question:  What is Peggy's importance to the mission?
context: The robots were built to serve Man; to do his work, see to his comforts, make smooth his way. At midday some few of the blue sun's rays filtered through to the jungle floor, but now, late afternoon on the planet, the shadows were long and gloomy. Then, through the trees he saw the clearing of the camp site, the temporary home for the scout ship and the eleven men who, with Alan, were the only humans on the jungle planet, Waiamea. Beyond, nose high, stood the silver scout ship that had brought the advance exploratory party of scientists and technicians to Waiamea three days before. But the back pressure of the cat's body overloaded the discharge circuits. If I can just hold out until morning, when the big ship arrives ... Good Lord, Peggy!" Peggy, arriving tomorrow with the other colonists, the wives and kids! A pretty girl, Peggy, the girl he'd married just three weeks ago. It was crazy, he supposed, to marry a girl and then take off for an unknown planet, with her to follow, to try to create a home in a jungle clearing. Crazy maybe, but Peggy and her green eyes that changed color with the light, with her soft brown hair, and her happy smile, had ended thirty years of loneliness and had, at last, given him a reason for living. The planet's double moon had risen and he could see a robot rolling slowly across the clearing in his general direction, blasting indiscriminately at whatever mind impulses came within its pickup range, birds, insects, anything. Six or seven others also left the camp headquarters area and headed for the jungle, each to a slightly different spot. Minutes later, looking back he saw that the machine, though several hundred yards away, had altered its course and was now headed directly for him.
