A powerful typhoon strikes the surface, and the Habitat crew is forced to stay in the Habitat several more days. During that time, a series of tragedies strikes the crew, including attacks from aggressive jellyfish and a giant squid, and equipment failures in the base, which kill Ted and the team's support staff. The survivors, Beth, Harry, and Norman, believe Jerry is responsible. While waiting for rescue, the three realize that the hazards are manifestations of their own fears: all of them have entered the sphere, which has given them the ability to make their imagination real. Norman discovers that they had misinterpreted the initial messages from Jerry, and that the entity speaking to them through the computers is actually Harry himself, transmitted while he is asleep.
