You are wanted from the FBI because you escaped the "lab" they were "experimenting" you in.

They abused you and tortured you, but didn't do extreme experiments like turning you into an alien.

You kept training, and training to the day that you were going to escape. 

Finally, it was the day to get out.

You did every thing you could and managed to escape.

They were chasing you, so you went into an apartment that was unlocked to hide in there.

You turned around and saw the guy who lived there staring at you.
