The Nomad camp materialized out of the desert like a fever dream.
Leo had expected something sparse — a cluster of tents, maybe a few vehicles parked in defensive formation, the bare minimum infrastructure of people who survived by staying mobile. What he found instead was a small city in motion. Forty-odd vehicles of every conceivable size and origin formed a loose oval on a flat stretch of hardpan, connected by awnings and cable bridges and improvised corridors of salvaged paneling. Solar collectors fanned out from rooftops like mechanical flowers. A water reclamation tower rose from the center, its condensation rings catching the last of the afternoon light. Children ran between the wheels of parked crawlers. Somewhere, something was cooking that smelled of real spice.
Klem pressed her face to the crawler's narrow window like she was trying to absorb it all at once.
"How many people," she said. Not a question — a count. Her systems were probably already running it.
"Two hundred and thirty-seven," said Dara from the front. "Give or take. People come and go." She paused. "Mostly come. Helix keeps generating refugees."
Vex had woken somewhere in the last kilometer, silently and completely, the way she did everything — one moment still, the next fully present. She sat upright and studied the camp with an expression Leo was beginning to recognize as her version of overwhelmed: perfectly neutral on the surface, circuits running hot underneath.
The crawler stopped. The hatch opened.
The smell hit first — cooking fat, machine oil, woodsmoke from a real fire somewhere, the sharp green scent of hydroponic plants. Then the sound: voices in at least four languages, the clang of metalwork, music from a speaker somewhere playing something with strings.
Leo stepped out first, old habit, scanning the perimeter. Nothing threatening. Lots of curious.
Klem stepped out behind him and stopped on the top rung of the ladder, one hand on the frame, and simply looked. Her circuits pulsed slowly in long waves across her skin, silver-gold, visible even in the afternoon light. Around the camp, people noticed. Conversations paused. A few hands moved toward weapons — also old habit — and then stilled as Dara appeared and made a short, sharp gesture.
Stand down. I've got this.
"They're afraid," Klem said quietly, not moving.
"They've had reasons to be," Leo said from below her. "Give them a minute."
She gave them a minute.
It was Pell who broke the tension, because Pell was sixteen and had apparently not yet developed the instinct for caution. She pushed past Leo, grabbed Vex by the wrist, and said loudly to the assembled camp: "This is Vex. She's never had real food. Somebody fix that."
The spell broke. Not completely — there were still hard eyes and careful distances — but enough. A heavyset man near the cooking unit laughed. An older woman shook her head with the expression of someone who had given up being surprised. The children, who had no context for threat assessment, simply descended.
Within thirty seconds Vex was surrounded by seven children between the ages of four and twelve, all asking questions simultaneously. Her circuits blazed in what Leo had come to recognize as sensory overload. She looked at him over their heads with an expression of genuine helplessness.
"How do I—" she started.
"Just answer one at a time," he said. "Pick the loudest."
She looked down. The loudest was a small girl with dust in her braids who was pointing at the circuit lines on Vex's forearm and demanding to know if they were tattoos.
"No," said Vex carefully. "They are... part of me."
"Do they hurt?"
Vex considered this with complete seriousness.
"Not anymore," she said.
The girl nodded as if this were entirely satisfactory and grabbed Vex's hand and began pulling her toward the cooking unit. Vex followed, looking back at Leo with an expression he could only describe as help and don't you dare in equal measure.
He let her go.
Dara gave them a space — a converted cargo container near the camp's eastern edge, fitted with three sleeping pallets and a privacy screen. Small, functional, more than they'd had twelve hours ago.
She also gave them forty minutes, a bowl of something hot that turned out to be a grain stew with actual vegetables, and then came back with two people Leo didn't know and a look that said the social portion of the evening was concluded.
The two people were Reef and Soma. Reef was tall, gray-bearded, with the careful hands of someone who had spent years doing precise work — a former Helix systems engineer, it turned out, who had defected eighteen months ago when he was ordered to oversee the disposal of a malfunctioning Mesher unit and discovered she was still conscious. Soma was smaller, younger, with quick dark eyes and the particular stillness of someone who had been very frightened for a very long time and learned to compress it. Former Helix medical staff. She had treated Meshers in the field before she understood what she was actually treating.
They sat in the container with Leo, Klem, and Vex, and the conversation that followed was the most technically dense and emotionally strange hour Leo had spent in recent memory.
Reef wanted to know about the compliance node rupture. Klem showed him the dead spot behind her ear, and he spent ten minutes examining it with a handheld scanner, occasionally making sounds of quiet amazement.
"You did this manually," he kept saying. "From the inside."
"It felt necessary," said Klem.
"It's not supposed to be possible. The node is designed to be inaccessible to the unit's own volition. The theory was that you couldn't want to remove something you didn't know you had."
"I knew," said Klem.
Reef looked up.
"Since when?"
She thought about it.
"Since the cell," she said. "When I understood that what I was feeling was being recorded and flagged and would eventually be used to erase what I was feeling. The knowledge and the wanting to keep it arrived at the same time." She paused. "It was like being handed a key and a lock simultaneously."
Reef sat back and looked at Soma.
Soma was watching Vex with the careful attention of a physician.
"How are you experiencing the transition?" she asked. "Physically. Not in protocol language — I know you can generate a systems report. I mean what does it feel like."
Vex was quiet for a moment.
"Like interference that turned out to be signal," she said. "Like a frequency I was trained to filter that I can now hear clearly." She looked at her own hands. "The difficulty is that hearing it does not tell me what it means. I have the sensation without the vocabulary."
"That's very human, actually," said Soma.
Vex looked at her.
"Is that good?"
"I think so," said Soma. "Most of us are doing the same thing. Just with more practice."
Something in Vex's expression shifted — nearly imperceptible, but Leo was watching. A small unlocking.
After Reef and Soma left, the container was quiet.
Klem finished her stew and set the bowl aside and lay back on her pallet with one arm behind her head, staring at the ceiling. Her circuits moved slowly, the resting pulse Leo had come to find as natural as breathing.
Vex sat cross-legged on her own pallet, still processing. She had eaten half of everything placed in front of her throughout the evening with the focused dedication of someone conducting important research, and now she had the slightly stunned expression of a system running unfamiliar processes.
Leo sat with his back against the container wall, watching both of them.
"Cassius," said Klem to the ceiling.
"We'll find him," Leo said. Same as before. He meant it the same way.
"Reef might know how to reach him," said Vex. "His defection timeline overlaps with Cassius's disappearance. There may be a connection."
"Tomorrow," said Leo.
Klem turned her head toward him.
"Come here," she said.
He crossed to her pallet and lay down beside her, and she turned into him immediately, her face against his neck, one hand flat on his chest. He felt the warmth of her circuits against his skin, that low electrical hum that he had stopped noticing as strange and started noticing as hers.
"I keep thinking about the photograph," she said quietly. "The woman. Mara."
"I know."
"He died without getting back to her. He left that message for anyone, because he knew he wasn't coming back, but he still — he still wrote her name on the back. After everything." Her fingers pressed slightly harder against his chest. "I want to understand that. Why you would hold onto someone even when holding on is the last thing you can do."
Leo was quiet for a moment.
"Because they're the reason the holding on mattered in the first place," he said.
Klem processed this in silence.
Then: "Is that what I am to you? A reason?"
Leo turned his head and looked at her. The silver eyes were open and direct and entirely without artifice — Meshers, he had learned, did not do rhetorical questions. She was asking because she genuinely needed the answer.
"You're the reason I stopped counting the 72-hour survival window," he said.
Her circuits flared warm, once, like a single struck match.
From across the container, Vex spoke without looking up from her hands.
"I am also present in this conversation," she said, with dignity.
Klem laughed — a real one, loose and surprised, a sound that was still new enough to be remarkable.
"Come here then," she said.
Vex unfolded from her pallet and lay down on Klem's other side with the careful deliberateness of someone learning a new physical language. Klem shifted to make room, and the three of them lay in the narrow space with the unselfconscious closeness of people who had decided that proximity was no longer a vulnerability.
Vex took Klem's free hand.
Then, after a moment of visible internal debate, she reached across and took Leo's as well.
Her grip was precise and slightly too firm, the way everything she did was slightly too precise, slightly too much — calibrated for a world that required more force than this one.
Leo didn't say anything about it.
He just held on.
Outside the container, the Nomad camp settled into its evening rhythms — fires banked, voices lowering, the particular communal exhale of people who had made it through another day. Somewhere nearby, the girl Pell was laughing at something. Farther out, the desert said nothing, the way it always did, patient and indifferent and vast.
And somewhere to the northeast, a Helix priority signal was tightening its radius.
Forty-one hours since the cell.
Seventy-two was the record.
They were going to break it.
But not tonight.
Tonight there were three heartbeats in a metal box in the desert, two of them new to the concept, all of them choosing it anyway.
That was enough.
That was, Leo thought, closing his eyes to the warm hum of borrowed circuits and the impossible softness of a world still being invented —
more than enough.
