He cannot get to that gun. I crawl and when I am within his range, shoot him on the head.
I need to get out of here, I need to live. I don't want to die today. My whole body screams at me but I have to go and I have to go now.
I don't know where the other man went but I know that he is somewhere. I am in this room, trapped with two dead bodies, that makes me compromised, and to be honest, I don't want to be in here, I doesn't want to be the third body.
I crawl, out of the room, as silently as I can and just as I am passing the second man, I take his gun and discard the other one. I don't hear anyone or anything, its dead silent, save for the waves crashing on the boat, making the boat sway gently.
