A thunderstorm has struck San Fransokyo and it just so happens Hiro has a slight phobia of them. Cue Tadashi attempting to comfort his brother.

Crash

Bang

Hiro startled when another roar of thunder echoed through the room, a flash briefly illuminating it. His heart pounded wildly against his chest and he groaned into his mattress. Though his brain knew it was illogical to be afraid or the storm, that he was perfectly safe in his bed, it looked like his body hadn't got the memo.

In an effort to block the noise of the thunder and pounding rain, Hiro put his pillow over his face but the next crash that came proved it was ineffective. He groaned again, just wanting the storm to be over already so he could get some damn sleep; though, if the reports were to be correct (which was getting to be a bit more often), then the storm was set to last all night.

Maybe he should just give up on sleep and try and work. Then again, manufacturing robotics was not the best thing to do with jittery hands and an unfocused mind, especially since he'd only had a few hours' sleep the night before. Perhaps if he just stuck to designs…

"Hey Hiro." Tadashi's voice was quiet and Hiro just managed to hear him. He was surprised Tadashi was awake. Usually, his brother managed to sleep through anything, which was good when Hiro stayed up too late at his desk. Hiro was pretty sure Tadashi wouldn't like to know how often that happened.

"Yeah Tadashi?"

"…How you doing?"

Hiro only just managed to hold in a moan of despair. Tadashi had his 'concerned big brother' voice on and that was the last thing Hiro needed. It was fine to be afraid of storms when you were five but now? It was just embarrassing, especially being called up on it.

"Fine Tadashi, go back to sleep." Hiro put the pillow on his face again. Maybe that would stop Tadashi going for a 'brotherly bonding moment'.

"Eh, I'm not that tired." Just as he said the words, Hiro heard his brother let out a huge yawn that had him rolling his eyes. Sure, he was totally not tired.

"I'm fine," he repeated, though the statement became particularly untrue when another boom of thunder rang and Hiro nearly fell out of the bed with how much he jumped. His breath came out in quick gasps and he was thankful the pillow was still there to muffle them. Man, he hated storms.

"You know…my bed always has some space if you…"

"No!" Hiro cut Tadashi off before he could finish. There was no way he was sleeping in his brother's bed. He was fourteen years old! Was Tadashi so old that he didn't understand how not cool that was?

"Hey, I was just offering; I know you don't like storms…"

Didn't like was maybe an understatement but Hiro wasn't about to correct him. Instead, he emerged from under his pillow only to try to delve as deep as possible under his covers, attempting to ignore the flashes that travelled through the covers and hit shut eyelids. Maybe if he stopped responding then Tadashi would just think he'd gone to sleep….

Hiro felt a dip in the bed and his eyes snapped open.

"Hey! Get off!" His leg struck out and managed to connect with the small of Tadashi's back, causing his brother to yelp in pain.

"Look, you can't sleep and I can't sleep if I know you're scared so just let me in and stop being a baby!" Tadashi exclaimed, remaining on the bed despite Hiro's constant stream of kicks.

"Then stop treating me like one!" Hiro retorted, now using his whole body to try and shove Tadashi off but to no avail.

"There's nothing wrong with being comforted. I'm your big brother, it's part of my duty!"

"I'm fine," Hiro repeated for the umpteenth time though his resolve was fading. Even with Tadashi only sitting on his bed, Hiro could feel the tension and fear slowly bleed from his body and he silently cursed his traitorous body. Tadashi must have noticed because he inched closer, getting bolder when Hiro no longer fought him.

"Move over," his brother urged softly and with a huff, Hiro did, making sure he was facing away from Tadashi. He'd just reached the edge of the bed when Tadashi slid in, the fit being a bit tighter than Hiro remembered it being. Then again, the last time they had shared a bed had been over two years ago.

Thunder boomed but this time the fear only lasted seconds as immediately as it sounded, Tadashi wrapped an arm around Hiro in a protective hold. Hiro breathed out a relaxed sigh.

"Just so you know," Hiro said sleepily, "I'm only doing this so you can sleep."

Tadashi let out a soft laugh, his breath tickling the tips of Hiro's hair. "Of course you are, now get some sleep Hiro."

And Hiro did.

So I've been needing to write some Big Hero 6 stuff since seeing the movie mostly just so I can pretend the whole Tadashi dying (seriously Disney, why?) didn't happen. I know it's slightly random that the one-shots all happen at night but that every idea that comes to me seems to be set then.
