Blindsight

She shook her head. "But it isn't really, is it? Any more than blindsight is really blindness. Something in your head is still taking it all in. Something in the brain is still seeing, and hearing, even if you're not—aware of it. Unless someone forces you to guess, or there's some threat. You just get a really strong feeling you should move out of the way, and five seconds later a bus drives over the spot you were standing. You knew it was coming, somehow. You just don't know how you knew."

"It's wild," I agreed.

"These scramblers—they know the answers, Siri. They're intelligent, we know they are. But it's almost as though they don't know they know, unless you hurt them. As if they've got blindsight spread over every sense."

I tried to imagine it: life without sensation, without any active awareness of one's environment. I tried to imagine existing like that without going mad. "Do you think that's possible?"

"I don't know. It's just a—a metaphor, I guess." She didn't believe that. Or she didn't know. Or she didn't want me to know.

I should have been able to tell. She should have been clear.

"At first I just thought they were resisting," she said, "but why would they?" She turned bright, begging eyes on me, pleading for an answer.

I didn't have one. I didn't have a clue. I turned away from Susan James, only to find myself facing Robert Cunningham: Cunningham the mutterer, fingers tapping against tabletop interfaces, inner eyes blinded, vision limited now to the pictures ConSensus sketched in airspace or threw against flat surfaces for everyone to see. His face remained as empty of feeling as it had ever been; the rest of his body twitched like a bug in a spiderweb.

He might as well have been. We all might. Rorschach loomed barely nine kilometers away now, so near it might have eclipsed Ben itself if I'd been brave enough to look outside. We had closed to this insane proximity and parked. Out there, Rorschach grew like a live thing. In there, live things grew, budded like jellyfish from some demonic mechanical substrate. Those lethal, vacant corridors we'd crept along, frightened of the shadows planted in our heads—they were probably filling with scramblers right now. All those hundreds of kilometers of twisted tunnels and passages and chambers. Filling with an army.

This was Sarasti's safer alternative. This was the path we'd followed because it would have been too dangerous to release the prisoners. We were so deep inside the bow shock that we'd had to shut down our internal augments; while Rorschach's magnetosphere was orders of magnitude weaker here than within the structure itself, who knew if the alien might find us too tempting a target—or too great a threat—at this range? Who knew when it might choose to plunge some invisible spike through Theseus's heart?

Any pulse that could penetrate the ship's shielding would doubtless fry Theseus's nervous system as well as the wiring in our heads. I supposed that five people in a dead ship would have a marginally greater chance of survival if their brains weren't sparking in the bargain, but I doubted that such a difference would make much difference. Sarasti had obviously figured the odds differently. He'd even shut down the antiEuclidean pump in his own head, resorted to manual injections to keep himself from short-circuiting.

Stretch and Clench were even closer to Rorschach than we were. Cunningham's lab had been kicked free of the ship; it floated now just a few kilometers from the artefact's outermost spires, deep within the folds of its magnetic field. If the scramblers needed radioactive magnetite to function, this was the most they were going to get: a taste of the fields, but not of freedom. The lab's shielding was being dynamically fine-tuned to balance medical necessity against tactical risk, as best the data allowed. The structure floated in the watchful crosshairs of our newborn gun emplacements, strategically positioned to either side. Those emplacements could destroy the hab in an instant. They could probably destroy anything approaching it as well.

They couldn't destroy Rorschach, of course. Maybe nothing could.

Covert to invulnerable. As far as we knew that hadn't happened yet. Presumably Theseus could still do something about the artefact accreting off our bow, assuming we could decide which thing to do. Sarasti wasn't talking. In fact, I couldn't remember the last time any of us had even seen the vampire in the flesh. For several shifts now he had confined himself to his tent, speaking only through ConSensus.

Everyone was on edge, and the transient had gone quiet.
