Ron hesitated, and then extended the butt towards the Scholar. He took it with a slight bow, weighed it in his palm, and then slipped the weapon into his pocket. "You did wisely," the doctor said, with noticeable relief. "If you had turned that gun on us, Scholar, I would have killed you on the spot." He patted the metallic bulk beneath his own coat. "I came prepared, too...." * * * * * The copter rose serenely towards the heavenly vault. Ron's small body was feeling the effects of the day's strain. It collapsed against the leathery cushions, the short arms and legs limp and dangling. The doctor patted his knee. "Another few moments," he said. "Where are we going?" "To the spaceport in Winnipeg. I have a friend there. He has two children of his own, both born in the Mars Colony. He'll be returning there within the week." "And you want me to go with him?" "Yes, Ron. I want you to grow up all over again, and then return to Earth. It won't be easy for you, but there will be advantages. Your life span has been lengthened. And right now, you know, you're something of a prodigy yourself." He chuckled dryly. "And what happens here?" Ron said bitterly. "What kind of Earth will I find on my return?" "An older Earth. Perhaps a wiser Earth...." "No, doctor." Ron forced himself to a sitting position. "Not with the Scholar alive and thriving, growing stronger and more intelligent with every passing year. It'll be _his_ Earth when I return...." The doctor stared at the night sky before answering. "No, Ron. He'll never live to see it. I knew that when I selected _your_ body to house his mind...." "What do you mean?" "I chose you for a reason, Ron. A vital reason. When you came to my office on your return from Andromeda, I discovered something about you which made up my mind. An ailment without a name or a symptom, found only rarely in the bodies of a few space travelers. You had it, Ron, and in a year or two, it would have struck you down with the savagery and surprise of lightning. "It was then that I agreed to the Scholar's plan to exchange bodies. Agreed to it on my own terms, with the body of Ron Carver...." "Then I'll die!" Ron said. "No, Ron. You will live. It's the Scholar who has made the bad bargain...." In the distance, the lights of the Winnipeg spaceport blinked a welcome.
