Hello! Here is that one-shot I promised my readers. Hope you like it. In this Tadashi is about 15 or 16 and Hiro is 11.

Disclaimer: I do not own Big Hero 6. If I did Tadashi would still be alive.

Tadashi was sitting on his bed trying to read a book for school. The thing was that he just couldn't. For one it wasn't a good book; it was a textbook, and not an interesting one like his Anatomy book, it was his Civics book. It also didn't help that, on the other side of the room, his little brother Hiro was banging his head, loudly, on his desk.

At first Tadashi had just ignored it, thinking he had just dropped something, but after it happened again he looked up from his book and over at his brother, to find him with his head on his desk. Not thinking anything of it he returned to his book. That is until he heard it again. Deciding that he would check on Hiro, as he couldn't focus anyways, Tadashi stood up and made his way over to his little brother's side of the room. When he got over to the 11 year old's desk he found him lifting his head up to bang it back down next to his algebra 2 book. There was a loud bang from the desk as Hiro's head collided yet again with the desk.

"Hiro! What are you doing?!" Tadashi said worriedly as he came up to the boy.

Hiro mumbled his answer, "So, stupid. Stupid, stupid, stupid," he punctuated each stupid with another bang of his head. Tadashi suddenly understood. As he was struggling to read his Civics book on one side of the room his little brother was on the other side struggling with Algebra 2, which he had to admit was very hard, it had even seemed to stump his genius of a little brother.

"Ok. Stop it." Hiro slammed his head down again and Tadashi exasperatedly said, "Hiro, stop it. I'll help you with your work, if you like." That was the wrong thing to say though. Hiro hated asking for or accepting help, that must have come from being the youngest and smartest kid in the entire school. Tadashi walked behind Hiro's chair and went to grab his head but before he could Hiro hit his head on his desk one more time, this time the sound on his skull colliding with the desk resonated around the room with a very large bang and a crack, that seriously scared Tadashi.

"Hiro!" Tadashi half groaned half yelled. Hiro didn't answer though and after a minute of this Tadashi lifted Hiro's head on the desk and saw his eyes were closed. After another moment Hiro started to groan softly and slowly opened his eyes, squinting as the light streaming into the room hit him, which only made him groan more. 'Great he probably gave himself a concussion or something. Just great,' Tadashi thought to himself.

"Hiro," Tadashi started out at his regular voice but at his little brother's wince continued at a lower voice, "Look at me." Hiro did just that, but he didn't open his eyes. "Open your eyes," Tadashi prompted. Slowly, almost painfully, opened his eyes. One of his pupils were completely dilated while the other was really constricted. That pointed to four of the symptoms of a concussion: momentary unconsciousness, sensitivity to light, sensitivity to sound, and different sized pupils. Tadashi was considering getting Aunt Cass so they could take Hiro to the doctors and got up when Hiro finally spoke.

His words came out sort of sluggishly as he said, "My head hurts."

Tadashi had to chuckle at this and say, "Well, what do you expect when you repeatedly hit your head on your desk." Hiro looked at him and smiled this goofy little grin that made Tadashi smile as well. Hiro softly laid his head back on his desk, probably to block out the light of the room, and Tadashi started to walk towards the stairs to get Aunt thinking he started to yell to Aunt Cass down the stairs, like he usually did, then at Hiro's protest he went down the stairs into the cafe to talk to Aunt Cass.

When he stepped into the cafe he found it really full and his aunt talking with one of the regular customers. As he walked over to them Cass finished talking and went to walk back to cash register, where a customer was waiting to pay. He changed his direction and walked over to the register. As the customer was fishing in her purse for change Cass looked up and smiled at her eldest nephew.

"Hey Tadashi!" she said smiling, "What brings you down here? I thought you and Hiro were doing homework." Tadashi smiled shyly back at her as she finished up with that customer and started to deal with the next one in the line.

"Ya, we were." Aunt Cass looked up at how he said that and her eyebrows creased together at the look of worry on his face.

Aunt Cass asked hesitantly, "Are you ok? And you know I seriously can't help you with that homework, it's confusing to me."

Tadashi smiled at her and said, "Ya, I'm fine, and I don't need help with my homework."

He started to tell her about Hiro when she interrupted saying, "Is HIro ok then?" She even looked up from getting change to look him in the face.

He scowled slightly and said, "No," Aunt Cass froze at this and before she could ask he added, "I think he gave himself a concussion."

Aunt Cass sighed and finished with the last customer in line then asked, "How did he do that?"

Tadashi said, "He repeatedly hit his head on his desk, really hard."

Cass sighed exasperated again and called over one of her workers and said, "Ok, let's go get him to a doctor to make sure." Tadashi expected this. His aunt trusted him to know something like this, but it's better to make sure. They both walked back up the stairs to Tadashi and Hiro's room.

When they got back to the room they found Hiro with his head still on his desk. Aunt Cass slowly walked over to her nephew and placed her hand comfortingly on his back and whispered, "Hiro." He slowly lifted his head and looked at her.

"Let's take you to the doctor," she said softly and Hiro clumsily stood up and almost immediately swayed almost like he was dizzy. Tadashi mentally checked off another symptom as he grasped his little brother's arm, steadying him.

Hiro's face turned really pale as he looked at his guardian and brother and said so softly that it was hard to hear, "I don't feel good." 'Great. Just great.' Tadashi thought.

Cass said, "I know sweetie. Let's just get you into my truck ok." Hiro nodded and with Tadashi's help walked down the stairs and into the cafe. Once in the cafe they hurried outside as Aunt Cass instructed one of her employees. Once they got to the truck Tadashi helped Hiro up into the seat and got in behind him, letting his little brother lean against him. A minute later Cass got into the truck and started the engine. As they drove to the hospital, as they would have to go through the emergency room, Aunt Cass raved,in her normal voice, about how that it was stupid to do that, and he was banned from doing that again.

About halfway she was interrupted by Hiro groaning and saying, "Ok. Fine. But, can you stop yelling." Cass blushed at this remembering that even her normal voice must sound like a yell to him right now and Tadashi chuckled and softly ruffled Hiro's hair. As they pulled up to the hospital Tadashi thought, 'Well he won't do that again, at least,' and as they sat waiting he smiled at his silly little brother. He had been right about the concussion as the doctor told them and Hiro would have to rest and was restricted from school, electronics, and everything that required too much thinking. Tadashi smirked at this as Hiro would be so bored, but it was his fault after all.

No matter how many times Tadashi reminded Hiro of that incident he never stopped hitting his head on his desk, when he couldn't think or figure something out. Hiro knew if that ever happened again, his brother would be there to help him, no matter what. Until he wasn't there, anymore.

Hello again! Did you like it? I hope you did. I know it ended on a sort of sad note and I'm sorry for that, but I hope you liked the rest of it. And, I know I said I would get this up sooner, but I started basketball this week and didn't really have time to do anything. But, I have the next 10 days off, YAY! Anyways, I really hope you liked it and it was good. Tell me what you think. Also, I haven't actually done Algebra 2 yet, I'm in Geometry, but two of my friends are taking it and say it's really hard, so ya. I made it the math's fault. Lol.Read, Review, and Enjoy. :D

PS. For my readers from Watching the Movie- BH6 I should have the next chapter up later today or tommorow.
