She nodded at the window, the lengthening daylight.
"Thank you," Jason said gently. "Tyler, if you need a break, this would be the time. But don't be too long."

I looked in on Diane, who was between episodes, sleeping. I thought about the Martian drug I had administered to her (the "basic Fourth," as Jase had called it), semi-intelligent molecules about to do battle with her body's overwhelming load of CVWS bacteria, microscopic battalions mustering to repair and rebuild her, unless her body was too weakened to withstand the strain of the transformation.
I kissed her forehead and said gentle words she probably couldn't hear. Then I left her bedroom and went downstairs and out onto the lawn of the Big House, stealing a moment for myself.
The rain had finally stopped—abruptly, completely—and the air was fresher than it had been all day. The sky was deep blue at the zenith. A few tattered thunderheads cloaked the monstrous sun where it touched the western horizon. Raindrops stood on every blade of grass, tiny amber pearls.
Jason had admitted that he was dying. Now I began to admit it to myself.
As a physician I had seen more of death than most people ever see. I knew how people died. I knew that the familiar story of how we face death—denial, anger, acceptance—was at best a gross generalization. Those emotions might evolve in seconds or might never evolve at all; death could trump them at any instant. For many people, facing death was never an issue; their deaths arrived unannounced, a ruptured aorta or a bad decision at a busy intersection.
But Jase knew he was dying. And I was bewildered that he seemed to have accepted it with such unearthly calm, until I realized that his death was also an ambition fulfilled. He was on the brink of understanding what he had struggled all his life to understand: the meaning of the Spin and humanity's place in it—his place in it, since he had been instrumental in the launch of the replicators.
It was as if he had reached up and touched the stars.
And they had touched him in return. The stars were murdering him. But he was dying in a state of grace.

"We have to hurry. It's almost dark now, isn't it?" Carol had gone off to light candles throughout the house. "Almost," I said.
"And the rain stopped. Or at least, I can't hear it."
"Temperature's dropping, too. Would you like me to open the window?"
"Please. And the audio recorder, you turned it back on?"
"It's running now." I raised the old frame window a few inches and cool air infiltrated the room.
"We were talking about the Hypotheticals…"
"Yes." Silence. "Jase? Are you still with me?"
"I hear the wind. I hear your voice. I hear…"
"Jason?"
"I'm sorry… don't mind me, Ty. I'm easily distracted right now. I—uh!"
His arms and legs jerked against the restraints Carol had tied across the bed. His head arched into the pillow. He was having what looked like an epileptic seizure, although it was brief: over before I could approach the bed. He gasped and took a deep lungful of air. "Sorry, I'm sorry…"
"Don't apologize."
"Can't control it, I'm sorry."
"I know you can't. It's all right, Jase."
"Don't blame them for what's happening to me."
"Blame who—the Hypotheticals?"
He attempted a smile, though he was clearly in pain. "We'll have to find a new name for them, won't we? They're not as hypothetical as they used to be. But don't blame them. They don't know what's happening to me. I'm under their threshold of abstraction."
"I don't know what that means."
He spoke rapidly and eagerly, as if the talk were a welcome distraction from the physical distress. Or another symptom of it. "You and I, Tyler, we're communities of living cells, yes? And if you damaged a sufficient number of my cells I would die, you would have murdered me. But if we shake hands and I lose a few skin cells in the process neither of us even notices the loss. It's invisible. We live at a certain level of abstraction; we interact as bodies, not cell colonies. The same is true of the Hypotheticals. They inhabit a larger universe than we do."
"That makes it all right to kill people?"
"I'm talking about their perception, not their morality. The death of any single human being—my death—might be meaningful to them, if they could see it in the correct context. But they can't."
"They've done this before, though, created other Spin worlds—isn't that one of the things the replicators discovered before the Hypothetical shut them down?"
"Other Spin worlds. Yes. Many. The network of the Hypothetical has grown to encompass most of the habitable zone of the galaxy, and this is what they do when they encounter a planet that hosts a sentient, tool-using species of a certain degree of maturity—they enclose it in a Spin membrane."
I pictured spiders, wrapping their victims in silk. "Why, Jase?"
The door opened. Carol was back, carrying a tea candle on a china saucer. She put the saucer on the sideboard and lit the candle with a wooden match. The flame danced, imperiled by the breeze from the window.
"To preserve it," Jason said.
"Preserve it against what?"
"Its own senescence and eventual death. Technological cultures are mortal, like everything else. They flourish until they exhaust their resources; then they die."
Unless they don't, I thought. Unless they continue flourishing, expand into their solar systems, transplant themselves to the stars…
But Jason had anticipated my objection. "Even local space travel is slow and inefficient for beings with a human life span. Maybe we would have been an exception to the rule. But the Hypotheticals have been around a very long time. Before they devised the Spin membrane they watched countless inhabited worlds drown in their own effluvia."
He drew a breath and seemed to choke on it. Carol turned to face him. Her mask of competence slipped, and in the moment it took him to recover she was plainly terrified, not a doctor but a woman with a dying child.
Jase, perhaps fortunately, couldn't see. He swallowed hard and began to breathe normally again.
"But why the Spin, Jase? It pushes us into the future, but it doesn't change anything."
"On the contrary," he said. "It changes everything."

The paradox of Jason's last night was that his speech grew awkward and intermittent even as his acquired knowledge seemed to expand exponentially. I believe he learned more in those few hours than he could begin to share, and what he did share was momentous—sweeping in its explanatory power and provocative for what it implied about human destiny.
Pass over the trauma, the agonized groping after appropriate words, and what he said was—
Well, it began with, "Try to see it from their point of view."
Their point of view: the Hypotheticals.
The Hypotheticals—whether considered as one organism or many—had evolved from the first von Neumann devices to inhabit our galaxy. The origin of those primal self-replicating machines was obscure. Their descendants had no direct memory of it, any more than you or I can "remember" human evolution. They may have been the product of an early-emerging biological culture of which no trace remains; they may have migrated from another, older galaxy. In either case, the Hypotheticals of today belonged to an almost unimaginably ancient lineage.
They had seen sentient biological species evolve and die on planets like ours countless times. By passively transporting organic material from star to star they may even have helped seed the process of organic evolution. And they had watched biological cultures generate crude von Neumann networks as a byproduct of their accelerating (but ultimately unsustainable) complexity—not once, but many times. To the Hypotheticals we all looked more or less like replicator nurseries: strange, fecund, fragile.
