The waiting room smelled like recycled air and carpet cleaner and the specific anxiety of people who had been told to wait. Marcus Veil sat in a chair with molded armrests and graded exams.
Question four. A student named Kowalski had written that entropy always increases because nature prefers disorder. Marcus drew a line through this and wrote in the margin: Nature has no preferences. Entropy increases because the number of possible disordered states exceeds the number of ordered ones. This is mathematics, not philosophy. His handwriting was small and precise, learned from years of annotating mission briefings in the margins of pages that got classified before they could be read again.
Around him: the soft percussion of a toddler's shoes against a plastic chair, a woman across the room reading something on her phone with her lips pressed together, a television mounted too high on the wall cycling through local news without sound. Albuquerque in October. Through the window, the Sandia Mountains caught the afternoon light and went the particular color of watermelon flesh they went every evening, the thing tourists photographed and residents stopped seeing. Marcus had stopped seeing it sometime around 2009. He marked Kowalski a seven out of ten, which was generous, and moved to the next paper.
A nurse appeared in the doorway and called his name. He capped the red pen.
The neurologist was a small woman named Dr. Patel who had the considered delivery of someone who had learned, through repetition, that there was no way to say certain things that made them easier to hear. She said the images were consistent with what the preliminary scan had flagged. She said the growth pattern was aggressive. She said the location made surgical intervention inadvisable. She used the word inoperable three times, which Marcus noted as either emphasis or habit. Then she said eighteen months, possibly less with rapid progression, possibly slightly more if the neural inflammation responded to palliative treatment, though response rates in this presentation were poor.
He asked his first question: what was the probability distribution across those outcomes?
She was briefly surprised — not by the vocabulary, people surprised her with vocabulary sometimes, but by the stillness with which he asked it. He looked like a man checking a weather forecast. She told him that median survival in similar presentations was fourteen months from confirmed diagnosis. That tails existed on both ends. That her job was to give him the median.
He asked his second question: was there any documented correlation between prolonged exposure to photonic radiation and this presentation specifically, or was that causal link still theoretical?
This time the surprise was more visible. She said that the research was emerging, that there were perhaps a dozen documented cases of radiation-adjacent neural degradation in former Avengers-adjacent personnel, that the mechanism wasn't fully understood but that the correlation was being taken seriously by the medical community. She said the word personnel with the slight discomfort of someone using bureaucratic language to stand in for something larger.
Marcus nodded. He thanked her. She gave him a folder of literature and the names of two specialists in Santa Fe. He shook her hand.
In the elevator he looked at his reflection in the brushed steel doors. He looked exactly like himself.
The drive home was eleven miles. He took Central Avenue rather than the interstate, through the long commercial sprawl of fast food and pawn shops and tire stores that ran the spine of the city. The truck's speedometer needle rested at thirty-five, because the limit was thirty-five. The Sandia Mountains had finished their performance and gone gray. The light was the flat, noncommittal light of early evening that made everything in New Mexico look like an overexposed photograph.
He had spent fourteen years planning for contingencies. He had written tactical assessments for scenarios where the threat was a Kree warship in low orbit and the available assets were two people and a communications blackout. He had learned, across those fourteen years, that the mind's first response to an unanswerable problem was a reflexive search for angles, and that this reflex was either your best quality or your worst one depending on what you did with it. He let the reflex run. The truck held its speed. The light changed and he stopped and waited.
The house was dark when he got home. It was always dark when he got home.
He had bought it in 2006 because it had good bones, Carol had said, and Carol was right about structural things. It was a single-story adobe on the east side with a kitchen that faced west and caught the sunset through a window above the sink. Right now the window framed nothing but the afterglow, the sky going from orange to a greenish nothing above the silhouette of the neighbor's mulberry tree. The kitchen smelled like the rice he'd made two nights ago and left in a covered pot on the stove.
He served himself a bowl standing up. He didn't bother with the table. The rice was cold and he ate it looking out the window, one hand holding the bowl, one hand resting on the counter's edge.
On the counter, six inches from his right hand, Carol's wedding ring caught the last available light and held it.
It was a simple band, white gold, engraved on the interior with the coordinates of a beach in Malibu where they'd had their rehearsal dinner because Carol had wanted the ocean. It had sat there for eleven months, three weeks, and four days. He had not touched it. Not because touching it would make something true that was otherwise false, or because grief was a gravity he was protecting himself from. He simply had not picked it up. He had looked at it. He had looked at it every morning and every evening and sometimes from the couch in the middle of the night, and he had made no decisions about it. It sat there like an unresolved equation. He was very comfortable with unresolved equations.
He set the bowl in the sink.
His phone was in his jacket pocket. He took it out and looked at the screen. Nadia had texted Sunday to confirm their weekly dinner, three days ago. A colleague from the school had sent something about the upcoming grading deadline. There was an automated message from a medical billing department he didn't read. He put the phone on the counter next to Carol's ring and did not call anyone.
He got his briefcase from by the door and sat down at the kitchen table with the remaining exams. Fourteen left. He arranged them in a stack, straightened them against the table's edge, and uncapped the red pen.
Question four. A student named Okafor had written that entropy increases because the universe is running down, like a battery. Marcus looked at this for a moment. The analogy was imprecise in its physics but contained a kind of accidental truth about irreversibility that a more technically correct answer might have missed. He marked it eight out of ten and wrote: The battery metaphor is imprecise but your intuition about directionality is correct. Look up Boltzmann.
Outside, the last light died against the mountains. The kitchen light buzzed once, settled. Marcus moved to the next exam. His handwriting was small and precisely the same as it had always been.
He graded for two hours without stopping.
When he finished, he stacked the papers in order, by student last name, and put them back in the briefcase with the folder from Dr. Patel's office. He didn't look at the folder again. He had read it in the elevator. He had a good memory. This had always been useful and was now, he supposed, somewhat academic.
He rinsed the rice bowl and left it in the drying rack. He turned off the kitchen light. He did not look at the ring as he left the room, which meant he knew exactly where it was.
In the bedroom he lay on top of the blankets with his shoes off, staring at the ceiling, which was the same off-white it had been for eighteen years. Somewhere in the city, distant and without urgency, a car alarm started and stopped. The refrigerator cycled. The house settled into its ordinary silence, the kind of silence that had taken Marcus years to stop measuring against something louder.
Fourteen months, median. He ran the arithmetic once and then let it go, the way he had always let numbers go once they were fixed. The number was fixed. The number was not the problem. The problem, as always, was what you did with the information.
He closed his eyes. He did not sleep for a long time, but neither did he think about anything he couldn't account for. This was a skill. He had built it deliberately, across years of practice in rooms where the stakes were large enough that a mind that couldn't be controlled was a liability. He had controlled his mind until controlling it was all he knew how to do.
Outside, the desert held its enormous silence. The Sandia Mountains were invisible in the dark and the sky above them was thick with stars that had nothing to say about what happened next.
