 What was it that ultimately converted Thig to being human?
He had blasted across trackless space to subdue a defenseless world—only to meet on Earth emotions that were more deadly than weapons. [Transcriber's Note: This etext was produced from Planet Stories Fall 1942. Thig was shorter than the average Earthman—although on Ortha he was well above the average in height—but his body was thick and powerfully muscled. Here he patiently sat down to wait for an Earthman or an Earthwoman to pass. His task now was to bring a native, intact if possible, back to the carefully buried space cruiser where his two fellows and himself would drain the creature's mentality of all its knowledge. In this way they could learn whether a planet was suited for colonization by later swarms of Orthans. "With a psychic relay we will transfer the Earthman's memories and meager store of knowledge to the brain of Thig! "For the good of the Horde," Thig intoned almost piously as he lifted Terry's body and headed for the laboratory. So it was that the bodies of the Earthman and the Orthan were strapped on two parallel tables of chill metal and the twin helmets, linked to one another by the intricacies of the psychic relay, put upon their heads. The shock upon the nervous system of the Earthman proved too violent and his heart faltered after a time and stopped completely. Twice, with subtle drugs they restored pseudo-life to his body and kept the electrical impulses throbbing from his tortured brain, but after the third suspension of life Thig removed his helmet.
 Love. Love for his new family, and the uncertainties of human life.
 Lewis Terry. Lewis's mind took over his completely.  Disease. It was as Torp suspected. Being on Earth affected him too deeply.  Comfort. Earth culture is not nearly as controlling as Orthan culture.  Love. Love for his new family, and the uncertainties of human life.
