“And,” said O’Mara.
“Currently it carries four Educator tapes,” said the lieutenant, “Tralthan, Melfan, Dwerlan, and Earth-human. I checked the donors’ psych profiles and none of them seemed as if they would be particularly hard to live with, especially for a strong-willed Kelgian like Yursedth who has years of experience with mind transfers. Its own psych file shows nothing suspect in its past. As for the troublesome dreams, which are causing mental distress of nightmare proportions during sleep and continual worry for hours subsequent to waking, I can find no cause for them. The same applies to the bouts of peripheral neuropathy, which are almost certainly associated with the main problem because they so closely resemble the nightmares. If there is a culprit tape, as you called it, I couldn’t identify it. This is a strange one, sir, because there is no obvious reason why the subject’s problem should exist.”
O’Mara nodded. “You didn’t expect me to hand you an easy one, Lieutenant,” he said. “What are you doing about this nonexistent problem?”
“The subject is becoming increasingly distressed,” said Braithwaite, “and I don’t want to waste time duplicating someone else’s work, especially yours. Yursedth wouldn’t tell me, at the time it was still annoyed because it wasn’t being treated by you, whether you had already initiated any kind of therapy. Have you?”
O’Mara shook his head. “I barely glanced through Yursedth’s file to check on its current workload,” he said, “which was about normal for a diagnostician of its seniority. The original question stands, Lieutenant: what are you going to do?”
Braithwaite was silent for a moment, and then he said, “I already checked for stress due to overwork and found nothing unusual. I’m going to get it to talk about its dreams and psychosomatic episodes again, and listen even more carefully this time. If nothing else occurs to me, I’ll suggest erasing the Melfan tape. If any of the Educator tapes are causing the trouble it is likely, well, slightly more likely, to be that one. As you know, sir, while the Melfans have very precise and accurate muscle control and positional sense, but the exoskeletal structures covering their limbs and digits have no sense of touch. It is probably a forlorn hope, but that might equate with Yursedth’s waking loss of sensation in its limbs and other areas of its body and its persistent nightmares. One of them, the one that seems to trouble it most, is about it being in a hospital OR on Melf and unable to operate because of an unexplained, creeping paralysis. I would then erase the Melfan tape and, before impressing another, observe and question the subject closely for a few days or weeks, to see whether or not the troublesome symptoms were still present or receding. I would do the same with the other tapes in turn and, if that didn’t work, I’d erase all of them and observe the effects. If any.”
O’Mara sat back in his chair and kept his face expressionless. Everyone on the staff knew that Yursedth had teaching duties as well as ongoing surgical commitments using its own medical experience as well as that of its four other-species mind partners. Time, as well as considerable personal mental disruption, was required to acclimatize mentally after the erasure of long-term tapes, which was why junior medics were not allowed to retain them for more than a few hours after use. Much more time and considerable emotional hassle would be needed for Yursedth’s mind, which subjectively would feel suddenly empty, to accommodate the alien knowledge and feelings of four new mind partners. But Braithwaite knew all this.
Deliberately, O’Mara decided to give a noncommittal, unhelpful answer. He said, “I can only imagine what Yursedth will say about that.”
“I didn’t have to imagine,” said Braithwaite feelingly. “It told me what it thought in detail when I told it what I intended to do, purely as a last resort. I hoped that would concentrate, well, scare its mind to the extent of producing a reaction that would furnish a clue to the basic problem. It didn’t. Apart from the verbal abuse it said that it would ask for a second opinion. Yours.”
