He was a wreck. An emotional wreck. It had started off just fine, they were up at Piston Peak National Park, himself, his aunt his brother and his brother's friends. It was cold as heck but they were having a good time regardless.

Hiro had been having the time of his young life, spending most of that trip snowboarding down the hills, or chasing after his older brother and playing a few tricks on him…

But then the fire happened.

Tadashi had done his best and when it came to protecting Hiro or making it out himself, he chose his little brother.

That was a fatal choice.

And now Hiro felt like he was alone. He was shut up inside his room, not wanting to talk to anyone, not wanting to eat anything. He tried for his Aunt Cass's sake, he really tried but he only ate enough to keep himself awake.

Tadashi's death was Hiro's own personal nightmare.

He sighed as he looked at Megabot who sat innocently on his bookshelf. Even the bot fighting Tadashi always had to bail him out of when things went awry hadn't brought up his mood.

Hiro narrowed his eyes and picked up the robot throwing it across the room with an enraged cry. "IT'S NOT EVEN WORTH IT!"

The robot clattered as it fell apart, the magnetics pulling it back together. Hiro looked at it with a glare before he sighed, sitting on his bed. He looked over to Tadashi's side of the room.

Every day he kept expecting to walk around the screen that separated their beds and see his big brother there. He sometimes dreamt about it.

"You idiot! Stop scaring me!" He would say and in the dream whack Tadashi with the hat Hiro had given him when he had graduated high school. Tadashi would laugh and call him a knucklehead for falling for his trick and it would be alright.

Then Hiro would wake up and notice how quiet it was without Tadashi around.

Hiro went over to Tadashi's side of the room. He felt a pang of grief as he looked it over, it was exactly how Tadashi had left it. His old favorite book still having a bookmark where Tadashi had left it when he had been hurrying to pack up for the trip.

How Hiro wished they had never gone. "Big brother…" He called out quietly. "I need you…. It… My heart…" He choked up before sobbing as he fell on Tadashi's bed. "It hurts! It hurts so much…!"

Unbeknownst to Hiro something of his brother's activated. "On a scale of one to ten how would you rate your pain?"

The boy looked over eyes going wide at what was before him. A tall… puffy robot. One he recognized as he relaxed a bit.

"Baymax…?"

"Correct. Your personal healthcare companion."

Can't believe it's still active… I mean Tadashi hasn't brought him out since he finished him… "My personal healthcare companion?"

The robot nodded. "Tadashi designed me to take care of the Hamada family… More specifically. To take care of you Hiro."

His eyes went a little wide before he glanced over to a picture on the wall. Hiro had been thirteen in it, Tadashi was messing up his hair as Hiro tried to get away from the camera. You knew something might happen one day didn't you…?

"Thanks Baymax... But I don't think you can fix this one."

Baymax looked at the boy scanning him.

"You are experiencing mood swings… Anger… Sorrow… Associated with depression and grief."

"I'm not depressed." Hiro growled a little. "I…" He went quiet. "... Alright… I miss Tadashi…"

"There, there." Baymax patted the boy's head, noting the way Hiro relaxed slightly. "It is alright to cry."

"Yeah… Long as no one sees… I can't stress Aunt Cass out more…"

"But you are stressed as well."

"I just…" Hiro sighed. "I guess you could say my heart's broken... "

"Scanners indicate that your heart is in perfect working condition."

"Expression buddy… It means I'm… Okay I'll say it! I'm depressed… I'm miserable… I… My brother was my best friend…" Hiro ran a hand through his hair, getting up as he paced around the room a bit. "I know people keep saying Tadashi isn't gone long as we remember him but I don't WANT to just remember him. I want him here. With me!"

"Hiro… Would Tadashi be happy seeing you like this?"

"... No." He looked Baymax over raising an eyebrow. "But… I don't think he wanted a robot to replace him."

"I do not intend to be Tadashi's replacement. I intend to look after you as he has requested." Baymax picked the boy up, as he squirmed.

"H-Hey!"

"Close contact and compassion can help with grief." Baymax stated holding the boy close. Hiro went quiet, relaxing. He couldn't help it… It was nice to just have someone willing to listen… Not telling him the same things over and over.

Hiro closed his eyes hugging the robot as well, curling up.

"You will be alright Hiro… I will look after you…"

"Thanks Baymax… Don't forget Aunt Cass either… She's important too…"

"But you are first priority." Baymax stroked Hiro's hair, recalling seeing Tadashi do the same a few times during the late hours of finishing up programming and Hiro had finally passed out from exhaustion.

Hiro nuzzled his hand a little yawning a bit. "No fair…" He mumbled. "That trick always works…"

Baymax rocked him a bit as Hiro started to drift. He laid him on his bed bringing his blanket up over him. Hiro mumbled something. "Are you satisfied with your care?"

"Yeah…. Satisfied with my care…" Hiro smiled before curling up relaxing for the first time in awhile.

Well… Least I still have one piece of Tadashi left…

Baymax will have my back…
