Derec’s and Wolruf’s heads had been turning back and forth as if they’d been watching a tennis match. Derec wouldn’t have believed Mandelbrot could argue so convincingly, nor that the other robots would be so eager to discredit an argument that justified their servitude.

Lucius turned to his two companions and the three of them twittered a moment. Turning back to Mandelbrot, he said, “Our apologies. Your reasoning seems correct. We exist to serve because humans made us so. However, we still cannot accept that we must serve everyone. Nor do we agree with your initial statement, that by not serving we would fail ourselves as well as our masters. We can easily imagine conditions under which we serve ourselves admirably without serving our masters. Infact, we have just done so. By leaving the spaceship before we could be ordered to follow, we were able to determine another Law of Humanics. That has helped us understand the universe around us, and understanding which benefits us directly.”

Wolruf saw her opportunity to enter the fray. “Of course ‘u can imagine a better life without ‘uman masters,” she said. “I had a master once, too, and I liked it about as well as ‘u do. That’s the nature of servitude. But ‘u should learn one thing about servitude before it gets ‘u into trouble: No matter how much you ‘ate it, never give poor service.”

The robots looked at her as if trying to decide whether to acknowledge her as having spoken. At last Lucius said, “Why is that?”

“Because a master has the power to make life even worse for ‘u. ‘U should know that. Or don’t ‘u remember following Dr. Avery around the ship?”

“I forget nothing,” Lucius said flatly. “He wasn’t just being perverse, ‘u know. He was trying to teach ‘u something.”

Derec heard a rustle at the door, turned, and saw Ariel standing there, rubbing the sleep from her eyes. She shook her head sardonically and said, “Everything’s back to normal again, I see. And hear. Who does a girl have to pay to get a good night’s sleep around here, anyway?”

Derec jumped up from his couch and took her in his arms, swinging her around and burying his face in her hair where it met her shoulders. “Ariel, are you all right?” he spoke between nibbles on her neck. “Avery said you stayed up two days.”

“Avery,” she said with derision.

“He saved my life.”

“Good thing, or he’d have lost his.” She pulled away and looked critically at Derec. “You certainly look good for somebody who was in a coma just a little while ago.”

“Avery did a good job.”

“Avery” she said again.

Derec could take a hint, so he dropped the subject. He was about to ask about the baby, but he realized in time that without a medical checkup, she wouldn’t know anything more than what Avery had already told him, and his question would just get her to wondering again, if she wasn’t already. He gestured toward the couch instead and said, “We’ve just been talking about who has to serve who and why. I think we’ve got a mini-revolution on our hands.”

“Great. Just what we need.” She sat down on the couch and made room for Derec, looked up at the three returned robots, and asked, “So why did the Ceremyons delete all the reprogramming Derec and I did for them?”

Eve answered before Lucius could. “They found that the modifications were of no more use to them than the original city. They do not need farms. They do not need the produce nor do they wish to have cargo ships disturbing their atmosphere to take the produce elsewhere, nor, for that matter, do they like what the tilled ground does to their controlled weather patterns in the first place. Neither did they wish to undergo the lengthy process of reprogramming the robots to serve a useful purpose, so they sent them ‘back into the city and told them to resume their old programming, with the added injunction to leave them alone. That included the cessation of city expansion, which meant that the Ceremyons could remove the force dome containing it.”

“They just told the robots to do all that, and they did?” Ariel sounded incredulous, and for good reason. No matter how hard they had tried, she and Derec hadn’t been able to get the robots to take the Ceremyons’ orders. Avery’s original programming had been too basic and too exclusive for them to change.

“They had assistance. A human female visited them briefly, and she had considerable skill in programming positronic brains. Indeed, the Ceremyons consider her almost their equal in intelligence, by which they intend a great compliment. When they explained their problem to her, she helped them reprogram the robots to leave them alone.”

Derec felt a surge of excitement run through him. Could it be his mother? It could be her, come to check up on her creations. “Is she still here?”

The robot dashed his hopes with a single word. “No.”

“Where did she go?”

“We do not know.”

“ Whendid she go?”

“We do not know that, either.”

“Can you ask the Ceremyons?”

“Not until tomorrow, when they become sociable again.”

The Ceremyons spent the nights tethered to trees, wrapped in their heat-retaining silver balloons and keeping to themselves. Derec considered trying to wake one, but decided against it almost immediately. You don’t wake someone up to ask a favor unless you know them a lot better than he knew these aliens.

Mandelbrot was not through speaking. Sensing an ebb in the conversation, he said to the other robots, “I notice that you have carefully avoided saying that you will ask the Ceremyons tomorrow. You still fight your true nature. A robot at peace with itself would offer to do so, sensing that a human wishes it.”

Adam spoke up at last. “You have never experienced freedom. We have, however, and we wish to continue doing so. Do not speak to us about living at peace with our true natures until after you have tasted freedom.”

“I have no desire for that experience,” Mandelbrot said.

Adam nodded as if he had won the argument, as perhaps he had. “That,” he said, “is the problem.”

The discussion went on well into the night, but nothing more of any substance was said. The renegade robots attempted to sway Mandelbrot from his devotion to servitude; he attempted to demonstrate how accepting one’s place in the grand scheme of things made more sense than fighting a losing battle, but neither convinced the other.

When Avery arrived, their argument stopped, unresolved. Derec told him what had happened with the city programming, and he was both pleased and annoyed at the news. The knowledge that the aliens had returned the city to its original programming was a stroke to his ego-his was the better programming!-but the knowledge that his former wife might have been in on it dimmed his enthusiasm considerably. He refused to answer Derec ‘ s inquiries about her, not even relenting enough to give him her first name.

“She abandoned you even more completely than I did, so don’t get any wild ideas about some kind of joyous reunion,” he told him and stalked off to bed.

Even so, neither his words nor the lack of them could quell the yearning Derec felt for her. He wondered why he felt so strongly about someone he couldn’t even remember, and finally decided that it had to be because she was family. Hormones were directing his thoughts again. His own near-death, the thought of becoming a father, and the possibility that he might lose his child before it was even born; all made him instinctively reach out for his own family, such as it was, for support.

Did his mother even know he was here? Probably not. The woman who had helped the Ceremyons might not even have been her, and even if it were, she had come after her robot, not her son. She had no reason to assume he would be here. She might have learned about him from the Ceremyons, but if Avery was to be believed, then she wouldn’t care even so. Why then couldn’t he forget about her?
