chairs opposite each other but nothing else to speak of. Hiro sat down, suddenly feeling a little nervous but nonetheless determined. He wondered how Callaghan would react. Would he act like he'd seen a ghost? Perhaps he would break down or beg forgiveness. Or maybe he wouldn't react at all, stunned to see the brother of his former star pupil sitting there. The brother of the star pupil he murdered.

Two guards led Callaghan through a separate door. He was clad in orange prison jumpers. He did not look surprised to see Hiro sitting there as the guards sat him down and cuffed his hands to the table. "We'll be right outside the door," one of them said. "Shout if you need anything." And with that, Hiro found himself alone in a room with his brother's murderer.

"Hiro Hamada," Callaghan acknowledged in a calm way that made Hiro's blood boil.

"Don't use my name," the boy ground out, unable to think of anything to say in response to the man's nonchalant greeting. He just didn't want to hear his name coming out of that murderer's mouth. Especially not the last name he shared with his brother.

"What can I do for you," Callaghan began again casually.

"Shut up!" the fourteen year old stood up abruptly, slamming his palms down on the table and glaring straight into the professor's face. "You! You killed Tadashi! Because of you, my brother's dead. You're a murderer, Callaghan. A murderer," Hiro jabbed a finger at the convict. "And I hope that every time you close your eyes all you can see is Tadashi! I hope you don't sleep because of him!" Tears of rage began to build in his eyes. "I hope that his death haunts you every day of you miserable existence."

Hiro sighed, collapsing in his chair and suddenly feeling very drained. That was all he had planned to say and yet he felt that he hadn't said it all.

"I'm not a monster," Callaghan spoke quietly.

Anger flashed across the boy's face as he sneered, "you're not a monster? My brother went into that burning building to save you from the fire you started. He died when you didn't even need saving and you're not a monster?"

Callaghan raised his voice for the first time. "Is that what you think? That I killed Tadashi? That I murdered your brother, my star pupil? Let me tell you something Hiro. Tadashi is alive and breathing. I saved him from that fire. I swarmed the microbots around him to protect him. Your brother is alive because of me."

"You're lying," Hiro seethed quietly. "You're LYING!" he said even more loudly. "Tadashi is DEAD!" He pounded the table again, causing the guards to rush into the room. The boy paid them no mind. "If he was alive, he would have come back to me by now," he finished quietly, chocking back a sob. How dare Callaghan tease him like this? All he wanted was his big brother back, and he knew it was impossible but here was this man, this monster trying to give him false hope.

"He helped me reengineer the portal, Hiro," Callaghan spoke up softly again. "I couldn't have done it myself that quickly. He's alive. He used to expound on your big brain, use it! Logically—"

"SHUT UP!" Hiro interrupted, tears now flowing freely from his eyes. "Don't you ever talk about my brother again! How dare you! Tadashi would have never helped you!"

"Logically, could I have done all of this on my own?" Callaghan continued, ignoring the outburst. "Tadashi. Is. Alive. He's on the island where you nearly killed me. Don't believe me? Go see for yourself."

"Get him away from me," Hiro growled to the guards, wiping the tears that blurred his vision as they uncuffed him from the table and hauled him to his feet.

"I'm not a monster, Hiro," Callaghan repeated as he was led from the room.

Hiro's face tightened into a grim scowl. "But you are," he muttered.

A/N: Okay so there's my exposition/teaser/trailer thing. Let me know if I should continue! I have some plans for what could happen next. If this does get continued, it will probably span maybe two or three more chapters at most but please leave a review and tell me what you think! I have a larger Big Hero 6 multichapter fic in the works. Thanks!
