## Chapter 311 — A Small Physical Answer Thomas woke before the alarm because Isha was no longer breathing like someone asleep. The room remained dark. Sunday traffic had not yet begun below the building, and no light had reached the ion she had taken several hours earlier, separated by enough mattress that neither body warmed the other. Thomas looked at the clock. Five forty-eight. Her breathing paused when he moved. “You are awake,” he said. “Yes.” “For how long?” “I do not know.” Thomas turned onto his back. The dark concealed most of her face, but he could see the pale line of her hair against the pillow. One hand rested on the sheet between them, where it had stopped the previous night. Neither apologised immediately. The argument remained too large for a single first sentence and too recent to disguise beneath breakfast. After a while, Isha asked, “May I hold your hand?” The question hurt more than Thomas expected. Ordinary affection had not required permission between them for a long time. Now uncertainty made the check appropriate, and that appropriateness marked how much had changed. “Yes.” Isha moved only her hand. Her fingers crossed the sheet and settled loosely around his, without pulling him closer. Thomas closed his hand in return. They remained like that until the alarm sounded. --- Breakfast required very little cooperation. Thomas reheated rice while Isha made miso soup. They moved around the LDK carefully, each leaving more space than the other needed. The new floor lamp remained in the flexible room where Thomas had placed it. Its cable curved across the base without the clips. The cardboard box had already gone downstairs with the recycling. Isha opened the balcony door while the soup heated. Cold November air entered the LDK. Thomas, standing beside the rice cooker in a long-sleeved shirt, felt it immediately. “It is four degrees outside.” “The kitchen is warm.” “The heating is not on.” Isha left the door open another handspan. She wore a thin exercise top and loose trousers, yet colour had already reached the skin above her collar. Thomas began to say that she always ran warm. The phrase stopped before becoming reassurance. At the home centre, she had carried the lamp box with her coat open. On their unplanned walk the previous week, she had removed her gloves before he did. She had slept with one leg outside the quilt through most of November and had opened the bedroom window twice after he was already comfortable. Those facts did not explain the argument. They were still facts. “How have you been sleeping?” he asked. Isha turned from the balcony door. “Poorly since last night.” “Before last night.” Her expression tightened. Thomas nearly withdrew the question, then saw her reconsider it. “I wake often,” she said. “Not fully. The room feels hot, or I hear something in the building.” “For how long?” “Several weeks. Perhaps longer.” Thomas pressed the rice paddle against the edge of the cooker until a clump separated. “Do you feel tired?” “Not usually.” “Heart racing?” “After training.” “That is expected.” “Sometimes after.” The soup began to lift beneath its lid. Isha lowered the heat before Thomas could reach it. The movement was efficient and unremarkable. Both of them noticed the lack of correction around it. She had regular kyūdō practice that morning. Thomas asked whether she intended to go. “Yes. I am not unwell.” “I did not say you were.” “No.” Isha closed the balcony door. “You asked a normal question.” Thomas served the rice. The distinction remained on the table with them. --- Fujisaki placed Isha in the second standing group. The morning began normally. Rubber-bow work, makiwara, the borrowed yumi and the sequence of preparation that had started becoming familiar enough to quiet her rather than occupy her completely. Isha’s entry remained clean. She moved with the others without borrowing their timing and struck three times from four arrows. The miss entered the sand beyond the lower edge after a release she knew she had tightened. She did not argue with the result or preserve it as evidence of deeper success. It was simply a less settled shot. During the next wait, she became aware of her heartbeat. Not forceful enough to frighten her. Fast. She had been standing still for several minutes. Her breathing had returned to normal. The pulse in her throat continued at the rhythm of someone who had only just put down the bow. Isha placed two fingers against the inside of her wrist. Ōno noticed. “Are you dizzy?” “No.” “Pain?” “No.” Fujisaki crossed the floor before Isha could decide whether the question required her. She asked Isha to sit at the rear of the waiting area and counted the pulse herself. Her expression did not become alarmed. It did become professional. “Ninety-eight,” she said. “You have been resting.” “Yes.” “Does this happen often?” “I have not checked.” Fujisaki looked at Isha’s face, then at the thin training layer beneath her jacket. “You are warm.” “I usually am.” “That is not an answer to whether something has changed.” The phrasing would have irritated Isha the previous day. Now she recognised the structure from her own voice. She looked down at the yugake in her lap. “I have been sleeping lightly. I sometimes remain hot after training.” Fujisaki told her not to shoot the next set. “I feel capable.” “I believe you.” Fujisaki crouched far enough away that the exchange did not become private theatre for the waiting group. “Capability is not the question. A fast resting pulse with heat and poor sleep has ordinary causes. Some require a clinic. You can return after you know which category this is.” Isha could have objected that ninety-eight was not severe, that she had trained harder without difficulty and that her pulse would probably fall after another ten minutes. All three statements might have been true. She removed the glove instead. Fujisaki gave her the attendance sheet to update before leaving. Isha wrote that she had stopped after the first group sequence because of an elevated resting pulse and would seek medical advice. The reason occupied one narrow line. It did not call her weak, impatient or wrong. Outside the dōjō, cold air reached her face and felt pleasant enough that she remained beneath the entrance roof for several minutes before putting on her coat. --- Thomas had not expected her home before lunch. He was at the dining table with the winter-arrival route sheet open on his laptop when the lock turned. Isha entered carrying the kyūdō bag and no visible distress. Thomas stood anyway. “What happened?” “Fujisaki measured my pulse at ninety-eight after several minutes of rest. She stopped my practice.” Thomas looked towards the clock, as though the hour could determine urgency. “Do you feel unwell?” “No pain, dizziness or shortness of breath. My heart does not feel irregular.” “Sit.” Isha’s expression changed. Thomas heard the command after it had already left him. “Please sit while we count it again.” She put down the bag and sat at the table. Thomas used the timer on his phone while Isha found the pulse herself. He watched the second counter rather than touching her wrist. Ninety-four. They waited ten minutes in the cool room. Ninety-two. Thomas closed the laptop. “Clinic.” “Yes.” There was no argument. The lack of one frightened him more than resistance might have done. They found a general internal-medicine clinic with Monday appointments and completed the online intake together. Thomas entered the recorded accident history and current medicines. Isha added the symptoms she had initially dismissed as separate inconveniences: feeling unusually warm, waking repeatedly, occasional awareness of a fast heartbeat, increased appetite without meaningful weight change and two menstrual periods lighter than her previous pattern. The form asked when the symptoms began. Isha selected **one to three months** and looked at Thomas. “That includes before the argument,” he said. “Yes.” “It does not explain the argument.” “No.” They submitted the form. The appointment confirmation arrived for Monday at ten twenty. --- The remainder of Sunday did not become reconciliation. Thomas returned to the university guide because the first staff test was due before the end of the week. Isha showered, ate the lunch he had already prepared and read the clinic’s instructions twice. She did not ask whether he was hiding inside work. He did not ask whether she was searching for a diagnosis that might make the previous evening less hers. At three, Thomas found her sitting on the bedroom floor with the supplied medical file open beside her. The records contained annual examinations, accident treatment and the ordinary evidence of a human life neither remembered. A previous health check from spring listed a resting pulse of seventy-two. The medical declaration before the Morita bout had recorded seventy-six. Isha pointed to the second number. “It was normal in September.” “That suggests something changed.” “Or today was unusual.” “Yes.” Thomas sat beside her, leaving a small gap. The file lay between them. Isha turned a page without reading it. “I wanted the number to have always been high.” “Why?” “Then it would only be this body.” Thomas understood. A permanent feature could be catalogued. A recent change implied cause, treatment and uncertainty. He folded one corner of the plastic sleeve beneath his thumb, then released it before leaving a mark. “I wanted the clinic form to contain an answer.” “It contained symptoms.” “I know.” Isha looked towards him. “If this is physical, would it make what happened smaller?” “No.” Her gaze lowered. “It might make part of it easier to understand,” Thomas added. “That is not the same thing.” She closed the file. “I do not know whether I want understanding or permission.” “I don’t think a blood test can give permission.” “No.” The answer came without correction or defence. Thomas moved his hand onto the floor between them. Isha placed hers beside it, not over it. Their little fingers touched. That was all. --- The clinic nurse measured Isha’s pulse at ninety-six on Monday morning. Her blood pressure and temperature were normal. Oxygen saturation was normal. The electrocardiogram showed a fast but regular sinus rhythm rather than an arrhythmia. The nurse repeated the pulse after Isha had sat in the examination room for another ten minutes. Ninety-three. The physician was a woman in her fifties with short dark hair and a voice that remained level whether asking about sleep or explaining why a normal electrocardiogram did not end the investigation. She examined Isha’s neck, listened to her heart and asked her to hold both hands forward. A slight tremor appeared at the ends of her fingers. It was small enough that Isha had not noticed it while tying laces or handling the bow. “No pain in the neck?” “No.” “Difficulty swallowing?” “No.” “Eye discomfort, dryness or changes in vision?” “No.” The physician asked about supplements, energy drinks, weight-loss products and medicines. Isha used none. She drank coffee occasionally and had eaten no breakfast that morning because the clinic had asked her to attend prepared for possible blood work. “Pregnancy possible?” “No.” “Family thyroid disease?” Isha paused. The supplied records contained no family thyroid diagnosis. She had no access to the biological history behind the body. “None recorded.” The physician accepted the distinction without asking why it was phrased that way. She ordered thyroid-stimulating hormone, free T4 and T3, thyroid antibodies, full blood count, liver tests and inflammatory markers. Thomas watched the labels being attached to the tubes. Blood looked ordinary coming from Isha’s arm. There was no sign in it that the body belonged to a woman who remembered another species. Afterwards, the physician asked whether either of them had another concern driving the appointment. Isha looked at Thomas. He did not answer for her. “I have been more irritable,” she said. “Not angry without cause. Quicker to decide that another person is wrong.” The physician waited. “I have been controlling towards my partner.” Thomas kept his hands still on his knees. Isha continued. “Could a thyroid problem cause that?” “It could contribute to irritability, restlessness, poor sleep and feeling constantly activated,” the physician said. “That can shorten patience. It cannot tell us why you responded to one person in a particular way, or why a behaviour became repeated.” “So it may make stopping harder.” “Yes. That is plausible.” The physician turned slightly towards Thomas without making him the subject of the consultation. “It does not establish what happened between you.” “No,” Thomas said. The physician looked back at Isha. “We should first determine whether your thyroid is involved at all. Do not build an explanation before the result.” Isha gave a short nod. Thomas recognised the advice as one she might once have supplied to him. The recognition carried no satisfaction. --- The preliminary result arrived through the clinic portal on Tuesday afternoon. Thomas was at work when Isha sent him a screenshot. **TSH: below measurement range. Free T4: mildly elevated. T3: elevated. Further antibody result pending.** Beneath the numbers, the clinic had added a request for follow-up the next morning and an instruction to seek urgent care for chest pain, fainting, marked breathlessness or a sustained severe racing heartbeat. Thomas read the screen until Sugiyama asked whether the entrance-source note had changed. “No,” he said. “Sorry.” She glanced at his phone but did not ask for details. “Then Facilities remains the owner of the blank.” Thomas returned the phone to the desk. **I can leave now**, he wrote to Isha. Her answer came immediately. **You can finish work. I am not in danger. Come home at the normal time.** Thomas began typing that she could not know that with certainty. He deleted it. **All right. Tell me if anything changes.** The exchange ended there. At five twenty-nine, he closed the winter-arrival guide and left. Isha had already eaten when he reached flat 202. A covered bowl of stew waited in the refrigerator. She sat at the dining table with the medical portal open and the clinic leaflet beside it. Thomas put down his bag. “How do you feel?” “The same.” He reheated the stew. Isha remained at the table rather than standing beside him and explaining the safest sequence of lid, microwave and stirring. Thomas wished she would. The wish was not reasonable, but it was real. Her ordinary confidence had filled much of their home. Its sudden removal did not feel like equality. It felt like an absence shaped exactly like her. He carried the bowl to the table. “I do not want you to stop speaking,” he said. “I am trying not to direct you.” “Those are not the same thing.” Isha looked at the leaflet. “I no longer know where the line is.” “Neither do I. That is part of the problem.” She folded the leaflet once, then flattened it again. “The blood result is real.” “Yes.” “I was relieved.” “So was I.” The admission brought her eyes up. Thomas took a spoonful of stew before continuing. “I wanted there to be something physical because I thought it might mean you had not chosen any of it.” “And now?” “Now I think that was unfair in both directions. It would erase what you did and make your body guilty for decisions it did not make.” Isha’s fingers pressed against the fold. “I still made them faster than I used to.” “Maybe.” “I was always decisive.” “Yes.” “I was not always like this with you.” “No.” Neither tried to identify the exact month in which the difference had begun. The portal updated while they sat there. A second result appeared: antibodies associated with Graves’ disease were positive. The clinic message changed from **possible thyroid excess** to **likely early Graves’ hyperthyroidism**, with referral to an endocrine clinic for confirmation and treatment planning. Isha read the phrase twice. “It has a name,” she said. Thomas looked at the ordinary black letters. “Yes.” The relief returned in a smaller, more dangerous form. A named condition invited them to put too much inside it. Isha closed the phone cover. “We will not use the name to finish the argument.” “No.” “We may use it to explain the pulse.” “Yes.” “And the heat. The sleep.” “Probably.” She looked towards the flexible-room doorway. The lamp remained switched off, its base six centimetres farther forward than she preferred. “Not the lamp,” she said. Thomas almost smiled. “Not the lamp.” --- The endocrine clinic fitted them into a cancellation on Wednesday morning. The specialist reviewed the results, repeated the neck examination and used ultrasound to examine the thyroid. The gland was mildly enlarged and evenly active in appearance, without a suspicious nodule. There were no eye signs, no irregular rhythm and no evidence of an acute dangerous complication. “Mild Graves’ hyperthyroidism,” the specialist said. “Early enough that your athletic fitness may have hidden some symptoms. The heart rate, heat sensitivity, lighter sleep, tremor and menstrual change are consistent.” Isha sat upright beside Thomas. “And irritability?” “Consistent.” “Aggression?” The specialist shook her head. “That is not a diagnosis we can make from thyroid hormone. Some people become anxious, impatient or emotionally reactive. Some do not. Hormones can alter how strongly or quickly you respond. They do not choose your beliefs, relationships or conduct.” Isha accepted the answer without looking towards Thomas. The specialist recommended a low dose of thiamazole, with repeat thyroid function, liver tests and blood count. She explained that improvement would take time rather than arriving with the first tablet. She also explained the uncommon but serious risk of a dangerous fall in white blood cells: fever or a sore throat meant stopping the medicine and obtaining urgent medical advice and a blood count. A beta blocker was discussed and left unused for the moment. Isha’s rhythm was regular, the pulse was below one hundred and medication that suppressed heart rate might interfere with recognising exertion during climbing work and training. She was instructed to reduce hard exercise until the thyroid levels and resting pulse improved, inform the climbing centre, and pause combat training. Kyūdō could resume only after the treating clinician was satisfied with her resting symptoms. Isha asked practical questions about work, fertility, food, alcohol and how quickly the condition might change. The specialist answered each without treating her athletic ability as proof that risk did not apply. Then Isha asked the question again in a different form. “If the treatment makes me calmer, how much of my behaviour should I consider illness?” The specialist put down the pen. “I cannot divide your behaviour into a laboratory percentage. Treating the thyroid may improve sleep, reduce physical agitation and give you more patience. That may make other work easier. It will not perform that work.” Thomas felt Isha’s hand move on the chair between them. It did not reach for his. The specialist continued, “Do not ignore a medical contribution because it is incomplete. Do not use it to explain more than it can.” Isha bowed her head once. “Understood.” --- They collected the medicine from a pharmacy two streets away. The packet was small. The warning sheet was not. Thomas read every line while they waited for the bus. Isha allowed him to finish without remarking that she had already read the same information beside the dispensing counter. Cold wind moved along the road. She wore her coat closed for the first time that week. “I hoped the doctor would say it was half,” she said. “Half of what?” “Half the reason.” Thomas folded the pharmacy sheet along its existing crease. “Would that have helped?” “It would have given me a number to remove.” “And left the other half.” “Yes.” The bus arrived. They sat together near the rear, shoulders close but not touching. The heater pushed warm air along the floor. After two stops, Isha opened the neck of her coat. Thomas looked at the movement. She noticed. “This part may be the thyroid.” “Probably.” A few minutes later, she said, “I thought I was becoming clearer.” Thomas waited. “I decided quickly. People often agreed. Coaches advanced me. Customers listened. You liked when I took control.” Her eyes remained on the road ahead. “I thought the lack of hesitation meant I understood more.” “Sometimes you did understand more.” “That made it easy.” “Yes.” She turned her hands palm-up on her knees. “I may only have been becoming quicker.” Thomas placed the folded pharmacy sheet between them on the seat. “The doctor said the medicine might slow part of that.” “Not enough.” “No.” This time their shoulders touched when the bus turned. Neither moved away. --- At home, Isha placed the first tablet on the dining table and poured her own water. Thomas watched without hovering. She swallowed the medicine, checked the time and recorded it in the clinic application. Nothing changed visibly. Her face remained the same. The flat remained divided by unfinished understanding. The floor lamp stood in the flexible room. Isha entered, crouched beside its base and picked up the packet of cable clips. Thomas remained in the doorway. “Do you want these fitted?” she asked. “Yes.” “Where?” Thomas sat on the floor opposite her. He indicated the route he wanted: one clip behind the base, one beneath the lower joint, leaving enough slack to move the lamp forward when the chair was used. Isha examined the curve. “That will show more cable.” “I know.” She passed him the first clip. Thomas peeled away the backing and pressed it into place. Isha held the base steady without moving it. They attached the second clip together. The cable remained visible for six centimetres before disappearing behind the pole. The arrangement was not the one Isha would have chosen. It worked. When they stood, Thomas switched the lamp on. Warm light reached the chair and part of the bookshelf. The cupboard door still cleared the base. Isha looked at the result without offering a verdict. “I do want your opinion,” Thomas said. “The cord would be neater behind the pole.” “I know.” “The light reaches the book properly here.” “Yes.” She looked towards him. “Then I prefer this position.” Thomas’s first impulse was to ask whether she meant it or was practising agreement. He let the question pass. Not every uncertainty needed immediate resolution. That night, they went to bed at the same time. Isha lay on her back. Thomas settled beside her, leaving less distance than before but not closing it completely. The medicine packet remained in the kitchen with its warnings and follow-up date. After several minutes, Isha said, “I want to hold you.” Thomas listened to the sentence rather than searching it for control. “Not tonight,” he said. Her breathing altered once. “All right.” She did not turn away. Her hand remained open on the sheet between them. Thomas placed two fingers into her palm. Isha closed her hand gently around them. The answer was physical. It was also small.
