"You...you killed her..." your brother stutters, staring blankly, as if he cannot accept what is before his eyes. After all, he thought he was creating a hero.... You also gape for a moment, but being the older brother, you had always been the responsible one, the one who had to think of the consequences, while your little brother ran headlong into any situation, and always managed to get away with it. As such, a dozen possible outcomes crashed into your head at once, and you knew your brother wasn't to be trusted. You figure a good offense is the best defense.
"The hell I did!! You're the one who did this to me!" you snarl at your brother, who looks down at you with a startled glance. "Therefore you caused her death and anything else that happens as a result! Whatever this place is, it'd be bad for you if news got out, wouldn't it? Try to pin any of this on me, and see what hellfire I'll rain down on you and whoever else is responsible for this!"
"This wasn't supposed to be- " your brother whimpers, using that same whiny voice he would pull whenever he couldn't handle the situation and wanted you to rescue him, even when you were kids. Usually, you would sigh, pat him on the head, or shoulder when he grew up, and assure him you'd find a way to fix everything. But not this time.
"Doesn't matter what it was supposed to be, this is what is happening," you snap, then turn away. "Don't follow me or look for me. I'm done with you."
You take off sprinting through the hallways, moving much faster than any normal child, faster than even an adult. In fact, you could probably rival a cheetah on a straightaway, although the tight corners are hampering your speed a bit. Nevertheless, you are trying to draw as little attention as possible. However, after bursting through a locked door, you find yourself skidding into a laboratory, where dozens of men and women in white coats standing at counters turn to look at you in shocked surprise. Cursing to yourself, you decide there's no point in being low-key anymore, and resolve to crash straight through the walls until you get out of this insane asylum. However, before you make a move, you hear a voice blare out over the intercom system, and realize that it belongs to your brother.
"Security teams to the building! We have a code red situation! Deploy all barriers and activate the disarming mechanism before the subject exits range!" you hear your brother shout. However, what no one other than you picks up - thanks to your enhanced hearing - is that just before the intercom is shut off, your brother whispers something to someone else in the room: "Thank god he put on the suit."
The suit! It's another trap! You reach down to rip it off, but find it just stretches, and realize it will take a few minutes even to remove it normally, as it is such a clingy yet strong material. At this point, the lab workers have fled, and you can hear alarms blaring throughout the facility. Knowing you don't have a second to waste, you remember something else your brother said. Something about "range." That's it! If you get far enough, whatever your brother did to the suit to control you won't work! Returning to your initial plan, you run straight ahead at top speed, intending to crash through every wall and get as far away as you can before your brother can do anything else to you.
