Galing said: “Our mistake was in not monitoring developments in the outside world as closely as we should have. We knew things had changed, but we didn't know how much they had changed, and therefore we took inadequate precautions. The Overmaster, through various of its mobile components — mosses, fungi — infiltrated the lowest computer cell blocks and even the fusion power plant beneath the last public level of the pyramid. Taproots breached nearly every computer memory bank with access to all our records; it learned all there was to know about us — especially, you. The Overmaster could not get to the upper levels of the computer, because they were on floors that had no direct contact with the earth; therefore, it couldn't open the door and come in after us. Apparently, it decided we could live and not be a threat to it — but you must be given absolutely no quarter, no chance.”
“Why did it think I was so much more dangerous to it than the rest of you?”
“Because you'll play the most vital, maybe the only vital, role in any war against the Overmaster,” Gina said.
“We need you if we're to restore the earth,” Galing said. “For one thing, only you can create more of us, because the operation of the vats requires a womb-born man whose fingerprints are on file in the installation's computer. Androids were never permitted to make more of their own. Certainly, we could mate and produce children… But in the decades that we would need to raise and educate a community opposed to the Overmaster, we would lose the battle. And only you can give Brian his face again. And only you have the first-hand, pre-disaster knowledge that we need to channel our energies in the proper research.”
Joel stood away from the tank. “But when the Overmaster had control of me in the pod, why didn't it kill me?”
“It couldn't,” Galing said. “All it could do was feed you subliminal data. And it did that with a vengeance. Prior to the start of that first Disorientation Therapy Puzzle, the Overmaster fed you highly compressed subliminal propaganda which reinforced your neuroses. It turned your distaste for androids into active hatred, then ballooned that hatred into fanatical loathing. It made an eventual cure remote indeed. So… When you went through the first Disorientation Puzzle so differently than we'd anticipated, and when, at its conclusion, you were a great deal more bigoted than you had been before we'd put you in the pod, we knew something serious had gone wrong. Indeed, your neurosis was now a psychosis, so fierce that it would now have endangered the future of the entire installation. Therefore, we put you to sleep, and we began to search for an answer.”
“And you discovered the Overmaster.”
“Only after a full decade of probing,” Galing said. “But when we finally knew it existed, we were quick to find the breach in the pyramid, the computer tap, and the propaganda tape link to your pod. We purged the computers of contamination, used the Overmaster's propaganda tapes to structure pro-android propaganda to cure you. That was only a partial success, so we were forced to put you through the Disorientation Therapy Puzzle four more times to fully cure you.”
Joel ran his fingers through his damp hair. “But now it's over at last.”
“No,” Allison said, “it isn't over.”
Both men turned and looked up at her. She had come awake while they were talking. She had slid to the edge of the seat and was gazing down at them from the open door of the tank's cab.
“It isn't over?” Joel asked, perplexed.
“She's right,” Galing said. “It's taken nearly a century and a half to undo what the Overmaster did to you.”
One hundred and fifty years …
“Meanwhile,” Allison said, “we've been besieged. We're constantly on guard, waiting for the Overmaster to breach the pyramid again.”
“It wants to destroy us,” Richard said, “but it also wants to ruin all the things we've preserved of the Old World. It's made several attempts to open the freezers that contain the animal and plant samples, the Old World life tissues we'll one day use to clone new animals and plants. If those were destroyed, we'd never have a chance of restoring the Earth.”
“Sooner or later,” Allison said, “if we can't go outside and take the initiative, if we can't put the Overmaster on the defensive, we'll be finished.”
“It's already reaching into the upper levels of the pyramid,” Joel said. He told them about the deadly vegetation that he had encountered in the drain tunnels.
“We've got to burn that out and fast,” Galing said. “Before it gets to the main computer.” He turned to the other androids and gave them assignments.
Joel reached up and helped Allison down over the tank tread. When she was at his side he put his arm around her tiny waist as she put her arm around him. “It's not over after all,” he said. “This was the smallest battle. The real war hasn't even begun.”
She kissed him, leaned against him. She was warm, firm, slightly damp with perspiration. “It's sad in a way… Before the war could even be waged we had to purge you of old hatreds. Now, we have to build a new hatred in you. We have to make you share our hatred of the Overmaster.”
“After what I've been through,” he said, “I already do.”
“It's still sad,” she said.
“I guess it is.”
“And from now on,” she said, “the horrors won't be illusory.”
