The same afternoon, from the other side of the desk.
He hadn't needed to sit in on the interview. That was the part he'd go back to, later, turning it over like a stone he kept finding in his pocket — nobody had asked him to be there. Admissions ran their own process, Denise was more than capable of evaluating an application on her own, and he had, technically, a full teaching load and a grant proposal due that same week that would have been a perfectly legitimate reason to stay in his office instead.
He'd gone anyway. He'd read the application materials the night before, twice, the second time specifically to check whether his first reaction had been accurate or just the pleasant surprise of low expectations meeting something better than average, and the second read had confirmed it: the deployment model attached to Zarina Immani's application was not average. It was not even good-for-a-student. It was the kind of work he occasionally saw from second-year PhD candidates who'd spent eighteen months getting it wrong before getting it right, except she'd apparently gotten most of it right the first time, on the ground, with actual field data instead of a case-study template.
He told himself he wanted to see the interview because he was curious about the storage assumption on page four, which he genuinely was, and that this curiosity had nothing to do with anything else. He believed this for approximately the first six minutes of the interview, during which she'd answered his question about transformer housing and thermal loss with the specific, unhurried precision of someone who'd actually done the work rather than memorized the summary, and he'd felt the particular, uncomplicated satisfaction of watching a good mind operate at full capacity.
By minute twenty, watching her defend the two-continent management structure she hadn't fully solved yet — watching her admit, plainly, that it wasn't solved, rather than perform a confidence she didn't have — he'd stopped being able to tell himself it was only the model he found compelling.
By minute forty, when she'd laughed at something he said about Lagos traffic and the laugh had done something to the whole room, brightened it in a way he didn't have adequate vocabulary for, he'd understood, with the clean, unwelcome clarity of a man watching a car accident develop in slow motion, that he was in some kind of trouble.
He kept it together for the remaining forty minutes with the professional discipline that had gotten him through a decade of teaching, asked the standard questions when Denise steered them back to standard territory, shook her hand at the door with exactly the correct amount of warmth an admissions committee member owed a strong applicant, and said, we'll be lucky to have you, which was true in every sense he was allowed to mean it and one sense he very much was not.
Then he'd watched her walk down the hallway toward the elevator, and something in his chest had done a thing he hadn't authorized, and he'd gone back into the empty interview room and stood very still for longer than the room had any reason to hold him.
"You're quiet," Denise said, gathering her folder, not looking up. "Good interview, though. I'm putting her at the top of the admit list."
"She should be."
"You want to be her adviser? You lit up like a kid on that storage question. I haven't seen you do the thing with your hands in a while." Denise said it lightly, an offhand professional observation, no weight in it at all, and Josh had felt the words land somewhere he hadn't braced for. "You'd be a good match. Technical rigor plus that deployment mess she hasn't sorted yet. Right up your alley."
"I've got a full load this cycle."
"Sure," Denise said, already moving on to the next folder, the next name, and the conversation had ended there, ordinary and unremarkable, and Josh had gone back to his office and stood in the stairwell for four minutes he would later be unable to account for, running through every version of the last eighty minutes and finding, in each one, the same unwelcome conclusion.
He knew what this was. He'd have recognized it in a student, in a colleague, in a stranger on the street — the specific, disproportionate attention, the way a single laugh had outlasted its own moment and kept replaying, the fact that he'd spent four minutes in a stairwell instead of forty seconds walking back to his desk like a normal person conducting normal professional business. He knew exactly what it was, and knowing it did nothing to make it smaller.
What he thought about, standing there, wasn't really Zarina Immani at all, not directly — it was Marcus, two floors up at the time, still teaching, still likeable, still eighteen months out from the version of himself that would eventually sell insurance in Ohio and stop returning calls. Josh had watched that story from close enough to know exactly how it started: not with anything dramatic, not with anyone crossing a line on purpose, but with a professor who let himself enjoy one student's attention a little more than the job strictly allowed, who told himself it was harmless because nothing had happened yet, who kept telling himself that for months while the harmless thing quietly stopped being harmless at all.
He was not going to be that story. He decided it standing in a stairwell, four minutes after meeting a woman whose mind he already respected more than he was prepared to admit, and the deciding felt, at the time, like the responsible thing, the adult thing, the thing a person with actual self-control did instead of finding out the hard way.
He went back to his office. He did not put his name on the interview follow-up as a requested adviser contact. He told himself this was prudent, forward-thinking, exactly the kind of boundary a careful person built before they needed it rather than after.
He had no way of knowing, standing there with his hand still hovering half an inch from a pen he did not pick up, that the boundary he was so carefully constructing would not, in fact, keep either of them safe from anything — it would just make the next four months a great deal colder than either of them deserved.
