DARPA completed the counter-signal system in June.
The engineering was elegant (Weiss's word, deployed during the briefing with the reverence of a scientist admiring another team's work). The system used the Himalayan junction's signal recording as a blueprint, generating a frequency pattern that would destructively interfere with the catastrophe signal. If the weapon fired again, if something or someone triggered the purge signal through the medium, the counter-signal system would cancel it. Noise-cancelling headphones for the sub-spacetime fabric.
The system was deployed at the farmhouse, integrated into the DEEPWELL monitoring array. A second unit was stationed at the Himalayan junction through a remote substrate interface. A third was under construction for the receiver junction.
"The counter-signal covers approximately sixty percent of the medium within the seed's architecture," Dr. K told the working group. "Full coverage requires additional units at the remaining junctions: Pacific, Siberia, Mid-Atlantic Ridge. We're manufacturing them now."
"Timeline for full coverage?" Marcus asked.
"Four months. October at the earliest."
"The relay arrives in approximately three years. We have time."
"We have time for the counter-signal. We may not have time for the machine interface. The current prototype handles data collection but can't conduct the kind of communication Sophie performs. The next iteration, the version that could potentially converse with the seed, is twelve to eighteen months away."
Sophie listened to the briefing from the DÄblin kitchen. The phone on speaker. Margaret beside her. Helen at the monitoring tablet.
Twelve to eighteen months. The machine was getting better, but slowly. The substrate's complexity resisted engineering. The emotional register, the resonance translation, the specific quality of consciousness communicating through stone. DARPA could measure the medium's properties. They couldn't replicate the human element.
"The relay will arrive before the machine can replace Sophie," Whitfield said. "If communication with the relay is needed during the arrival window..."
"Then I'll be available," Sophie said.
Margaret's hand found her arm under the table. Resting.
"The suspension is six months," Helen said. "We're in month three. The remaining three months of suspension are non-negotiable."
"And after the suspension?" Marcus asked.
"After the suspension, we reassess. Sophie's coherence, the machine's capability, the operational requirements. If Sophie chooses to resume sessions, and I emphasize *chooses*, the machine handles baseline monitoring and Sophie conducts targeted communication. Shorter sessions. Lower frequency. The machine carries the load."
"I'll choose to resume," Sophie said.
Everyone was quiet.
"I don't mean for the working group, or the NSC, or because someone asks me to." Sophie's voice was steady. The steadiness that was hers now, part of her, the composure that came from a consciousness that perceived the planet. "For the relay. When it arrives, when it's close enough to communicate in real time, someone needs to talk to it. Someone who can understand its emotional register, who can translate between human and network, who can carry the conversation that first contact requires."
"The machine..."
"The machine can measure the relay. It can't meet it." Sophie paused. "I'll meet it."

Summer in DÄblin.
The garden bloomed fully. Margaret's pansies joined by geraniums and lavender and a climbing rose that had been dormant when they'd arrived and was now covering the fence in pink blossoms. Margaret gardened every day. The physical work of tending soil and plants and the small living things that grew regardless of what happened in the sub-spacetime medium.
Sophie studied. The GCSE preparation was serious now. Margaret had arranged for a tutor to work with Sophie remotely, a retired teacher from the school in England who handled the subjects Margaret couldn't teach. Physics was Sophie's strongest subject. The tutor said she had "an unusual intuition for spatial relationships," which made Margaret almost laugh.
Helen took readings. Morning and evening. Coherence stable at twenty-three percent. Modalities stable. No progression. The plateau held.
The oscillation had settled. The medium at full capacity was stable, no longer building, no longer changing. The current flowed through the restored pathways. The scars continued to heal. The dead patches shrank. The medium was alive and working and carrying the traffic of a network that consisted, for now, of one seed, one receiver, one approaching relay, and one human consciousness connected to all of them.
Sophie could feel the relay getting closer.
The change was imperceptible daily. The distance between thirty-seven AU and thirty-six AU was imperceptible on a daily basis. But weekly, she noticed. The receiver's tracking orientation shifted by measurable fractions. The relay's signal grew marginally stronger. The seed's awareness of the approaching node intensified.
She wrote about it in the notebook, pages filling with the record of a girl watching something approach from the dark.
*June 15th. Relay at thirty-five point eight AU. The signal is stronger this week. I can perceive the two-layer pattern from DÄblin: still here, who answered. And the query layer from our experiment: what happened. Three layers now. The relay is carrying our answer, the seed's catastrophe memory, the narrative I transmitted, and processing it.*
*I wonder what the relay thinks of us. Of the answer I sent. The network was destroyed from inside. A purge. The weapon used by one part against the rest. The relay received that information six weeks ago. It's been processing it while approaching.*
*Does it know who triggered the purge?*
*I think it might. The relay was a bridge. It existed in the medium, at a junction point, connected to everything. If anyone knew the network's internal politics, it would be a relay. Bridges see all the traffic.*
*When I resume sessions, when the six months end, the first thing I'll ask the relay is: who?*
*Who decided to destroy the network?*
*And why?*

Nathan and Margaret talked regularly now.
Margaret drove to the farmhouse once a week, sometimes twice, and stood in the kitchen with her hand on the wall and talked to the man in the ground. The conversations were private. Margaret didn't share them with Sophie, and Sophie didn't ask.
But the effect was visible. Margaret was calmer. More settled. The fierce, organized energy that she'd brought to Poland had softened into something more sustainable. She still organized. She still managed. She still made lists and packed bags and bought groceries and cooked dinner. But the urgency was gone. The fear that had driven the organizing had been replaced by something else.
Trust. Margaret was learning to trust the situation. The situation, not the institutions. The husband in the ground, the daughter with the overlay, the life they were building in a rented house in Poland.
Sophie watched her mother learn to trust and thought about what it had cost. The months of crisis, the sessions, the disclosures, the conversations through walls and tables and geological medium. All of it necessary. All of it expensive. All of it leading here, to a garden in DÄblin where a woman in a sun hat grew roses.
One evening in late June, Margaret came home from the farmhouse and found Sophie in the garden, writing.
"How is he?" Sophie asked.
"Your father is..." Margaret sat on the blue bench. "Your father is learning to exist."
"He's existed for months."
"He's been present for months. Existing is different. Existing is being something, not just being somewhere." Margaret looked at the roses. "He told me he's been listening to the medium itself. The current. He says it sounds like music. Something older than human music. The medium's own voice."
"I can hear it too. The shimmer."
"He says it calms him. The first time anything has calmed him since he was human." Margaret paused. "He asked me to listen to it with him. Through the wall. Because he wanted to share it."
"Did you?"
"I put my hand on the wall and closed my eyes and listened. I can't hear the medium. I'm not connected the way you are. But I could feel the warmth. And the vibration. And..." Margaret's voice softened. The underneath voice, but warmer. "Something. Something that might have been the medium's voice, or might have been the wall's hum, or might have been my imagination. But it was there."
"What did it sound like?"
"It sounded like your father humming. He used to hum when he was reading. A tuneless thing. I'd forgotten about it until I felt it in the wall."
Sophie closed the notebook. Sat on the bench beside her mother. The garden was quiet. The roses bloomed. The geological medium hummed beneath them.
Two women on a bench in a rented garden in Poland, listening to a planet that one of them could hear and the other could almost feel, and the man who lived in the ground humming to himself the way he'd hummed when he was human and whole and too absent to notice that the women he loved were listening.
They sat until the sun went down.
