"They said you were Dan Merrol at the hospital, but they must "Hospitals don't make that kind of mistake," he said with a certainty he didn't altogether feel. "But I should know, shouldn't I?" "Of course, but...." He did some verbal backstepping. "It was a bad accident. You've got to expect that I won't be quite the same at first." He sat up. " Look returned his gaze, then swayed toward him. He decided that she was "My name is Dan Merrol." like Dan Merrol. 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. 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?" He thought—and couldn't. He wasn't doing so well. "Another lapse," Did that mean he wasn't right on anything else? From the expression on her face, it did. "You've got to expect me to be confused in the realized how strong you were. Dan was always too gentle—he must have you weren't at all." leaned forward and caressed his cheek. "Everything seems wrong, no matter how hard I try to believe otherwise. You don't have the same personality—you can't remember anything." "And I have one brown eye and one green." the proportions differed from one side to the other. His knees didn't match. Be-dum, be-dum, be-dumdum, but your knees don't match —the What were they, a bunch of humorists? Did they, for comic effect, piece together a body out of bits and scraps left over from a chopping block? Dan Merrol—but he wasn't going to insist on it—not after looking at She was too kind, pretending to be a little attracted to him, to 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." for a day or so," she mused aloud. "It was the first time you'd been out of the regrowth tank—where no one could see you—and they didn't It was the clothes, plus the brief glimpse of his face, which had made her think she recognized him when he came in. 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 and carry them through by himself, even though running a slight risk of physical complications." "That's new, isn't it?" she said. "I always thought they watched the patient carefully." It ought to be new—he'd just invented it. "You know how rapidly medical practices change," he said quickly. "Anyway, when they examined me last night, I was much stronger than they expected—so, when I wanted to come home, they let me. It's their latest belief that 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, Dan again, whether it was himself or another person. For a brief time, is hungry in the morning." 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 accident —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. "It wasn't anybody's fault. The warning devices which were supposed to it was just a glimpse. I took their word when they said you were Dan passionate, petite and wild, casual and complaisant, nagging and insecure? that due to? "What are you going to do?" he asked, deliberately toying with the last bite of breakfast. It gave him time to think. "They said they'd identified everyone, living or dead, and I supposed they had. After seeing you, I can believe they made any number of "You'll have to put me down," she said, averting her eyes. "Otherwise.... You're an intolerable funny man." He knew it—he could see himself in the mirror. He was something to reconciled. He swept along, gaining control of his muscles. He became aware that he was whizzing past everyone. polite expression became a grimace of barely suppressed laughter. Then laughter was swept away. What replaced it he couldn't say, but it 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 He watched her appreciatively as she went inside. The way she walked, On his way in, he miscalculated, or she did, and he brushed against her. The touch was pleasant, but not thrilling. That reaction seemed 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 with vast relief. "For a while I had visions of...." He then decided that visions were nothing a medical man should place much faith in. "Then I Dan Merrol?" recognize you immediately." He exhaled peevishly. "Where did you go? It seemed wiser to Dan not to tell him everything. "It was stuffy would have kept someone on duty through the night." They had underestimated him, but he didn't mind. Of course, he didn't know how a patient from the regrowth tanks was supposed to act. The doctor took his pulse. "Seems fine," he said, surprised. "Sit down—please sit down." I'm Dan Merrol? Could there be a mistake?" before she could reel it in, her gaze swept past Dan, hesitated and returned to him. Her mouth opened and closed like that of a nervous goldfish and she darted from the room. They see me and flee as fast as they can caper , thought Merrol. It was not wholly true—Crander didn't seem much affected. But he was a doctor and used to it. Furthermore, he probably had room for only one emotion at the moment—relief at the return of his patient. body, excepting the blood, constitute proof more positive than fingerprints before the surgical exchange of limbs. Don't ask me why—no one knows. But it is true that cells differ from one body to the next, and this test detects the difference." The mass-cell radiographs did seem identical and Dr. Crander seemed Crander's eyebrows bounced up. "We're amazed at how well we have done. You can search case histories and find nothing comparable." His complaint...." "Nothing specific. But look at this hand...." doctor's diagnostic eye." The other just didn't understand. "But the size—it doesn't match my arm!" "Doesn't match ?" cried the doctor. "Do you have any idea of the does match? True, it may not be human organism, and we can hardly be striving for Botticelli bodies and Michelangelo men. First, your hand moves freely at the joint, a triumph Dr. Crander seemed about to pluck one of Dan's eyes from its socket. "Surgical and growth factors involved in splicing a massive nerve bundle pass any layman's comprehension. There are no non-technical terms to describe it." "Brain?" Dan was startled.
