Hi, my lovelies! Okay, though this isn't the 4th chapter of TMoTT, it is something I've kinda gotten into. I've become obsessed with Big Hero 6 ever since I watched it back in December. I loved it so much I watched it twice in three days! And though I did request an author to write me a fic, I decided to work on one of my own. Some of you may realize by now that dark themes is my forte. I guess it comes from experience. *grins maniacally* This may or may not be a one-time thing with the BH6 fics, but I hope you all enjoy regardless.

WARNING: SPOILERS (for those who know what to look for)!

Hiro Hamada knew he was a genius and was good at many things. At the tender age of fourteen, he had already graduated high school. He was capable of creating new and innovative products capable of bettering the world (or at least San Fransokyo). He was able to attend a great college where he could better himself and his inventions. He was part of a superhero group with his friends.

One thing Hiro wasn't really good at was emotions.

When Tadashi had been lost in the fire, he had simply bottled his turbulent emotions and tried his best to blank out of reality. Sure, he had had times when he cried himself to sleep in the warm arms of Baymax, but that didn't mean he ever talked much about Tadashi's death. He just…shut people out. If he didn't care about people, he wouldn't be so lost without them when they left.

When Tadashi had left, he had been so unprepared for the onslaught of pain that pierced his heart and body. It was an indescribable type of pain that filled his entire being and overflowed still onto others. It was emotional, physical, and psychological. He hurt all the time, sometimes attempting uselessly to curl into a ball in order to elevate the pain, to no avail.

Hiro, being the genius he was, knew that when people were depressed, they sometimes took their lives. It was pretty highlighted in history, though it was much lower statistically now. He didn't like to think he was depressed, because that meant people would feel sorry for him and try to help. They would take him to a therapist who would tell him suicide was a coward's choice. And Hiro wasn't a coward.

It didn't mean Hiro didn't think about it a bit from time to time.

It wasn't that he was unsatisfied with his life. No, if he wasn't in such pain all the time, he would be able to think about how well his life was, even though Tadashi had passed. He just missed Tadashi. Tadashi had been the only thing that kept his life in some semblance of order. Tadashi in his life had kept him satisfied, now that he thought hard about it.

He just wanted his big brother back.

His brother was all he wanted. He hadn't even wanted his parents back this much when they died. Now, Tadashi was all he wished for all the time, day and night.

So, Hiro had decided that it didn't matter what his friends and Aunt Cass would think of him later; he would reunite with his brother. Even if people thought it was the coward's way out. He was no coward, but he was determined to see his brother again.

He had made sure Baymax was given the instruction to take care of his friends and Aunt Cass no matter what happened to him, then promptly shut the white marshmallow down in his suitcase, knowing that one of his friends would know to activate Baymax at some point to question him about his whereabouts. It would be useless, considering he'd be dead. And his body wouldn't be far, anyway.

Hiro knew he shouldn't make any pained noise or sign of distress lest Baymax wake up and save him, so he made sure his method was relatively quick so he wouldn't be able to scream out. A simple robot experiment gone wrong would ensure no one would think he had taken his life. The blades on his newest bot could break off from their faulty magnetic hold and slice him open.

That is exactly what they did, and his mangled and bloody body was exactly what they found. His neck had been torn open, head almost completely disconnected from the shoulders. It had been a gruesome sight for Baymax, Aunt Cass, and his friends to find in the garage.

He had measured and figured out the probabilities exactly. His measurements had been perfect and precise.

Precise enough to kill him successfully, but sloppy enough with the other blade to make it look like a horrifying accident.

Hiro Hamada knew he was a genius and was good at many things. He had been able to deal with his pain and hold back his tears for a while with some modicum of success. He had been able to trick his friends and family into believing he had died creating the things he loved, having finally gotten back into college and quickly becoming a top student. He had been able to keep his remaining family safe (his friends counted as family) with the help of Baymax's last command. Even if he had had some trouble with those things, he was pretty good at being thorough with it. He was also good at dying.

One thing he was not good at was ever forgetting his brother, his Tadashi.

Yes, it was short, but I thought it turned out pretty good. And please, if you review, no flames or objections about how Hiro wouldn't do such a thing and that he would realize it's not what Tadashi wanted. I ALWAYS make things take a dark turn. My plot bunnies are vicious creatures that take sadistic joy in your pain, and feed on the tears of the innocent. Nevertheless, I hope you all review and say what you think in a polite fashion. Should I write more BH6? Simply stick to HP? Make something fluffier? Leave it all in your review!
