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.
