When Wilzig is taking CX404 to his lab, two scientists can be seen carrying a covered-up dead body on a gurney. Once the camera focuses on the green hand of the body, it is presumed that it is the hand of a dead Super Mutant, a type of humanoid mutant resultant of exposure to the effects of F.E.V. (Forced Evolutionary Virus), as well as a type of enemy/character whose presence is commonly seen in every Fallout game.
