Playing fallout 3, a zombie survival house mod, my companion Sam was shooting zombies, then i left for a hour, came back, he was dead, but the funny thing, he didn't look dead at first. At first, he looked like he was puking in the toilet, then i noticed his hand was completely shoved into the toilet. Was he grabbing for something in that toilet? Did a zombie come out the toilet and kill him, dragging his hand back into the toilet? My guess is, Sam was really hungry.
