This is a little AU suggested by my very dear friend in which Hiro was the one that died in the fire, not Tadashi and Tadashi continues to have very much angst. I present to you an angsty Tadashi.

"I need to find Callahan."

"Wait, there has to be a better option!" He shouted, voice cracking as Tadashi pulled away from him. "Stop! I have a better solution! My microbots are inside. They can block fire. Let me save him." Tadashi looked unsure, his feet will ready to race into the inferno. "Trust me Tadashi."

Before he could say anything, Hiro dashed past him, tripping him and then bolting through the doors. Tadashi got up, stumbling and cutting himself on the gravel. He ran towards the building.

"HIRO!"

The world went white.

¥•

His body had been too damaged for it to be open casket. It took them 20 minutes to put out the fire, and 3 hours to move all the rubble and remove his body. As the building exploded, the roof caved in and everything fell into a giant heap. They found his body under what was left of the ceiling; broken pieces of metal and wood.

He had been going through the motions up until that point. He went to the lab and worked through the night, long after all the others had left. He came home only for showers and what he couldn't even call a meal. They others, Gogo, Fred, Honey, Wasabi, they tried to talk to him, but he would just shake his head and continue on with calculations.

When he slept, usually on his project board, he would dream of the fire. He would see red, only red. The burning hot flames of death. And then he would hear Hiro's voice. It would be crying out to him. Just like when he was a kid and Hiro got stuck in a tree, or skinned his knee. He knew that cry, it was when he would always comfort him.

He would run blindly towards that voice, but he could see nothing, was he even moving? And then, burning all around him and nothing but burning was felt.

He would wake up in a cold sweat, falling to the ground, only to get back up and with sleep dragging at his soul, he would continue to work, stopping only to use the restroom and other necessities.

The day of the funeral, it was raining. How cliche right? Ater they lowered his casket in the ground, and everyone said kind words about his brother, Tadashi took off. He ran all the way back to the café, knowing the path from the cemetery well, shoving the thoughts that clouded his mind to the back of his head.

The rain completely drenched him, effectively causing him to be distracted from all other thoughts. As he opened the door, the heat was welcome and needed. He walked up he stairs, leaving his shoes on top of the vents to dry and then hanging his jacket on the bathroom door. He walked into his room, eyes trained on his feet and went to sit on his bed. All he wanted to do was sleep, but he couldn't. He sat on his bed, wet clothes and all, and put his head in his hands closing his eyes tightly.

A while later, he couldn't tell time at this point, he opened his eyes and looked down at the reflection of himself in the puddle of water formed by his soaked clothes. Sighing, he stood up to retrieve a towel from the bathroom when he slipped on the puddle right in front of his and slammed his little toe against the end of his dresser.

Tadashi swore and kicked the dresser as hard as he could, upsetting everything on top of it, and more than likely ruining the walk as well. This set of another chain of curses and a cup full of pencils scattered all onto the floor, followed by a huge stack of papers and binders, and ended neatly with his alarm crashing to the ground and ringing so obnoxiously loudly.

As it hit the floor, it only infuriated him more. He picked it up and flung it against the wall with all his might, finding a marvelously satisfying feeling as the clock burst against the wall, little metal bits settling down to rest on the floor.

Still filled with anger, Tadashi barely hesitated before throwing whatever was in arms reach at the wall.

Last year's showcase item, a self sustaining plant that gave off twice the amount of oxygen gave a lovely crack.

His nano tech that was still in progress, sitting on his shelf waiting for a spare moment, it burst out of its container so nicely, falling softly to the floor.

The picture frame with his graduation certificate.

A glass of water that had been full before he left.

Trophies left over from his childhood games.

Tadashi let his anger flow as he smashed everything he once thought permanent. He stopped though, a second before releasing when he got to the bowl.

It was one of those bowls you made in elementary school out of the cheap clay; your parents would gush over it and then use it for a keys holder or jewelry or something. Hiro had made it for him about 2 years after their parents had died. Tadashi clutched the object to his chest, falling to his knees, and began to cry.

He hadn't believed any of them. The paramedics, the firefighters, the doctors, his friends, aunt Cass. He didn't want to believe them. He was so angry, and now he couldn't stop crying. Why was he crying when he was angry.

Tadashi was still crying when he heard the familiar inflating sound.

"Hello, I am Baymax-"

"Power down Baymax." His voice as scratchy and raw. He sounded pitiful.

"I am your personal healthcare-"

"Alpha protocol 421 Power down."

"Companion. I heard-"

"ALPHA PROTOCOL 421 SHUT DOWN"

"A sound of-"

"AHHH" Tadashi screamed, throwing the bowl at the robot's head, effectively shattering the bowl and puncturing the robot's vinyl skin in many places.

"Just go back to your charging station." Tadashi choked out, curling up against the wall, chest heaving, tears pouring out even faster now. There was a sound of rubber against rubber, hissing and then it was silent again.

Rain fell down on the café , steady, unending; a perfect harmony in the chaos of this world between here and there.

A/N- Sorry for not updating for the past few days, I've been writing down all these stories to type up, but it takes time and I have so many other things on my plate. I hope you enjoy this though! I think this is my longest chapter in here yet, so I hope you enjoy this lovely chapter.

Thanks go to sebastuan who has brought this prompt into my brain in math class when I'm supposed to be studying.
