Entropic cascade failure
Unusual side effect which emerges after a couple of days of identical living matter co-existing within the same dimensional universe. This is a direct result of a person who is already in the incoming reality, arriving through the quantum mirror. It is marked by violent and painful convulsions as the foreign matter is, in effect, rejected by the host reality.
Entropic cascade failure does not occur if a person's counterpart in another realm is deceased.
Point of View - Dr. Samantha Carter emerges through the quantum mirror to find her counterpart, Major Samantha Carter, in the same realm and, after a period of time, begins to fall prey to entropic cascade failure.
Ripple Effect - Dr. Lee hypothesizes that the reason so many alternate realities converging with the same personnel is not causing entropic cascade failure is because of the naturally close proximity between the realities.
