Wren went still first.
Not the uncertain stillness of someone adjusting to a new space. Something older than that — the specific quality of attention that came from seven years of listening through walls and learning to read what sounds meant before they arrived.
Their edges flickered.
Echo noticed immediately. "What is it?"
Wren's mouth moved. The words came out slow and careful — conjugated deliberately, the way they'd been relearning language since Echo named them an hour ago.
"They're coming," Wren said. "Four. Maybe five. The corridor above."
Isaac was already moving.
"We're leaving," he said. Not a suggestion.
Maren looked up from the table. Something shifted in her expression — not surprise, she was past surprise tonight — but a rapid recalculation. The specific look of someone reassessing a timeline they thought they controlled.
"The monitoring is down in this wing," she said. "You have perhaps four minutes before they reroute through the secondary system."
"Then we have four minutes," Isaac said.
He crossed to Echo. Then to Wren. Something passed between them — not words, not resonance exactly, just the particular economy of movement that said stay close and match my pace without requiring either of those things to be spoken aloud.
Wren understood immediately.
Echo already knew.
Isaac turned toward the door.
Maren was standing in it.
She hadn't moved dramatically. Hadn't planted herself with any visible aggression. Just — there. In the frame. Hands at her sides. Notebook under her arm. The uncapped pen still in her hand like she'd forgotten it was there.
Isaac looked at her.
"Move," he said.
"In a moment," Maren said.
"We don't have a moment."
"You have three minutes and forty seconds," she said. "I need twenty of them."
Isaac's jaw tightened.
The entity pressed. Not for control — for attention. The specific pressure of something that had been listening to this conversation and had opinions about what was being calculated behind Maren's eyes.
Isaac stopped.
Not because Maren could stop him. She couldn't and they both knew it. But because the entity was right — Maren didn't do anything without reason and a woman who had spent her career three steps ahead of everyone in every room was standing in a doorway asking for twenty seconds.
That was worth twenty seconds.
"Talk," he said.
Maren looked at him for a moment. Then past him — at Echo, at Wren — and something in her expression acknowledged all three of them before returning to Isaac.
"Aldric Arclight didn't die in the field," she said.
The room went quiet.
"He didn't die of illness. He didn't die of old age." She held Isaac's blindfold directly. "He was killed. Joint operation. Bureau and Council of Seven authorization. Classified at the highest level both institutions share." A pause. "I was not involved. I want that on record even if the record is only you."
Isaac said nothing.
"He had found something," Maren continued. "About the orphanage program. About what we produced. About what the Bureau intended to do with the results." Her voice stayed measured. Unhurried. Like she was reading from her notebook rather than standing in a doorway with Bureau personnel three minutes away. "He was going to take it public. To the other cities. To the survivors beyond the walls."
She stopped.
"He came to me first," she said quietly. "To warn me. Because he thought I didn't know what the Bureau planned." A beat. "He was wrong about that. But he was right about everything else."
Isaac stood completely still.
The entity stood completely still.
"I'm telling you," Maren said, "because Lucien will find out eventually. And when he does he will need to hear it from someone who was there." She looked at Isaac steadily. "You were there. Adjacent to it at least. You were why Aldric went looking in the first place."
Somewhere above them — distant, not close enough yet — a door opened. Boots on a stairwell. The particular rhythm of Bureau personnel moving with purpose.
Two minutes.
"Move," Isaac said.
Maren stepped aside.
Not reluctantly. Not dramatically. Just — stepped aside. Like she had said what she came to say and the rest was no longer her scene.
Isaac moved through the doorway. Echo followed. Wren came last — passing Maren so closely their uncertain edges almost overlapped with her — and for a fraction of a second Maren looked at Wren with an expression that had no category in any list Echo had compiled on her face.
Not clinical. Not warm.
Something that might have been, a very long time ago, something like guilt.
Then they were in the corridor and moving.
The facility at night knew Isaac's rhythms.
He knew its.
Camera blind spots. Patrol rotations. The half second window in rune-locked doors that stuttered slightly in the presence of his entity. He had memorized all of it over five years for exactly this kind of moment — the moment when the arrangement stopped being sustainable and the only remaining option was the door.
Echo matched his pace without instruction.
Wren flickered at the edges as they moved — their uncertain geometry becoming more uncertain in motion, bleeding slightly into the corridor walls as they passed, the seven years of inhabiting infrastructure expressing itself as instinct. They weren't phasing deliberately. They were just more comfortable with walls than open space.
"Don't," Isaac said quietly.
Wren solidified. Slightly.
The boots on the stairwell grew louder.
They turned a corner — Isaac two steps ahead, Echo beside Wren, the corridor stretching toward the maintenance exit he'd identified three years ago and never used and always known he would need eventually.
Then the lights came on.
Full facility brightness — the night cycle dying all at once, every corridor flooding with white light as the secondary monitoring system finished its reroute and the Bureau finished understanding what had happened in the assessment wing.
Alarms. Low and persistent. Not the emergency klaxon of an external breach — the internal frequency that meant contained incident, personnel respond, do not alert civilians.
They were running now.
Behind them — two corridors back, closing — the sound of boots multiplying. More than four. More than five. Someone had called additional personnel the moment the secondary system came online.
Isaac didn't look back.
The maintenance exit was thirty meters ahead. Twenty. Ten.
Wren made a sound.
Not words — something between a word and a frequency, resonance and language blurring at the edges the way their physical form blurred at the edges. Echo's Fragment burns responded immediately — lighting from within, patterns blazing up both arms.
Isaac felt it a half second later through the entity.
Someone ahead.
Between them and the exit. One person. Waiting — not responding to the alarm, already positioned. Which meant they'd known. Which meant—
The figure stepped out of the shadows at the end of the corridor.
Cael Calder.
He wasn't in Bureau tactical gear. He was in his regular uniform, hands loose at his sides, the easy smile already forming on his face the way it always did — warm, agreeable, the expression of a man who liked everyone he met and meant it.
"Unit Seven," he said pleasantly. "This is quite the evening."
Isaac stopped.
Echo and Wren stopped behind him.
The boots behind them were close now. Thirty seconds. Maybe less.
Cael looked at the three of them. His eyes moved to Wren — to the uncertain edges, the Fragment burns, the evidence of seven years inside walls — and something behind his easy expression recalibrated with the particular precision of a man filing new information into existing frameworks.
"Interesting," he said softly. Almost to himself.
Then his eyes moved back to Isaac.
And his smile shifted — just slightly, just enough — into something quieter and more considered than it usually was.
"The maintenance exit is behind me," he said. "The secondary team will be at the north corridor in approximately twenty seconds." He tilted his head. "You're going to need to decide something."
Isaac looked at him.
"What do you want," Isaac said.
Cael's quiet smile stayed exactly where it was.
"To file a very interesting report," he said. "Someday."
He stepped aside.
Isaac looked at him for exactly one second.
Then he moved.
They passed Cael at a run — Isaac first, Echo, Wren — the maintenance exit ahead, the alarm behind, the boots almost at the corridor junction.
Wren passed Cael last.
And for just a moment — just a fraction of a second in the white facility light — Wren's edges shifted. Their form flickered. And what stood beside Cael for that half second wasn't Wren.
It was Isaac.
Same height. Same white coat. Same blindfold. Standing completely still while the real Isaac was already through the exit.
Cael stared.
The copy was wrong in ways that took a moment to place — the stillness too complete, the edges not quite solid, the blindfold sitting slightly differently than it should. Not Isaac. A memory of Isaac assembled from years of observation through walls and given temporary form.
The Bureau team rounded the corner.
Saw the figure in the white coat.
Hesitated.
Three seconds. Maybe four.
The maintenance exit sealed behind the real Isaac, Echo, and Wren.
The copy dissolved.
Cael looked at the empty space where it had been.
Then at the sealed exit.
Then at the Bureau team standing confused in the corridor with their weapons half-raised and no target.
He smiled — the wide easy one he wore for everyone.
"False reading," he said pleasantly. "Secondary system's still calibrating. I'll log it."
He pulled out his comm.
And began composing the most interesting report of his career.
