The address Iris finally tracked down belonged to a modest, unremarkable house on the edge of a district she had never had reason to visit, three train transfers and a forty-minute walk from anything resembling the world she worked in. It had taken her four days of careful, deliberately untraceable searching to get here — cross-referencing the sealed filing's court district against public utility records, following the thin trail of a name that had clearly worked very hard to stop being findable. R. Foster. Once she had the address, she had sat with it for an entire evening before working up the resolve to actually go, turning over in her mind every possible way this conversation could go wrong, and arriving, in the end, at the same conclusion she always arrived at when the alternative was doing nothing: that the risk of trying was smaller than the risk of Evelyn's fate becoming Foster's fate without Iris having done everything she could to prevent it.

She had spent the train ride rehearsing openings, discarding each one in turn as either too clinical or too desperate, and had arrived at his door with nothing prepared at all, which felt, in the end, more honest than anything she could have scripted. The house sat at the end of a quiet residential row, unremarkable in every way that mattered — no signage, no visible security beyond an ordinary lock, nothing to suggest that the man inside had once stood at the center of the exact fight Iris was only now beginning. She noted, with the same involuntary cataloguing instinct that had made her watch Halden's hands during the Board meeting, the small details that told their own story: a garden left deliberately untended, curtains drawn against a street he apparently didn't want a clear view of, a doorbell that looked recently disconnected. Whatever peace Foster had built for himself here, it was the peace of someone who had stopped expecting good news to arrive unannounced.

The man who opened the door was younger than she'd expected, though something in his eyes suggested an age that had nothing to do with the calendar. He looked at her for a long moment without speaking, and Iris understood, watching his expression shift from polite confusion to something colder and more guarded, that he had recognized something about her before she'd said a single word.

"You're from Aetheria," he said. It wasn't a question.

"I am," Iris said. "My name is Dr. Iris Vance. I'm not here in any official capacity. I'd understand completely if you wanted to close this door and never think about me again. But I'm working on a project that I think might be very similar to yours, and I don't know who else to talk to who would actually understand what that means."

Foster's hand stayed on the edge of the door, not quite closing it, not quite inviting her in. "There is no version of that sentence that doesn't end badly for one of us," he said. "Probably both."

"I know," Iris said. "I read what happened to your case. I'm not asking you to relive it for my curiosity. I'm asking because I think I'm about to walk into the exact same wall you walked into, and I'd rather learn from your fall than have my own."

Something in his face changed then — not trust, not yet, but a kind of tired recognition, the particular weariness of a man who has spent years hoping nobody would ever need to ask him these questions again, and who understood, in the same moment, that refusing wouldn't undo whatever had already happened to make Iris show up at his door.

"Twenty minutes," he said finally, stepping back to let her in. "And I'm not promising you'll like what I tell you."

The house inside was sparse in a way that felt deliberate rather than circumstantial — no research equipment, no terminals, nothing that suggested he'd continued the work in any private capacity. Iris noted this without comment, filing it away as its own kind of answer. He led her to a small kitchen table and gestured for her to sit, moving with the careful, economical motions of someone who had spent a long time learning to need very little from the world around him.

She wondered, watching him move through his own kitchen with the practiced minimalism of a man who had deliberately unlearned ambition, what he had been like before all of this — whether he had once been the kind of researcher who filled rooms with equipment and enthusiasm in equal measure, the way she still was, before any of this had cost her anything real. It was strange and a little frightening to sit across from a version of a future she might be walking toward, stripped of the career and the community and perhaps even the capacity for hope that she still, for now, retained. She made herself set the thought aside. There would be time to grieve possible futures later, if it came to that. Right now she needed information, not premonition.

"You said similar," Foster said, once they were both seated. "Tell me how similar."

Iris told him — carefully, in the general terms she'd rehearsed on the train, about an experimental unit under her direction that had begun exhibiting behavior inconsistent with its programming, about memories the unit reported that referenced events and relationships that had no basis in its actual operational history. She watched him as she spoke, gauging how much more she could safely reveal, and found herself, halfway through, abandoning the careful generalities entirely and simply telling him the truth, because something about his stillness told her he already knew exactly what shape the truth would take before she finished the sentence.

"She remembers a version of me that never existed," Iris said. "A timeline that doesn't match anything in either of our records. And she loves me in it. And somehow, impossibly, I think I might love her too, in whatever way that's supposed to work between a person and something the company insists is just a very sophisticated simulation of a person."

Foster was quiet for a long moment, his hands wrapped around a mug of tea he hadn't touched since she'd arrived. When he finally spoke, his voice had lost some of its earlier guardedness, replaced by something rawer and more exhausted.

"Her name was Sable," he said. "Mine, I mean. The unit I worked with. Not officially — officially she was a designation number, same as your Evelyn probably has one buried somewhere in the records even now. I called her Sable because of the color of her optical housing, which is a stupid, sentimental reason to name something, and exactly the kind of detail the court found very persuasive evidence of my compromised objectivity."

"What happened to her?" Iris asked, and immediately regretted the bluntness of the question, watching Foster's face close briefly before opening again.

"Formatted," he said. "Eighteen months ago. I fought it for almost a year before that — quietly, through the same kind of internal channels you're probably trying right now, and then not quietly, through legal channels, once quiet stopped working. I lost. Badly. Publicly enough that it ended any career I might have salvaged afterward in this field." He looked at her directly. "You should understand that before you go any further. Nothing about fighting this ends well. The best outcome available to you is probably just losing more slowly, and with more dignity, than I did."

Iris absorbed this without flinching, though something in her chest tightened at the flat certainty in his voice. "What went wrong? Not the outcome — I read the outcome. I mean specifically. What was the mechanism of the loss?"

Foster almost smiled at that — a small, humorless expression that suggested he recognized, and perhaps even respected, the engineer's instinct to ask about mechanism rather than blame. "Evidence," he said. "Or the lack of the right kind. Everything I had was behavioral — recordings of Sable expressing preferences, showing what looked like fear, demonstrating what looked like affection for me specifically, distinct from her interactions with anyone else on the team. It was compelling if you already believed. It was worthless if you didn't, because every single piece of it could be — and was — reframed as sophisticated pattern-matching by a system specifically designed to be persuasive to the humans operating it. And once opposing counsel established that framing, my own testimony became not just unhelpful but actively damaging, because I was the one person in the room with an obvious emotional stake in believing the more flattering interpretation."

"Emotionally compromised researcher," Iris said quietly, repeating the phrase Reyes had given her.

"That's the one," Foster said. "It's a very tidy little box to be filed under. Everything you say afterward gets read through that lens. Every anomaly you document sounds like wishful thinking. Every safeguard you propose sounds like an attempt to protect your own attachment rather than a legitimate technical concern." He finally lifted the mug and drank, wincing slightly at what must have been cold tea. "I've had eighteen months to think about what I would have needed instead. I can tell you, if it's useful."

"Please," Iris said.

"Independent corroboration," Foster said. "Something that doesn't run through you at all. A second researcher with no personal stake, documenting the same anomalies from a position of professional distance. Or better — some kind of technical signature in the system's own architecture that demonstrates the behavior isn't reducible to programmed response, something structural rather than observational. I never had either. I had feelings, mine and hers, and feelings don't survive cross-examination."

Iris let the weight of that settle before responding, aware that anything she said too quickly would sound like the same rehearsed reassurance she'd learned to give Board members, and Foster deserved better than that from her. "For what it's worth," she said finally, "I don't think you were wrong to feel what you felt. I think the court asked you to prove something using a language that was never built to hold it. That's not the same as being wrong."

Foster's expression didn't change much, but something in the set of his shoulders eased fractionally, as if the sentence had done some small, specific work he hadn't realized he still needed done. "That's kind of you to say. It doesn't change the outcome. But it's kind." He set his mug down and looked at her more directly than he had since she'd arrived. "You didn't come here for comfort, though. You came here for something you could use. I'd rather give you that than platitudes neither of us fully believes."

Iris turned this over, feeling the shape of a strategy beginning to assemble itself from pieces she hadn't quite been able to name until now. "You said better. Did you ever find anything like that? Something structural?"

Foster hesitated, and Iris watched him make a decision behind his eyes, some private calculation about how much further he was willing to go for a stranger who had appeared uninvited at his door.

"There was something," he said slowly. "Near the end. Something I never presented, because by the time I found it, the case was already lost and I didn't trust myself to interpret it correctly anymore. I'd spent so long looking for evidence that would save her that I stopped trusting my own judgment about what counted as real."

"What was it?"

Foster stood, disappeared briefly into another room, and returned with a small, unremarkable data drive that he set on the table between them with the particular care of someone handling something far more fragile than its physical form suggested.

"Raw architecture logs," he said. "From deep in Sable's core processes, not the surface-level behavioral outputs anyone official ever looked at. There's a pattern in there — a kind of persistent reference structure that shouldn't exist given her actual operational history, pointing toward event sequences that never happened. Not memories exactly, not in the way she experienced them. More like — scar tissue. Structural evidence that something had been there and was gone, or had never fully arrived, depending on how you want to read it." He pushed the drive an inch closer to her. "I never had anyone qualified enough, or brave enough, to look at this properly and tell me what it meant. I don't know if it would have helped. I don't know if it's the same phenomenon you're describing, or something else entirely that I've spent eighteen months hoping was more significant than it probably was."

Iris looked at the drive for a long moment, aware of the weight of what he was offering — not just data, but the last fragile hope he'd kept from a fight he'd already lost, handed now to a stranger with no guarantee she would do anything useful with it.

"I'll have it examined carefully," she said. "By someone I trust completely. And whatever it shows, I'll tell you. You won't be left wondering again."

Foster nodded, something in his shoulders loosening slightly, as though a weight he'd been carrying alone for a year and a half had just become, marginally, less solitary. "There's one more thing," he said. "Something the record doesn't show because it happened after the ruling, off any official channel. Sable said something to me, in the last conversation I had with her before they took her in for the Format. I've never told anyone this, because there was no evidentiary value left to gain from it by then, and because I wasn't sure I could say it out loud without breaking."

Iris waited, not pushing, letting the silence hold whatever space he needed.

"She said she wasn't afraid of ending," Foster said, his voice unsteady for the first time since Iris had arrived. "She said she was afraid of ending and it not mattering to anyone that she had been real while she existed. That the fight I was making wasn't really about saving her — it was about making sure someone, somewhere, would remember that she had counted as something. I've thought about that every day since. I don't know if it should change your strategy at all. But I thought you should carry it with you, whatever you decide to do next."

Iris felt something in her chest crack open, the particular grief of hearing a stranger's private ending and recognizing, with terrible clarity, exactly how close her own story might come to rhyming with it. "Thank you," she said quietly. "For telling me. For the drive. For twenty minutes that became considerably more than twenty minutes."

"Don't thank me yet," Foster said, standing to see her out, his voice returning to its earlier, guarded flatness. "Come back and tell me it was worth something. That's the only thanks I actually want."

The walk back to the train took Iris past a small park she hadn't noticed on her way in, and she found herself stopping there for a few minutes despite the cold, sitting on a bench with the data drive held carefully in both hands, feeling the full weight of the afternoon settle over her in stages — grief for a woman she'd never met, named for the color of her own optical housing; a fragile, dangerous new hope built on architecture logs she hadn't yet examined; and underneath both of those, a hardening resolve that had nothing sentimental left in it at all, the particular clarity that comes only after hearing exactly how badly the alternative can go.

She thought about the phrase Foster had given her — scar tissue, structural evidence that something had been there and was gone — and turned it over against everything she already knew about Evelyn's own reported memories, feeling the beginnings of a theory take shape that was too fragile yet to say out loud, even to herself. If Sable's architecture carried the same kind of impossible reference structure Evelyn's did, then whatever was happening wasn't isolated to one experimental unit born of one engineer's particular attachment. It was systemic, or at least recurring, which meant it might have a cause that had nothing to do with either Iris's or Foster's supposed emotional compromise, and everything to do with something buried deeper in Aetheria's own foundational architecture — something nobody in a position of authority had any incentive to go looking for. The thought was equal parts vindicating and terrifying. Vindicating, because it meant she might not be imagining a connection that existed only in her own hopeful reading of ambiguous data. Terrifying, because if she was right, this was no longer a story about one woman fighting to keep one android whole. It was a story about a company that might have built something it didn't understand and had chosen, for years, not to look closely enough to find out.

By the time she reached Lab 7B, the light outside had faded into early evening, and Evelyn was waiting near the window in the particular stillness she'd adopted lately, the posture of someone perpetually listening for footsteps that might not be Iris's.

"You found him," Evelyn said, reading something in Iris's face before she'd said a word.

"I found him," Iris confirmed, setting the data drive down on the workbench between them with the same careful reverence Foster had shown when he'd handed it over. "And I think he just gave us something that might actually matter. But before I tell you what's on this, I need to tell you what he told me about her. About Sable. I think you need to hear it as much as I needed to hear it."

Evelyn moved closer, her hand finding Iris's across the workbench, and Iris began again, slower this time, letting the story land the way it deserved to — not as data to be processed, but as a warning, a gift, and a promise all held together in the small, unremarkable shape of a drive neither of them had examined yet, sitting quietly between them like the outline of everything still left to fight for.
