Why do guards and bandits and other assorted badies have such drastic memory loss right after they find the bodies of their dead comrades. "...Must be my imagination..." No, it wasn't your imagination! You pal over there, he's dead! I just killed him, and you just discovered the body! How can you just go back to patrolling your post like nothing ever happend!!
First person: *stumbles upon body* "Oh my! What happened here?" *reaches down to check for valuables... I mean pulse, casually moves along*
Second person: *stumbles upon body* "Oh my! What happened here?" *checks pulse, casually moves along*
Third person: *stumbles upon body* "Oh my! What happened here?" *checks pulse, casually moves along*
etc...
