The third pnt was dying again.

  Sora noticed it the way she noticed most things, peripherally and then all at once, the small drooping curl of its outermost leaf catching the edge of her attention while she was supposed to be reviewing the calibration data on her atmospheric pressure model. She looked at it for a moment. Then she looked back at her screen. Then she looked at the pnt again.

  She had named it Outlier because it had survived longer than any reasonable projection suggested it should, given her track record with living things that required consistent intervention. Control, the first pnt, had sted eleven days. Variable had made it to three weeks before developing a condition she could only describe as aggressively giving up. Outlier had been alive for four months and three weeks and Sora had developed something she was careful not to call attachment toward it.

  She got up, filled the small cup she kept on the windowsill for this specific purpose, and watered it. Problem identified. Problem addressed. She sat back down.

  The afternoon light came through the south facing window at the angle it always did at this hour, falling across the desk in a long warm rectangle that moved slowly rightward as the day continued. Sora had calcuted the exact rate of this movement once during a slow afternoon in first year. She no longer remembered the number but she remembered the particur quality of the light and found it reliable in the way she found most things in this room reliable.

  The server hummed.

  This was the sound the room ran on underneath everything else, a low consistent frequency that Sora had calibrated herself and now recognized the way some people recognized music, with an awareness that was half conscious and half simply part of the background of being alive. When it hummed at this frequency everything was running correctly. She had learned to trust it the way she trusted very few things.

  She pulled her notebook toward her and uncapped her pen.

  The notebook was technically the Research Club's official project log, a designation that had become somewhat flexible given that she was the Research Club's only member, its president, its secretary, its treasurer, and its entire operational staff. She used it for whatever needed recording. Currently it held the atmospheric pressure model notes, three pages of calcutions she had run for a separate project she was doing independently of any club affiliation, and a half finished list of variables she wanted to test before submitting her next colloquium entry.

  She had won the national research colloquium four years running.

  She was aware this was unusual. She was also aware that people found her awareness of it somewhat unsettling, as though she was supposed to perform modesty about a fact she had simply verified. She did not see the utility in pretending a correct conclusion was uncertain.

  She uncapped her pen and wrote the date at the top of a fresh page.

  Outside in the hallway someone walked past quickly, their footsteps the hurrying kind that meant they were te for something, and then the hallway went quiet again. The Research Club room was at the far end of the east wing third floor, a location that had been assigned somewhat dismissively when the club was founded and had since become one of its primary advantages. Nobody came to this end of the building without a reason. The quiet was structural.

  Sora liked this about it.

  She had been in this room for a full year as its only occupant and people occasionally asked her if she found it lonely, the question delivered with the slight head tilt that meant they already had a sympathetic answer prepared. She always told them no, which was true, and watched them not quite believe her, which was their prerogative.

  The room did not feel empty. It felt correctly sized.

  She had just returned her attention to the calibration data when she heard the footsteps in the hallway that she recognized without having to think about it. Not the hurrying kind. A comfortable pace. Slightly uneven on the left side when carrying something, a fact she had catalogued without meaning to somewhere in the st two years.

  The door opened.

  Fujiwara Hana came in the way she always did, without knocking, which was a habit so established that Sora would have found a knock disorienting at this point. She was carrying a bento box in one hand and had her student council documents tucked under her other arm, and she was wearing the expression she wore when the day had been manageable, which was different from the expression she wore when the day had been difficult and different again from the expression she wore when something had genuinely pleased her.

  Sora knew all three.

  She also knew approximately eleven other distinct Hana expressions and could have described the differences between them with reasonable accuracy if anyone had asked, which nobody had, because nobody had any reason to ask that particur question.

  "You forgot lunch again," Hana said, setting the bento on the corner of the desk that had been cleared for exactly this purpose, though Sora could not specifically remember clearing it.

  "I had a rice cracker at eleven thirty."

  "That's not lunch."

  "It addressed the immediate caloric requirement."

  Hana sat down on the small couch against the wall, the one that had appeared in the room sometime in early spring under circumstances Sora had never fully investigated, and set her council documents on her knees. She had a way of settling into a space that made it look like she had always been there, like the room had been waiting for her to arrive and could now proceed normally.

  Sora looked at the bento box.

  It was the blue one with the small csp on the side, which meant Hana had packed it this morning rather than picking something up, because the blue one lived in Hana's kitchen and not in any of the school's vending options. She opened it. Inside, divided neatly into sections, was rice and grilled fish and pickled vegetables and in the corner, taking up exactly the right amount of space, three pieces of tamagoyaki.

  Sora ate one.

  It was, as it always was when Hana made it, exactly the right level of sweet.

  "How's the model?" Hana asked, not looking up from whatever she was reading.

  "The calibration is running about four percent off from the projected baseline. I'm deciding whether the variance is meaningful or whether it falls within acceptable parameters."

  "Is it meaningful?"

  Sora considered this with the rice cracker she had not eaten still sitting in her desk drawer. "Probably not. But I'd rather verify than assume."

  "Obviously," Hana said, in the tone that meant she had expected exactly that answer and found it correct.

  This was one of the things about Hana that Sora had never needed to expin. Most people, when she described her work process, developed the look that meant they were trying to appear interested while the actual content moved past them. Hana listened with the particur quality of attention that meant she was genuinely tracking it, even when she admitted she only understood half of the technical specifics. She had told Sora once that she did not need to understand the equations to understand what Sora was trying to do, and Sora had found this a more satisfying answer than she had expected.

  The afternoon light moved its slow rightward degree.

  "The disbandment review is coming up again," Hana said.

  Sora ate another piece of tamagoyaki. "I know."

  "Third week of next month."

  "You'll handle it."

  She said it without looking up from her data, the way she said things that were simply facts rather than requests, and heard Hana make a small sound that was not quite a ugh and not quite an exhale but somewhere comfortably between them.

  "Obviously," Hana said.

  The word nded the same way it always did, easy and certain, and Sora returned her attention to the calibration variance and the question of whether four percent was something she needed to care about today. Hana turned a page on whatever she was reading. The server hummed at its correct frequency. Outside the window the sky was doing the early evening thing where it could not decide between gold and blue and was attempting both simultaneously.

  They stayed like that for a while.

  This was not unusual. Hana spent portions of several afternoons a week in this room, working on her own council business while Sora worked on hers, and the silence between them had the particur quality of silence between people who have never needed to fill it. Sora had spent time in enough social situations to understand that this was not the default. Most silences required management. This one simply existed and asked nothing of either of them.

  She had never thought much about it before.

  She was not thinking much about it now either.

  At some point Hana stood up, straightened her council documents, and tucked them back under her arm. She picked up the empty bento box, which Sora had finished without particurly noticing she was doing it, which was probably the intended effect.

  "Don't stay past seven," Hana said.

  "The calibration needs another two hours minimum."

  "Then stay past seven and eat something before you leave."

  Sora looked up. Hana was already at the door, one hand on the frame, the afternoon light hitting the side of her face in the way that made her look like she was standing inside something warm. She was wearing the manageable day expression still, which meant whatever the council had thrown at her this afternoon had not been more than she could absorb, and Sora found this information settling in the way correct data always settled, neatly and without friction.

  "There are rice crackers in the drawer," Sora said.

  "That's not food."

  "It's technically food."

  Hana gave her the look that meant she had lost this particur exchange and was choosing not to spend further resources on it, which was different from the look that meant she had won, and pushed off from the doorframe.

  "Goodnight Sora."

  "Goodnight."

  The door closed. The footsteps moved away down the hall, the comfortable unhurried pace, slightly uneven with nothing to carry now, growing quieter and then gone.

  Sora looked at her screen.

  The calibration data was still four percent off from the baseline. She pulled the notebook toward her and wrote a note about it, the pen moving across the page in the precise shorthand she had developed over four years of taking research notes in the margins of her own thoughts.

  She was almost done with the note when she realized she was still looking at the door.

  She looked at the door for another moment.

  Then she looked back at her notebook, capped her pen, and returned to the data.

  The server hummed. Outlier, recently watered, sat on the windowsill with the patient quality of something that had decided to keep going for no particur reason.

  The afternoon light finished its crossing of the desk and moved on.
