Hello guys, how have you been?

I'm sorry this took a while, but I really needed to take a break from writing. My life has been especially busy in this past month, but things are slowly coming back to what they were. Also, I obviously hit a wall with this story. I had to think a lot to decide how to continue this, I hope I did the right choice.

This is much shorter compared to some previous chapters, but keep in mind that this is a transition chapter.

Thanks for everyone who has been following this; I hope you enjoy this chapter!


The shot made a noise that, though not very high, was enough to make everyone present cover their ears and close their eyes. Even GoGo, though she could only use one hand since she was holding the gun and therefore her uncovered ear started to hurt.

A gray smoke filled the room, being followed by the sound of coughing. The small explosion was able to push everything in its way a few inches back, and it even knocked Fred who fell over Wasabi. When he regained his balance, Tadashi rushed to the door to open it so that the smoke would leave the house, and he stumbled on a chair and almost fell over on his way due to the fact that his vision was being covered by the smoke.

As soon as the door was open, the smoke started to fly away and soon enough Tadashi could see his friends again, but his vision was really blurry. He rushed to help Wasabi and Fred to stand up and tapped Honey Lemon's back until she stopped coughing. Inhaling that polluted air that was full of chemistry had made them all pretty dizzy, so it took a while for realization to come to Tadashi. When it did, however, he gasped as he turned around and rushed to where Hiro was. In his hurry, he accidentally knocked Fred who fell over Wasabi again.

"Hey!" Wasabi cried out as his back hit the floor, but his expression of pain changed into a worried one when he also remembered what they had just done.

Tadashi stopped in his tracks, chocking when he tried to breathe. His mind was racing so fast he couldn't concentrate on anything. He was so lost in his thoughts that he was startled when Honey Lemon approached him and put her hand on his shoulder, but he quickly looked back at Hiro. GoGo dropped the gun and went to Tadashi's side, being followed by Fred and Wasabi; but they took a little longer because they had had a hard time trying to stand up.

Hiro was on the floor, on the same spot he was before GoGo shot him. He was lying in a fetal position, his arms covering his head as if he had tried to protect himself from something. However, his loose position let them all know that Hiro wasn't awake; his chest was going up and down so slowly that it almost seemed to be still.

"Is he even alive? Ow!" Fred questioned, but cried out when GoGo firmly prodded him with her elbow, motioning for him to be quiet.

Tadashi fell to his knees and attempted to approach Hiro, but just when he was about to move, Hiro woke up. He let out a little grunt as he moved his arm away from his face and got up on his right elbow. After rubbing his brown eyes, he slowly opened them and blinked to adjust his vision that was so blurry that he thought he had gone blind for a second. Once he was able to see again, he raised an eyebrow when he took notice of all his friends and his brother staring at him.

"Uh, what are you all looking at?" Hiro asked with a raspy voice before coughing as he sat up on the floor. He thought of standing up but gave up when he felt that his legs were numb. His head ache something awful and his throat was dry like it had never been before, but physically speaking, he seemed to be fine.

And without a doubt, he was fourteen again.

"Hiro." Tadashi sighed with a smile. He crawled until he was close enough to touch Hiro and sat on his knees in front of his brother, but all he did was look at Hiro for a few seconds. He felt his heartbeat slowing down and allowed himself to breathe normally again as concern left his body. Hiro shook his head and looked at Tadashi's eyes before cocking his head in confusion.

"Why are you-?"

Hiro was interrupted when Tadashi suddenly wrapped his arms around him and brought him closer in a hug. He was confused and looked from side to side when he noticed Tadashi was sniffing as if he was about to cry. Not knowing what to do, he awkwardly started to pat Tadashi's back, but he gasped when his older brother tightened his grip on him and made it a little hard for Hiro to breathe.

"I'm so glad you're fine." Tadashi said under his breath when he pulled away, yet kept his hands on Hiro's shoulders. Hiro raised an eyebrow when he saw Tadashi's watery eyes and huge smile. Then he looked over his brother's shoulder and took notice that all of their friends were looking at him with water filled eyes.

"Would anyone mind to explain me what's happening?" Hiro asked, taking Tadashi's hand off of his shoulder and backing away a little. He felt overwhelmed with all of those eyes staring at him.

Tadashi's expression changed. His smile became a straight line as he gulped. His eyes remained watery, but the joy in them disappeared and was replaced by what seemed to be disappointment. He softly shook his head and took a deep breath, as if speaking required a huge effort. "You mean you don't remember?"

Hiro rolled his eyes and snorted, tired of not getting any answers and feeling the pain in his head increase. "Don't remember what?"

Tadashi's heart sank inside his chest and he felt like he was about to cry. He didn't know exactly what he was expecting would happen when they turned Hiro back to his normal age, but he surely hoped Hiro would remember what happened. If he had forgotten everything, then all of the promises they had made each other, all of their talks, all of the moments they had shared that Tadashi hoped would help them to grow closer; everything that had happened that week had been in vain.

As if none of that had ever existed.

"Hum, oh my, look at the time!" Honey Lemon said as she forced a giggle and nodded toward the front door, nudging GoGo's arm. "We should totally be going, our parents must be worried. And it seems that Tadashi and Hiro have some catching up to do too! So yeah, see you soon, Tadashi! Goodbye, Hiro!"

"Oh, yeah, and I'll be taking this with me." GoGo said as she picked up the gun that she had left on the floor. "We don't want to have any other accident now, do we?" She then turned to Wasabi and Fred and noticed that neither of them seemed to be getting the hint that they needed to leave Tadashi alone with Hiro so they could talk.

She and Honey Lemon started to push Wasabi and Fred toward the door. They awkwardly nodded as they waved goodbye to Hiro and Tadashi, even if the Tadashi was still staring at Hiro and didn't even seem to acknowledge that his friends were leaving until GoGo slammed the door shut and he snapped out of it, shaking his head. He looked over his shoulder and saw his friends leaving through the door of glass. Tadashi sighed and stood up, walking up to the door to lock it.

"So, mind to explain things now?" Hiro asked.

Tadashi sighed again and walked back to Hiro, reaching out. Hiro raised an eyebrow and reached out as well, taking his brother's hand and accepting his help to stand up. As soon as he was on his feet Hiro almost fell over, but Tadashi held his arm before he could hit the floor. Hiro looked down at his legs, confused as to why he couldn't walk properly and why he felt like he was sick. He slowly let go of Tadashi's hold when he finally felt able to stand by himself again.

"Come with me." Tadashi said dryly as he turned around and walked to the garage. Hiro tilted his head, but shrugged and followed his brother anyway.


"Are you going to tell me what's happening or not?" Hiro asked again, annoyed. He was sitting on a chair in the garage and watched as Tadashi seemed to be looking for something he hadn't told Hiro what it was. He seemed to be ignoring Hiro or just not paying enough attention to him; until he opened a closet and seemed to have found whatever it was he was looking for.

Hiro watched with curiosity as Tadashi took a big red luggage from the closet, walking up to Hiro and placing it in front of him.

"What's that?" Hiro asked, straightening himself up on the chair to get a better look.

"A robotic nurse I built. I just want to make sure you're fine." Tadashi looked over his shoulder and his eyes met Hiro's confused ones. "I'll explain later. Baymax, activate."

Hiro's eyes widened when the luggage opened and a white, round and fluffy robot inflated from there. He walked out of the luggage and approached Hiro.

"Wow, that's… That's something." Hiro said with a smile as he nodded and folded his arms in approval. He stood up and approached Baymax to get a closer look, not noticing that the robot was already scanning him. "You even installed a voice control? That's cool. Most people don't do that."

Tadashi chuckled. "It was you who kind of inspired me to make a voice control, actually."

"What?"

"I'm afraid my systems have been damaged." Baymax interrupted, turning to Tadashi. "In my data, it says that Hiro is a five year old kid, when he is in fact a teenager who is close to reaching manhood. I believe I'm not in a position to give any kind of health care until I'm submitted to a checkup and fixed."

"Wait, what?" Hiro blinked. "Why does he think I'm five?"

"Baymax, there's nothing wrong with you." Tadashi said, ignoring Hiro's question. "It's a very long story, but believe me, you are functioning perfectly. I need you to scan Hiro and tell me if there's anything wrong with him. Especially if there's any kind of internal damage or anything like that."

"Why would I even be injured?"

"Scan complete." Baymax interrupted Hiro again. "Hiro seems to be just fine, except for the fact that he has too much sugar in his body right now. He should consider having a healthier diet from now on. I recommend less candy and more vegetables. I will also update the data I have about him to a fourteen year old instead."

"Thank you, Baymax." Tadashi sighed in relief. "That's all I needed from you. I'm satisfied with my care."

Hiro watched as the Robot went back to his luggage and shrank, releasing the air he had inside of him. Once he was done, the luggage closed around him. Tadashi sniffed again as he picked it up and put it back in the closet with a sigh.

"So, a robotic nurse, yeah, pretty cool. Now... Can you please explain to me what's happening here?!" Hiro asked in an explosion. "Why does he think I'm five? Why did I wake up on the kitchen floor? How did you…"

"Hey, calm down." Tadashi said, rolling his eyes. "I'm sorry, ok? You'll understand soon enough. Let's go to our room. You sit down and calm down, and then I'll explain everything that happened, ok?"

Still used to the little Hiro that always obeyed him, Tadashi didn't wait for an answer.

"B-But..." Hiro stuttered as Tadashi softly poked him on the head and walked past him, going back to inside the house. He groaned in annoyance, tired of not getting any answers and being ignored; but followed his brother shortly after.


"Whoa, whoa, whoa." Hiro said, holding up his hands. "Let me get this straight. You and I went to your college so that you could show me that robotic nurse you invented, Baymax; but your lab was locked so you had to go outside to get the key in your motorbike and left me in the college. Then that Fred called me to show me his invention but that went wrong and he ended up turning me to a five year old kid again. And I was a kid for the whole past week until you guys were able to fix that gun today?"

They were both sitting on Hiro's bed and Tadashi had spent almost half an hour to explain everything that happened, which hadn't been easy since Hiro kept interrupting him to ask questions.

"Yeah, that pretty much sums it up." Tadashi nodded.

Hiro blinked and stared at Tadashi for a long time. "You're kidding me, aren't you?"

Tadashi tilted his head and rolled his eyes. Instead of answering, he reached for his phone in his pocket and unlocked it. Hiro watched as his brother opened the gallery and selected the most recent picture he had taken. Once it was on the screen, he handed the phone to Hiro.

Hiro raised an eyebrow as he took the phone, but his jaw dropped as soon as he saw the picture. It depicted the image of a young boy with messy hair and said boy held their cat Mochi on his lap. Hiro recognized the couch behind that boy as being the couch they had in their living room. It took him a whole minute of staring at the picture to finally take in that that boy was indeed him.

"But..."

"I'm not lying to you." Tadashi said. "That's what happened. You were a kid for a week. That happened on the day we left Aunt Cass on the bus station, remember? Actually, she comes back home tomorrow. We should get some rest since we have to wake up early to go pick her up and…"

Tadashi trailed off when Hiro abruptly returned his phone to him and stood up, angrily stomping his foot. Tadashi gasped in confusion and put his hand on his chest in surprise.

"Wow, thank you so much, Tadashi!" Hiro yelled in anger, pinching the bridge of his nose. "Do you have any idea how many plans I had for this week? I was going to go to so many bot fights and Aunt Cass wouldn't be here to stop me! Now she's coming back and you know how much she hovers over me. Do you even know how much money I could have won this week?"

Tadashi's jaw dropped as he stood up and held up his hand. "Wait, seriously? Hiro, that's what you're worried about? I just told you that you were a kid for the last week and… What makes you think I would have let you go to those stupid bot fights anyway if this hadn't happened? You know those are dangerous."

Hiro scowled at his brother. "Yeah, right, sure. I am fourteen and I graduated high school last year, I can take care of myself! Also, don't act like it's a hard thing to escape this house when you're here. You're always in that school anyway! You shouldn't even care for what I do!"

Tadashi bit his lower lip and he started to feel angry. It wasn't common for him to lose his temper, but hearing Hiro say he shouldn't care when all he had done the past week had been to keep Hiro safe made him fold his arms and he started to yell as well. "Well, you can't act like it was my fault!"

"Well, if you hadn't taken me to that stupid college it wouldn't have happened!"

"If you weren't so stubborn all the time I wouldn't have taken you there!"

Hiro stomped his foot again and turned around, looking for his Mega-bot. He found it on his desk and grabbed it, walking toward the door. Tadashi shook his head and jogged to reach Hiro, grabbing him by the hood of his hoodie. "And where do you think you're going, exactly?"

Hiro turned around and pushed Tadashi's hand away from him. "Where do you think? This is the last night I have before Aunt Cass comes back home, I'm going to try to compensate for the week I lost because of you and your friends!"

Tadashi took Hiro's robot from him. "No, you're not going. You're staying home!"

"No, I'm not!" Hiro said as he jumped and took his robot back, making sure to keep it behind his back so that Tadashi wouldn't be able to take it away from him again. "You can't tell me what to do!"

"Hiro, it's past midnight, bot fights are illegal, I'm your older brother and you promised me you would stop doing that! So that means you have to stay!"

"Oh, yeah? When did I even promise that?"

"A few days ago!"

"Hey, I can't remember anything from this week! How can I know that you're not lying about the things I did or didn't do? Go back to working on your stupid robot and leave me alone to my business!" He said as he rushed to the door.

"Hiro, come back here!" Tadashi said running after him. "I'm not letting you throw your life away like that! You should be using that brain of yours to do useful things! You can't…"

"Oh my God!" Hiro face palmed. "Not this again! You know what? Whenever you start with this speech I really start to wish you weren't my brother at all!"

Tadashi's jaw dropped as his body froze at his brother's choice of words. He gulped and bit his lower lip, taking a deep breath. He looked at Hiro with an angry face and then looked to the side, avoiding eye contact. "Go do whatever you want to do, since you don't seem to need me anyway." He said, not yelling anymore.

Hiro's eyes widened as if he wasn't expecting Tadashi to say that. He seemed to hesitate for a few seconds, but then he looked at the open door of their room and ran to it before Tadashi could change his mind, disappearing into the living room.

Tadashi took a few steps back, appalled, before turning around and going to his part of the room. He sat down on his bed and looked around, letting his mind be filled with memories of the past few days. Then, images of the fight he had just had with Hiro started to appear as well, and he slowly started to wrap his brain around it.

As soon as he comprehended what had just happened, he buried his face in his hands and started to cry. His head shot up when he heard a noise that he recognized as being the front door being slammed closed, meaning Hiro had left the house.

Tadashi gasped as more tears rolled on his face.

What have I done?


What, you thought that Hiro would wake up and tell his brother he was sorry and that he loved him and everything would be fine? Pft, that would be boring! We still have a few chapters to go before this story is done.

But let me tell you this: not everything Hiro says is true. Consider it a spoiler.

I'm sorry for the angst in this chapter, and maybe it was a little OOC. But I promise everything will be explained very soon.

Thanks for reading!
