Tadashi was pacing around the lab as Hiro worked on one of his projects that was still giving him trouble.
"Ah darn it. Stupid bot." Hiro grumbled as he pushed it aside. "It freaking hates me."
Baymax patted his head.
"There, there, I am sure it will work in time."
Hiro smiled a little. "Yeah…" He eyes wandered over to Tadashi who was going on his umpthenith loop around the room.
He's been deep in thought today… wonder what's eating at him.
"Hey, Tadashi?"
"Hm?" Tadashi stopped in his track looking over to his brother.
"What'cha thinking about?"
"Just… contemplating who the third person will be that I'll reveal myself to since number two has already been figured out."
"Remind me why Baymax doesn't count again?"
"He's an artificial being, he could see me before I could reveal myself so that's why."
"Got ya… So, have your mind set on anything?"
"Well… I was thinking… if he's still alive… Professor Callaghan was someone I was considering. I looked up to him a lot after all."
Hiro cringed at the name. "Oh… I-I see…"
Tadashi got a puzzled look. "What's with that look? Do you think it's not a good idea?"
Hiro sighed. He wasn't sure how to put it.
He needs to know…
"Tadashi… listen… About Professor Callaghan…"
"What? Is he dead?"
"No… he's alive… just…" Hiro clenched his hands into fists. "Tadashi, the reason you died… was because of him."
Tadashi looked at Hiro with questioning look before shaking his head chuckling.
"Very funny Hiro, nice try."
Hiro still had a serious look in his eyes… Tadashi found himself stumbling back.
"You're not joking… but… No… Why would he be the one to-"
"He wanted to steal my microbots so he used the fire as a way to cover his tracks… he didn't intend to kill you but… that's just how it happened… I'm sorry…"
Tadashi went quiet, thinking over everything.
"So… the reason I'm dead… was because he wanted something so badly he was willing to fake his own death?"
Hiro nodded slowly. "And nearly got me and the others killed all out of a revenge plot…"
Tadashi's hands clenched into fists as he lowered his head.
I looked up to him… He loved all of his students… and yet he was willing to kill some for getting in his way? Or even not care if he accidentally killed one?!
"Tadashi…?"
He turned away from Hiro.
"Thanks for telling me this little brother." His armor came on. "Excuse me… I think I have an old "friend" to visit."
Hiro's eyes went wide at how cold Tadashi's voice sounded. He knew very well what was probably on his brother's mind. He rushed over to his brother, grabbing his arm.
"Tadashi! Don't even think about it!"
"Why shouldn't I?!" Tadashi yelled, looking to his brother, rage in his eyes. "I would still be alive if it weren't for him! He nearly killed you and my friends! Why shouldn't I try something to make him pay for it!?"
Hiro growled a bit, some fear in his eyes mixed with rage of his own. "Do you seriously think you're not the only Hamada to ever want revenge!? I TRIED THAT ALREADY!"
The rage in Tadashi's eyes faded, being replaced by shock. "What…?"
Hiro lowered his gaze as the grip on his brother's arm loosened. "I took out Baymax's healthcare chip and ordered him to destroy Callaghan… I wanted to kill him for what he did to you Tadashi…"
Tadashi was silent as his armor faded off, turning back into his hat. "Hiro…"
The teen looked up pain in his eyes as he remembered it. "I was so angry… I didn't care… It was Honey Lemon who got the chip back in waking Baymax up again… Then on top of all that I abandoned them in Callaghan's hideout… I didn't stop being angry until…" Hiro's voice cracked as he choked on his words. "Until Baymax showed me the videos of you trying to get him to work…"
Guilt started to wash over Tadashi as everything set in. Seeking vengeance wouldn't fix anything… that was clear to him. Nothing could be done that would make anything that happened in the past better.
What have I done…?
He looked to his brother before bringing him into his arms, stroking his hair.
Hiro buried his face in Tadashi's chest quiet, he was shaking though. I didn't think he'd want to kill anyone… I didn't think he would actually want someone dead…
"Hiro… I… I'm sorry…" He buried his face in his hair a little. "I… I wasn't thinking…"
"It's… It's okay…." Hiro murmured hugging his brother tighter. "Just… Leave him alone… He already got his sentencing…"
"I will… besides… I wouldn't be living up to the name I hold…" Tadashi sat down with Hiro in a chair. "Remembereds take an oath to only protect and to never kill out of blood lust or pure rage… I almost just broke that oath…"
Hiro curled up to him a little. "Good thing you didn't then… I don't wanna lose you over something as petty as revenge…"
"And you won't…." Tadashi nuzzled him a little. "Just lost it for a moment… I don't think I'd even be able to do it…"
Hiro nuzzled back. "You're a good person Tadashi… You're too nice to do something like that… But you do have full permission to haunt him if you want… Scratch names on the walls and stuff."
Tadashi couldn't help but smirk. "You little devil."
Hiro smirked back. "Careful might sprout horns if you look close enough."
Tadashi laughed, ruffling his hair.
"So that would make you… a superhero, a nerd, a part timer and a devil… Talk about a full schedule."
"Well I am the devil." Hiro laughed.
Tadashi sighed, hugging his brother close.
"Thanks for slapping sense back into me… Though looks like I'll be taking time again to think about who the third person will be…"
"Take time…. And anytime bro… You pulled me out of crazy stuff too…" Hiro nuzzled a little. "Just think it over clearly."
"I will…"
"Good... Now… I do need some help from my super smart awesome Nii-san…."
Tadashi chuckled. "At your service."
Hiro gave the puppy eyes as he pointed to his work table. "Help? I'm gonna go nuts if I can't get this thing working…"
"Alright, alright, no need for the eyes." Tadashi got up, looking the robot over. "Hm… I'll need to look over everything to see what's wrong but I'm sure we can get it working."
Hiro sighed in relief. "Thank goodness... I've been working on it since I was fifteen… It's been driving me nuts."
"We'll work on it together then."
"Awesome!"
The two got to work, pretty much forgetting everything that had happened. It nagged Tadashi for another moment but then he shook it off.
Sure… he took my life… but killing him wouldn't fix it… and it would only make it worse… I'd leave my brother again.
Hiro had a smile on his face as he watched his brother work. Tadashi stole a glance, smiling to himself as he focused on his task.
And the last thing I want is for him to be sad again… So I'm leaving it behind me… Besides… I can do a lot more now than I could as a human… so I guess I should say thanks Professor Callaghan… You allowed me to get powers… and I can protect my brother.
