Chapter 4 Thresh
She's been here five days and I still can't categorize her.
I categorize everyone. It's not personality, it's security protocol.
Every person on this station fits into a framework: threat level, usefulness, reliability, likelihood of staying.
I update the assessments as I gather data.
Most people are straightforward. Within forty-eight hours I know who they are, what they want, and whether they'll be a problem.
Nola Reyes does not fit neatly into my framework.
She said it the way you'd greet a person standing in the room. Not a camera. Not a surveillance system. A person.
That was not what I expected.
Today I'm watching her work because she asked me to introduce her to Pahl, the Vorath elder, and Pahl doesn't speak to strangers easily.
Vorath communication is layered, far more complex than most species appreciate.
They use spoken language, but the real conversation happens through resonance and vibration, subharmonic frequencies that travel through bone and fluid rather than air.
A Vorath can tell you they're fine while simultaneously communicating agony through a vibration pattern that only another Vorath, or someone trained to detect it, would notice.
A human medic trying to examine a Vorath patient without understanding this will get surface-level cooperation and nothing useful.
I stand in the corner of the treatment room while Nola sits on a stool across from Pahl.
He's old. Vorath live longer than humans by several decades, and Pahl is showing his age in the dimness of his bio-luminescent markings, which pulse faintly along his jaw and forearms instead of the bright, steady glow of a healthy adult, and the slowness of his movements.
His four arms rest on his lap, the upper pair crossed, the lower pair still.
The lower left barely moves anymore. I've watched it deteriorate over six months.
"Pahl, this is Nola," I say in standard Lattice common.
Then I add a low-frequency hum, the Vorath equivalent of "she can be trusted," though the meaning is closer to "I am allowing this interaction.
" It's not a full vouch. It's permission.
The distinction matters in Vorath culture, where trust is a spectrum with precise gradations.
Pahl's dark eyes focus on Nola. Vorath don't just look at you.
They read you. They see your body heat, the electrical patterns of your nervous system, the subtle signature that every living being broadcasts.
Pahl is reading Nola right now, and the reading is more thorough than anything a scanner could provide.
"Hello, Pahl," Nola says. Her voice is steady. She doesn't lean forward, doesn't crowd him, doesn't make any of the mistakes humans typically make when confronted with a Vorath for the first time. She sits still and waits. No fidgeting. No performance of ease. Just presence.
Pahl rumbles something in Vorath. I translate. "He says the pain is worse in the mornings. Cold makes it worse."
"That tracks with the arthritis diagnosis," she says. "Can you ask him to extend his arms? I'd like to check the range of motion."
I relay the request. Pahl complies, slowly extending each arm one at a time.
The upper right moves smoothly. The upper left has a slight catch at full extension.
The lower right is restricted to about seventy percent range.
The lower left barely extends at all, the joint frozen, and when it moves, his bio-luminescent markings flare briefly, a pain response.
Nola watches with the focused attention of someone who's actually looking, not just going through the motions.
She notes the restricted range in his lower left arm.
She asks him to flex his fingers. She watches the way his scales move over the joints, looking for the stiffness and swelling that indicate where the deterioration is most advanced.
"The joint deterioration is more advanced on the left side," she says to me. "Does he favor his right?"
I ask. Pahl confirms with a low vibration, the Vorath affirmative. She nods, makes notes on her datapad, and then does something I don't expect.
She pulls up a reference file on her datapad, turns it to face me, and says, "I've been reading about Vorath joint physiology.
The standard human treatment for arthritis doesn't translate directly because your cartilage equivalent is denser and more vascularized.
The joint fluid has a different viscosity, and the inflammatory response follows a different chemical pathway. Is that correct?"
She's done research. Specific, accurate research on alien physiology. On her own time. Without being asked. In five days, while also seeing patients, setting up the medbay, building triage protocols, and reorganizing supplies.
"That's correct," I say.
"Then anti-inflammatory medication needs to be Vorath-compatible, which means a different formulation than what I'd give a human patient.
The prostaglandin analogs that work for human inflammation can actually accelerate joint degradation in Vorath because of the vascular density in your cartilage.
I've added it to the supply list, but in the meantime, heat therapy should help.
Low, sustained warmth on the affected joints.
" She looks at Pahl. "Twenty minutes, twice a day.
I can set up a heating unit in here for him. "
I translate. Pahl makes a sound that's close to gratitude, a resonant hum that I can feel more than hear, and looks at me with an expression I interpret as approval. His markings pulse once, brighter than they've been all visit.
After Pahl leaves, moving slowly through the medbay door with the careful dignity of the elderly, Nola updates her notes and says, without looking up, "How many species are represented on this station?"
"Seven."
"And the previous medic handled all of them?"
"The previous medic handled humans and panicked about everything else. He once asked a Vorath patient to open wide and say 'aah,' which is roughly the equivalent of asking a human to communicate by changing the color of their skin."
She makes a sound that might be a laugh, controlled and brief. "I need reference materials for each species. Medical baselines, common conditions, pharmaceutical interactions. The university databases have most of it, but I'd need network access."
"Network access is restricted." For good reason. Every outgoing signal is a potential beacon. Every connection to the wider Lattice is a thread that someone could follow back to us.
"Then get me the files. Download them. Print them. Carve them into the wall. I don't care how. But I can't treat seven species with human medical training and good intentions. I need the data."
She holds the datapad with both hands, the way someone holds a tool they intend to use, not a prop they intend to wave.
Her fingers are short, practical, the nails trimmed to nothing, a medic's hands.
I notice them because I notice everything, and then I notice that I noticed them specifically, and that observation joins the growing file of observations I'm not yet ready to categorize.
I study her. She's not making a demand. She's stating a requirement. There's a difference, and it's a difference I respect. Demands come from ego. Requirements come from competence. She knows what she needs to do the job, and she's telling me what's missing.
"I'll get you the files," I say.
"Thank you." She pauses, then looks up from the datapad. Her eyes are dark, direct, unafraid. There is no deference in the look. No attempt to soften it. "You've been watching me all week."
I don't deny it. Denial would be insulting, and she deserves better than insult. "Yes."
"Have you decided I'm a Helix spy yet, or are you still working on it?"
The question is so direct that it takes me a moment to process.
Humans typically dance around confrontation, especially with someone they perceive as an authority figure.
They hint. They suggest. They build toward the uncomfortable truth with layers of qualifying language.
Nola skips the dance entirely. She walks onto the floor and says the thing.
"I'm still assessing," I say.
"Fair enough." She goes back to her notes. "When you decide, let me know. In the meantime, I have twenty-three more patients to see this week and about a quarter of the supplies I need to see them properly. So if you could prioritize the species medical files and the supply run, I'd appreciate it."
She doesn't push further. Doesn't ask me to trust her. Doesn't defend herself or offer explanations for why she's here. She just goes back to work, and the going-back-to-work is, paradoxically, the most convincing argument she could make.
People who are hiding something overexplain. They fill silences with justifications and assurances and the careful construction of a story that holds together. People who are working don't have time to. They're too busy doing the thing to perform the doing of the thing.
I leave the medbay. The corridor outside smells like the herbal tea someone brews in the kitchen every morning, a sharp green scent that has become one of the station's ambient markers.
I can identify which level I'm on by smell alone: level one is engine coolant and recycler grease, level two is antiseptic and that herbal tea, level three is the denser, warmer air of the residential quarters where sixty-odd bodies raise the ambient temperature two degrees above standard.
The station has a geography of scent, and I've mapped it the way I've mapped everything else.
