I wasn’t sure he believed me until he stood up and came across the room and we looked at each other, our first honest look since we had begun planning our escape. Then we were in each other’s arms, trying to say all the things we wanted to say and managing only a happy-sad incoherency. But words didn’t matter. It was enough to be able to hold him without making a lie of it. Then my hand touched the node at the back of his neck: a patch of papery skin, a fleshy bump. He flinched, and we drew apart.

He turned to Isaac. “Thank you for doing this—”

“You’re welcome.”

“—but it’s a little confusing. I knew Isaac Dvali back in the Equatorian desert. You look like him, allowing for what happened, and I know they rebuilt you from Isaac’s body. But a lot of you must be pure Vox. And to be honest, you don’t sound much like the Isaac I knew.”

“I’m not the Isaac you knew. There isn’t a word for what I am.”

Turk was looking at him with Networked attention, reading the invisible signs. “What I’m saying is, I don’t understand why you’re here. I don’t know what you want.”

Isaac’s smile disappeared and a cold light came into his eyes, a light even I could see. “It doesn’t matter what I want. It never did! I didn’t ask to be injected with Hypothetical biotechnology when I was in my mother’s womb. I didn’t ask to be cycled through the temporal Arch, I didn’t ask to be brought back to life when I was decently dead. What I wanted was never germane. It isn’t now. My neural functions are shared with processors embedded in the Network. I’m chained to Vox, I can’t exist without it, and Vox is about to be consumed by something … incomprehensible.” He made a visible effort to control himself. “The Hypotheticals don’t care about anything as trivially brief as a human life. It’s the Coryphaeus that interests them. When the Hypothetical machines reach Vox, they’ll absorb the Coryphaeus and dismantle Vox Core. Nothing human will survive.”

I said, “How do you know that?”

“I can’t talk to the Hypotheticals—I’m not what Oscar thinks I am—but I can hear them ticking out in the dark. Not their thoughts—their appetites.” His face went slack and he closed his eyes—listening, maybe. Then he shook his head and looked at Turk. “You were there when I was in pain. Not because you thought I was a god. Not because you could use me. Not like the doctors, hovering over me like crows over carrion.”

“That’s little enough,” Turk said.

“If you can save yourselves, I want to help. That’s also little enough.”

“What about you?” I asked.
