## Chapter 323 — Normal Operation The eighth page began with a sentence Thomas disliked and Isha refused to remove. *The machine that moved us has admitted that part of Isha’s human body was made incorrectly.* Thomas sat at the dining table on Monday evening, 25 January, with the Common-language draft on his laptop and a printed test copy beneath one hand. The passage had not opened yet. Thirty cycles from the seventh sending would complete sometime the next day, unless the System’s counting differed from theirs by enough hours to make preparation irritating. “The word *made* exceeds the evidence,” he said. Isha read the sentence again from the chair beside him. Her resting pulse that morning had been fifty-five. The number now appeared only once in the day’s clinic log rather than in three handwritten comparisons. “It called the problem a system error in a female unit.” “It called it a biological defect.” Isha drew the printed page closer and placed her thumb beside the copied message. “And later said it was resolving safely. A defect belongs to the thing that produced the unit.” “Or to the unit after production.” Thomas moved the cursor into the sentence and left it blinking there. “Graves’ disease could have developed through human biology after arrival.” “The machine claimed jurisdiction over its resolution.” Thomas looked from the screen to the paper beneath Isha’s hand. “That part is stronger.” Isha folded her arms. “Then improve the sentence without making it harmless.” Thomas tried three alternatives. The first became so cautious that Kelda would assume the uncertainty mattered more than the event. The second required a distinction between autoimmune disease and construction error that their prior page had not supplied. The third sounded like an apology written on behalf of the System. He returned to Isha’s version and changed only one word. *The machine that moved us has admitted that part of Isha’s human body may have been made incorrectly.* Isha looked at *may* while Thomas waited beside the blinking cursor. “Keep it. Kelda will know which of us inserted it.” “That is unfair.” “It is accurate.” The page continued with the first System message exactly as it had appeared: **FEMALE UNIT BIOLOGICAL DEFECT RESOLVING SAFELY** They had debated whether block capitals would carry the machine’s tone through Common. Thomas believed the distinction between ordinary written language and System text mattered. Isha believed Kelda would understand that no person had composed those words once she saw the phrase *female unit*. They retained the capitals. The medical account used terms already established on the seventh page. Isha’s small throat gland had returned close to its expected size. The blood instructions that once drove heat and heart speed had entered the normal range. The harmful immune signal had fallen almost to the limit Earth healers could measure. Her resting heartbeat now remained in the middle fifties, which was normal for her trained body rather than dangerously slow. *The daily medicine has been reduced, not abandoned. Earth healers remain responsible for treatment. We will not use the machine’s reassurance as permission to ignore them.* Thomas had written that line. Isha had moved it higher on the page. The relationship paragraph occupied less space than the one before it. *We spoke plainly about habits that followed us from dangerous roads into a safe home. Thomas feared that speaking would make Isha leave. Isha feared that being stopped meant she had become unsafe to love. Neither fear became true. We are happier and less careful in the wrong ways.* Thomas’s eyes returned to the final sentence. “That may be too polished.” “It is shorter than the argument.” Isha placed one finger beneath it before he could begin another standard. “Do you disagree with it?” “No.” “Then Kelda may have one good sentence.” The rest of the page gave her ordinary life. Kanno’s booklet was entering its first small print run. She had watched the new year arrive in flat 202 and brought another fantasy series in which an elf wore unsuitable clothing while pursuing a mage who preferred maps. Dorra, the dwarf, cared almost entirely about stone. *You would approve of Dorra’s priorities and object to her sampling records,* Thomas had written. Isha added that Thomas had used a modern bow for the first time, struck the target several times and treated every arrow that reached the backing wall as a partial administrative success. Her own kyūdō had resumed. She was also returning to recreational climbing under Earth medical limits. They ended with three questions. Had Green Road received the seventh page? Had the station route moved any more healers or injured workers? Had Erenai been given the chair Isha had ordered Kelda to provide? The final line contained no medical explanation. *The snow has mostly gone. Thomas’s lamp cable remains visible. This is also good.* Isha read both sides one last time. “Print it.” Thomas did. The sheet emerged with Common glyphs even and dark across both faces. Isha checked the margins while Thomas closed the file. The page waited beneath a clean weight overnight. At seven fifty-three on Tuesday evening, the passage opened. Thomas felt it while putting away the dinner plates. The awareness entered behind his eyes with no pain: a direction becoming possible, an administrative route recognising its interval. He set the second plate in the cupboard and closed the door before speaking. “It is open.” Isha stood at the sink with her hands in warm water. She finished rinsing the bowl she held, placed it on the rack and dried her hands properly. Neither treated the opening as a reason to leave soap on the dishes. The flexible room already contained the passage mat, water and timer. Thomas had reviewed the safety note after work. Isha had charged both phones and confirmed that the building address remained visible beside the emergency-call instruction. The last protected sending had kept him unconscious for forty-five seconds. They retained the five-minute emergency threshold because several good events did not delete the fourth receipt. Before entering the room, Isha took her evening half-tablet. Thomas watched her record the dose. “The machine may object to being placed after medicine in the sequence.” “It may improve its communication.” The page lay flat on the mat. Thomas sat with Isha behind him, her legs braced on either side and one arm crossing his chest. The position had become procedural through repetition and remained intimate because procedures did not remove the body holding him. He placed his right hand over hers. “Kelda Flintvein of Green Road,” he said. “I send what Isha and I chose to send.” Recognition settled around the name. Thomas accepted the route. Grey-white interference crossed his sight. **PROTECTION ENABLED** The page vanished. His body released at once. Isha caught the weight against her, guided his head and lowered him onto his right side. The timer began. His breathing remained even. The pulse beneath her fingers was regular and slower than her own had been during the first send. At thirty-eight seconds, his eyelids moved. He drew a deeper breath at forty-one and opened his eyes at forty-three. Isha stopped the timer. Thomas looked at the lamp, then at her. “Flat 202. Sendai. Tuesday, twenty-sixth of January.” “No pain?” “No. No nausea, weakness or visual change.” He sat after several breaths and drank from the water bottle. The room remained stable. No pressure gathered behind his eyes. His hands obeyed him without delay. The first notification formed. **TRANSFER SENT** A second line followed. **30 CYCLES TILL NEXT PASSAGE** Thomas waited. The seventh sending had produced the medical message only after the ordinary transfer status completed. Isha watched his face rather than asking too soon. The interface returned. **FEMALE UNIT BIOLOGICAL SYSTEM ERROR** The next line formed beneath it. **RESTORATION COMPLETE** Then a third: **NORMAL OPERATION RESUMING** The words held for several seconds. Thomas read them aloud exactly. Isha sat back on her heels. Her hand went to the front of her throat, not from pain but because the body had become the subject of a machine again. “System error,” she said, testing the new wording aloud. Thomas agreed, and Isha’s gaze sharpened. “It no longer calls it only a defect.” Thomas closed his eyes and checked for another line. Nothing followed. “No. It is admitting responsibility more clearly.” Isha repeated the second line under her breath. “Restoration complete.” “That is what it says.” She counted her pulse beneath two fingers. The beat remained steady. No surge, chill, weakness or shift in the shape of herself followed the announcement. “Then whatever it was doing has ended.” “Possibly.” Thomas opened his eyes. “The repair could be complete while monitoring continues. *Normal operation* may refer to your body, not the System’s involvement.” Isha kept her fingers at her wrist through two more beats. “The earlier word was *resolving*. Now it is *complete*, and I feel nothing.” “That may be the *safely* part.” Isha lowered her hand from her throat. The answer pleased her more than she wanted to grant the machine. A process that had influenced her heart, sleep, heat and patience appeared to have ended without replacing any recognisable part of her. She looked at the medicine packet on the side table. “I take the tablets until the clinic tells me otherwise.” “Yes.” “If the blood is normal after the machine has stopped acting, that supports our reading.” “It supports it. The medicine will still be acting.” Isha gave him a level look. “You may qualify the sentence after I finish it.” Thomas’s mouth moved. “That sounded normal.” “It was.” He reached for her. Isha leaned into the embrace, one arm around his shoulders and the other broad across his back. His heartbeat remained steady against her chest. They recorded the event before bed: **Eighth outgoing page. Tuesday 26 January. Protection enabled. Unconscious forty-three seconds. Immediate stable orientation. No pain, nausea, visual change, weakness or confusion. Transfer sent. Thirty cycles until next passage. Additional message: FEMALE UNIT BIOLOGICAL SYSTEM ERROR / RESTORATION COMPLETE / NORMAL OPERATION RESUMING.** Thomas added one interpretation beneath it: **Probable end of active correction. Not confirmed. Continue ordinary medical treatment and follow-up.** Isha read the line and left it unchanged. Her resting pulse on Wednesday morning was fifty-four. --- The repeat blood had been drawn on Thursday. By Friday afternoon, 29 January, the results occupied two screens in the endocrinology consultation room. Isha sat beside Thomas with her scarf folded across her lap. The specialist compared the current values with those from diagnosis and the early-January review. She moved slowly through the page, checking dates and units before speaking. “Your thyroid hormone levels are normal,” she said. “Not merely within range. They are now close to the centre of the reference intervals.” Free T4 had risen slightly from the low-normal value seen while Isha remained on the larger dose. T3 was stable. TSH had recovered fully and sat in the ordinary range rather than remaining suppressed. The blood count and liver tests were also normal. The specialist scrolled to the antibody result and paused there. “TRAb is now below the laboratory’s detection threshold.” Thomas looked at the figure. The result contained a less-than sign followed by the assay limit. Isha asked, “Does that mean the immune signal has stopped?” “It means this test cannot detect it in the blood sample. That is an excellent sign. It does not allow me to promise that the disease can never recur.” The specialist opened the earlier graph. “The speed is unusual. Your first value was clearly positive six weeks ago. The fall at the previous test was already strong. This result is the most favourable outcome we could have received.” The System had called its work complete three days earlier. Thomas kept that timing outside his face as much as possible, though the ultrasound made concealment harder. Isha lay with her neck extended while the specialist measured each lobe and the narrow tissue between them. The gland had returned to an expected volume for Isha’s body. The increased blood flow seen at diagnosis had resolved. No nodules, damaged areas or abnormal structural changes appeared. The specialist repeated one measurement, adjusted the probe and obtained nearly the same figure. “The enlargement has resolved,” she said. “The tissue looks normal.” Isha stared at the ceiling. “Normal as though Graves’ disease is controlled, or normal as though it was not there?” “The scan cannot answer that distinction. It shows a normal-sized gland with normal vascularity. Combined with the blood results, you are in biochemical remission.” The word *remission* carried less certainty than *restoration complete*. It belonged to medicine rather than machinery and therefore deserved more trust. Back in the consultation room, the specialist reviewed the dose sheet once more. “I would not ordinarily expect to stop antithyroid treatment this early,” she said. “Standard courses are much longer because early biochemical control does not usually mean the autoimmune process has ended. Your case is not following the usual timing.” Isha waited. “Continuing even this reduced dose now risks pushing you towards hypothyroidism. Your antibodies are undetectable, the gland has normalised and you have no symptoms. Stop the thiamazole from today.” Thomas’s hand tightened once around the edge of his chair. The specialist continued before either could turn the decision into certainty. “We repeat thyroid function and antibodies in two weeks. Then again at increasing intervals if they remain normal. Contact us earlier for renewed palpitations, tremor, heat intolerance, unexplained weight change or persistent fatigue. I am calling this unusually rapid remission, not a permanent cure.” Isha looked at the medication schedule. The final half-tablet had been taken the previous evening. “No taper?” she asked. “The dose is already small, and the drug does not require tapering in this situation. We stop and monitor.” The specialist checked Isha’s pulse manually. Fifty-eight in the consultation room, regular and strong. Blood pressure normal. No tremor when she held out both hands. No eye signs. No tenderness or palpable enlargement at the throat. “Activity?” Isha asked. “You may return gradually to normal training. Your cardiovascular response has been appropriate, and there is no current biochemical reason for broad restriction.” The specialist lifted one finger before Isha could interpret *normal* expansively. “Do not test every maximum in the same week. Increase one demand at a time. Running, strength training, climbing, kyūdō and technical combat work are reasonable. Hard sparring and competition preparation should return after you have shown stability off medication.” Isha accepted the line. “Two weeks.” “At least until the next blood result.” Thomas asked whether the remission could have occurred spontaneously. “Yes. Graves’ disease can remit, especially when mild and treated early. What is unusual is the completeness and speed. Medicine often gives us probability, not a reason why one person lands at the favourable edge.” Thomas kept the phrase *favourable edge* in memory. It fit too well to count as evidence. Outside the clinic, Isha stopped beneath the covered entrance. Fine snow had begun, too sparse to settle on the pavement. She took the thiamazole packet from her bag and looked at the tablets remaining inside. Thomas stood beside her. “We keep them until the clinic confirms disposal.” Isha turned the packet once in her hand. “I was not about to throw them into the road.” “I know. I wanted to say something responsible.” “You succeeded.” Isha put the packet away. Her face remained composed until the zip closed. Then she turned, placed both hands around Thomas’s face and kissed him beneath the clinic canopy. A woman passing with a clear umbrella looked away with efficient courtesy. Thomas’s hands settled at Isha’s waist. When she drew back, his smile had become too broad to disguise. “No medicine tonight,” she said. Thomas’s hands tightened at her waist. “No medicine tonight.” “The gland is normal. The antibodies are below detection.” Isha heard the facts together and laughed once, a short breath of sound that seemed to surprise her. “I am well.” Thomas’s expression softened. “You are.” The words did not mean invulnerable. They did not guarantee that antibodies could never return or that the System had no other errors hidden inside either body. They meant that every available Earth measurement now described health. That evening, the medication alarm sounded at its usual time. Isha looked at the phone. Thomas looked at her. She cancelled the alarm permanently. --- On Sunday morning, Isha returned to the municipal archery range with a twenty-six-pound recurve. Nakahara had suggested the draw weight after watching her use the sixteen-pound beginner bow. It was modest for her strength and heavy enough to behave more like the club bow Kuroda had helped her use during her first Earth-side sessions. The range was set at eighteen metres. Isha attached a long stabiliser, adjusted the sight and spent several minutes checking brace height and limb alignment. Thomas sat behind the waiting line with coffee and the shoulder that had mostly forgiven his own lesson. “You appear happier with more components,” he said. “The components each have a purpose.” Thomas watched her turn the sight adjustment through two clicks. “You distrusted my argument in favour of the blanket divider.” “That component had no stable function.” “It divided the bed symbolically.” Isha checked the string against the limb groove. “For four minutes.” Nakahara looked towards them from lane two. “Shoot before the equipment becomes part of the relationship discussion.” Isha obeyed. The first three arrows grouped left of the gold. Her release was clean, but the sight setting belonged to another archer and the bow’s balance differed from the traditional equipment she had been learning at the dōjō. She adjusted two clicks and shot again. One arrow entered red. Two reached gold. The body felt quiet through the draw. Before diagnosis, her modern archery had remained accurate enough to impress anyone who did not know her own standard. The hidden tremor had been too small for most people to see. Heat and poor sleep had done more damage, shortening patience at full draw and making fine corrections feel like delay rather than information. Now the sight pin moved because a human body could not become perfectly still. It moved within a smaller field. Her pulse arrived as a steady event rather than a demand. She raised the third end. The stabiliser settled. Her shoulder line opened. The string reached her face at the same point three times. Gold. Gold. Inner gold. Thomas leaned forward behind the line, but Isha did not look at him until the collection signal. Her group measured less than the width of her palm. She marked the sight change in a small notebook, retrieved the arrows and returned without needing praise to confirm the result. Thomas gave it anyway. “That was better than before.” Isha rested the arrows against her hip. “You did not see enough of my earlier modern shooting to know.” “I watched the first range sessions, and I saw the target photographs in the supplied archive.” Thomas lifted his coffee before she could answer. “You inspected those closely?” “They were evidence.” Isha waited with one eyebrow raised until Thomas added into his cup, “That my partner is offensively competent.” Her mouth moved as she returned to the line. Over the next six ends, the group tightened. Not every arrow entered gold. One release left her fingers poorly and landed in blue. Another drifted high after she held too long. The errors remained legible and correctable rather than symptoms demanding interpretation. Near the end of the session, she shot six arrows in a group small enough that two nocks touched. Nakahara examined the target after the collection signal. “Your control improved substantially through the session.” Isha looked at the cluster. “I was unwell before.” “So I understand.” He touched neither arrow while inspecting their angle. “Do not mistake feeling better for permission to double the draw weight.” “I will not.” Thomas joined them at the target and announced his support for the instruction. Isha glanced towards his right shoulder. “You used sixteen pounds.” “That is why my support is informed.” She removed the arrows one by one, pulling straight from the target. Her last end had been better than the groups recorded before diagnosis, but the improvement did not feel like a gift added from outside. It felt like obstruction removed: better sleep, steadier regulation, a body no longer spending effort against itself. Thomas carried the bow case when they left. Isha allowed it because his shoulder no longer hurt and because shared equipment did not require a larger argument. --- The climbing centre was quiet on Tuesday evening, 2 February. Isha was off duty. She wore a dark fitted top and black full-length climbing leggings, with her pale hair braided high enough to keep it clear of the harness. Thomas sat near the rope area with his coat folded beside him and no work file open on his phone. Takeda had approved recreational climbing after reading the specialist’s return note. The plan remained bounded: warm-up routes, one harder technical route, no rescue drills and no attempt to establish a strength maximum while several metres above a floor. Sato belayed. The first route felt almost insulting. Isha climbed it to check fingers, feet and pulse response rather than difficulty. Her movements stayed close to the wall. The old habit of listening for tremor or inappropriate heat found nothing. She lowered, rested and chose a steeper blue route set across the centre panel. The holds were smaller, the sequence less direct and the middle section required a high right foot followed by a controlled turn beneath an overhang. Strong climbers often tried to pull through it and arrived at the next hold with both arms already tired. Isha studied the route from the floor for less than a minute. Thomas watched her eyes move from hold to hold. “You have decided.” “I have a first answer.” “That usually becomes decisive for architecture.” “This wall may disagree.” She tied in, completed the partner check and began. The opening moves carried no display. Left foot, high hand, hip close. She crossed beneath the first volume and let the rope move behind her without touching it. At the overhang, she placed the right foot high enough that her knee rose beside her ribs. The leggings drew cleanly across her hip and thigh as she turned. Thomas stopped looking at the next hold. Isha reached it, settled into the position and looked down. Their eyes met across eight metres of air, and Thomas wore the particular innocence he used only after being caught. “Route,” Isha called. “Excellent, Lysenne.” Sato looked from the rope to Thomas. “Who?” “An elf with poor clothing logistics,” Isha said. Thomas kept his gaze on her face now. “The current fan service is more structurally responsible.” “I am wearing full-length leggings.” “Yes.” His smile widened. “Your fan remains well served.” Sato looked at the ceiling as though the belay certification had not covered this situation. Isha laughed on the wall. The sound loosened her more effectively than another rest. She turned back into the route, moved the left foot onto a narrow edge and shifted her centre through the overhang without pulling. The sequence that once would have depended partly on raw strength became almost weightless through timing. She reached the next hold with the right hand already relaxed. Thomas forgot the leggings for several moves. Her climbing had always combined elven movement memory with an exceptional human body. Before diagnosis, the strength remained, but small errors had accumulated: a grip held harder than necessary, a foot corrected half a second late, impatience turning a balanced sequence into a pull. None had made her look unwell. They had made the climbing less entirely hers. Now every part arrived in order. She used a heel hook beneath the final roof, extended through the left side and released one hand long enough to shake it. Her breathing remained controlled. The body did not demand speed or punish stillness. At the finish, she touched the final hold with both hands and remained there long enough to look down at Thomas again. He raised both thumbs. She lowered under Sato’s control. Her feet touched the mat. The pulse at her wrist was one hundred and four, then eighty-two after two minutes and sixty-eight after five. Normal rise. Normal recovery. No tremor or inappropriate heat. Takeda had watched the final section from reception. He crossed over after the rope was untied. “That was cleaner than your autumn ascent,” he said. Isha looked back at the blue route. “The middle felt slower.” “It was. You spent less energy.” She flexed both hands. The forearms felt used rather than flooded. Her shoulders remained loose. Sato coiled the rope and said, “You could have pulled through the high step.” “Yes.” “You didn’t.” “It was worse.” Sato accepted that as a complete technical explanation. Thomas came from the waiting area carrying her water bottle. He handed it over, eyes moving once along the full length of the leggings with no effort to disguise the appreciation now that she stood safely on the floor. Isha drank. “Lysenne?” “You looked down at your audience during the exact shot the director would have selected.” “There was one person watching me incorrectly.” “Your fan.” She lowered the bottle. “Did you enjoy the climb?” Thomas’s teasing left enough room for the honest answer. “Very much. You were extraordinary.” The word no longer made him sound smaller beside her. It described what he had seen and the pleasure he took in seeing it. Isha touched the side of his face with two fingers. “You missed two moves.” “I saw them during the first attempt.” “There was only one attempt.” Thomas looked towards Sato for assistance. Sato carried the rope away. They remained until the centre began preparing for closing. Isha climbed one easier route to cool down and stopped while the body still felt capable of more. No restriction forced the decision. She wanted the next test to have its own day. In the changing area, she entered the climb and pulse recovery in the private training note. Beneath it, she added two headings. **RUNNING** **WEIGHTS** Thomas read them when she showed him the screen outside. “Separately,” he said. Isha put on her coat. “Track first. Bar after.”
