There is not enough room on the ship for the both of you. You can't have this passenger upsetting your work performance. Who the hell does he think he is. His smarmy stares like he knows me too well. No..I will wait till they are closing the kitchen and stab him with his own knife.
You sneak into the kitchen and find the knifes right where you thought you might and slipped into the bathroom. From there you hid in the closet with the cooks shirts, a full rack of white coats and white shirts.
The cook is half naked. You leap out and plunge the knife into his chest. His arms jerk to block you and then attempt to grasp the blade. You kick him in the balls and he jerks over on his side. You pull the knife out and jab up his rib cage into his heart. You finish with a stab to the neck down into the ribcage from the top.
Rack of white coats splattered in red.
You stand over the body and begin to fade. You look through your arms and legs.
