Two

By the time the door bursts open I'm on my feet with my hand in the air, I don't care that they finally get to see what they've been looking for the whole time, I'm going to make sure it's the last thing on their minds.
The guards aren't different from what I remember them to be, same white armour, same wooden poles that they beat you with, same helmet with a reflective visor (this isn't the best time to point out that I look truly awful),I'll bet anything on the fact that it's the same cowards inside the suits too.
They make a move to come towards me, there's about 5 of them, but I move forward at the same time still holding my hand up, my palm facing them.

They draw to a stop, straining against my invisible wall slowly pushing them back, then all at once I flick my fingers and they fall to the floor, unconscious. I step  forward, delicately making my way between the arms and legs sprawled on the floor. When I get under the door frame I stand for a minute, deciding wether to go left or right. The guards came from the left, so I decide to go right, slowly I make my way through the maze of corridors getting more and more anxious at the fact that there seems to be nobody trying to stop me. The corridors are a maze, my head is a mess, it's safe to say I have no idea where I'm going.

That's when I hear it. Panicked yells somewhere close to me. I run down the corridor, kicking open every door ready to defend myself and what I can only assume are the others like me. The yells get louder, more frantic, I kick open door after door. Then I find them. I enter a room, barley having time to process what's going on, I look at the 4 people standing lined up against a wall shaking with fear, it registers in my mind that these people are only kids the youngest looks to be about 6 years old, the oldest about 13, then I look to the 4 guards standing a little less than 6 feet away from them with their guns aimed to the children. I yell and shove my hand out, and invisible force knocks down each guard, but not before 4 loud gunshots ring out. All 4 kids fall to the ground, I scream in despair, knowing that if I had been seconds faster then maybe they would have lived. But I wasn't faster, and their death is on my hands.

I look at the children. 2 boys, 2 girls. First a boy, about 13. His blonde hair sticks to his forehead with sweat, his pale skin looks almost translucent under the lights, his eyes are still open but unfocused. Next a girl, maybe about 10, black hair cut to just above her shoulders, a small nose, parted lips, dead eyes. Another boy, probably not even 9 years old, Asian, short black hair, blood on his shirt, just as dead as the rest. And last, the girl. The youngest one there, dark curly hair, big brown eyes, small freckles over her cheeks and nose, her chest moves up and down jaggedly and she lets out a small gasp.

She's alive.

Alive.
