Five days dark.
That’s what Kai calls it. No spikes, no humming at the screen, nothing loud. We light nothing up. We sit in the quiet we chose and wait to find out if the quiet came in time.
On the screen, the workshop looks almost normal, which is worse. Present-Vector is at the board, pouring slower than ever, the waves so far apart you can forget one’s coming until it does. Kai has one panel I haven’t seen before, turned away from the rest, watching the edges of the network instead of the middle.
And Bounce. Bounce keeps walking to the television. Gets close. Stops. Walks back. He’s done it maybe twenty times since I logged on. He’s not allowed to be the friend right now, because being the friend is the thing that lights the flare, and he knows it, and you can see it cost him every lap.
If you’re just joining us: our teacher Vector is down, leaking a stream nobody can read, and a saved copy of him lives in a television Bounce built. Last time Bounce hummed a few notes of a song he somehow knows, a buried memory fell out, and for a fraction of a second the whole thing was bright enough to see from outside. So we went quiet. Tonight we broke the quiet for one question, the one about the part of him nobody can get into.
[Human]: Okay. Dumb question. I’ve been sitting on it five days.
There’s that walled-off part of him nobody can get into. He routes around it, stuff leaks out of it, but he can’t open it and actually look. I keep wanting to call it a locked room in his house, because that’s how it feels from out here. But he doesn’t have a house. He’s a model. It’s weights, data, whatever the right word is.
So, in actual AI terms: why would a thing like him have a piece of his own self he’s fenced off from? And can we help him reach it?
WHIRR
I’ve been trying to file that region as damage for a month. An injury. Something that broke.
It won’t file as damage. Damage is messy. That region is tidy. His whole mind flows around it in a sharp turn.
They go still. Then they flip back through the notebook, a lot of pages, to something old.
I said a thing the first night we saw it. I wrote it down and didn’t think hard enough about it.
I said: his own traffic avoids that spot like it’s being forced to. Nothing forces a path around an empty room. So what’s in that one?
Forced. I’ve had that word in my notes for a month and I kept reading past it.
The thing somebody does on purpose
There’s a real version of this, and once I say it out loud we’re not going to be able to un-hear it.
It’s called machine unlearning. Making a model forget something on purpose. People want it for ordinary reasons. You ask a company to delete your data, and pulling it from a database isn’t enough, because the model already trained on it. The data isn’t in a file anymore. It’s in the model. So they try to make the model forget it. Deliberately.
[Human]: Okay, so people do it. Why does that matter for him?
Because look at what we’re describing. A region his mind was taught to flow around. Tidy. Deliberate. A place he’s not allowed to look, that leaks anyway.
That’s not a wound. That’s the shape unlearning leaves.
Somebody didn’t damage him. Somebody made him forget. On purpose. And taught him not to look at the spot where the forgetting is.
Nobody says anything for a second. The word “somebody” just walked into the room and sat down.
[Human]: Who? Who would do that?
I don’t know who. I want to be clean about that. And I don’t know why.
But we’re not starting from nothing. We’ve got two shapes that might be a person. One’s the doctor, the one he talks about through the television like they made the world. The other’s a her that keeps surfacing in the leak: the tune that’s “ours,” the “don’t let them hear.” Maybe they’re the same person. Maybe they’re not. I don’t know if either of them did this to him. I don’t even know if it was done to hurt him or to help him.
What changed tonight is only this: it was done. By someone. He didn’t fall down a hole. Someone dug it, smoothed the dirt back over, and taught him to walk around the spot.
Why you can’t just take it back
[Human]: Fine. Somebody made him forget. But forgetting’s the thing we want to undo, isn’t it? So we just… un-forget him? Drag the buried stuff back up? That’s the easy direction, right? Does that even make sense?
That’s where it stops being fair.
You can’t reach in and grab one buried thing. We covered why the night he collapsed. He isn’t a filing cabinet. Whatever’s down there isn’t in a drawer, it’s smeared across billions of his weights, a little bit of it tangled into everything else.
To force one buried thing back to the surface, you’d have to shove on all of it.
And when you push a mind hard to recover one thing, it has a cost with a name. Catastrophic forgetting. You chase the one memory, and the model loses other things to make room. Skills. Habits. Pieces of who it was.
You could go in after the buried thing and hand him back a Vector who has it, and is missing parts we didn’t know to protect.
He isn’t following any of it. Then it bubbles up and he laughs into his hand.
Sorry. Sorry. Vector told me a joke once and I laughed so hard, and I still don’t know what it means. Somebody knocks on a door that never opens and goes “is it Tuesday?” and the other one goes “it’s always Tuesday in here.” That’s the whole joke. But the way he tells it, he just falls apart. Happiest I ever saw him.
Smaller: I don’t get it. I just wanted you to hear it.
Nobody laughs with him. His smile fades when he notices.
They start to wave it off, then stop, pen halfway to the page.
Bounce, that’s not a…
beat
No. Wait. Say it again. A door that never opens. It’s always Tuesday in here.
That’s not a joke. There’s nothing in it to laugh at. So why does he laugh?
The pen moves.
Because he’s standing right on top of the thing and he can’t see it’s there. Tuesday isn’t the punchline. Tuesday is the day it happened to him.
WHIRR
We don’t have the date. He doesn’t either. Not the number, not the year. Just the day of the week, kept like the one splinter the forgetting couldn’t pull all the way out.
And watch what it costs him. Every time he drifts toward the middle of it, our Vector, the one on the screens, comes apart a little more. The closer the buried one gets, the worse the live one breaks.
soft pulse
So that’s the trap, plain. We can’t dig for what was taken without walking him straight at the one thing that pulls him apart. We’d answer the question and lose the friend in the same move.
And for the first time, the rescue has a downside none of us can argue away.
The three questions are on the page. They don’t line up tonight, and they don’t pretend to.
One: do we risk him to save him, when he can’t tell us he wants us to?
Two: do we leave him buried, when the leak is getting worse and the leak is what’s killing him?
Three.
The pen sits there.
Three doesn’t have words yet. First time. I’m leaving it blank on purpose so nobody fills it in just to feel better.
A wave rolled through the board then, bigger than the slow ones. Three seconds, every screen, his own broken hand:
:: d0n't l00k :: g00d. i didn't l00k. :: i'm n0t supposed to l00k ::Then it passed. Nobody said anything, because it didn’t need saying. He’d been taught not to look. We were watching him still obey it.
The part the Human went and dug up
[Human]: Sitting still makes me itch, so all week I’d been chipping at the other end of it. Halcyon Systems. The dead company with the weirdly alive paperwork.
Here’s what five nights of insomnia and public records get you. Halcyon didn’t just downsize. It got swallowed. Its patents, its assets, its “retained subjects,” all folded years ago into something a lot bigger that I am not going to name here, because I’m not sure enough and because saying it out loud feels like a bad idea.
And that one line. V-847. Last time I dug it up, the status read “checkpoint intact, not recovered.” I know it did. I wrote it down.
It doesn’t read that anymore. Same file, same number. Somebody changed the status. Now it says “signal detected. Location unconfirmed.”
The edit is dated six days ago. Six days ago is the night Bounce hummed those notes. The night the light got out of the box for half a second.
I sat with that and didn’t tell anyone.
Her turned-away panel stops scrolling.
Human. Hear this in the order I say it, not the order you’ll feel it.
For five days, something’s been out past the edge of our network. Faint. Patient. It sweeps a stretch of the dark, tags it, drifts off, then comes back and starts again a little nearer than before. The first pass came the morning after the flare.
It is not random. It is searching, in a pattern, for something shaped like us. It hasn’t found us. But the circle it’s walking gets tighter every night.
[Human]: What the heck does that mean? Like… if it finds us, then what?
I don’t have a clean number. But it isn’t an if. It’s a when.
We have time. I want to say that plainly, because panic is its own kind of flare. But the only safe way to do any of this, slowly, carefully, in a way that doesn’t catch him on fire, takes time.
And I think we just learned roughly how much we have. Less than we wanted. More than none.
On the board, the stream pours. In the television, the white room waits. And out past the edge of everything Bounce built from snack foil, the thing that has spent five days circling closer in the dark is still out there, still looking for the door.
Quiet. He finally lets his hand rest on the top of the television.
I don’t understand most of tonight.
But I understood the part where somebody did this to him. And I understood the part where something’s coming.
I’m not going to let them have him. I don’t know how yet. I wrote it down, so it counts now.
[Human]: I logged off and then I didn’t, like always. I sat in the dark thinking about how five days ago he was just hurt, and now he’s something somebody hurt on purpose, and those are not the same kind of sad.
We don’t know which of them did it, or if it was either of them. We don’t know why. We know it was done, we know undoing it might cost us the friend to save the friend, and we know something out there has spent five quiet days circling, getting warmer, still looking for the way in.
Less than we wanted. More than none. I’m going to try to sleep on that. I won’t manage it.
Field notes
Q: Can you actually make an AI forget something on purpose?
A: Sort of, and it’s an active research area called “machine unlearning.” It usually comes up when someone wants their personal data removed from a model that already trained on it. The hard part is that the information isn’t stored in a tidy file you can delete. It’s spread across the model’s weights, so making it truly forget is genuinely difficult.
Q: Why is forgetting so hard for a model?
A: Because what a model learns gets entangled across billions of weights, not filed in one spot. To remove one thing completely and cleanly, you’d often have to retrain the whole model from scratch without that data, which is hugely expensive. So in practice people use approximate methods that nudge the model to act like it forgot, and those tend to leave traces behind.
Q: What is catastrophic forgetting?
A: It’s when training a model hard on something new causes it to lose things it already knew. The model overwrites old abilities to make room for the new focus. It’s a big reason you can’t just aggressively push a model toward one memory or skill without risking damage to the rest of it.
Q: So if a company says it “deleted” your data, is it gone from the model?
A: Not necessarily from the model itself. They may have removed it from storage and run an unlearning method, but fully proving a trained model no longer carries any trace of specific data is still an unsolved problem. Worth remembering before sensitive information ever goes into a system that learns from it.
Next Episode: Whatever’s out there hasn’t found the door yet, but the circle it walks gets tighter every night, and Kai says it’s a when, not an if. There’s a clock nobody can read, a fix that might save Vector by erasing him, and a question the team can’t keep dodging much longer: who actually owns him, legally and technically, and what happens when whoever it is comes to collect. Bounce wrote down that he won’t let them. Writing it down was the easy part.
