Oh my gosh, I'm SO sorry for taking so long to update. My school had a weekend production that I was involved in and I couldn't find the time to write, in my opinion, a decent enough final chapter. Yup, this is the last chapter in Home Coming, I only ever intended for this to be a snapshot of when Tadashi first come home, and don't want to risk continuing and drifting off topic. However, I am thinking of a possible sequel which I might start a bit later on, depending if I have the time and what you guys think of it.

But for now, please enjoy this!

"Hiro, I want- no, I need- to see Callaghan."

"You... what?"

"It's important Hiro. I mean from what Go Go said that day, he was the reason behind everything that happened right?"

"Mmm," Hiro understood where his brother was coming from, he had thought about going to see Callaghan a few times as well but was too afraid he'd end up trying to hurt the man if he triggered something too sensitive, so he had held himself back. But now that the worst event in his life was miraculously reversed... "I know what you mean bro, but I think we're too tired to talk this out rationally now. We'll see how tomorrow?"

"Mmmkay," Tadashi could feel the insurmountable need for sleep consume him, "Good night Hiro."

"'Night Tadashi."

Hiro stayed up long after his brother's sleeping had slowed to a regular rhythm. How had he even slept the past eight months without that calming sound he had otherwise never been without since his birth? Tadashi wanting to see Callaghan was only justified, but was this too soon? He had barely returned home, he didn't even know the full story apart from Go Go's abridged hospital version. And what would the others say? Would Aunt Cass just let him run off to meet the man who almost killed both her nephews? What would the rest of the team say? The younger boy sighed and slumped onto his pillow. Maybe things will be easier to figure out in the morning.

- The Next Morning -

Tadashi woke up to squeaking vinyl and his little brother's sleepy grumblings, as Baymax tried his hardest to wake up a Hiro who clearly had no intention of getting out of bed anytime soon. He couldn't help the small laugh that escaped him, which caused Baymax to turn to him. "Good morning Tadashi, would you like me to wake you up as well?"

"No it's fine Baymax," he smiled at his robot. "Just waking Hiro up this early alone is almost too much to ask of you."

"But you made to help people, I am just doing my job."

Hiro perked up at the sound of his brother's voice, finally getting out of bed, and Tadashi would swear that he saw relief flash over Baymax's hyperspectral camera eyes. "Tadashi!" he exclaimed, crossing over to the other side of the room, finally without the sharp pang he had felt every time he did that over the past few months. "You need to come to school with me! Everyone will be so happy to see you!"

"Well well, look who can't wait to go to school this morning. What would the Hiro of last year say to this," Tadashi tsked.

"No, I can't wait to take you to school. Me on the other hand, I have so many, far more fun, things to do that sit for hours while random old people tell me things I've known since I was like 10."

"Sure okay, but tiiiny little snag in your plan kiddo- I can't really walk that well yet, remember?"

"Well yeah, but you also created a robotic nurse pretty much specifically for such a purpose, remember?" Hiro mocked him, while shooting a pointed glance at said robot.

Baymax blinked as he scanned the older brother. "Tadashi does seem stable enough for a day in the SFIT Robotics Lab, although perhaps not so much for the walk to our destination. But I take it that Hiro wants me to help you with your transportation?"

"Yup! Thanks Baymax, you're awesome!" Hiro patted the robot's poofy tummy as he ran into the bathroom, before Tadashi remembered just how messy he made the place and insisted on going first.

Later, as the two brothers walked up the steps to the 'nerd lab' (well Hiro walked, Tadashi was being carried by Baymax), the former tried to bring up the topic of visiting Callaghan as casually as possible. "So erm bro, what we were talking about last night..."

"I know you and the others probably won't approve, but I really want to see him Hiro. I think the least I deserve from all of this is some reasoning and closure."

"No, I do get it Dashi. I almost went up a few times myself, but the way he just... didn't care about you, I knew I couldn't trust myself to not try and kill him or something."

"Kill who?" Go Go walked up to the trio, the last bits of what Hiro had said came within her hearing.

The brothers looked at each other awkwardly. "Erm-"

"Tadashi wants to see Callaghan," Baymax blabbered.

"What?"

"Dammit Baymax," Hiro hissed at the robot before turning to his brother. "Now that you're here, you better get to work programming your robot to not be so stupid."

"But Hiro, that was what you were-"

Baymax was interrupted by Go Go's shrill "YOU WANT TO SEE CALLAGHAN?" that immediately brought the other three members of the team running over to join them.

"What?"

"Oh Tadashi…"

"Careful dude."

Frustrated by the unanimous opposition to his brother's wishes, especially since he largely supported him, Hiro grabbed Baymax (and therefore Tadashi) and stormed into his private lab, if he could even call it his private lab anymore now that Tadashi was back, the others following closely behind.

"You guys don't understand," he defended his older brother, "at least we had the closure of defeating and arresting Callaghan. Dashi has only seen him win by setting the fire and almost killing him."

"Yeah but-"

"I just... I still can't come to grips with that fact that Callaghan could do something this bad-"

"Well he did, so just accept it."

"But I can't. Not yet. I know you don't get it, but I need to see him in jail, to see him as the bad guy. Because so far my memories, my only actual memories of Callaghan, are the good ones."

Fred and Honey were the first to accept it, nodding sympathetically at Tadashi. "Just be careful okay? He's really not the Callaghan we thought we knew. He'll try to get under your skin and do God knows what else."

"I know what could happen, and I'm not saying I want to go, say, tomorrow. But soon, within this month hopefully, I need to get some form of closure."

"I guess if you take some time to readjust and all first then it's okaaay," Wasabi respected his friend's decision and Go Go was left as the only strong opposition, still not wanting her friend to have to face the man who so blatantly betrayed all of them in so many ways.

"Tadashi..."

"I can handle it Go Go. I'll be careful, just trust me."

"Will meeting Callaghan improve your emotional state?" Baymax tilted his head, almost mirroring what he had asked Hiro after that first fight.

"Yes," Wait but as important as it is to see him will it really make me feel happy? "No. I... I don't know. But I just really need to see him" Hiro couldn't help raising an eyebrow at his brother and even Baymax blinked at the déjà vu moment.

Go Go sighed, knowing that she wouldn't win over the rest of them and frankly she did agree with Tadashi deep down, though her overprotective nature over her friends prevented her from admitting it openly. "Okay then, if that's what will make you feel better."

Tadashi smiled gratefully at her, before his gaze landed beyond the team and on to what used to be his perfectly organized lab. The messiest it had been was during the testing phases of Baymax's development when he had struggled to fix each of the very different 83 problems the beta Baymax had thrown at him. But now... now Hiro's side of their bedroom seemed like it had been organized by Wasabi in comparison to the lab.

Realizing that his brother was giving the lab a careful (and horrified) look-over, Hiro sheepishly tried to hide behind Baymax. Too bad he forgot that the robot's allegiance was more to his older brother than to he himself. "Hiro, are you trying to hide from Tadashi?"

"And for good reason," Tadashi glared at his younger brother, "for very good reason."

"Look, I try, okay?'

"You try?"

"Finally someone understands how I feel about this post-apocalyptic scene!" Wasabi burst out in exasperation. "At least now do you understand why I don't want to come into this lab?" He turned to the younger Hamada who just looked around and shrugged in response.

"I mean, if you're not happy with the way it is you can clean it up,"

"Wow, your brother is just one day out of the hospital and you're already asking him to do the hard work?"

"Or he can suck it up, and when he comes back to school then I'll maybe think about helping him organise it the way he wants," Hiro shot his brother a sickly sweet smile, who rolled his eyes in return.

"Information downloaded," Baymax's randomly stated amidst the banter.

Hiro walked up to the robot, tapping his stomach to instruct him to show whatever that information was. "Er… what are you doing?"

Baymax obliged, displaying various contact numbers and addresses on his screen. "I downloaded the information on prisoner visitation regulations. Would you like me to contact the prison where Callaghan is for you?"

"Woah no no no hold up!" The team rushed up before Baymax could place the call. "We haven't even gotten the approval from Aunt Cass yet."

...

"Oh sweetie, if you feel it's something you need to do to make you better, then go for it. Just take care, okay?"

Tadashi nodded gratefully. Well that went over much easier than expected. "Hiro and the gang said they'll come up with me to make sure nothing happens."

Aunt Cass sighed at the mention of the team activating their superhero identities again, but then the last time they had done so it had brought Tadashi home so… "Okay, I guess I have to learn to trust you guys to take care of yourselves by now anyway.

"Thank you for understanding Aunt Cass." Tadashi smiled. "Could you please sign these forms giving us approval to go up there?"

-Two weeks later-

"Callaghan! You got a visitor coming up soon. Clean up and get ready for transportation in 5," the prison guard tossed the clipboard with the visitor information to the ex-villain, turning back as he heard the sound of it clattering to the floor. "What Callaghan, did you see a ghost?"

Callaghan froze. No way. There was no way. All the reports about the SFIT fire said that his former student had died. His kid brother had said he had died, right before setting an almost deadly Baymax on him. There was no way anyone could have survived that explosion, not without the protection of those microbots.

He turned to face the guard, his eyes wide and face pale, "… yes."

The guard shrugged coldly, "I've never seen a murderer who wasn't afraid of ghosts. Maybe you should've thought about that before you went around terrorising the entire city."

No but this… this isn't some figment of my imagination. This is… this is… Too late, the guard had already left to get the handcuffs and ankle shackled required to transport a prisoner considered as dangerous as Callaghan even within the prison walls. This cannot be true. It's probably that brother of his and his friends, there idea of a stupid trick. Callaghan felt the anger build up inside him as the guards bound him and led him down the hallways to the private meeting room. Stupid punks ruined my life, and now they pull this kind of a trick? What, do they possibly think it is funny?

The group landed a short distance away from the prison, they had flown in on Fred's chopper rather than Baymax because it wasn't safe for Tadashi to fly in the open without a suit, much to Wasabi's relief. The Big Hero 6 members scrambled into their gear as Tadashi went ahead to sign himself in. The team knew they wouldn't be allowed into the prison in their armour, but they didn't particularly want to go see Callaghan in plain clothes with an impossibly cute Baymax in tow, so they had opted to stand outside the meeting from window, ever ready to blast their way in if they ever saw the slightest sign of something going wrong.

"Dashi!" Hiro called out to his older brother just before the latter was led into the building, running over to him and hugging him tightly, "Be careful in there okay? If anything is about to happen-"

"I'll call out to you guys," Tadashi repeated the plan they had run through innumerable times in the past weeks. "Hiro, hey buddy, just trust me okay? I can handle this."

Hiro nodded, giving his brother one last hug before turning back to the team, to keep a sharp eye on the entire exchange from the outside. He had just updated Baymax's sensors to make the robot more easily able to pick up and specific sounds, especially Tadashi's voice, over a longer distance than he had previously been able to.

Tadashi took a deep breath as he stood outside the meeting room, steeling himself to see Callaghan. This isn't the man you thought you knew. This man had no qualms doing anything, hurting anyone to get his way. The man who had been living a lie for years. A hint of fear touched his heart as the guard reached for the door but he brushed it off quickly. Callaghan was clearly cuffed and bound and after all, Hiro and the rest were just outside with more than enough power to stop any wrong.

He stepped into the room, making eye contact with the man he had once looked up to almost as a father figure. "Hello Callaghan."

Callaghan tried to look away, anywhere except the young man in front of him, but outside of the sole window to the interview room stood a massive red figure, flanked by four other smaller ones all decked out in full gear, all of whom he knew too well.

"Talk."

"What?"

"I said talk."

Callaghan glanced from the window back to the young man in front of him. "Alright, what do they want?"

"I'm sorry?"

"How much did those punks pay you to come talk to me?"

Outside, the team, listening to the conversation through Baymax's speakers, could barely hold in the urge to burst through and almost kill that bastard. Thankfully, Tadashi was able to hold himself together better than the others.

"You think I'm acting? You think this is a joke?"

"No… No you died. The fire… the explosion. I saw you die."

"Well too bad for you I didn't. Now talk."

"What, your stupid brother and his gang didn't tell you enough that you have to come to me?"

"Oh, they told me plenty. I just want you to hear it from you."

"I have nothing to say."

"What could have possibly possessed you to terrorise the entire city and-"

"KREI TOOK MY DAUGHTER FROM ME. MY DAUGHTER. And you expect me to just sit back and relax?"

"No, i just didn't expect you to steal my brother's invention and almost ruin the entire city."

"Then what else-"

"You could've gone to the authoriti-"

"Krei was supported by the most secretive sects of the military. Do you really think anyone would have listened to me?"

Tadashi sighed. "You were a professor in one of the best robotics departments in the country. You could've asked us to help out. We could have found a way in and-"

"You're just kids. What could you have done?"

"Well they," Tadashi gestured out the window to the waiting Big Hero 6, "managed to defeat you. It's pretty clear that we could have helped if you had let us."

Callaghan sat back on his chair, sizing up the young man- was it really Tadashi?- in front of him. "As if any of you would have bothered to get your lazy asses out of the lab if I hadn't terrorised the city. If I hadn't killed Tadashi." He sneered at the group through the window.

Outside, Honey placed a gentle, calming hand on Hiro's shoulder but he shrugged it off, unbothered. If that was what Callaghan wanted to believe, Hiro was more than fine letting him believe it. As long as Dashi gets the closure he needs.

"But you didn't, I'm still here."

"So you just came here to gloat?"

"No, I came here to hear what you had to say about this whole thing-"

"I have nothing to say. Ask that genius brother of yours."

"I wanted to see if you had changed in any way, if the man I thought I knew was in there in the slightest."

"The only place 'that man' existed was in your dreams."

"Clearly." Tadashi looked Callaghan squarely in his eyes before walking up to the door and asking the guard to let him out. "Oh and by the way," he turned to face Callaghan one last time, "test 46 was when Baymax failed to inflate because I forgot to reprogram that action into him after wiping his hard disk." Tell him something only the two of you would know, so he'll know it's the real you, he remembered Hiro's advice from the day before. Tadashi heard a metallic clang from inside the room, presumably Callaghan slamming his cuffed hands on the table, but Tadashi didn't give his ex-professor the time of day to see what had really happened.

Tired, disappointed and above all frustrated, the older Hamada brother headed straight for the waiting chopper, barely giving the team time to catch up with him. "Dashi?" he heard his younger brother call out to him nervously as he too clambered onto the helicopter.

"Tadashi?"

"Dude?"

The rest of the team filled in after stripping off their gear, but Tadashi tuned them out the best he could, leaning his head on the window and glancing out at expanse of green that stretched on ahead of him. There was never the Callaghan you knew, only a coldly calculating psychopath who was waiting for the best opportunity to let it show.

"Dashi," Hiro sat beside his older brother, leaning on his shoulder, "look, I know it's hard to-"

"Doesn't matter."

Hiro looked helplessly at his friends, before a new idea sprung to mind. "Hey Dashi? You wanna see the superhero us in action?"

"Wha- what?"

"Oh yeah!" Fred could barely contain his excitement at the chance to use his powers again. "Say yes man, this is gonna be so cool!"

The rest of the team started buzzing with excitement too, even Baymax who had been trying his hardest to come up with cures for Tadashi's bad mood. "Such excitement is sure to improve your emotional state."

Looking up at the hopeful faces of his brother and friends, Tadashi couldn't help but agree. After all, it's not their fault i over-idolised a man I barely knew.

Heathcliff had barely landed the chopper as the Big Hero 6 team jumped out, ever ready to show off their skills to Tadashi. Hiro especially was desperate to get his brother's approval to continue with his flying Baymax, which was ironic giving how little he used to care about what Tadashi said when he went bot fighting.

"Dude catch!" Fred called out to his butler (now dummy villain) as he tossed him one of the many Kabuki masks the team had made during their initial testings. "Let's go do this thing!"

From there on, it was as they had practiced so many times in the past, with Honey, Go Go, Wasabi and Fred taking their turns to 'capture' Heathcliff using their individual abilities as the butler kept his cool, reading a book through his mask.

Tadashi watched them go through their actions, becoming genuinely interested in what they were doing, though he would never let that on to his younger brother. Finally however, it was said younger brother's turn to show off what he could do- though it was more like what Baymax could do. "Okay okay okay, are you ready Dashi?" he bounced around in front of his brother as Baymax stood by in the front lawn, his bright red armour glinting in the setting sun. "Baymax, show him the fist!"

"I assume you mean my rocket fist, and not my fist bump?"

"Yeah buddy," Hiro laughed with the rest, "show him your rocket fist."

Seconds later, a small blast ripped through yet another statue and another piece of the garden wall before Baymax's right armour fist came back to him. Tadashi sat up at that- if he hadn't been engaged during the others' demonstrations, his friendly healthcare bot punching a sizeable hole through a solid stone wall certainly perked him up.

"Alright buddy," Hiro ran past him, climbing up Bayamx's armour and clicking his palms and knees onto the matching slots on his robot. "Wings. Thrusters." The robot dutifully followed the orders given to him. "Now fly."

"No Hiro wait!" Tadashi kept up, but was too late as Baymax and Hiro launched into the evening sky, flying behind the mansion for a while to get their balance.

"Chill Tadashi," Go Go kicked her feet up on the deck chair beside him. "This isn't their first flight, you know."

"Yeah man, have some faith in the kid."

"But-" Tadashi was cutoff as said kid and robot reappeared in front of them, performing various loops, straight up thrusts and- almost giving Tadashi a heart attack- an unpowered drop off a nearby skyscraper.

The duo finally landed on the lawn again, as Tadashi ran up to inspect Hiro and Baymax, only to find his brother's face flushed with the thrill of the flight, and his robot blinking at him good-naturedly. "Hello Tadashi, did you like seeing us fly?"

"I-"

"If you would make a suit for yourself, I can take you on a flight too." Hiro glanced from the robot to his brother, nodding enthusiastically, but Tadashi rolled his eyes at both of them, heading back to the where the rest of the team was sitting.

A few minutes later, over the snacks and drinks Heathcliff had brought out to them, Tadashi waited for a lull in the conversation before speaking up. "So guys, grey/silver doesn't seem too bad for a suit, does it?"

And there it it. I think I screwed up the deep emotional parts, and I'm so so sorry for that, especially since they were the keystone of the chapter. I hope this wasn't too much of a disappointment in any case…

Thank you to everyone who reviewed/favourited/followed, I really didn't think I'd get anywhere near this level of response to my first BH6 fic! You amazing people really inspired me to continue writing, so I posted a small teaser to the sequel I'm thinking on in the next chapter, please tell me if you think I should continue that thought, change it, or just stop writing huehuehue/

Thank all of you once again for sticking with me through this past week or so, and I really really love every single one of you!
