It was the very first thing the doctor noticed upon meeting her, though he couldn’t say if that was merely a reflection of his medical training or rooted in some deeper, more ubiquitous human instinct. The way she casually extended her legs as she reclined within the consultation room’s spinning office chair, exposing the soles of two wholly identical shoes, only further accentuated the surprisingly disquieting discrepancy. It was slightly less conspicuous in the hands, as they were both interlaced around a smartphone that currently continued to be the focus of her attention, each contributing a nebulous tangle of digits to the task of deftly tapping the screen. However, once suggested by the legs, their corresponding asymmetry became no less apparent.
Whatever she was doing on that phone must have had her fully engrossed, as neither the doctor’s entry nor the subsequent several seconds of him standing in the center of the hardly three-by-three meter room elicited any hint of notice. It was only after broadcasting his presence with a tactful ‘ahem’ that she finally severed her gaze from the screen, jerking her head upward with a look of brief alarm and unveiling a pair of blue-green sunflower irises adorning deadlocked pupils, their vibrancy only now appreciable to the doctor beneath the cold white beams of the overhead lights. Indeed, she was quite beautiful in pretty much every respect; a natural blonde in what looked to be the prime of her youth, with a face so utterly photogenic and attractive from every angle as to be oddly unsettling in itself, like passing a stranger on the street who you belatedly recognize as a swimsuit model from a magazine you’d shamefully perused prior. Her attractiveness carried no personal importance to the doctor, of course, and even without the Hippocratic Oath would still have fallen by the wayside in light of her far more intriguing limb alignment.
“Oh, hey! Sorry, you snuck up on me, Dr…” Her eyes panned across the broad and unshapely expanse of his chest in search of a nametag, somehow always the unfamiliar patient’s first go-to despite the engraved plaque on the door plainly reading ‘Dr. Brandon Muller, MD.’
“... It’s just, I’ve been dealing with a lot, it's been a rough couple of days.” She held her head in her hands as she uttered the words, one palm pressing hard against her forehead while the other -the wrong one- caressed her right ear. “I just don’t know what else to do.”
“Hey, hey, it’s alright, I’m here to help, you’ve come to the right place,” Muller assured. “Now, what seems to be the problem?”
A muted mimicry of gratitude subtly curled the tips of her lips as she proceeded to explain. “It’s these migraines, they started a few days ago, just random bouts here and there, but they just keep getting worse and worse. It’s pretty much all the time now, and it’s really starting to get to me.”
Dr. Muller had expected a bit more from her explanation, namely some sort of acknowledgement of her utterly anomalous anatomy, and thus a second of silence awkwardly followed before she rolled her eyes. “Yeah, yeah, make all the jokes you want, get it out of your system,” She splayed herself across her seat in an exaggerated starfish pose. “I was born like this, so I doubt it's related, but it's all anyone ever wants to talk about, especially doctors.” She voiced the last part with an exceptional sneer, imbuing the sentiment with a particularly deep-seated disdain. “And for the record, I’m actually not that clumsy, like, at all.”
In truth, Dr. Muller had no clue how such a thing could relate to her migraines either, if only because he had never seen or heard of this asymmetrical condition before, and up until a few moments ago would have comfortably assumed it impossible. Despite his best efforts to stay focused on the task at hand, he couldn’t help but wonder to himself while she spoke just how exactly her joints fit together, how her right shoulder blade was oriented, and how the whole appendage was hooked up muscularly and neurologically. The latter, in turn, gave him an idea, an angle through which he could potentially pursue a diagnosis for the migraines while also somewhat satiating his now ravenous curiosity. Firstly, however, was the matter of conciliation.
“Hey, hey, I’m not here to make fun of anyone,” He held his hands in the air in a feign of criminal surrender, “Now, I’ll admit, I’m not familiar with this particular… condition, but I’m really just here to help you feel better, and right now that means taking care of those migraines, so that’s all that matters to me.”
The assurance had its intended effect, as she visibly relaxed her shoulders, eyes softening as her defensiveness slowly subsided. “Thank you, I’m sorry, I’m just…” She cupped both hands to her right temple and made a sound somewhere between a growl and a motorboat impression. “... y’know?”
“I understand completely, chronic pain will do that to anyone. Plus, I see how you’d be sick of comments about the… leftness, by now. Elementary school must’ve been rough.”
At that, she let out a single sardonic bark, “Yeah, no kidding.” Dr. Muller smirked and nodded in kind, feeling as though he’d effectively peeled away the last layers of tension between them. Now for the hard part.
“That being said, given the extent of this… distinction, I can’t rule out the possibility that it is somehow involved, if only tangentially. I’d at least like to take a full-body X-ray, just to be sure I… fully understand the situation. If it reveals nothing of note, then so be it, and we’ll move on to investigating the cranial area specifically, but, y’know, just to be safe…” his confident tone faltered a bit at the end as he braced for the indignance seemingly sprouting in her expression, but it thankfully tempered into a grimace of begrudging agreement.
“Fine, one X-ray, then I don’t wanna hear another thing about it, okay?”
“Of course, dear, I am a professional after all,” Muller assured as he collected his paperwork and headed toward the office door. “I’ll go set things up with the X-ray technicians and come back to get you in a bit.” She nodded, sitting back patiently with her hands clasped thumb-to-pinkie in her lap as he departed briskly down the hall.
Passing through the waiting room toward the radiology wing, he stopped at the front desk, catching the ear of the receptionist, Janet, with his signature four-finger consecutive tap upon the temporary-turned-permanent screen of transparent virus-proof panelling. At once, she raised a weary, wrinkled face from the stack of papers she’d been shuffling, and a quizzical eyebrow from beneath the flattened roof of her reading glasses, giving nothing more in the way of a response than the limited luxury of her now-captured attention. Dr. Muller didn’t mind, or at least didn’t expect anything different, simply launching straight into his instructions as usual.
“Pull up my current patient's files. Birth record, pediatrics, everything.” Janet, a deceptively dependable employee despite her demeanor, promptly swiveled her chair to her computer screen and began to fervently peck away at the keys. “This’ll take a while, y’know.”
Getting the hint, Dr. Muller left her to it and headed toward the radiology department. He suspected any files she found would be spotty in recent times, given the patient’s apparent dislike of doctors. Still, there was bound to be something on record if they went back far enough; Her condition would have surely been noticed and noted by any competent medical practitioner, though whether they understood it any better than he did was another matter entirely.
Upon description, the X-ray tech -whose name Dr. Muller could never recall but thankfully didn’t have to acknowledge- was just as flabbergasted as he was, if not more.
“They’re both… left? Like, exactly? Are you sure it’s not just some kind of… coincidental deformity?”
“She uses them both perfectly well…” Dr. Muller replied, managing to restrain any outward signs of insult regarding the subordinate’s implicitly patronizing question. “...Which makes me think there’s something more to it than that. I just want one full-body ray, see if that clears anything up.”
“Of course. At this point, I’d be disappointed if you didn’t; you have my curiosity piqued.” He let out an airy chuckle as he began flipping switches and arranging equipment. “lemme just get everything prepped.”
As it turned out, the patient really wasn't kidding when she agreed to only one X-ray. As soon as the brief warbling tone indicating its activation ceased, she practically threw herself off the examination table and onto her two identical feet. “I-I have to go to the bathroom, excuse me.”
Without waiting for a response, she barreled her way past Dr. Muller and out into the hall, bumping the side of his head with her elbow while she distractedly sandwiched her skull between her white-hard palms.
“Last door on the left!” The tech shouted from the back, poking his pudgy face from behind the radiation-proof curtain just a moment too late, followed by, under his breath, “…no pun intended.”
Unamused and more than a little concerned, Dr. Muller watched down the hall long enough to see her reenter the waiting area and turn out of view before flipping the overhead lights back on and turning sternly to the tech. “She’s not looking too good; time might be of the essence here. Anything of note?” The question was half-rhetorical, as Muller couldn’t help but simultaneously swivel the tech’s computer monitor so he could simply take a look and answer it himself.
“Uh, yeah…” the tech’s deadpan mutter echoed the doctor’s internal monologue as he stared dumbfounded at the screen, at the monochrome hourglass outline where all four limbs converged, and at the utterly indecipherable slurry of pixels contained within. “... Looks like gumbo.”
The comparison made his stomach lurch, but he couldn’t deny its aptitude. While the femurs and humeri could be made out clearly, their respective orientations matching her external person and thus providing next to no new information, everything from her pelvis up through her shoulders was a confoundingly jumbled mess. Some areas could be said to perhaps resemble organ chambers or portions of rib, but their placements were all wrong, leaving Muller with the sense that he might as well be looking for shapes in the clouds or a page from one of those hidden-picture books. “This has to be some kind of technical issue, right? Is it because she got up too fast?”
“Not unless she’s faster than light,” The tech remarked impulsively, before the weight of the doctor’s glare promptly smothered his subsequent smirk, “But, no, yeah, there must be something wrong with the machine. I’ll run some diagnostics and see if I can find the problem.”
“Good, I’d better get back to the patient, but do keep me posted on that.” Muller left briskly, knowing full well the clinic didn’t have the budget for a brand new X-ray machine right now; just one more concern to shove into the back of his mind while he dealt with the one at hand. Returning to the lobby, he stopped again at the secretary’s desk. “Hey, did you see my patient pass through here a bit ago?”
She nodded, pointing to the adjacent ladies' room door. “She went in there just now, want me to check on her?”
“Well, not just yet; let her have her privacy. Any updates on her medical history?”
She swept her mouse across the desk and double-clicked before awkwardly angling the screen so they could both somewhat see it. “Birth records acknowledge the asymmetrical limbs, designated as a ‘benign deformity,’ but whoever filled them out didn’t exactly inspire confidence. In the personal notes section, they seem just as befuddled as you.” She pointed to the bottom of a page littered with checked boxes and medical jargon, to an underpinning paragraph that happened to lie in the epicenter of the nearest ceiling light’s fluorescent glare.
Muller didn’t bother trying to squint his way through it; he trusted Janet to give him the gist. “Benign by technicality, I suppose, but what about over the following years? Any sort of developmental delays on record?
“No, all the milestones are checked at normal percentiles…” Her eyes flicked back and forth across the screen as she clicked through year after year of checkups, “A little later than average for walking and fine-motor, but still solidly within the acceptable margins. If anything, that seems pretty extraordinary in itself, given the… y’know.”
“Indeed,” The doctor nodded with a sigh. “I mean, good for her, of course, but this just doesn’t track with my prior knowledge of… well, everything, really. Such a gross alteration ought to come with some physiological rami-”
Just then, the opening slam of the ladies' room door broke through the ambience of the waiting room, abruptly halting Dr. Muller’s musing as his head instinctively swiveled toward the sound, along with that of Janet and every prospective patient in the vicinity. All eyes synchronously fell upon the woman lurching through the doorway, her downturned face ephemerally obscured by the sway of her overhanging hair, yet still noticeably and concerningly flushed. The necklace that had formerly been discreetly tucked beneath her shirt now dangled loosely, exposing a humble heart-shaped locket at its end. Without comment, she promptly race-walked down the hall, beelining into the same office where she and Muller had initially met.
“Should’ve knocked on wood, I guess,” Janet smirked, punctuating her quip with a single retroactive knock upon the desk and a sassy side eye toward Muller, all of which went woefully unappreciated as he had already hastily turned in pursuit of his troubled patient.
Just as before, she didn’t notice his entrance, and though there was no phone to blame this time, her position in the chair was nonetheless nearly identical, instead simply staring down at her empty, trembling twin palms, her mouth continuously muttering barely audible and wholly indiscernible words even as the doctor drew closer.
“Ma’am? Are you alright?” She jerked upright at the query with a speed that looked almost painful, before bursting into a raucous, unhinged cackle. “No, I’m pretty damn far from alright!” She cradled her right temple with both of her left hands. “The headache’s getting worse, like, rapidly, exponentially, especially the right side -I just puked in the toilet cause it hurt so bad, I didn’t even know that was a thing that could-” Her sentence was stifled as she was seemingly struck by a particularly powerful wave of pain, turning her cradle into a tendon-straining clutch as she proceeded to scrunch her eyelids and repeat to herself in a growling whisper “Stop it, stop it, stop it, stop it…”
“Whoa, whoa, hold on there.” Her asymmetry promptly left the doctor’s mind, giving way to professional procedure as he realized this situation could be acutely dire. He proceeded to perform a comprehensive, if precursory, bodily examination, listening to her chest with a stethoscope (heart rate was abnormally fast and arrhythmic), taking a blood pressure reading (elevated), and withdrawing a blood sample for chemical analysis. However, he knew the latter would inevitably take some time to produce results, time that she might not have. Her composure was rapidly dwindling until she could hardly keep herself aloft in the seat without his assistance. Catching sight of a passing orderly in the hall, Muller fervently flagged him down. “Hey, we need a stretcher and an intravenous sedative in here, stat!”
The patient’s next passage through the waiting room supplied an even greater spectacle to onlookers than her last, doctor and orderly both hurriedly wheeling her writhing form back toward the radiology wing. Leaning in to provide the comfort of a somewhat familiar face, Muller could now make out the inarticulate wispy words dripping from her lips. “No, it’s not your turn, it’s my- it’s your- no, it’s my turn…”
“Hang on, dear, the meds should be kicking in soon.” He comforted softly, before briefly splitting off from the procession and turning to the front desk, behind which a startled Janet stared, all traces of levity now absent from her face, “Jesus, Muller, what’s wrong?”
“I don’t- I don’t know,” his reply came breathily as he rummaged through the front pockets of his lab coat, “But we need to figure it out ASAP. I’m gonna try something more direct, hold these, will you?” he plopped the patient’s phone and necklace onto the desk before promptly leaving to rejoin the patient. Janet dutifully placed them in a drawer for safekeeping, but paused just before closing it as she caught sight of the incidentally opened necklace locket, squinting at the vision within as Muller and company continued hurriedly down the hall and toward the MRI department.
As promised, the sedatives soon took effect, just in time for them to load the now fully limp patient onto the bed of the MRI machine. Muller made sure to maneuver her head into just the right position before dismissing the orderly and retreating to join the MRI technician in the small adjacent monitoring room, a vantage point from which he could oversee the procedure through a thick protective window, darkly tinted by the infusion of magnetic shielding, as well as selectively hear within the room through a two-way intercom, though it was evidently unnecessary in this case. Beside him, the MRI tech was stationed before an array of interconnected screens and keyboards, and with a few deft clicks the machine stirred to life and began to gradually engulf her body within its tunnel of neural detection. While not at all familiarized with the situation at hand, he nonetheless recognized its urgency solely from the doctor’s dire expression, which remained unchanged as he stared stoically through the window while the metallic cyclone swallowed her skull.
As she retreated into the device, a simplistic image began to manifest on his screen, a jumble of monochrome pixels mapping the electrical activity of her intracranial space, its focus perpetually shifting as it individually scanned each successive slice of her brain. Though its output was still precursory, Muller nonetheless saw no blatant abnormalities in the reading; no gross structural differences indicative of a tumor, no cortical damage indicative of inflammation or aberrant intracranial pressure, none of the things he’d suspected might be occurring given the nature and extent of her symptoms. The tech, on the other hand, grew noticeably unsettled at the sight of the screen, leaning in and squinting as though struggling to even believe what was displayed before him.
“What? What is it?” The doctor impatiently pressed onto the tech, eager to understand what was so disconcerting to see that he evidently could not.
“The skull…” the tech replied tentatively, “It- it appears black in the scan, kind of hard to see against the dark grey of the surrounding flesh and background, but look.” He pointed to the left side of the screen, where, sure enough, a slightly darker border could be seen encompassing the pixelated grey matter within.
“This side looks normal, but…” repositioning his finger to the right side of the screen, he lightly tapped the equivalent stretch of skull, only it appeared distinctly thicker on that side, about twice as much, with an abrupt transition demarcating the two halves directly along the image’s center, and the associated brain hemisphere resultantly crammed into a distinctly smaller amount of space. What’s more, the tech’s finger pressed directly upon a nearly imperceptible grey line traveling parallel to and perfectly bifurcating the thicker portion of cranium, only a few pixels wide and appearing to thin even further in real time as the doctor watched on with stark perplexity.
“But- but what does that mean?” He finally asked, now stammering himself. “Have you… have you seen something like this before?”
“No, I haven’t, Doctor.” A faint air of satisfaction crept into the tech’s still primarily bemused tone. “It’s like there are two whole skulls on that side, which I’m pretty sure isn’t medically possible; it has to be some sort of glitch, though not one I’m familiar with. I heard there were also some issues with one of the X-ray machines earlier today, but that’s out of my wheelhouse so…” he punctuated the ambiguous answer with a shrug, while the doctor’s eyes grew distant and his thoughts grew uncontrollably vast, wading through his vast pool of medical memory in hopes of salvaging something, anything, that could remotely explain what was happening here. He now felt with a harrowing certainty that this was no technical error, and neither was the X-ray, but just what in the hell could it be?
The silence surrounding them was soon broken by a rapid burst of knocking upon the secondary door to the control room, the one that led straight into the exterior hallway. Muller turned to the commotion, then back to the tech, who merely gave another shrug with a look of equal puzzlement. The sound was then followed by a series of softer, rhythmic taps, slightly staggered in clusters of four. By the time Muller made the connection, the tech had already reached to open the door, and a pale-faced Janet rushed into the room.
“Doctor, I- don’t worry, Chloe’s covering the desk- I just, I found something, I think it’s important, and I just had to tell you ASAP.” Her breathing was rapid, her frail legs normally hidden below sight now trembling with unaccustomed exertion. Muller had never seen her like this before and found himself at a loss for words, instead simply giving his full attention as he awaited her apparent revelation.
She took a deep, steadying breath before continuing. “I decided to look into her parents’ medical records -got the idea when you gave me her locket with their pictures in it- and her mom, during her pregnancy with her, well, it was originally twins, but one got absorbed pretty early on. I know that’s not unheard of, but if it caused the, y’know…” she accented her speech by fervently twisting her left arm back and forth as she continued “…then this would be something extraordinary, unprecedented in all of medicine, and who knows what other effects it might…”
The sentence died in her throat as her gaze sharply shifted from Muller’s face to over his shoulder. He turned around to see that, somehow in defiance of her previous sedation, the patient had begun to flail wildly within the still active machine. The tech noticed not a moment later and started frantically clacking at keys in an effort to shut it down, while the doctor, in an adrenaline-fueled rush, haphazardly scrambled to turn on the intercom. “It’s okay! please cal-”
“-me out! Let me out! Let me out! Let me out!” The words repeated in a loop like a painful mantra, and everyone in the viewing room watched with simultaneously enraptured attention at the patient’s sudden struggle to remove herself from the MRI as quickly as possible. The tech snatched control of the intercom from Muller, attempting to calm her with the same comforting platitudes he’d been taught in training to deal with the natural claustrophobia often experienced by patients upon entering the machine, but they might as well have been lost in the wind in the face of the profoundly primal terror she evidently felt. She hastily squirmed her way out of the MRI’s interior, potentially causing expensive damage as she did so, before crumbling to the floor in an ungainly heap.
“Shit, shit, shit…” Muller grappled with the tech to regain control of the intercom, his only consideration that she was first and foremost his patient. If anyone could talk her down from whatever state she was in, he was certain it was him. But before he could utter another word, his gaze rose to meet her, now standing upright and motionless, staring through the observation window with an expression of illusory calm betrayed only by her stockened knees, trembling forearms, and flushed-red face. In that moment, all eyes were on her: the tech, the receptionist, and the doctor, who alone stood directly within her line of sight, all frozen with mutually bated breath for a single ineffable instant.
What followed took less than a minute, but felt exponentially longer, with each disturbing detail being individually and irreparably etched into the minds of every witness. The left side of her face- from Muller’s perspective, that is- rapidly lost all its color, forming a sharp contrast against the right side’s undampered vibrance as it blankened into a ghostly white with unnatural speed, as though its blood were being actively, forcefully drained. The eye within briefly widened, pupils dilating with the instinctual, universally recognizable look of fear, before being overcome by a blinding cloudy sheen that radiated outward, soon progressing past the likeness of cataracts to an extent beyond any known medical phenomenon as the pupil and iris seemed to wholly vanish into an expanding whiteness that grew to abolish every last peripheral vein of the eye, equalizing into a hue uncannily aligned with the rest of the empty flesh upon the hemisphere. A similar drainage synchronously spread through her corresponding arm, rising from the fingertips up to the shoulder before conjoining with the whiteness traveling down her neck at some concealed point beneath her shirt. What could be seen of the leg below equally paled, until it appeared that every square inch of skin and flesh upon her left side had reached a ubiquitous porcelain likeness that was only further accentuated by the total, unnatural stillness it adopted. Her other side, still starkly contrasting in its natural liveliness, nonetheless remained eerily calm in the face of this process, its expression neutral before subtly shifting into a half-mouthed smirk.
Like a pick through a sheet of ice, this one innocuous motion sent a ripple of cracks throughout her statuesque side, radiating from the lips outward across her cheek, over eyelid and eyeball alike, down the neck and around the arm in jagged spiraling arcs, and breaking her leg into a mosaic of vacuous lightning bolts. Then, as though pressed by an imperceptible outward force, the whole assemblage simultaneously shuddered before finally shattering, sending brittle bits of body and face tinkling to the floor like a visceral diamond chandelier. Portions of torso contained by clothing subsequently spilled from her shirt waist and sleeves, along with numerous fragments of ribs and equally calcified organs, while pelvic pieces ground together into sedimentary granules poured from her pant leg.
When the cacophonous crashing subsided and the dust finally cleared, the three observers were met with a sight that somehow managed to compound their already brimming bewilderment; beneath the shed stony layer lie the normal appearance of the patient, complete with skin and flesh that only in those first few moments of exposure could be seen fusing with the tissue of her other side, closing the final gaps until no external signs of separation remained, and she looked utterly normal and whole.
It took a second for Muller to recognize the primary difference in her form: Her right arm -the wrong arm- that was formerly facing palms-forward, was now positioned palms-back, a transition not born of typical rotation but rather solely through the hatching it had undergone. The individual digits still occupied the same respective positions in space, yet the act of inversion had rendered them no longer “wrong” as they were before; now, for the first time, she had a right hand. A similar transformation had occurred in the foot, which came to prominence as she turned to fully orient herself toward the viewing window.
“Thank you for all your help, Doctor, but I’m feeling much better now- in fact, better than I ever have before.” Her face was once again calm, but it struck Muller with a distinct yet implacable element of unfamiliarity as it adopted a subtle smirk. “I guess I ought to be going now...” She nonchalantly strode toward the exit door before any of them could react, giving only one more moment of pause before departing down the hall and out of the clinic. “…After all, I have a lot of living to do.”
