We didn't talk on the way there.
Not because of anything dramatic. Just — nothing to say yet. Priya had her notebook clutched against her chest and I had my bag strap and we both had our own versions of the same problem turning over in our heads and talking would've interrupted that. The streets were empty enough that our footsteps were audible. I noticed that and then stopped noticing it.
Humid. My shirt stuck to my back inside of five minutes.
At one point she said "how far."
"Eight minutes."
She nodded. That was it.
The campus at night is a different place. Same paths, same broken light near the science block that nobody fixes, same drainage smell from the ditch that facilities has been "looking into" since before I arrived. But the quiet changes it. Makes you hear your own breathing.
Mishra's light was off. Good.
The key was on the hook, same as always, worn smooth in the grip spot from thirty years of the same fingers closing around it in the same place. There's something about that I can't quite explain. An object shaped by use. By showing up.
Inside — the smell. Chai and something burnt and underneath that something else, something that doesn't have a clean description, old and close and specific to this room.
Priya stopped in the doorway.
Just stood there. Looking at the equipment, the desk, the one window, the walls with Mishra's old proofs pinned to them, curling at the corners. I don't know what she was checking for. Maybe just — getting a feel for the room before the room did anything to her.
Then she came in and sat down.
Signal was still running.
I'd been half-convinced it wouldn't be, some stupid irrational part of my brain that had spent the whole walk here constructing the version of events where we arrived and the frequency was clean and empty and we stood here with nothing and no explanation and no way to account for the last eighteen hours of my life. But it was there. Same as I'd left it.
Priya leaned forward before I even finished pulling up the full readout. Elbow on the desk. Looking at the data with that expression she gets, the focused one, mouth slightly open, eyes moving fast.
"The second Node ID," she said.
Pulled up the margin notation. Fourth value, new, clean.
She opened her notebook to a page near the back. Old writing back there, different pen, different pressure, written a long time ago and not looked at for a while from the look of it. She put it next to the laptop.
Looked at one. Looked at the other.
Her face did nothing. Which was its own answer.
"It's Rajan's," she said.
Didn't ask how she knew. Could see it in the way she said it. Not a guess.
"You're sure."
"I watched him build his analysis. I know how he constructed his numbers." Her finger hovered over the screen without touching it. "That's his."
The dish outside moved through its automated arc. That low mechanical sound, the grind of it, the settling.
"So he's—"
"In there somewhere." Her voice was controlled but thinner than usual. Like fabric that's been washed too many times. "Two years. I kept telling myself — I don't know. I think I just stopped finishing that thought because finishing it was—" She closed the old notebook. "Difficult."
I didn't say anything.
Sometimes that's the right move.
She wiped her face quickly with the back of her hand. Annoyed at herself. Then she straightened and said "walk me through the isolation method. How you pulled the second layer."
So I did.
The whole thing. From the beginning. The prime sequence, the modifiers underneath, the four frameworks that didn't work, the moment the addressing structure finally resolved. She stopped me twice with specific questions. Technical ones. The kind with actual answers that we could both hold onto while the other stuff sat there being what it was.
This is the thing about Priya. She's — she can do both. She can be completely wrecked about something and still work. Still think clearly. I've never been able to do that. When something lands on me it lands on everything, the whole system goes down. She somehow keeps one part running even when the rest of it is in bad shape.
I found that impressive and also, in the current situation, very useful.
Forty minutes in she asked for the audio feed.
Put the headphones on. Handed her the spare pair, the older ones. She settled them over her ears and I brought up the raw channel and we just — listened. The noise. That texture. And underneath it, if you knew to listen for it, the pulse. Regular. Patient. Not asking anything. Just continuing.
Priya's eyes closed.
We sat like that for maybe five minutes. Neither of us moved.
Then she took the headphones off slowly.
"It's old," she said.
"The signal?"
"Yeah." She was looking at the headphones in her hands. "Not old like — it's not a recording. It's old like." She stopped. Tried again. "Have you ever walked into a building that's been standing for a very long time. Not abandoned. Just — old. And you can feel that it knows what it is."
"Yeah."
"Like that."
The tube light flickered. Four minutes, exact. Half second of dark, then back.
Neither of us acknowledged it.
Priya said "Akasha" quietly, still looking at the headphones.
"What?"
"There's a concept. From the Vedas." She put the headphones down. "My undergrad professor said it was metaphorical. I wrote that in my notes. Metaphorical." Something in her expression. Not quite a smile. "The medium. The substrate everything moves through — sound, light, thought. Not space. Not air. Something prior to those." She looked at the signal data. "I've been thinking about it differently since my old group."
"How differently."
"Like maybe the Rishis were doing what we're doing. Pattern recognition. Just without the equipment."
I thought about my grandmother in the kitchen saying things I didn't understand yet. "Yeah," I said. "Maybe."
I was watching the margin notation when the signal changed.
Small change. Not a new value this time. An existing one — my Node ID — with something appended to it. A qualifier. Three symbols I hadn't seen in the signal before.
Ran the decomposition. Took eleven minutes to map it against the addressing architecture.
When I got there I sat back and the chair rocked on its short leg and I grabbed the desk edge.
Priya was watching my face. She always watches faces, it's a habit she probably developed out of necessity. "What."
Turned the laptop toward her. Pointed.
She read it. Then read it again with the kind of stillness that means something has arrived and the brain is trying to find somewhere to put it.
"Status tag," she said. Slowly. Like she was feeling the words out. "A flag on the record. Something that changes the classification."
"Yeah. That's what I got too."
"What does it say."
I had it already written in the notebook. Turned it toward her.
Node 7842109381. Active Variable. Observation: ongoing. Flag: Accelerated.
She stared at the word.
Accelerated.
"When did this appear."
"While we've been sitting here."
"While we've—" She stopped. Her pen was in her hand and she wasn't writing with it. "It flagged you after I arrived. After we started working on it together." She looked at me. "It's responding to the two of us. Not just you."
"Responding or escalating?"
"There's a difference," she said. "Responding means it noticed. Escalating means it's doing something about it."
The word sat there between us and neither of us wanted to pick it up.
Her pen started tapping the desk. Three taps, stop, three taps, stop. She did this when she was close to something she didn't like. I'd seen it before but never quite like this, the rhythm of it slightly off.
"In my group," she said. Looking at the screen, not at me. "Before the first person disappeared. Meena." Tap tap tap. "She found something in her signal. A change after she brought her notes to the group meeting. She said it felt like a response." Tap tap tap. "I told her she was overreading it. That the signal wasn't—" She stopped. "She was gone three weeks later."
"Priya—"
"I told her she was overreading it." She said it again, not for my benefit, for hers. Like she'd been needing to say it out loud in a room where the signal was actually running. "I said that to her and then she was gone and I have thought about it almost every day since."
The pen stopped tapping.
The tube light was due to flicker in about thirty seconds. You can time it once you've been here long enough. I'd been here long enough.
I was watching the margin notation. Priya was writing something in her notebook. The dish outside was between sweeps, the mechanical silence of it, just the equipment hum.
The light flickered.
The monitor on the left — the one I hadn't switched on, the dark one, the one that had shown me something last night — lit up from inside.
One line. White text on black. There for maybe two seconds.
Then the tube light came back and the monitor went dark and we were both sitting completely still.
I know we both saw it because neither of us said anything for ten full seconds and the only reason you don't say anything for ten full seconds is if you're making sure you saw what you think you saw.
Priya picked up her pen. Wrote it down. Exactly as it appeared, not paraphrasing, the whole thing, the way you write something down when you don't trust your memory to hold it correctly.
She turned the notebook around.
Node 7842109381 — Accelerated. Reason: Observer count increased. Recommend: Isolation.
I read it.
Read it again.
The signal in the headphones on the desk, small and tinny from two feet away. The prime sequence just continuing. Just going. Not caring. Not stopping.
"It doesn't want us working together," I said.
Priya was looking at the word isolation. Just looking at it.
"No," she said. "It doesn't."
She closed the notebook. Put it in her bag. Then sat there with her bag on her lap and her hands on top of the bag and didn't move.
I waited for her to say something. She usually said something. She usually had the next thing, the next angle, the way of looking at a problem that reframed it into something workable.
She didn't say anything.
She just sat there in this shack in the middle of the night and for the first time since I'd known her she looked like someone who had run out of next moves. Not giving up. Just — empty. Like the thinking had gone somewhere it couldn't come back from quickly.
I didn't have anything either.
Outside the dish started its next sweep. The low grind of it, settling into position.
The monitor on the left was dark. Just a screen. Just our reflection in it — two people at a desk, a lamp, a room. Normal. Completely ordinary.
Except we'd both just been told to separate.
By something that had no mouth, no body, no address you could find on any map. Something that had been running since before any map existed.
And the thing that sat in my chest when I thought about what that meant wasn't exactly fear. It was something quieter and in some ways worse. The feeling of realising you're inside a system that has rules, and the rules don't care about you, and they were written long before you arrived.
And you've only just started learning what they are.
