 Why was the ugly man constantly chasing after Gabe?
When overwhelming danger is constantly present,of course a man is entitled to have a bodyguard. Everyone in the room was aware of the big young man, and most of the humans present were resentful, for he handled himself consciously and arrogantly, as if his appearance alone were enough to make him superior to anyone. Even the girl with him was growing restless, for she was accustomed to adulation herself, and next to Gabriel Lockard she was almost ordinary-looking. There was a short man standing next to the pair—young, as most men and women were in that time, thanks to the science which could stave off decay, though not death—but with no other apparent physical virtue, for plastic surgery had not fulfilled its bright promise of the twentieth century. "You must allow me to pay your cleaning bill," Gabe said, taking out his wallet and extracting several credit notes without seeming to look at them. And that, coming on top of Gabriel Lockard's spectacular appearance, was too much. The ugly man picked up the drink the bartender had just set before him and started to hurl it, glass and all, into Lockard's handsome face. Once the illuminators were extinguished in Gabriel Lockard's hotel suite, it seemed reasonably certain to the man in the gray suit, as he watched from the street, that his quarry would not go out again that night. There he inserted a coin in a locker, into which he put most of his personal possessions, reserving only a sum of money. After setting the locker to respond to the letter combination bodyguard , he went out into the street. As a matter of fact, no real identification was possible, for he was no one and had been no one for years. Each time it happens, there's a ... well, there's no experience to match it at a thrill-mill." Gabe Lockard was in no condition to drive the helicar. Fortunately the car was flying low, contrary to regulations, so that when they smashed into the beacon tower on the outskirts of the little town, they didn't have far to fall. To the girl's indignation, the stranger not only hauled Gabe out onto the dripping grass first, but stopped and deliberately examined the young man by the light of his minilume, almost as if she weren't there at all. Only when she started to struggle out by herself did he seem to remember her existence. He pulled her away from the wreck just a moment before the fuel tank exploded and the 'copter went up in flames.
 He wanted his body back.
 He was actually after Gabe's wife.  He wanted his body back.  He wanted some of Gabe's money.  He was only following him by coincidence.
