The Helix-7 joint research station orbited a brown dwarf at the edge of the Concordat boundary, which meant it received resupply once every nine weeks and had the particular atmosphere of a place that had decided, out of necessity, to be interesting rather than comfortable.
Dr. Zara Lennox was twenty-seven years old and had been posted there for fourteen months, which was twelve months longer than her original assignment and two months longer than she'd been willing to explain to her supervisor on Earth. The extension request had cited the ongoing signal project. Both she and her supervisor understood this was only partially true.
The other part was Kaen.
He was Orrivan—tall, pale-complexioned, with the characteristically amber eyes and the low bioluminescence along the temples that Orrivan biology produced under certain conditions, most of which the xenobiological literature categorised as heightened emotional states. He was the Concordat's senior envoy on Helix-7, assigned to the joint signal project six months ago, and he had a quality of attention that Zara had spent six months failing to acclimatise to. He listened to everything. He remembered everything. And he had been looking at her, since the first week, in a way that the Orrivan literature described as resonance—an involuntary empathic alignment to a specific individual—and which the literature also specified was extremely rare.
She had read the literature. She had not mentioned it.
On the night of day four hundred and thirteen, at 2:17 in the station morning, the signal broke.
It was Zara who found it—a recursive pattern in the tertiary frequency band that they'd been treating as interference for three months, which was not interference at all but the cipher key, embedded in the signal itself the way a biological organism embedded its own repair instructions. She pulled Kaen from his quarters with a message that said only come now, and he arrived in the communications lab in three minutes, dressed, and looked at what she'd found.
For a long time he didn't say anything.
Then: "You found it in the interference band."
"It was always in the interference band. The signal is its own key." She turned from the console and looked at him. "We've been trying to decode something that was trying to decode us back."
His eyes, in the blue-lit lab, were the specific amber that the literature noted as non-baseline. The bioluminescence at his temples was visible—slow, steady, the particular pattern she had spent six months cataloguing without quite admitting she was cataloguing it.
"The source coordinates are in the header," she said. "I ran the triangulation. It's a system seventy light-years from here. No station, no known settlement. The signal is—old, Kaen. Centuries old. Someone sent this and has been waiting."
"I know." He was looking at her rather than the console, which was not his usual practice when there was new data. "Zara."
"It's in the secondary encoding layer—"
"I know what's in the encoding layer. I read it in the first ten seconds." He crossed the lab to the console beside her and stood close—the specific proximity that the Orrivan literature called proximity comfort, the involuntary narrowing of distance to a resonance anchor. She had noted it. She had been noting it for six months. "I need to tell you something. I've been trying to find the correct timing, and there is no correct timing, so I'm going to say it now because we've just broken a centuries-old cipher and the moment seems appropriate."
She turned to face him fully.
"I have been able to feel your emotional state since the third week of our collaboration," he said. "This is not unusual for Orrivans in prolonged contact with non-Orrivan colleagues. What is unusual is the specificity. I don't feel your emotions as ambient data. I feel them the way I feel my own." He held her gaze steadily. The bioluminescence at his temples pulsed once. "I am aware this is a disclosure you did not ask for and may not welcome. I wanted you to know."
Zara looked at him. "You've known how I feel."
"Yes."
"For six months."
"Yes."
"Including—" She stopped. Started over. "What have you known?"
He was quiet for one moment—the particular quiet of an Orrivan managing a disclosure—and then said, with precision: "That you're interested in me. That you read the resonance literature after the third month. That you find our work together the most satisfying thing you've done professionally. And that on several specific occasions, when you thought I wasn't paying attention, you were." A pause. "I find I could not in good conscience allow the signal to break and not tell you, in the same breath, what I know and what I haven't said."
The station hummed. The brown dwarf outside the lab's porthole produced its dull amber light. The signal's source coordinates sat on the console between them, seventy light-years away and several centuries patient.
"What do you feel now?" Zara asked. "Right now."
The bioluminescence at his temples deepened to a slow, steady pulse. "Anticipation," he said. "And something I don't have a precise Orrivan term for. The closest human approximation I've found is hoping."
She reached up and touched the bioluminescent trace at his temple—a question, a data point, the decision she had been not-making for six months. His eyes went very still.
"What does that feel like?" she said.
"Like the interference band," he said, which she understood immediately, because she had spent three months thinking the signal was noise. "Zara."
She kissed him.
He responded with a completeness that the literature had not prepared her for—not tentative, not calculating, but full and immediate, the resonance anchor and the resonance subject arriving simultaneously at the same conclusion. His hands found her face, her waist, and she gripped the front of his uniform and felt the warmth of him, genuinely warm, the bioluminescence spreading in slow arcs across his temples and down the side of his neck.
He walked her backward until the lab's far console caught them, and she pulled him closer, and his mouth was at her throat and then at her ear saying her name in Orrivan, which she had never heard him do, and it was the most interesting piece of linguistic data she had collected in fourteen months on Helix-7.
She worked his uniform open and he worked hers in return, and the blue lab-light went on burning, and she pressed her hands to his chest and felt the warmth of the bioluminescence on her palms—brighter at her touch, which the literature described as amplification feedback, which she had spent three months pretending she hadn't thought about. He pressed her back against the console and his hands found their way to her hips, the hem of her trousers, and she said his name and meant it completely and stopped cataloguing.
He put his mouth where his hands had been, thorough and specific, and she gripped the console edge and looked up at the porthole and the dull amber light and stopped being a scientist for the first time in fourteen months. When she pulled him back up and looked at him—amber eyes bright, bioluminescence blazing at his temples and his throat—and said now, he understood her without translation, and pressed into her with the same focused attention he brought to everything that mattered.
He moved with the unhurried deliberateness of someone who had waited six months and was not interested in rushing. She held his shoulders and felt the bioluminescent lines shift and brighten under her hands, responsive, alive—and stopped caring about the literature's categorisation of anything and simply let herself feel it. She came against him with his name in her mouth and her face in the crook of his neck and the signal still open on the console behind them, and he followed shortly after, his breath ragged, the bioluminescence blazing steady and bright.
In the specific quiet of the Helix-7 communications lab at 3:04 station morning, the signal waited patiently on the console, several centuries accustomed to patience.
Zara pulled her uniform back into place and looked at the source coordinates. "Someone sent this and has been waiting for an answer."
"Yes." Kaen stood beside her, his uniform settled, the bioluminescence at his temples slowly returning to baseline—except, she noted, for the faintest residual trace that the literature marked as bonded resonance persistence. She had read that passage multiple times. "What do you want to do?"
She looked at the coordinates. Seventy light-years. No known settlement. A signal that had been patient for centuries.
"We answer," she said. "And then we go."
He turned to look at her. The residual bioluminescence pulsed once, warm.
"Together," she said.
"Together," he agreed, and began composing the reply.
