Jason Allison, Junior, was listed on the directory of the Terran HQ as "Suite 1214, Medical Residence Corridor." I found the rooms without any trouble, though an elderly doctor stared at me rather curiously as I barged along the quiet hallway. The suite--bedroom, minuscule sitting-room, compact bath--depressed me; clean, closed-in and neutral as the man who owned them, I rummaged them restlessly, trying to find some scrap of familiarity to indicate that I had lived here for the past eleven years. Jay Allison was thirty-four years old. I had given my age, without hesitation, as 22. There were no obvious blanks in my memory; from the moment Jay Allison had spoken of the trailmen, my past had rushed back and stood, complete to yesterday's supper (only had I eaten that supper twelve years ago)? I remembered my father, a lined silent man who had liked to fly solitary, taking photograph after photograph from his plane for the meticulous work of Mapping and Exploration. He'd liked to have me fly with him and I'd flown over virtually every inch of the planet. No one else had ever dared fly over the Hellers, except the big commercial spacecraft that kept to a safe altitude. I vaguely remembered the crash and the strange hands pulling me out of the wreckage and the weeks I'd spent, broken-bodied and delirious, gently tended by one of the red-eyed, twittering women of the trailmen. In all I had spent eight years in the Nest, which was not a nest at all but a vast sprawling city built in the branches of enormous trees. With the small and delicate humanoids who had been my playfellows, I had gathered the nuts and buds and trapped the small arboreal animals they used for food, taken my share at weaving clothing from the fibres of parasite plants cultivated on the stems, and in all those eight years I had set foot on the ground less than a dozen times, even though I had travelled for miles through the tree-roads high above the forest floor. Then the Old-One's painful decision that I was too alien for them, and the difficult and dangerous journey my trailmen foster-parents and foster-brothers had undertaken, to help me out of the Hellers and arrange for me to be taken to the Trade City. After two years of physically painful and mentally rebellious readjustment to daytime living, the owl-eyed trailmen saw best, and lived largely, by moonlight, I had found a niche for myself, and settled down. But all of the later years (after Jay Allison had taken over, I supposed, from a basic pattern of memory common to both of us) had vanished into the limbo of the subconscious.
