 Why did Davies attach himself to Infield outside of Infield & Morgan?
Henry Infield placed the insulated circlet on his head gently. The gleaming rod extended above his head about a foot, the wires from it leading down into his collar, along his spine and finally out his pants leg to a short metallic strap that dragged on the floor. Infield turned his soft blue eyes to the black and tan oxfords with the very thick rubber soles. Floating before him in memory was the vertical hoop and the horizontal hoop, both of shining steel-impervium alloy. The gyro actually passed over a man's shoulder, through his legs, under his arms. Any time he felt the walls creeping in to crush him, he could withdraw his head and limbs into the circle and feel safe. Or suppose he's walking down a railroad track and hears a train whistle—if he can hear anything over that verbal pablum gushing in his ear." With that image over everything he sees and with that insidious voice drumming in his head night and day, do you mean to say that man's senses will only be impaired 23 per cent? Infield stepped into the main stream of human traffic and tried to adjust to the second change in the air. Many "Cures" were not readily apparent. A young man with black glasses and a radar headset (a photophobe) was unable to keep from being pushed against Infield. It was the first time in years that anyone had apologized to Infield for anything. A clean-cut young man with mouse-colored hair was moving toward the stubble-chinned, heavy-shouldered man quivering in the center of a web of impervium cables stuck secure to the walls and windows of buildings facing the street, the sidewalk, a mailbox, the lamp post and Infield. Mouse-hair yelled hoarsely, "Uncouple it, Davies! The magnetic suction dart dropped away from Infield like a thing that had been alive and now was killed. After breathing deeply for a few moments, he looked up to see Davies releasing and drawing all his darts into his belt, making it resemble a Hydra-sized spiked dog collar. Mouse-hair stood by tensely as the crowd disassembled. Mouse-hair drove a fast, hard right into the soft blue flesh of Davies' chin. "Not—not long," Infield evaded. Infield's pulse raced, trying to get ahead of his thoughts, and losing out. The man's face paled so fast, Infield thought for an instant that he was going to faint. Infield shifted around, trying to see that side of his benefactor, but couldn't manage it in good grace.
 He was afraid of heights and falling over, so he had affixed himself to Infield in order to calm his fear.
 He was afraid of heights and falling over, so he had affixed himself to Infield in order to calm his fear.  He was attempting to catch Infield after he ran away from the fraternal club for the Cured.  He was afraid of the rain and lightning, and the cables helped him to feel more secure.  He had been aiming for George Price, whom he was trying to kill as punishment for knocking him to the ground earlier.
