He went to the detention cell at seven in the morning.
Earlier than usual. Early enough that the silver corridor was still holding the specific quiet of a building not yet fully awake — the overnight security rotation finishing their final checks, the day staff not yet arrived, the blue-white pulse of the walls running its steady rhythm into the stillness.
Rhea was awake.
Of course she was.
She was sitting on the metal bench with the cracked tablet in her lap and the stylus Alex had brought her three days ago moving across its surface — still writing, still reconstructing, still following threads from memory with the focused precision of someone who had decided that the most useful thing she could do with detention was think.
She looked up when he appeared at the barrier.
Read his face immediately.
"You found something," she said.
"Yes," he said.
He sat on the floor on his side of the barrier — the floor, always the floor, because that was the only honest geometry for this conversation — and placed Mira's tablet against the barrier's base where Rhea could see the screen.
She leaned forward.
He watched her read.
She was very still while she read.
Not the stillness of someone absorbing information passively — the active stillness of someone whose mind was running at full speed while their body held completely motionless. Her eyes moved across the data with the specific fluency of someone reading in a language they'd spent years learning — not just understanding the words but feeling the grammar, the structure, the implications beneath the surface meaning.
The Node's collection architecture.
Seven broadcast points.
The capacity timeline.
The mesh as the target.
She read all of it.
When she finished she sat back on the metal bench and looked at the ceiling for a long moment — that specific look of someone whose framework for understanding their situation has just been significantly and permanently restructured.
Then she looked at Alex.
"The university reactor wasn't the beginning," she said quietly.
"No," Alex said.
"It was the prototype," she said. "Someone built it to test the collection principle. To confirm that Void-adjacent frequency broadcasts could be stored and concentrated in a receiver node." She paused. "When it worked — when the reactor successfully broadcast to the Delta Node and the Node successfully stored the frequency — they scaled up." She looked at the data. "Seven additional broadcast points. Probably more that your engineer hasn't resolved yet."
"She's working on it," Alex said.
Rhea looked at the capacity timeline.
"Three weeks," she said.
"Yes," Alex said.
She was quiet for a moment.
"Alex," she said. Carefully. The specific quality of someone approaching a piece of information they've been carrying alone and have just decided to share. "The university rector. The one who sealed the incident files after Kola died." She paused. "His name is Professor Adewale Okafor. He's not at Lagos Technical University anymore."
Alex went still.
"Where is he," he said.
"He was appointed to the Federal Ministry of Science and Technology eighteen months ago," she said. "Special adviser on temporal energy policy." She met Alex's eyes. "Eighteen months ago. The same time the Delta Node's collection network began expanding beyond the original reactor."
The detention cell was completely silent.
Alex felt the Heartstone register the connection — not temporal energy, just the clean cold weight of two facts that had just found each other across a gap that was suddenly no gap at all.
Professor Okafor. Sealed the incident files. Moved to federal government. Eighteen months ago. Same time the network expanded.
"He's not just covering up the reactor incident," Alex said.
"He's running the network," Rhea said quietly. "Or he's working for whoever is running it." She looked at Kola's name on the cracked tablet. "Kola didn't die because of an accident. He died because someone was building something and decided three students were an acceptable cost." Her voice was steady. The scar tissue doing its work. But underneath it — something that had been cold for three years was warming into something else. Something with edges. "And that same someone has been building toward this for eighteen months. Expanding the network. Collecting the energy. Moving into government to protect the operation from scrutiny."
"Kronos," Alex said.
"Kronos's agent," Rhea said. "Or Kronos directly through a human instrument." She looked at the data. "Either way — the network isn't just a weapon. It's been running for years. It has infrastructure. It has protection." She paused. "It has a person inside the Federal Ministry making sure nobody asks the right questions."
Alex looked at her.
"Why didn't you tell me about Okafor before," he said. Not accusatory. Genuinely asking.
Rhea looked at him steadily.
"Because three days ago I wasn't sure," she said. "I had a suspicion and a timeline correlation and the specific gut feeling of someone who had been looking at the same evidence for two years without being able to prove anything." She paused. "Now I have your data alongside mine and the correlation isn't a suspicion anymore." She held his gaze. "It's a pattern."
Alex looked at the data on Mira's tablet.
At the Node's architecture. At seven broadcast points. At Professor Adewale Okafor moving into federal government at the exact moment the network began expanding.
He thought about what Kronos had said at the lagoon.
What I'm building — when it completes, no Anchor and no team of allies can stop it.
Not just temporal infrastructure. Human infrastructure. People in positions of authority making sure the operation stayed invisible. Making sure nobody sealed the reactors or investigated the Node or asked why a federal science adviser had previously covered up three student deaths at a university temporal experiment.
Patient. Ancient. Building on every level simultaneously.
"I need everything you know about Okafor," Alex said. "Every detail. Every connection you traced before the Cult found you."
Rhea picked up the stylus.
"I've been writing it for three days," she said. She looked at the cracked tablet — filled now, every panel covered in her precise handwriting. "I was wondering when you'd be ready for this part."
Alex looked at her.
"You knew this was coming," he said.
"I hoped it was coming," she said. "The moment you brought me Mira's data I knew it was." She met his eyes. "I've been waiting two years for someone with the resources to actually do something with this information." She paused. "I chose the wrong people the first time." She looked at Kola's name. "I'm choosing differently now."
Alex looked at Rhea — this twenty two year old former doctoral candidate who had been sitting in a detention cell for days reconstructing from memory every thread she'd followed toward the truth about her best friend's death — and felt the Heartstone pulse warm and steady in his chest.
Not trust. Not yet. Not completely.
But something that had been moving toward trust for days had just arrived somewhere significant.
"There's something else," Rhea said.
Alex waited.
She looked at the data one more time. At the seven broadcast points. At the capacity timeline.
"The network's collection architecture," she said. "The way the broadcast points feed into the Delta Node." She paused. "It's not just storing Void-adjacent energy. The architecture suggests it's doing something more sophisticated." She looked at Alex. "It's refining it. Processing the raw Void-adjacent frequency through the Node's systems and producing something — cleaner. More precise. More controllable." She met his eyes. "The energy that destroyed your mesh nodes. The Void-Strike."
"The Node is producing it," Alex said.
"The Node is refining the raw Void-adjacent broadcasts into weaponizable Void-Strike energy," Rhea said. "Which means the three node deletions weren't Kronos using his own reserves." She paused. "They were a test. Using the Node's output to see if the refined energy worked as a delivery mechanism."
The sub-level equivalent of silence filled the detention cell.
Alex sat on the floor and felt the cold weight of this settle into him note by note.
Not Kronos's own power. The Node's. A separate weapon system. A manufacturing infrastructure for Void-Strike energy that operated independently of Kronos himself.
Which meant—
"Destroying Kronos doesn't destroy the Node," Alex said quietly.
"No," Rhea said. "And destroying the Node doesn't destroy Kronos." She held his gaze. "They're two separate threats. Both have to be dealt with." She paused. "But the Node has a timeline. Three weeks. Kronos has been patient for four centuries." She looked at him. "Which one do you deal with first?"
Alex looked at her.
"The Node," he said.
"Yes," she said. "But not the way he wants you to." She leaned forward. "Alex — the Node's architecture has a vulnerability. Every collection network needs a synchronization signal — a master frequency that keeps all the broadcast points coordinated. If you disrupt the synchronization signal the broadcast points go out of alignment and the collection process breaks down." She paused. "The synchronization signal originates from Okafor's office in the Federal Ministry."
Alex stared at her.
"You've had this for two years," he said.
"I've had the theory for two years," she said. "I've had the proof for forty minutes." She turned the cracked tablet to face him — the last page of her reconstructed notes, written in the past hour while he sat on the floor processing the data. Frequencies. Architecture. The synchronization signal's origin point. "I needed your data to confirm the theory. Once I had it—" She paused. "The answer was there."
Alex looked at the notes.
At the solution Rhea had been carrying in pieces for two years finally assembled into something complete.
Not the Delta Node. Not a direct strike. Not walking into the trap Kronos had built.
The synchronization signal. Okafor's office. The quiet invisible thread holding the entire network together.
Cut it and the network collapses.
No Void-Strike capacity. No three week deadline. No catastrophic mesh deletion.
Without firing a single temporal shot.
He pressed his palm to his sternum.
The Heartstone beat back — warm, certain, blazing with the specific quality it had when the right path became clear.
"Rhea," he said.
She looked at him.
"When this is over," he said. "When the network is down and Okafor is facing what he's done and Kola's name is attached to the truth instead of a sealed incident file—" He held her gaze. "I'm going to make sure that happens. Publicly. On the record."
Rhea looked at him.
The calculating eyes. The something younger underneath.
For a long moment she said nothing.
Then she looked at Kola's name on the cracked tablet.
"He was studying for his quantum mechanics examination," she said quietly. "He'd been up since five. He always studied better in the library before anyone else arrived." She paused. "He texted me at six forty seven that morning. Said he finally understood wave-particle duality." A pause that was one moment longer than any previous pause in any of their conversations. "That was the last message."
The detention cell was completely quiet.
Alex looked at Rhea — really looked, past the composure and the calculation and the midnight blue hair and the intense eyes — and saw what was underneath all of it.
A twenty year old student who lost her best friend on an ordinary morning.
Who had been trying to make it mean something ever since.
"I know," he said quietly. "I'm sorry."
Rhea looked at Kola's name for a long moment.
Then she picked up the stylus.
"Go stop the network," she said. "That's what you can do for him." She looked at Alex. "Go."
Alex stood.
He picked up Mira's tablet from the barrier's base.
He looked at Rhea one more time.
She was already writing — head down, stylus moving, adding the last details of the synchronization signal architecture to the notes that had just changed the shape of the entire operation.
He walked back through the silver corridor.
Behind him the stylus kept moving.
Kola's name stayed in the first panel.
Permanent. Written with care.
Waiting to be attached to the truth.
