The broken, shredded end of a slender cigarette soared up from the ground and settled in Leyloon's hand. A stream of smoke formed in the air, and flowed into her mouth. She put the cigarette to her lips. It glowed. She smiled and chattered gaily, nonsensically. Little clouds of blue-gray smoke kept forming unnaturally in the open air and flowing into Leyloon's mouth and nostrils. The cigarette grew in length with each inhalation. Darrel stared. It was really incredible! When the cigarette was whole again, the girl put a flaring lighter to it, and the tip went out. She placed lighter and cigarette in her bag. "Whew!" said Darrel. "This is beginning to give me the creeps." He tried his best to grin. "What happens now, Leyloon? If my theory is right, we're going to back-track into your time." As if in answer to his question, Leyloon began to back off rapidly down the hill. "Whoa!" Darrel ran after her. He felt all kinds of a fool walking that way. They faced each other, about a foot apart, she striding backward like something out of last year's nightmare, and he striding forward following her. It was the damnedest sensation! He wondered how she felt about it. If his theory was correct, then Leyloon thought _she_ was following _him_ the way he was following her. To anyone watching, they must have looked like a pair of lunatics. Here they were, existing simultaneously on the same planet, Neptune, but existing in time-streams diametrically opposed. While Neptune and all things of and on it were moving in time toward their youth and beginnings, _he_ was moving in time toward maturity and death. But, paradoxically, each to himself was growing toward age in a normal manner. From either viewpoint, the other was growing or becoming younger with every minute. His yesterday was Leyloon's tomorrow, but Leyloon's yesterday was _his_ tomorrow. The situation seemed hopelessly absurd. Absurd or not, he would have to make the best of it. But it all seemed so senseless! Why in blazes was he going off on this wild-goose chase? Leyloon was backing up briskly, only a foot or so ahead of him. Maybe that was why. She was exquisite. It was a satisfaction to have her near, even though her world was all out of whack. And she was getting under his skin more and more every minute. A Neptunian nymph, possibly a figment of his erratic imagination, and he was falling for her. Like a meteor. He, Darrel Bond, cool, level-headed astronaut falling for a Neptunian myth with serene face and fouled-up metabolism! Yes. He was. He had to admit it. He followed Leyloon's tantalizing figure through the bewildering city. The swarm and rush of reverse traffic and activity made his head spin dizzily. Leyloon turned finally, into a house. The noises of the city were suddenly cut off. Almost immediately the business with paper and pen began. She picked a sheet from a desk and held it out to him. "It is almost evening," it read. "I will go back to the ship with you now."
