Not a bad guess, Conan. But, there are a few inconsistencies between your guess and the riddle. For starters, I think Worker 7-new does issue a warning to intruders and to the researchers. The riddle says no warning. Secondly, they are told to evacuate or retreat within 30 seconds. The riddle says "don't try to run". Thirdly, other than Reis' little problem, I can't think of any innocent life that hangs over our heads in that scene. I also mentioned that this "character" is from a cut-away scene, not a battle prelude. Keep the guesses coming folks.
