"These donors were dead, but you can be thankful we had parts of their mind in a sound body, but Dan Merrol had too much of one—and also too much of the other! "Sorry, darling," said Erica. She yawned, added, "I've tried—but I just can't believe you're my husband." sat up. "They said you were Dan Merrol at the hospital, but they must They hadn't—he'd read it on the chart. But he had been alone in the felt like Dan Merrol. "Your name is Erica." "They told you that too." She was wrong again, but it was probably wiser not to tell her how he knew. No one had said anything to him in the hospital. He hadn't given them a chance. He had awakened in a room and hadn't wanted to be alone. He'd got up and read the chart and searched dizzily through the closet. to himself. He'd sat down to gain strength and after a while he'd walked out and no one had stopped him. It was night when he left the hospital and the next thing he remembered "You may have known someone else with that name. When were we married?" Maybe he should have stayed in the hospital. It would have been easier to convince her there. But he'd been frantic to get home. "It was quite of him to have mentioned them. No woman approves her predecessors. "That's six. Where do I come in?" "Erica. You're the seventh and best." It was just too many, now that he thought of it, and it didn't seem right. She sighed and drew away. "That was a lucky guess on your age." "You did, though I'm sure you didn't mean to. I don't think you realized how strong you were. Dan was always too gentle—he must have been afraid of me. And He had been seriously injured and he was still weak from the shock. He memory? He leaned against the wall and nearly fell down. The length of that arm was unexpectedly different. He hobbled over to a chair and sat down, staring miserably at Erica as she began dressing. There was quite a contrast between the loveliness of her body and the circus comedy of his own. and all those wives too. Erica came close and leaned comfortingly against him, but he wasn't comforted. "I waited till I was sure. I didn't want to upset you." He wasn't as sure as she seemed to be now. Somehow, maybe he was still himself. Not after trying to sort out those damned memories. stretching the term, currently formed his body. It was clear what he had to do. The jacket he had worn last night didn't fit. Erica cut off the sleeve in it, he managed to expand it so it was not too tight. The trousers were also a problem—six inches short with no material to add on, but here again Erica proved equal to the task and, using the cuffs, contrived to lengthen them. Shoes were another difficulty. For one foot the size was not bad, but he could almost step out of the different . Erica gazed at him with melancholy affection. "I can't understand why they let you out wearing those clothes—or for that matter, why they let you out at all." He must have given some explanation as he'd stumbled through the door. It was the clothes, plus the brief glimpse of his face, which had made her think she recognized him when he came in. "They told me you'd have to have psychotherapy and I'd have to have It was then he'd grabbed her, to keep her from talking to the hospital. He'd been unnecessarily rough, but that could be ascribed to lack of coordination. She could have been terrified, might have resisted—but she hadn't. At that time, she must have half-believed he was Dan Merrol, still dangerously near the edges of post-regrowth shock. She was looking at him, waiting for that explanation. He shook his mind frantically and the words came out. "Self-therapy," he said briskly. "The patient alone understands what he needs." She started to interrupt, but he shook his head and went on blithely. "That's the first corollary of the theorem. The second is that there are critical times in the recovery of the patient. At such times, with the least possible supervision, he should be encouraged to make his own decisions initiative is more important than perfect health." "Strange," she muttered. "But you are very strong." She looked at him and blushed. "Initiative, certainly you have. Dan could use some, wherever he is." Dan again, whether it was himself or another person. For a brief time, as she listened to him, he'd had the silly idea that.... But it could never happen to him. He'd better leave now while she was distracted and skill. He wanted to protest, but didn't. Maybe it was the hand she was holding—it seemed to be equipped with a better set of nerves than its nodded and said nothing and she took it as he thought she would. "It wasn't anybody's fault. The warning devices which were supposed to were the pilot. They never let me see you until yesterday and then it was just a glimpse. I took their word when they said you were Dan felt he could manage a takeoff at this instant. But why hadn't he told her? Shock? Perhaps—but where had those other passionate, petite and wild, casual and complaisant, nagging and insecure? Erica he didn't remember at all, save from last night, and what was that due to? "What are you going to do?" he asked, deliberately toying with the last similar mistakes. Dan Merrol may be alive under another name. It will went to other hospitals, you know, the ones located nearest where they "Wysocki's theorem," he told her. "The patient has decided to walk." Last night, on an impulse, he'd left the hospital and now he had to go On his way in, he miscalculated, or she did, and he brushed against her. The touch was pleasant, but not thrilling. That reaction seemed reserved for Erica. "Glad to see you," said Doctor Crander, behind the desk. He was nervous and harassed for so early in the morning. "The receptionist didn't give She did at that, he thought—probably bewildered by his appearance. The hospital didn't seem to have a calming influence on either her or the It seemed wiser to Dan not to tell him everything. "It was stuffy inside. I went out for a stroll before the nurse came in." would have kept someone on duty through the night." They had underestimated him, but he didn't mind. Of course, he didn't The doctor took his pulse. "Seems fine," he said, surprised. "Sit down—please sit down." emotion at the moment—relief at the return of his patient. Miss Jerrems came back, wheeling a large cart. Dan was surprised at the certain. Taken altogether, the evidence was overwhelming. There had been no mistake—he was Dan Merrol, though it was not difficult to understand why Erica couldn't believe he was her husband. "You did a fine job," he said. Recalling the picture of the wreckage, he knew they had. "But couldn't you have done just a little better?" were one of the last to be extricated from the ship. Normally, when reasons. But the previously treated victims had depleted our supplies. Some needed only a hand and we gave them just that, others a hand and permit you to die—there wasn't time to send to other hospitals. In Merrol turned away miserably. There were other things, but he had learned the essentials. He was Dan Merrol and there was nothing they could do for him until it was too late. How long could he expect Erica to wait? The doctor hadn't finished the medical session. "Replacement of body Dan raised his head. Some things were clearer. The memories were authentic, but they weren't his—nor did the other wives belong to him. It was no wonder Erica had cringed at their names.
