So don't talk, Tom growled silently, I can keep warm just by hating you, Jason.

He worked through the frigid night, struggling ant-like with huge pieces of equipment. Slowly he assembled the big parabolic mirror, the sighting mechanism and the atomic convertor. With dreamy motions he started connecting the intricate wiring systems.

And all the while he raged at himself: Why? Why did it have to be this way? Why me? Why did I agree to do this? I knew I'd never live through it; why did I do it?

He retraced the days of his life: the preparations for the flight, the arguments with Jason over exploring the cities, his trek from Chicago to the settlement, the aimless years after the radiation death of his two boys and Marjorie, his wife.

Marjorie and the boys, lying sick month after month, dying one after the other in a cancerous agony while he stood by helplessly in the ruins of what had been their home.

No! His mind warned him. Don't think of that. Not that. Think of Jason, Jason who prevents you from doing the one thing you want, who is taking your life from you; Jason, the peerless leader; Jason, who's afraid of the cities. Why? Why is he afraid of the cities? That's the hub of everything down there. Why does Jason fear the cities?


It wasn't until he finished connecting the satellite's last unit—the sighting mechanism—that Tom realized the answer.

One answer. And everything fell into place.

Everything ... except what Tom Morris was going to do about it.
