"Nononono!" I get injected, yelling in pain, and he takes the syringe out. I squirm in the chair that I'm bound to. Red veins appear across some of my skin, and I yell in pain again. After a minute or two, my body goes limp. I then start breathing fast and then slow but hard.

"wh- How?! You're alive!" The guy makes a fist in anger.

I look at the man and spit at him. "Nothing will, hm?" I squirm, break out of my boundings, and launch myself at him with an experimenting knife. "Say hello to Nelson for me." I then stab him in the hard and twist, then pull it out.. He is dead, and I am free.
