They were sitting beside the tank, which had been returned to the usual place. A tree rustled in the artificial breeze and the grass around them had been torn and trampled by the guards. It seemed more peaceful because of the violence which had lately swept over them. Now it had ebbed and it would never come back. Jordan teetered beside the tree. "We'll find some way to get Anti out of the tank," he said. "When Nona comes back maybe we can rig up a null gravity place--something to make Anti more comfortable. And of course we've got to continue the cold treatment." "I can wait," said Anti, "I've already waited a long time." Docchi glanced around; his eyes were following his mind, which was wandering and searching. "Now there's no need to worry," said Anti. "The guards were rough with some of the women but plastic tissue doesn't feel pain and so they escaped with fewer injuries than you'd believe. As for Nona, well, she can look out not only for herself but the rest of us as well." It was almost true; she seemed fragile, ethereal even, but she wasn't. And her awareness began where that of normal humans left off. And where her perceptions ended no one knew, least of all herself. Right there was a source of trouble. "I think we should start looking," said Docchi. "At the last moment, upset at leaving and not knowing or caring who she was, one of the guards might have----" The enormity of the thought was too great to complete. "Listen," said Anti. The ground vibrated, felt rather than heard. "As long as the gravity is functioning can there be any doubt?" In his mind there could be. Nona had started it but once the gravity computer was informed of the nature of the universe there was no reason to suppose that it wouldn't keep running indefinitely. It existed to perform such tasks. It didn't actually have volition--but that applied to stopping as well. "I think I can convince you," said Jordan. "First you'll have to turn around." Docchi scrambled to his feet and there she was coming toward them, fresh and rested. There was a smudge on her cheek but she might have got that from some machine she'd stopped to investigate on the way here. Her curiosity was not limited and there was nothing mechanically so insignificant that it escaped her attention. "Where were you?" asked Docchi, expecting no reply. She smiled and for a moment he thought she knew what he asked. He was relieved that she was safe--and that was all. Something was missing in the reactions he expected from himself but he couldn't say where. At one time he had thought--and now he no longer did. Perhaps it was an expression of the new freedom they had all achieved. Jordan looked at him quizzically, half penetrating the screen he'd thrown over his lack of emotions. "It's not as bad as you think. She understands some things. Machines." And a machine he was not. He wasn't even a complete human. Perhaps that was where the difference was.
