“It wasn’t the act itself, but the betrayal.”

“Which you can’t bring yourself to forgive. Not even after all you did to him, and all the forgiving he had to do.”

Avery gulped down the rest of his water. He had no answer for her. He was thinking of all the times in the last few weeks he had tried to open up to Derec, tried to make up for his earlier failings as a father. At the time it had seemed the most difficult thing he’d ever done, which was why the sudden discovery of Derec ‘ s subterfuge had affected him the way it had.

Janet got up off her stool and stood beside the bed, looking down on him with angry eyes. “I wouldn’t come back to you even if you’d have me. Why do you think I left you in the first place? Because you could never forgive anything, that’s why. The least little mistake and you’d be sore for a week, and Frost help me if I made a big one. Is it any wonder I learned to prefer the company of robots?” She turned away and stalked to the window separating the recovery room from the rest of the hospital. Beyond it, Derec and Ariel were discussing something with the medical robot. Janet said, “You’ve learned to admit to your own mistakes; isn’t it time you learned to forgive other people for theirs?”

“Is that what you want from me, then? You want me to forgive our son for his…mistake?”

Janet turned back to face him. “That’s right, I want you to forgive him. I don’t think he even made a mistake, but that’s beside the point. The practice will do you good, because when you’re done forgiving David, then I want you to forgive Lucius for what he did, too.”

Avery looked for signs of a joke, but she seemed to be serious. He snorted. “You don’t ‘forgive’ robots. You melt them down and start over. Which is what I should have done with your three the moment I found them. “

“You’d have been committing murder if you had. In fact, according to David, you almost did just that. If he hadn’t revived them, you’d have been guilty of that, too.”

“Janet, I think you’ve been away from human companionship a little too long. They’re robots.”

“They’ve got intelligent, inquisitive minds. They feel emotion. You know what was going on in Lucius’s mind when he saw you again? He was mad. Furious, to hear Adam tell it. Does that sound like a robot to you?”

Avery waved his free arm. “Oh, they’re accomplished mimics, granted. You did a wonderful job with them in that regard. But there’s no way they can be anything but robots. They’ve got positronic brains, for God’s sake. It’s like-” He searched for an example as unlikely as a robot becoming human. “Ah, it’ s like Derec ‘ s precious ecosystem just over our heads. Most of the trees are robots. They do just about everything a tree can do, including feeding the birds, but could you seriously suggest that any of them really are trees? Nonsense. They’re robots, just like your ‘learning machines.’ “

Janet sat back down on the stool and took the empty glass from Avery. “I think we’re arguing semantics here. My robots may not be human in the most technical sense, but in every way that counts, they are. They’re every bit as human as any of the aliens you’ve met, and you’ve granted human status to most of those.”

“Reluctantly,” Avery growled. He remembered an earlier thought and asked, “Was that what you were attempting to do? Create your own aliens?”

“I was trying to create a true intelligence of any sort. Alien, human, I didn’t care. I just wanted to see what I’d get.”

“And you think you’ve got both.” Avery didn’t make it a question. He ran a hand through his hair, then let out a long sigh. “I don’t care. I’m tired. Call them what you want if it’ll please you, but keep ‘em away from me. As soon as this heals”-he nodded toward his right arm-”I’m leaving anyway, and you can do whatever you please.”

Janet shook her head. “No, you’re not going anywhere until we agree on a lot more than just my learning machines. I don’t much like your cities, either.”

“Fat lot you can do about that,” Avery said.

Janet smiled sweetly, but her words were a dagger of ice. “Oh, well, as a matter of fact, there is. You see, I patented the entire concept, from the dianite cell all the way up, in my name.”

Chapter 8. The Other Shoe Drops

The apartment was empty when Wolruf arrived. She padded softly through the living room, noting Ariel’s book reader lying on the end table by her chair and the empty niche where Mandelbrot usually stood, then went into Derec’s study and saw the bed there, still rumpled from sleep. The computer terminal was still on. She saw no cup in evidence, but the air conditioner hadn’t quite removed the smell of spilled coffee.

“W’ere is everybody?” she asked of the room.

“Derec and Ariel’s location is restricted,” Central replied.

Oh, great. Now they’d all disappeared. Unless… “ Are they at the same restricted location as before?” she asked.

“That is correct.”

Wolruf laughed aloud. She was learning how to deal with these pseudo-intelligences. She stopped in her own room just long enough to freshen up, then left the apartment and caught the slidewalk.

She found not only Derec and Ariel in the robotics lab, but an unfamiliar woman who had to be Derec’s mother as well. Derec was busy with the humaniform robot Wolruf had attempted to catch the last time she’d been near here. He was trying to remove the stump of its severed arm, and by his expression not having much success at it. Ariel was holding a light for him and Derec’s mother was offering advice.

“Try reaching inside and feeling for it,” she said.

Derec obediently reached in through the access hatch in the robot’s chest, felt around inside for something, and jerked his hand out again in a hurry. “Ouch! There’s still live voltage in there!”

“Not enough to hurt you,” his mother said patiently. “Not when he’s switched into standby mode like this. Would you like me to do it?”

“No, I’ll get it.” Derec reached inside again, but stopped when he heard Wolruf’s laugh. He looked up and saw her in the doorway.

“‘Ello.”

“Hi.” Grinning, Derec withdrew his hand from the robot and used it to gesture. “Mom, this is my friend Wolruf. Wolruf, this my mother, Janet Anastasi.”

“Pleased to meet you,” Wolruf said, stepping forward and holding out a hand.

Janet looked anything but pleased to be so suddenly confronted with an alien, but she swallowed gamely and took the proffered appendage. “Likewise,” she said.

Wolruf gave her hand a squeeze and let go. Looking over Janet’s shoulder, she noticed a huddle of four robots in the far corner of the lab: three learning machines and Mandelbrot. They looked to be in communications fugue. Nodding toward them, she said, “I ‘eard Lucius ‘urt Avery some’ow.”

“That’s right,” Ariel said. “He was trying to protect Basalom, here. We’ve got him in psychotherapy, if you can call four robots in an argument psychotherapy. They’re trying to convince him it’s all right.”

“It is?” Wolruf asked.

“Well, not the actual act,” Derec said, “but the logic he used wasn’t at fault. He just made a mistake, that’s all. He thought he was protecting a human.” Derec outlined the logic Lucius had used, including the First and Zeroth Law considerations that had finally made him do what he’d done.

Wolruf listened with growing concern. The Zeroth Law was just the thing she’d hoped for to reassure her that taking robots home with her wouldn’t destroy her homeworld’s society, but if that same law let a robot injure its master, then she didn’t see how it could be a good thing.

“I don’t know,” she said. “Sounds like a bad tradeoff to me.”

“How so?” Janet asked.

“I’m wondering ‘ow useful all this is going to be. Right now I’m not sure about regular robots, much less ones who think they’re ‘uman.”

“What aren’t you sure about?”

Was Derec’s mother just being polite, or did she really want to know? Wolruf wondered if this was the time to be getting into all this, to bring up the subject of her going home and to get. into all her reasons for hesitating, but she supposed there really wasn’t going to be a much better time. She knew what Derec and Ariel thought about the subject; maybe this Janet would have something new to say. “I’m not sure about taking any of these robots ‘ome with me,”
