A memory rose into my mind and stuck there: a man in motion, head bent, mouth twisted into an unrelenting grimace. His eyes focused on one foot, then the other. His legs moved stiffly, carefully. His arms moved not at all. He lurched like a zombie in thrall to rigor mortis.

I knew what it was. Proprioreceptive polyneuropathy, a case study I'd encountered in ConSensus back before Szpindel had died. This was what Pag had once compared me to; a man who had lost his mind. Only self-awareness remained. Deprived of the unconscious sense and subroutines he had always taken for granted, he'd had to focus on each and every step across the room. His body no longer knew where its limbs were or what they were doing. To move at all, to even remain upright, he had to bear constant witness.

There'd been no sound when I'd played that file. There was none now in its recollection. But I swore I could feel Sarasti at my shoulder, peering into my memories. I swore I heard him speak in my mind like a schizophrenic hallucination:

This is the best that consciousness can do, when left on its own.

"Right answer," I murmured. "Wrong question."

"What?"

"Stretch, remember? When you asked it which objects were in the window."

"And it missed the scrambler." James nodded. "So?"

"It didn't miss the scrambler. You thought you were asking about the things it saw, the things that existed on the board. Stretch thought you were asking about—"

"The things it was aware of," she finished.

"He's right," I whispered. "Oh God. I think he's right."

"Hey," James said. "Did you see tha—"

But I never saw what she was pointing at. Theseus slammed its eyelids shut and started howling.

Graduation came nine days early.

We didn't see the shot. Whatever gun port Rorschach had opened was precisely eclipsed on three fronts: the lab-hab hid it from Theseus, and two gnarled extrusions of the artefact itself hid it from each of the gun emplacements. A bolus of incendiary plasma shot from that blind spot like a thrown punch; it had split the inflatable wide open before the first alarm went up.

Alarms chased us aft. We launched ourselves down the spine through the bridge, through the crypt, past hatches and crawlspaces, fleeing the surface for any refuge with more than a hand's-breadth between skin and sky. Burrowing. ConSensus followed us back, its windows warping and sliding across struts and conduits and the concave tunnel of the spine itself. I paid no attention until we were back in the drum, deep in Theseus belly. Where we could pretend we were safer.

Down on the turning deck Bates erupted from the head, tactical windows swirling like ballroom dancers around her. Our own window came to rest on the Commons bulkhead. The hab expanded across that display like a cheap optical illusion: both swelling and shrinking in our sights, that smooth surface billowing towards us while collapsing in on itself. It took me a moment to reconcile the contradiction: something had kicked the hab hard from its far side, sent it careening toward us in a slow, majestic tumble. Something had opened the hab, spilled its atmosphere and left its elastic skin drawing in on itself like a deflating balloon. The impact site swung into view as we watched, a scorched flaccid mouth trailing tenuous wisps of frozen spittle.

Our guns were firing. They shot nonconducting slugs that would not be turned aside by electromagnetic trickery—invisibly dark and distant to human eyes but I saw them through the tactical crosshairs of the firing robots, watched them sew twin dotted blackbodied arcs across the heavens. The streams converged as the guns tracked their targets, closed on two attenuate throwing stars fleeing spread-eagled through the void, their faces turned to Rorschach like flowers to the sun.

The guns cut them to pieces before they'd even made it half way.

But those shredded pieces kept falling, and suddenly the ground beneath was alive with motion. I zoomed the view: scramblers surged across Rorschach's hull like an orgy of snakes, naked to space. Some linked arms, one to another to another, built squirming vertebral daisy-chains anchored at one end. They lifted from the hull, waved through the radioactive vacuum like fronds of articulated kelp, reaching—grasping—

Neither Bates nor her machines were stupid. They targeted the interlinked scramblers as ruthlessly as they'd gone after the escapees, and with a much higher total score. But there were simply too many targets, too many fragments snatched in passing. Twice I saw dismembered bits of Stretch and Clench caught by their brethren.

The ruptured hab loomed across ConSensus like a great torn leukocyte. Another alarm buzzed somewhere nearby: proximity alert. Cunningham shot into the drum from somewhere astern, bounced off a cluster of pipes and conduits, grabbed for support. "Holy shit—we are leaving, aren't we? Amanda?"

"No," Sarasti answered from everywhere.

"What—" does it fucking take? I caught myself. "Amanda, what if it fires on the ship?"

"It won't." She didn't take her eyes from her windows.

"How do you—"

"It can't. If it had spring-loaded any more firepower we'd have seen a change in thermal and microallometry." A false-color landscape rotated between us, its latitudes measured in time, its longitudes in delta-mass. Kilotons rose from that terrain like a range of red mountains. "Huh. Came in just under the noise lim—"

Sarasti cut her off. "Robert. Susan. EVA."

James blanched. "What?" Cunningham cried.

"Lab module's about to impact," the vampire said. "Salvage the samples. Now." He killed the channel before anyone could argue.

But Cunningham wasn't about to argue. He'd just seen our death sentence commuted: why would Sarasti care about retrieving biopsy samples if he didn't think we stood a chance of escaping with them? The biologist steadied himself, braced towards the forward hatch. "I'm there," he said, shooting into the bow.

I had to admit it. Sarasti's psychology was getting better.

It wasn't working on James, though, or Michelle, or—I couldn't quite tell who was on top. "I can't go out there, Siri, it's—I can't go out there…"

Just observe. Don't interfere.

The ruptured inflatable collided impotently to starboard and flattened itself against the carapace. We felt nothing. Far away and far too near, the legions thinned across Rorschach's surface. They disappeared through mouths that puckered and dilated and magically closed again in the artefact's hull. The emplacements fired passionlessly at those who remained.

Observe.

The Gang of Four strobed at my side, scared to death.

Don't interfere.

"It's okay," I said. "I'll go."

The open airlock was like a dimple in the face of an endless cliff. I looked out from that indentation into the abyss.

This side of Theseus faced away from Big Ben, away from the enemy. The view was still unsettling enough: an endless panorama of distant stars, hard and cold and unwinking. A single, marginally brighter one, shining yellow, still so very far away. Any scant comfort I might have taken from that sight was lost when the sun went out for the briefest instant: a tumbling piece of rock, perhaps. Or one of Rorschach's shovelnosed entourage.

One step and I might never stop falling.

But I didn't step, and I didn't fall. I squeezed my pistol, jetted gently through the opening, turned. Theseus carapace curved away from me in all directions. Towards the prow, the sealed observation blister rose above the horizon like a gunmetal sunrise. Further aft a tattered snowdrift peeked across the hull: the edge of the broken labhab.
