Kira went to the cafeteria instead of going straight up to the lab. She needed time to think.
What was the Senate planning? Part of her knew they were right, but there was still a voice in the back of her head telling her she needed to be alert. They saw the same problems she did, but their solutions were so different: Kira wanted to cure RM, but they seemed to take it as a means of maintaining control. And yes, they had very good reasons for maintaining control—the society in East Meadow was anything but solid, and the societies beyond, in the outlands, were even worse. They needed strong leadership, a strong hand to guide them.
And yet.
She closed her eyes, breathing deeply and switching gears. No more Senate—I need to get back to work.
Kira walked quickly through the halls, ignoring the bustle around her. She nodded to Shaylon, standing watch by the door, and went inside the lab. The blower hissed, the decontamination circuits buzzed in the floor, and there he was, still strapped to the table, arms extended, face to the sky, eyes dark and solemn. He glanced at her as she came in, then turned back to the ceiling.
She tapped the medicomp screen to wake it up and found the breath analysis still open; the scanner had finished its task, cataloguing thousands of different particles. Many of them it recognized, both organic and inorganic: the unusual gasses present in exhalation, fragments of shed skin cells, microscopic flecks of dirt, trace amounts of minerals, and a handful of common bacteria. Nothing special. The list of particles it didn’t recognize, on the other hand, was a dozen times longer. She expanded it, scrolling through with a tap of her finger: image after image of bizarre little chemical compounds, some big, some small, all oddly shaped and incredibly strange. She’d never seen anything like them before. As she flipped through them, she noticed that many of the images were similar, and the compounds seemed to break down into several major categories, repeated over and over. She started marking the images, studying the molecules and flagging what looked like key identifiers, separating them into subgroups, teaching the medicomp how to recognize the different pieces. Soon it was flying through the list on its own, dividing the compounds into nine major types with a tenth group of unconnected outliers. It still offered no hint as to their function, and Kira couldn’t discern one by looking at them. Whatever they were, Samm’s body was full of them.
None of the compounds were remotely as complex as the Lurker, but they still didn’t match with any substance Kira was familiar with—not fabric, not food, obviously not mineral or plastic. She looked over at him, then back at the screen, then pursed her lips and stood up. They were too common and consistent to be accidental, so they obviously had a purpose, and his body would need creation or receptor sites to take advantage of that purpose. Perhaps this had something to do with their resistance? There was only one way to find out. She walked to the table, unlocked the wheels, and started pushing it across the room. She expected Samm to ask what she was doing, but he stayed perfectly quiet.
She pulled him to a stop at the DORD scanner, a heavy machine nearly as big as some of the cars out rusting in the parking lot. This was the big gun in her laboratory arsenal: a medical scanner that could catalog an entire body, layer by layer and piece by piece. She hit a switch to turn it on, then crossed back to the medicomp while it booted up. The definitions she’d created for the categories of compounds were still there, along with several of the clearest images, and she froze them to the screen before sliding the screen out, disconnecting it from the medicomp, and carrying it carefully to the DORD. The screen had an impressive amount of computing power all on its own, but it was nothing compared to the sensor systems it could attach to. She slid it into the DORD, hearing the click as it locked into place, and a few quick finger taps later the machine was ready to go. The DORD would scan Samm’s lungs, throat, and nasal passages for anything resembling the mysterious compounds, which would give her a good idea of where they came from and where they went. She’d have to intuit the rest from there. Kira raised the sensor array, swung it out, and centered Samm beneath it; it was a thick, heavy piece of equipment in a white plastic shell, easily the heaviest thing in the room, but it held its own weight perfectly. She tapped start, and the DORD whirred to life.
Kira watched the screen closely, eager to see what the scan turned up. It was not a quick scan. She drummed her fingers nervously on the DORD housing, then turned and walked to the window; she wanted to ask Samm if he knew what the particles were, despite his refusal to talk, but now that the scan had started, any significant motion would upset it. She turned again and watched him, steady as a rock, almost as if he were holding still on purpose.
She saw motion on the screen and ran to check it; the DORD was already displaying and categorizing some preliminary images. She flipped through the list and opened one for the compound labeled M, a funny little horseshoe-shaped particle. The DORD had found several structures in Samm’s body that it thought might be related to it: one in the nasal cavity and the rest in the lungs. Kira pulled them up, side by side on the screen, and studied them; they looked almost like glands, though not any glands Kira was familiar with. The one in his sinuses was significantly larger, and the DORD had cross-linked it to several other files. Kira opened the list and flipped through it quickly, mildly surprised at what she saw; the DORD had linked that image to every compound it had scanned for thus far. They each had a little gland of their own in the lungs, but they were all connected to the big one in his head.
Kira studied the gland closer while the DORD kept working. What did it do? She couldn’t just ask the computer to guess, but she could ask it to search its database for partial matches. She started the search and looked back at the image again, buckling down for another long wait, but the results were almost instantaneous: no match. She frowned and ran the test again. No match.
Guess I’m going to have to do this manually. Given that each particle had two related structures, the obvious first guess was that one structure created the particle and the other one caught it: a writer and a reader. Which implied that they carried information. She ran another search, this time looking for anything in the database that wasn’t human. The DORD found an old file, pre-Break, where somebody had scanned a dog, and she asked the computer to look for partial matches in there. One popped up almost immediately, displaying a structure remarkably similar, though far simpler, than the one in Samm. It was a vomeronasal organ.
Samm had an incredibly sophisticated pheromonal system.
Kira pulled up more files, reading what she could on pheromones: They were a system of simple chemical communication, like a form of smell but far, far more specialized. Insects used them for simple things like marking trails or warning one another of danger; dogs used them to claim territory and to signal breeding times. What did the Partials use them for?
I may as well try asking, she thought. “Tell me about your . . . pheromones.” Predictably, Samm said nothing. “You have a highly developed system of chemical synthesizers and receptors; can you tell me about it?”
No response.
“Can’t blame me for trying.” She thought a moment, looking around the room, then opened the medicomp and pulled out the rubber glove Samm had breathed into. She brought it near his face, pricked it with a pin, and squeezed it as hard as she could, propelling the air directly into Samm’s nose. He coughed and spluttered, jerking his head to get out of the stream of air, but Kira watched in wonder as his demeanor seemed to grow more calm—his heart rate rose as he reacted to the forced air, then fell again almost immediately as he reacted to . . . something else. The pheromones. His eyes relaxed, his expression softened, his breathing became more even.
He seemed, Kira thought suddenly, like he was making exactly the same face he’d made in the morning, when he’d agreed to blow into the glove.
“Kuso,” he said. “That’s not fair.”
Kira put her hands on her hips. “What just happened?”
“You’re using my own data against me, and now I—damn it.” He closed his mouth and looked at the
