Chapter 2 (The Rain):

Hiro returned from school. He was cured from his common cold about a month ago. Finals were all over with and put the past, which means he didn't have to study so ridiculously long. That's a relief. The only problem now is that he didn't have anything to do when he got home. He tried to play his game, or watch TV or browse the internet but nothing seemed to entertain him now. The teenage prodigy was bored stiff, due to college not offering anything to him. After an hour, he ran up and collapsed on his bed, and groaned out of sheer boredom. A gentle hiss entered the air. Baymax.

"Hello. I am Baymax, your personal health care companion." The nursebot said his programmed greeting. Hiro turned and smiled slightly. "I heard a sound of distress."

"False alarm, Baymax. I'm just… bored." Hiro explained. The robot looked down, processing information. Today was not clinic night, so Baymax was free the entire day. Ever since that one night, Hiro never brought up Baymax leaving to work in the hospital full time. Baymax seemed to never bring it up too. The teenage prodigy definitely thought about it though. At first he thought about finding a way to mass produce the healthcare chips and to have Baymax work in clinics all around the world. It was definitely an idea to be explored in the future but the world wasn't ready for it. A lot of nurses would lose their jobs. Not only that, but Baymax was a machine that could learn anything with a capable chip and the right resources. And there's no way that Hiro will let go of Baymax, he was his best friend. Hiro was conflicted; he didn't know what to do. He didn't want to let his best friend go but at the same time too, he knew it was the right thing to have Baymax do what he was programmed to do. Preferably, he wouldn't want to think about it.

"Hey. How about we go for a flight?" Hiro suggested, shaking his thoughts away, pushing the issue even farther aside. He brought out his suit and Baymax's. He looked outside his window, the weather was much clearer than last week, although a couple dark clouds were over the horizon behind the tall buildings. This flight would have to be a short one, to prevent any dangerous conditions. Hiro began to put on his suit and helped Baymax. The nursebot was slowly learning how to put it on by himself; he mimicked Hiro's actions from time to time although he still needed help to put the whole suit on. He grabbed his portable suitcase just in case they needed to take off armor due to the storm.

They began the flight. Hiro would never forget the feeling. Flying felt like a never-ending rollercoaster and children (and even a couple of adults) looked in fascination, with their mouths agape. After all, it's not everyday that you see a teenage boy flying with a robot in the sky. He giggled almost entire the way, especially when Baymax did loops. Amusement parks were nothing in Hiro's eyes anymore. With Baymax, you could get just as much of a thrill and you didn't even have to wait in line.

They prepared to land. It occurred to Hiro how much Baymax actually learned from him. He mimicked a lot from him and he seemed to remember things. He even remembered how long the flight path was and the route. Hiro didn't have to maneuver him because he recognized the route and they went the same route every time.

They stopped and rested where they usually sat. The murkier clouds grew closer. Suddenly, something changed. Hiro felt guilty again. He felt like he was using his best friend for mere entertainment purposes. Baymax wasn't used for flight; the whole reason why Hiro actually added that feature in is so that he could defeat Callahan. That was long time ago, but Hiro remembers one point where he wanted to kill Callahan, and he tries his hardest to push those thoughts away from his memories. The point is… Baymax was made to help the sick, injured, and heartbroken. Sometimes Hiro wonders if the nursebot feels strange for doing these activities that don't adhere to his programming and his purpose.

They both stood there in silence, the sun was setting over the horizon, the rays reflected across the dark gloomy clouds. Baymax noted that his patient was being awfully quiet. He informed him about this, hoping that more information can come from it, although Hiro didn't say anything in response. A couple raindrops fell from the sky; the droplets were now visible on Hiro's helmet. A roaring thunder was heard deep in the distance.

Rain. Hiro always hated the rain. It reminded him of Tadashi. It reminded him of the funeral. "Hiro, I suggest that you go indoors as soon as possible. At this height, you are susceptible to lightning strikes. We may need to walk home to prevent any possible danger." Baymax stated factually as he stood up. Hiro mounted his back. "Yeah, let's go home, big guy." Baymax recognized how gloomy his patient's tone of voice was. The nursebot started to "worry".

As they flew, Hiro noticed a sudden change in his emotions. He felt suddenly nervous, as if he should make a decision now. He knows it would be difficult to let him go if he was in his house. Baymax seemed to make everything easier, and Hiro wanted to offer that to other people in need. His brother wanted to help a lot of people, and he wanted to do the same. He heard the rain outside growing more intense once they started to fly. "Wait, Baymax!" The nursebot slowed down, listening to Hiro's commands. "At this height, it is dangerous for your health. Do you want me to land, Hiro? "

"Yes." Hiro agreed and Baymax swooped downwards and landed safely. They had to walk home to rest of the way. At least the suits were somewhat warm and waterproof.

During their trek back home, Hiro noticed Baymax's clinic. He felt nervous again. "Baymax?" He felt like he should make the decision now and he already felt guilty. Baymax turned to face him and repeated that they should go home as soon as possible, and that the lighting is only getting worse. "Yeah, I know that, buddy. I'm going to take off your armor, okay?" Hiro instructed. He felt really upset almost to the point of tears. He took off every single part of his nursebot's armor and put it in his bag. Grabbing his hand, he led him outside of the hospital doors. By this point, Baymax wasn't as confused about his patient's recent behavior.

Hiro looked at Baymax, his stomach twisted in knots. He knows this is the right choice. Baymax is going to help a lot of people, and potentially save a lot of lives in the process. His fists were clinched, his face was red and he was about to cry. He hugged his healthcare companion and Baymax returned the favor. After they finished the embrace, Hiro smiled sadly, despite his tears. He went inside to inform the doctor; he offered money in exchange for Baymax but Hiro refused. He looked at Baymax one last time and formally said a goodbye. "I'm satisfied with my care." The only time he went back in that hospital was to drop off the nursebot's charging and storage case.

And that was the last time that Hiro saw Baymax this year.

AN: ….I felt like this was rushed. It is currently midnight in my area and I'm tired as hell so I'm sorry if there are any errors in this. I'll probably rewrite it later but I didn't want to keep you guys waiting too long for this because my rewrites take at least another week. I apologize for the hiatus; I'll try to get better at updating my stories more often. But thanks for staying with me and I'm going to try my best to update once a week until I finish this story!
