She was sensing as she never had before and never dreamed she could.

So, though she could now leave the rock, secure in the knowledge she was both alone and unobserved, she did not; partly out of amazement, partly out of the curious exultation she felt at understanding and her desire to experience it further.

Her sensitivity was such that she even knew why he was sensitive. Odeen had frequently remarked how well he understood something after a period of melting, even though he had not understood it at all before. There was something about the melted state that increased sensitivity incredibly; more was absorbed; more was used. It was because of the greater atomic density during melting, Odeen had said.

Even though Dua was not sure what “greater atomic density” meant, it came with melting and wasn’t this present situation rather like melting? Hadn’t Dua melted with rock?

When the triad melted, all the sensitivity went to Odeen’s benefit. The Rational absorbed it, gained understanding, and retained that understanding after separation. But now Dua was the only consciousness in the melt. It was herself and the rock. There was “greater atomic density” (surely?) with only herself to benefit.

(Was this why rock-rubbing was considered a perversion? Was this why Emotionals were warned off? Or was it just Dua because she was so rarefied? Or because she was a Left-Em?)

And then Dua stopped all speculation and just sensed—in fascination. She was only mechanically aware of Tritt returning, moving past her, passing in the direction back from which he had come. She was only mechanically aware—scarcely feeling the vaguest surprise—that Odeen, too, was coming up from the Hard-caverns. It was the Hard Ones she was sensing, only they, trying to make more out of her perceptions, trying to make the most out of them.

It was a long time before she detached and flowed out of the rock. And when that time came, she was not concerned overmuch as to whether she would be observed. She was confident enough of her sensing ability to know she wouldn’t be.

And she returned home deep in thought.

Odeen had returned home to find Tritt waiting for him, but Dua still hadn’t returned. Tritt did not seem disturbed at that. Or at least he seemed disturbed, but not at that. His emotions were strong enough so that Odeen could sense them clearly, but he let them go without proving. It was Dua’s absence that made Odeen restless; to the extent that he found himself annoyed at Tritt’s presence simply because Tritt was not Dua.

In this he surprised himself. He could not deny to himself that it was Tritt who, of the two, was the dearer to him. Ideally, all members of the triad were one, and any member should treat the other two exactly on a par—both with each other and with him (her) self. Yet Odeen had never met a triad in which this was so; least of all among those who loudly proclaimed their triad to be ideal in this respect. One of the three was always a little left out, and generally knew it, too.

It was rarely the Emotional, though. They supported each other cross-triad to an extent that Rationals and Parentals never did. The Rational had his teacher, the proverb went, and the Parental his children—but the Emotional had all the other Emotionals.

Emotionals compared notes and if one claimed neglect, or could be made to claim it, she was sent back with a thin patter of instructions to stand firm, to demand! And because melting depended so much on the Emotional and her attitude, she was usually pampered by both left and right.

But Dua was so non-Emotional an Emotional! She didn’t seem to care that Odeen and Tritt were so close, and she had no close friendships among the Emotionals to make her care. Of course that was it; she was so non-Emotional an Emotional.

Odeen loved having her so interested in his work; loved having her so concerned and so amazingly ready of comprehension; but that was an intellectual love, lie deeper feeling went to steady, stupid Tritt, who knew his place so well and who could offer so little other than exactly what counted—the security of assured routine.

But now Odeen felt petulant. He said, “Have you heard from Dua, Tritt?”

And Tritt did not answer directly. He said, “I am busy. I will see you later. I have been doing things.”

“Where are the children? Have you been gone, too? There is a been-gone feel to you.”

A note of annoyance made itself plain in Tritt’s voice.

“The children are well-trained. They know enough to place themselves in community-care. Really, Odeen, they are not babies.” But he did not deny the “been-gone” aura that he faintly exuded.

“I’m sorry. I’m just anxious to see Dua.”

“You should feel so more often,” Tritt said. “You always tell me to leave her alone. You look for her.” And he went on into the deeper recesses of the home cavern.

Odeen looked after his right-ling with some surprise. At almost any other occasion he would have followed in an attempt to probe the unusual uneasiness that was making itself quite evident through the ingrained stolidity of a Parental. What had Tritt done?

—But he was waiting for Dua, and growing more anxious by the moment, and he let Tritt go.

Anxiety keened Odeen’s sensitivity. There was almost a perverse pride among Rationals in their relative poverty of perception. Such perception wasn’t a thing of the mind; it was most characteristic of Emotionals. Odeen was a Rational of Rationals, proud of reasoning rather than feeling, yet now he flung out the imperfect net of his emotional perception as far as he could; and wished, for just a moment, that he were an Emotional so that he could send it out farther and better.

Yet it eventually served his purpose. He could detect Dua’s approach, finally, at an unusual distance—for him —and he hastened out to meet her. And because he made her out at such a distance, he was more aware of her rarefaction than he ordinarily was. She was a delicate mist, no more.

—Tritt was right, Odeen thought with sudden, sharp concern. Dua must be made to eat and to melt. Her interest in life must be increased.

He was so intent on the necessity of this that when she flung herself flowingly toward him and virtually engulfed him, in utter disregard of the fact that they were not in private and might be observed, and said, “Odeen, I must know—I must know so much—” he accepted it as the completion of his own thought and did not even consider it strange.

Carefully, he slipped away, trying to adopt a more seemly union without making it seem he was repulsing her. “Come,” he said, “I’ve been waiting for you. Tell me what you want to know. I will explain all I can.”

They were moving quickly homeward now, with Odeen adapting himself eagerly to the characteristic waver of the Emotional flow.

Dua said, “Tell me about the other Universe. Why are they different? How are they different? Tell me all about it.”

It did not occur to Dua she was asking too much. It did occur to Odeen. He felt rich with an astonishing quantity of knowledge and was on the point of asking, How do you come to know enough about the other Universe to grow so curious about it?

He repressed the question. Dua was coming from the direction of the Hard-caverns. Perhaps Losten had been talking to her, suspecting that despite everything Odeen would be too proud of his status to help his mid-ling.

Not so, thought Odeen gravely. And he would not ask. He would just explain.

Tritt bustled about them when they returned home. “If you two are going to talk, go into Dua’s chamber. I will be busy out here. I must see to it that the children are cleaned and exercised. No time for melting now. No melting.”

Neither Odeen nor Dua had any thought of melting, but there was no thought in either mind of disobeying the command. The Parental’s home was his castle. The Rational had his Hard-caverns below and the Emotional her meeting places above. The Parental had only his home.
