He waited until the others had eaten.
Not cowardice. Timing. Jace was doing his first post-event movement drills with Mira monitoring his class output, Dex was running the nightly perimeter check, and the Zone 7 staging area had settled into the low-hum operational quiet that Ark had learned to use for anything that needed space.
He found Sera at the edge of the area, running her thread exercises. Maintenance habit, extending and retracting, testing range, keeping the Life Weaver architecture responsive. She did it every evening like some people stretched before sleep.
"Can we talk?" he said.
She retracted her threads. Read his tone immediately. "What happened?"
"Kroft found something in her investigation. About Prometheus." He sat down on a corridor outcropping across from her. "About the human side. The translation layer between Architect engineering and the class system."
Sera was already very still.
"She identified a researcher. Someone who made contact with Architect signals two years before the Awakening. Someone who might be inside Prometheus." He held her gaze. "Dr. Elena Voss."
Sera didn't move.
That was the thing Sera did when she was frightened. Not the fast-talking, not the clarifying questions. She went absolutely still, and all the processing happened somewhere he couldn't see.
Five seconds.
Ten.
"Mom," she said.
"Yeah."
She stood up. Walked three paces away from him, stopped, walked back. "Kroft is certain?"
"She's not certain of anything. She has documentation of contact with non-human signals and a research profile that matches the technical knowledge Prometheus would need. It's strong inference."
"But it could be wrong."
"It could be wrong."
Sera put her hands on her knees and bent forward slightly, not sitting, just a posture shift that looked like she was trying to get more air. "She disappeared when I was nineteen. I was in my second year of medical training." She straightened up. "I looked. After the Awakening, when the zone records came back online, I looked for her name. Nothing."
"That matches. Kroft's files on her are encrypted and buried. She was deliberately obscured."
"Because she went underground." Sera said it flatly. Processing, not feeling. "She joined something that didn't want to be found."
"That's the inference."
"Two years before the Awakening." Her voice had gone medical-precise. Clinical distance, the same register she used when she was working a patient she couldn't let herself worry about. "So she had contact, she understood what was coming before the System activated, and she, what? Built a program around it?"
"Maybe she was recruited. Kroft doesn't know if she's leadership or deep support."
Sera looked at him. "Does Dex know?"
"Kroft told me first. I haven't told anyone else."
"You need to tell Dex." She said it without hesitation. "I'm compromised. Not in terms of loyalty, I'm not going to defect or lose operational focus. But I can't be objective about intelligence involving her. If there are decisions to make about how to approach the bridge faction, I should be excluded from those calls."
"Sera..."
"That's not me being noble. That's how it works." She held up her hand. "I joined the medical field because of her research. I thought she was dead and it still shaped everything I chose. If she's alive and inside Prometheus and the beacon in Zone 5 is a bridge to her faction—" She stopped. "I have a conflict of interest. Dex needs to know that."
Ark looked at her.
This was the thing about Sera that he still found disorienting after months: the speed with which she moved from feeling to function. She'd had thirty seconds of stillness and now she was doing security protocol analysis on herself.
"We'll tell Dex together," he said. "Tonight."
She nodded. Then sat back down on the outcropping and was quiet for a moment.
"Is she safe?" she asked.
"I don't know."
"Is she — is there any indication of her current status?"
"Kroft doesn't know where she is now. The documentation ends with the contact logs. Anything after that is Prometheus internal."
Sera absorbed this. Her hands were folded in her lap. Very controlled. "The Zone 5 beacon," she said quietly. "The bridge program's contact point."
"Yeah."
"If we reach it—"
"We don't know what's there yet."
She looked at him with an expression that was mostly steady and only slightly wasn't. "Yeah," she said. "I know."

They told Dex at 2200.
He listened to the whole briefing without interrupting. Sat with it for six seconds after Ark finished.
"Security concern," he said.
"Acknowledged," Sera said. "I self-reported."
"Not questioning loyalty." Dex looked at her directly, which was something he rarely did with anyone. "Questioning clarity. If this resolves in a direction that involves your mother, I need to know you can execute mission-critical decisions."
"I can," she said. "But I shouldn't be the one making them."
"Agreed." He turned back to Ark. "Kroft's investigation. How solid is it?"
"Four months of backtracking technical knowledge chains. She's eliminated thirty-eight other researchers. She has Elena Voss's pre-Awakening papers, her encrypted contact logs, and a three-year gap in zone records that coincides exactly with Prometheus's founding timeline."
"Not proof."
"No."
Dex was quiet for a moment. "The bridge beacon in Zone 5. If it's a communication point for the faction that wants dialogue rather than obstruction, and if Elena Voss is a senior figure in that faction, then Sera's connection is an asset, not just a liability."
"I know," Sera said.
"I'm not authorizing you to contact her. But I'm not pretending the connection doesn't matter." He stood. "New protocols: all intelligence related to Elena Voss goes through me before it reaches the wider team. Sera is read-in on operational need-to-know but I make the call on what she sees." He looked at Sera. "You object?"
"No," she said. "That's exactly what it should be."

Three zones away, Jace was testing his new capability.
He'd found a section of Void-scarred wall in Zone 7. Not active corruption, just residual. Old damage that the corridor had partially healed around. The scar tissue of dimensional spaces that had been stressed and sealed.
He called the Blade Dancer class.
The blade came darker now. Same shape, same weight in his hand. The class's kinesthetic memory was intact. But the edge was wrong in the right way, light bending around it instead of off it. The embedded corruption had changed what the class output looked like at the fundamental level.
He looked at the wall.
He put the blade through it.
Not against it. Through it. The Void-scarred section parted like the blade wasn't meeting resistance. Like it was moving through something that had already decided to let it pass.
He pulled the blade back. The wall was intact. No cut, no damage. The blade had passed through the scar tissue as if it existed in a different layer of the same space.
He dissolved the class. Stood there.
A month ago he'd have had a joke ready. He'd have turned to someone and said something about phasing through walls being great for sneaking into kitchens, or made a reference to something from the old entertainment archives, or found some way to put a frame around it that made it manageable.
He stood there in the quiet of Zone 7 with his hands at his sides.
The corruption in the Blade Dancer class was at 41% integration.
Something that had been an attack was becoming a tool.
He wasn't sure how he felt about that yet.
He wasn't sure the feeling had a name.
He turned and walked back toward the staging area, and the zone's ambient light made the edge of his shadow look darker than it should have been, and he didn't look back at the wall he'd passed through.
