<passage>:
"These donors were dead, but you can be thankful we had parts of their 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." He felt his own yawn slip off his face. "What do you mean? What am I doing here then?" "Can't you remember?" Her laughter tinkled as she pushed him away and sat up. "They said you were Dan Merrol at the hospital, but they must have been wrong." returned his gaze, then swayed toward him. He decided that she was highly attractive—but surely he ought to have known that long ago. ." "I wish you could." Her voice was low and sad and he couldn't guess why. "My name is Dan Merrol." "They told you that at the hospital." They hadn't—he'd read it on the chart. But he had been alone in the room and the name had to be his, and anyway he felt "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. Clothes were hanging there and he'd put them on and muttered her name chart nor her address and yet he had found her. That proved something, didn't it? "How could I forget you?" he demanded. "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 a smashup," he said. "You'll have to expect some lapses." "I'm making allowances. But can't you tell me something about myself?" of light. And the rest of the stuff will come back in time." It was easier now that he'd started and he went on rapidly. "I'm thirty-three and after making a lot of money wrestling, married six girls, not necessarily in this order—Lucille, Louise, Carolyn, Katherine, Shirley and Miriam." That was quite a few marriages—maybe it was thoughtless 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 duplicated since Man began? He felt the stubble on his face with his left hand—he thought it He hobbled over to a chair and sat down, staring miserably at Erica as "Difficult, isn't it?" she said, tugging her bra together and closing It was difficult and in addition to his physique there were the memories he couldn't account for. Come to think of it, he must have been awfully busy to have so many careers in such a short time— 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 Dan Merrol—but he wasn't going to insist on it—not after looking at himself. Not after trying to sort out those damned memories. She was too kind, pretending to be a little attracted to him, to the scrambled face, to the mismatched lumps and limbs and shapes that, The jacket he had worn last night didn't fit. Erica cut off the sleeve to add on, but here again Erica proved equal to the task and, using 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 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 because of the theorem. You said you'd explain it this morning." She 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 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 back," he told her. "Not before you eat," she said. "Any man who's spent the night with me It was a domestic miracle that amidst all the pressing and fitting, she'd somehow prepared breakfast and he hadn't noticed. It was a simple chore with the automatics, but to him it seemed a proof of her wifely skill. —and that was where he'd got the idea. There had been other marks too, but he hadn't been able to decipher them. He nodded and said nothing and she took it as he thought she would. 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 Dan Merrol was a spaceship pilot and he hadn't included it among his skills. It was strange that she had believed him at all. But now that felt he could manage a takeoff at this instant. But why hadn't he told her? Shock? Perhaps—but where had those other identities come from—lepidopterist, musician, actor, mathematician and wrestler? And where had he got memories of wives, slender and 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 went to other hospitals, you know, the ones located nearest where they fell." Even if he was sure, he didn't know whether he could tell her—and he wasn't sure any longer, although he had been. On the physical side of marriage, how could he ask her to share a body she'd have to laugh at? Later, he might tell her, if there was to be a 'later.' He pushed back his chair and looked at her uncertainly. astray and got tangled with his fingers. "I just thought of a joke," she murmured. "Please don't think that I consider you at all funny." The hell she didn't—and it was the second time within the hour a woman had used that word on him. He wished they'd stop. He took back his in the middle of a grave emergency." On his way in, he miscalculated, or she did, and he brushed against reserved for Erica. It seemed wiser to Dan not to tell him everything. "It was stuffy before she could reel it in, her gaze swept past Dan, hesitated and 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, complaint...." 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? mathematician, went into the places I tapped." 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.
