There is no need to go into detail as to Camilla's bout with Mentor. Her mind, like Karen's, had had to mature of itself before any treatment could be really effective; but once mature, she took as much in one session as Kathryn had taken in all her many. She had not suggested that the Rigellian accompany her to Arisia; they both knew that he had already received all that he could take. Upon her return she greeted him as casually as though she had been gone only a matter of hours. "What Mentor did to me, Uncle Trig, shouldn't have been done to a Delgonian catlat. It doesn't show too much, though, I hope--does it?" "Not at all." He scanned her narrowly, both physically and mentally. "I can perceive no change in detail. In general, however, you have changed. You have developed." "Yes, more than I would have believed possible. I can't do much with my present very poor transcription of that thought, since the all-important fine detail is missing. We'll have to intercept another one. I'll get it _all_, this time, and it will tell us a lot." "But you did something with this one, I am sure. There must have been some developable features--a sort of latent-image effect?" "A little. Practically infinitesimal compared to what was really there. Physically, his classification to four places is TUUV; quite a bit like the Nevians, you notice. His home planet is big, and practically covered with liquid. No real cities, just groups of half-submerged, temporary structures. Mentality very high, but we knew that already. Normally, he thinks upon a very short wave, so short that he was then working at the very bottom of his range. His sun is a fairly hot main-sequence-star, of spectral class somewhere around F, and it's probably more or less variable, because there was quite a distinct implication of change. But that's normal enough, isn't it?" Within the limits imposed by the amount and kind of data available, Camilla's observations and analyses had been perfect, her reconstruction flawless. She did not then have any idea, however, that "X" was in fact a spring-form Plooran. More, she did not even know that such a planet as Ploor existed, except for Mentor's one mention of it. "Of course. Peoples of planets of variable suns think that such suns are the only kind fit to have planets. You cannot reconstruct the nature of the change?" "No. Worse, I can't find even a hint of where his planet is in space--but then, I probably couldn't, anyway, even with a whole, fresh thought to study."
