"Have you forgotten we can't get out of this place?" he reminded. "We can't get at either the marsuits or the groundcars." It was Dark's turn to smile. "I believe you said there aren't any guards on the airlocks to stop one from walking out at night?" he said. "That's true, but--" "There's something you don't know," continued Dark. "You were wondering at the basis of the regenerative power that permitted me to revive here after being shot in the stomach with a heatgun. I don't know what it is, but whatever it is, it's something that also permits me to live without oxygen. "Happy can testify that I was fully alive and conscious underwater. I discovered, before I was shot, that I can operate just as well outside, in the Martian atmosphere, without a helmet. And that's why Goat's records may solve our problem. "So tonight I'll leave this place and go to Ultra Vires. If there are any marsuits and groundcars left there, I'll come back here with them, and you and Happy and Shadow can escape with me. If not, you may have to wait a while longer. "But I'll be back!" 13 Brute Hennessey plodded westward through the Xanthe Desert, naked, wearing no marsuit, his head bare to the thin, oxygen-poor Martian air. The two small moons shone in the star-spangled sky above the lone figure, casting fantastic shadows on the sands. But this was not the stupid, shambling Brute Hennessey of a few months past. He walked surely and proudly, and the light of intelligence shone in his eyes. He called himself, now, Dark Kensington. Dark's muscular body had not regained, quite, the firmness and tone it had had before he was shot down at Solis Lacus, but he had recovered greatly from the bloated flabbiness of a few days ago. Most of that had been water in his tissues, and resumption of normal physical activity had wrung it out in short order. As he plodded through the Martian night toward Ultra Vires, Dark was remembering, with something of awe, that emotional explosion within him that had occurred on his first sight of Goat Hennessey at the Canfell Hydroponic Farm. It was this sudden, overwhelming recognition that had wrung from his lips the cry: "_Father!_" In that moment, memory had returned with terrible impact and he had been overwhelmed by the re-experience of those moments when he had stood before the man he admired and loved as his father and had seen the bitter realization of rejection by that man written with the point of a knife. Now he remembered it all. He remembered his childhood at Ultra Vires, he remembered Adam and their experiences together, he remembered their treks through the desert at Goat Hennessey's command, he remembered his slaying of Adam and his acceptance of death at Goat's hands. He remembered that he, Dark Kensington, was Brute Hennessey, somehow brought to life once before in the Icaria Desert even as he had himself regained life a second time in the vats of the Canfell Hydroponic Farm.
