A/N: Here it is! The big reunion. Hope you all enjoy.

"Apartment 317…" Hiro whispered to himself, walking down the hall. He hoped that this was the right place, and that Tadashi was inside. For one thing, he just wanted this over with, and for another, he didn't want to walk into some random person's apartment.

Taking a deep break, Hiro first knocked on the door. After a few moments, he got his tools out, ready to break in.

Hiro had recently created a small tool that could unlock a basic lock in ten seconds. It was useful in many of their adventures, especially this one.

When the door flew open, Hiro looked around him to make sure no one had seen, before tip toeing into the dark room.

The apartment was small. It only had a living room, a bathroom, a kitchen, and what he guessed was a bedroom. Hiro walked up to it, slowly inching open the door.

There was someone sleeping in the bed. Hiro's heart raced as he walked up to the figure.

Nothing could prepare him for the moment that would come when he saw him.

It was Tadashi, plain and simple. Hiro couldn't have any doubt. He stared at his brother's peaceful face, calm in his sleep, and he had to take a step back.

Tadashi was here, in front of him. This was his chance to talk to Tadashi, to get him back.

But all Hiro wanted to do was run. He was actually turning to face the door, when he stopped. He had to do this. If Hiro left now, he would regret never knowing what really happened.

And did he want to know. Instead of turning back, he shut his eyes tightly. Hiro felt the swell in his throat, and the wetness in his eyes. He was about to lose it.

There had been so few nights that he had done this recently. But, Hiro broke down. He made sure to be silent as he sunk to the floor of the Tadashi's apartment.

Crying was something that Baymax was always there for. But this time Hiro had made him stay home, and Hiro regretted it. He regretted not having his closest friend there, because he didn't know how to handle this on his own.

"Hey!" Tadashi suddenly said, apparently awake. Hiro turned around to see flames heading towards his face. He yelped and rolled out of the way.

"Tadashi!" Hiro said, his heart pumping as he backed into the wall. "It's me, Hiro!"

The angry look on Tadashi's face melted away, and his hand dropped to his side. His eyes were wide in the dark room, and Hiro felt down the wall to turn the lights on.

"You weren't supposed to find me." Tadashi said, as soon as the lights came on.

"Two years…" Hiro said. "Two years, and that's what you say to me?!"

"Hiro, how did you find me!?"

"A tracker!" Hiro yelled. "You used to put them on me, so when I chased you in the alley that day, I put one on you. I knew I wasn't crazy; I knew it!"

"You need to leave!"

"No!" Hiro said, and gathered the guts to walk forward. "You left me for two years, Tadashi. You owe me an explanation!"

"Hiro, I'm dangerous!"

"You're my brother!" Hiro reminded him. "I don't care what you are; we're not supposed to leave each other! This isn't that hard Tadashi!"

"Look at me, Hiro!" Tadashi yelled, and he walked closer too. He lifted his hand, and flames shot out of it. "I'm fire. I burn things. I have killed people! Get out of here now!"

"And I'm saying no!" Hiro said. "I don't care that you're some sort of weirdo who can create fire! Have you met Fred?"

Tadashi stepped back, but Hiro continued.

"We are family, Tadashi! Did you forget that?" Hiro said. "When you left?"

"Hiro… I-"

"Whatever." Hiro said, taking a deep breath. "Wasabi told me to come here and kick your ass, so I did. I got my closure. Come after me if you want."

Hiro wiped at his face, and turned around. He was halfway out of the apartment when his phone rang. Hiro stopped, and answered it.

"Hello?" He said, not caring out he sounded.

"Hiro," The soothing voice of Baymax said. "I was just calling to see if you are alright."

Hiro felt his face form a small smile, despite the situation. "Yeah. I'm okay, buddy. Thanks for calling."

"Did you find your brother?"

"Yeah." Hiro said, glancing back at his brother, who stood in his room. "He wasn't happy to see me."

"Would you like me to pick you up?" Baymax asked.

"No." Hiro said. "I can make it home myself."

"Please let me know if you change your mind." Baymax said.

"I will, Baymax. Bye." Hiro said, hanging up the phone.

"B-baymax?" Tadashi asked, walking to the doorframe. "As in the robot I built?"

"Yeah." Hiro said, sighing. "I've been doing some work with him. I'm making new prototypes that are set to be in hospitals next year."

"That's great." Tadashi said. "I'm sure Baymax will be happy there."

"No, he's not going." Hiro said. "Aunt Cass and I … well, we're a little attached to say the least. We're keeping him. Besides, he wouldn't do well in a hospital anyways."

"Why?" Tadashi asked, interested. "Does he have a glitch?"

"I don't think you can call it that." Hiro said, smiling at the memory of his best friend. "He's more like his own person. He loves helping people, but he's just Baymax, you know? He isn't a robot." Hiro paused. "Whatever, it's weird. I'll leave you to your own now. Bye, Tadashi."

Hiro began walking towards the door.

"Hiro, wait." Tadashi said. Hiro turned around, daring himself to be hopeful.

"What?"

"You do deserve an explanation. I see that now." Tadashi said, touching the wall that he had thrown flames at. They disappeared into thin air. "You need to know what happened in that fire."

"So, you can make and destroy fire." Hiro said, watching as Tadashi lit and un-lit a candle.

"Yeah." Tadashi said. "After two years, I have a pretty good lid on things, but I still lose control."

"Was it some sort of … chemical?" Hiro asked.

"Yeah." Tadashi said. "When the fire exploded, there I was next to this exhibit someone had on a chemical that could make the lifespan of a person last longer. That chemical got all over me, and I woke up in the burning building."

"Well, why didn't you try to find us?" Hiro asked.

"I did at first." Tadashi said. "When I got out, I tried to find a firemen, or something."

"They let the building burn itself out, because of all of the chemicals in there." Hiro said. "It was too dangerous for firemen."

"Yeah, so I went to a small store to maybe try and make a call, but there was this woman getting harassed by some guys. I went in to stop them, and they took a shot at me, and the suddenly, the whole building was on fire." Tadashi said, and he looked as if he struggled to say what was next. "I… No one made it out."

Hiro gulped, trying to find words that would make it better. Suddenly, he remembered Baymax always saying that a good way to make people feel better was with compassion.

"It's isn't your fault."

"Hiro, I still sometimes get like that." Tadashi said. "I still sometimes lose control. I can't… I can't be around you knowing that."

"Why? Because I can't handle myself?" Hiro said. "You don't know all that's happened since you've been gone. I can deal with this. We can make it better."

"Hiro, I'm not taking the chance. I'm sorry." Tadashi said. "Please, if you haven't already, don't tell Aunt Cass I'm alive. I can't take her being upset about this."

Hiro stared at Tadashi. He was about to get angry again when he heard the door open. Instantly, Tadashi's hand was on fire, but Hiro grabbed his shoulder.

"Relax! It's just Baymax!" Hiro said. Tadashi jumped away from him, hitting the wall as he did so.

"Hiro?" Baymax asked, walking fully into view. He had come without his armor on, which was somewhat good. He didn't think Tadashi could handle the news that Hiro was a superhero right at that moment.

"Hey, Baymax."

"You told me you were coming home, and when you did not, I began to worry."

"Sorry, buddy." Hiro said. "Tadashi and I were talking."

"Is this talking helping your emotional state?"

"Uh, kind of." Hiro said. "I was about to leave anyways."

"Hello, Tadashi." Baymax said, looking at the older Hamada. "It is good to see you are healthy."

"Yeah, good to see you, Baymax. How are you?"

"I am well. I have a full charge, and my sensors are all working perfectly." Baymax said.

Hiro couldn't help but chuckle. "You're getting better at that, bud. But you still need some work. Batteries and sensors kind of sound weird to us people."

"Oh." Baymax said. "When I get home, I will further my research."

"You do that." Hiro said. "I guess we're out, Tadashi. See you… whenever I guess."

"Tadashi's neuro waves indicate he wants you to stay." Baymax said. "Perhaps we should do so."

Hiro turned back around to his brother. "Is Baymax right?"

"I…" Tadashi began. "I want to know how you've been. How everyone is doing. But I don't want anyone to get hurt."

"No one will be hurt. Not with Baymax around."

"Affirmative. I will do everything in my power to prevent injury." Baymax said.

"Okay." Tadashi said, after what looked like a brief struggle. "Why don't you guys sit down?"

Hiro nodded, and he walked over to the couch, and sat on the far end of it, leaving room for Baymax. The robot barely fit, making things a little cramped, but Hiro didn't mind.

"So, what have you been doing these last two years?" Hiro asked.

"Uh, odds and ends jobs." Tadashi said, sitting in the chair across from them. "I mostly stay off the radar and away from people. What about you? How is school?"

"Oh, I'm graduating next week. The new robotic nurse models are my top priority after that."

"Wait, you're graduating two years early?"

"Yeah, I aced all my classes. I basically took the ones I didn't know." Hiro said, shrugging. "Whatever, it works. I get to graduate with everyone now."

"Wow." Tadashi said. "I'm proud."

"I am as well." Baymax said. "Though, I have my worries that the more time you are home, the less time I will be able to spend with the hairy baby."

"Why?" Hiro asked.

"He does not like you." Baymax said. "And he has yet to come near me when I am near you."

"Oh, well. Try catnip. It works for cats."

"I shall research that when we get home." Baymax said. "Thank you, Hiro."

"Can I ask what a hairy baby is?" Tadashi said, with a raised eyebrow.

"Oh, it's Baymax's nickname for Mochi." Hiro said. "They get along really well."

"Wow. Impressive." Tadashi said. "Did you do any programming on him to make him seem so human?"

"No, Hiro did not." Baymax said, proudly. "I have learned a lot on my own."

"Yep." Hiro said. "I haven't touched him. Other than to tweak a few things. He has free will to activate on his own."

"Really?" Tadashi said.

"I enjoy it a lot." Baymax said. "It allows me to catch up on movies that Hiro has already seen."

"M-movies? He likes movies?" Tadashi said.

"Yeah, mostly action." Hiro replied.

"And horror." Baymax. "I do enjoy horror."

"You and Aunt Cass are too much alike." Hiro said, laughing. "If you start stress eating, I swear…"

"I cannot stress eat. I am a robot."

"It's an expression."

"Oh. I shall add that to my database." Baymax said. Hiro smiled at his robotic friend, before turning to his brother, who watched them with a shocked expression.

"Wow." Tadashi said. "He's so … different."

"Hiro, it is getting late. Your Aunt told me to have you home soon. Would you like me to call her?"

"No." Tadashi said, before Hiro could. "You need to go anyways. I don't want you out too late."

"You can come with us." Hiro said, hopefully.

Tadashi gave a sad smile. "I'm sorry Hiro. I really am."

Hiro sighed, and nodded. "Okay. Is this the last time I'm gonna see you?"

"No." Tadashi said. "I'll be in contact with you again soon, kid."

"Not a kid." Hiro reminded him. "I'm graduating college."

"You'll always be a kid to me, Hiro." Tadashi said.

Hiro didn't say anything as he stood up. Before Tadashi could blink, Hiro ran over to him, and hugged him, pressing his face against his chest.

"Hiro!" Tadashi said, and he could feel his brother tense up.

"I'm fine." Hiro said. "You're fine."

It took Tadashi a second, but he slowly wrapped his arms around Hiro, who smiled. Maybe this was a step in the right direction.
