THE CATERPILLARS QUESTION

But it took only a moment for Jack to conclude that he should keep his mouth shut, except for eating. This was his first direct evidence that the AI were fallible. There were things they didn't know. That was reassuring. It also argued for their legitimacy, in a perverse way. They were here to help Tappy, who didn't care about the fit of their clothing or the color of the food, so they didn't pay proper attention to that. They hadn't expec ed Jack, who could see and who knew, so were caught short. Malva would have put him under a mind-probe or something and gotten the details right even if it burned out his brain. The AI had left his mind alone. He had better encourage them to continue doing that.

Tappy was already eating. He dived into his meal, and the taste was close enough. Probably everything was made from hydroponic soybeans and with taste and color, but for all he could tell, the steak was from a dragon. It would do.

For dessert Abbie brought green pumpkin pie, and Brie brought cheese. Jack looked at her, and at the cheese, and stifled a laugh. It wasn't that the cheese was blue, literally; it was the coincidence of the name.

Tappy became aware of his reaction. Her face turned toward him.

"It's nothing," he said. "Just that I named her Brie, and Brie is a variety of cheese."

She smiled. Brie, the seeming woman, did not. She did not seem to be offended; she just did not have emotions, and would not have understood the humor anyway.

These were indeed robots. They And there was another key.

might be conscious, and know a lot, but they were not feeling. It seemed that it was not feasible for even this advanced civil'zation to duplicate a living creature to that extent.

They completed the meal, and the AI brought small hand-held units that blinked by their mouths, making them suddenly clean.

No toothbrushes needed here!

Now that he was fed, Jack realized how tired he was. It had been an extremely trying sequence of several days, physically and emotionally. The frenzied trek up the mountain in the night, the crossing through the portal, encounters with the honkers, big dome-ship of the Gaol, the capture and interrogation by Malva, the flight in the airplane, the struggle to get through the cloud, the nullification of volition-he realized that he had had no problem with that since Tappy had had him eat the paper with the symbol on it; he felt free-willed now. But tired.

"Maybe it's time to rest," he said. "If it's okay with you folk."

He suspected that they had a lot for Tappy to do, but he was sure she was as tired as he was.

Tappy nodded agreement, and that forestalled whatever the AI might have had in mind. "There are bedrooms," Abe said.

They got up, and Tappy managed to catch his hand. Her fingers clung to his, not letting go. She wanted him with her for what passed for night in this building.

Should he argue the case? On the one hand, he did not want to give the AI the notion that he regarded the Imago as a sex object, so it was better to sleep apart. On the other, he still didn't really trust this situation, and feared that once he separated from Tappy for any length of time, he might not be allowed to get together with her again. The AI could kick him out, and tell her that he had decided to go home. Then there would be no living person to watch out for her interests. Maybe the AI really wanted what was best for the Imago-but what of Tappy? There was a living, feeling girl there who was in some ways just like any other, but in other ways a truly tragic figure. Jack was no psychiatrist, but he honestly felt that in this situation, he was the only one who could truly relate to that girl.

So he went with her to the bedroom they had designated for her. The AI expressed no objection. Abe and Abbie came in to undress them.

"Uh-" Jack began. Then it occurred to him that he valued the things the AI did not know about him, and shouldn't give them away. They didn't know that human beings who chose to share a bedroom did not necessarily have strangers undress them. Let them remain ignorant.

So he let them do it. He was facing away from Tappy, and left it that way. In due course he and Tappy were in pajamas and nightie and in the bed, which was large enough for two. The AI withdrew through the doorway, which seemed to close behind them. The -ight faded, leaving them in darkness.

Tappy found his hand again and drew it to her. She wanted him closer.

Jack knew he had gone wrong once, but he wasn't going to do it again. Not this way. Tempting though the prospect might be, on one not-quite-secret level. If she was the Imago, she was probably beyond his aspirations. If she was a hurt blind girl, she was underage. Either way, forbidden.

"I am here to help you, Tappy," he murmured. "I think I can help you best just by being near you. Until you achieve your destiny." Then he drew his hand loose, rolled onto his stomach, and tried to sleep.

For a moment he was afraid she would start crying. Then she rolled over, too, toward him, and set her hand on his back. with that contact she seemed to be satisfied. Her breathing became even.

He was relieved. He knew that had she insisted on more, he would in the end have succumbed. He had before. It was not easy doing what he believed was right. But it was best. He could never fully redeem the wrong he had done her, there in the cabin in the Green Mountains of Vermont, so far away in more than one sense. Maybe his recent efforts to get her to wherever she was Meanwhile he could at least going represented his need to atone.

avoid making it worse.

He slept, and dreamed, and in one dream he was approaching Tappy, desiring her, and feeling guilty for it. He knew, even asleep, that she was beside him, and it was his duty to leave her alone. But there was that in him that wanted it otherwise.

He knew it was morning, because it was light, and Abe and Abbie were there to get them dressed. Jack felt greatly refreshed; maybe there was something restorative in slept well, and it seemed that Tappy had, to note that the two AI had gotten mixed tending to Jack, and Abe to Tappy. An evidently not of great significance to them.

They took turns in the shower, stripping managed to avoid looking at Tappy's nude body the night before, but realized that he could not do so now without making more of his human foibles apparent than he cared to. Fortunately he had a reflex that prevented him from having a masculine reaction in public. So he affected neutrality, as he had during the night.

Whatever the AI did not know about any aspect of his relationship with Tappy was fine by him.

Her body was and was not what he expected. She was slender, but not thin; her legs were nicely fleshed, her hips and buttocks rounding into womanhood, and her breasts were well enough formed. Yet neither was she at the adult level. He judged that she was about halfway across her transition from childhood to womanhood, physically. In some countries, as he understood it, a girl was considered to be old enough if she appeared old enough; mere years did not define statutory rape. In such a country, he would have been in trouble anyway.

But there was something else. That intangible glow. She turned her face to him and smiled, fathoming where he stood, and it was as if there were an aura about her. She knew what they had done, and she regretted it not at all. She had in that sense proven herself.

Perhaps it had been at that point that she became independent of the need for the leg brace. She had begun to assume command of the situation, to choose her own course. To lead. She had led him to the portal between worlds. The Imago had begun to manifest, and surely it permeated her now. She had power, and knew it, and her growing confidence manifested in a straighter stance, a certainty of acceptance, and a subtle knowing. In a country that judged by attitude, she would be deemed old enough.
