One of them walked past carrying a test tube filled with cloudy liquid. Derec cleared his throat noisily and said, “We’ve got a problem here.”
“That is unfortunate,” the robot answered without pausing in its stride. “How may I help?” It walked on over to a centrifuge, put the tube inside, and started it spinning.
Derec felt momentary annoyance at talking to a robot who was too busy to stop for him, but some remnant of his thoughts on the trip over kept him from ordering the robot to drop what it was doing. This robot, at least, had a purpose. A wrong one, but maybe they could do something about that without defeating it completely.
“To start with,” he said, “you can’t create any humans. That goes for all of you, in all of these labs. Is that clear?”
“Yes,” the robot replied. It looked at Derec, then back to the centrifuge. If it was disappointed, it didn’t show it.
“All right. Next, then, I need to know what those creatures” Derec waited until the robot looked to see where he was pointing, “-there at the end of the line-eat.”
“They are omnivorous,” the robot replied, gathering up a handful of empty tubes from a box and inserting them one by one into some sort of diagnostic instrument beside the centrifuge.
“There’s a whole bunch of them running loose in the city without a food supply. We need to give them one.”
“That would only increase their numbers. Is that what you wish to do?”
“No. But I don’t want them to starve, either.”
“We have discovered that if they do not starve, they will reproduce. There is no intermediate state. The number of creatures existing now are the result of a large food supply, which we have ceased providing.”
“You intend for them to starve, then?” Derec watched the robot push buttons on the face of the instrument.
“That is correct.”
“Why not introduce something that eats them?”
“That seems needlessly complex. Starvation will reduce their numbers equally well.”
“I see.” Derec felt somehow vindicated to hear the robot’s answer. Evidently robots didn’t make very good gods, either.
He thought of Avery’s suggestion to have the robots collect and kill them. A typical Avery idea, little better than the robots’ starvation plan. Much as he wanted to avoid conflict, Derec couldn’t let that happen, either.
“Look,” he said, going on into the lab and pulling up a stool, “even if you can’t make humans, this project of yours can still be good for something. Let me tell you about balanced ecosystems…”
The sun was long down by the time he made it home that night. Ariel was in the library, leaning back on a couch with her feet up on a stool and listening to one of Avery’s recordings of Earther music while she read a book. Neither Avery nor Wolruf were in evidence, though the loud snoring coming from down the hallway was suggestive of at least one of them. Mandelbrot stood in a wall niche behind Ariel, waiting for her to need his services.
Ariel put down the book and scowled at Derec in mock hostility when he entered the room. “Forget where you lived?” she asked.
“Almost.” Derec sat down beside her on the couch and nuzzled her neck playfully. “I’ve been trying to plan a simple ecosystem for the city, but it’s a lot tougher than I thought. Do you realize that you have to balance everything right down to the microbes in the soil? Pick the wrong ones, or not enough varieties of the right ones, and your whole biosphere goes crazy.”
“Is that so?”
“Yes, that’s so. I’ve been studying it all day.”
“Sounds exciting.” She yawned wide, and the book slipped from her fingers to land with a thump on the floor. “Oops. Tired.”
Derec scooped it up for her and laid it on the couch’s armrest. “It’s late. We should go to bed.”
“I guess we should.”
Derec took her hand and helped her up from the couch. She let him lead her into the bedroom, where he pulled down the covers and left her on the foot of the bed to undress and crawl in while he used the Personal.
When he came out, she was already asleep. He slid quietly into bed beside her and within minutes he was out as well, dreaming of food chains and energy flow.
But once again, he awoke to the sound of someone throwing up in the Personal. He sat up with a start, his heart suddenly pounding. The sun barely reached the window this time, but it was up. It was morning, and Ariel was sick.
His heart was still pounding when she opened the door and looked out at him. “Does this mean what I think it means?” he asked.
“I don’t know,” she said. “But I think we’d better find out.”
The urine test came up positive, as they knew it would. Even so, it was hard for either of them to remain standing when the medical robot said, “May I be the first to offer you congratulations on the occasion of-”
“Wow,” Derec murmured. He and Ariel had been holding hands in anticipation; now he squeezed hers tightly.
“Oh,” Ariel said, her hand suddenly going slack. “I don’t-”
“But how?”
“I wasn’t supposed to be able to-”
“The cure!” Derec wrapped his arms around her and picked her up off the ground in a hug. “When they cured your amnemonic plague on Earth, they must have ‘cured’ your birth control, too.”
“They might have warned me.”
Derec’s grin faltered. He set her back on her feet again.
“What’s the matter? Don’t you want-?”
Ariel took the two steps necessary to reach a chair and sat heavily. “I don’t know,” she said. “It’s just such a shock. I’m not ready for it.”
“Well, we’ve got plenty of time to get used to the idea. At least, I think we do.” Derec turned to the medical robot. “How far along is she?”
“Fifteen days, plus or minus a day,” answered the robot. “A blood test would be more accurate, but I discourage invasive testing for such minor gain.”
“Me too,” Ariel said. She held out her hand and Derec took it again. “Well. Two weeks. That leaves us a while yet.” She looked down the corridor into the empty expanse of the hospital, then back to Derec.
Derec squeezed her hand again for reassurance. He wouldn’t say he knew just how she felt, because he wasn’t the one whose body would swell with the developing baby, and he wasn’t the one who would have to go through the painful process of giving birth, but he did at least share the sudden confusion of learning that he was going to be a parent. Did he want to be a father? He didn’t know. It was too soon to be asking that sort of question, and at the same time, far, far too late. He was going to be one whether he wanted to be or not.
Well, it wasn’t like he couldn’t provide for a child. He had an entire city at his disposal, and more scattered throughout the galaxy, all full of robots who were hungry for the chance to serve a human. He certainly didn’t have to worry about food or housing or education. Childhood companions might be a problem, though, unless they could bring some more families to Robot City. Derec wondered if Avery would stand for it. If not, then Derec could build his own city. It wouldn’t take much; a few seed robots and a few weeks’ time. Or there was still their house on Aurora, come to think of it. Derec and Ariel had both grown up on Aurora; perhaps their child should as well.
All those thoughts and more rushed through Derec’s mind as he held Ariel’s hand in the hospital waiting room. He grinned when he realized how quickly he had begun planning for the baby’s future. It was an instinctive response; hormones that had been around since before humanity learned to use fire were directing his thoughts now. Well, he didn’t mind having a little help form his instincts. In this situation, it was about all he had to go on.
