The letter arrived on official letterhead in the second week of May, addressed to Vance Research LLC rather than to Mohamed personally, a formality that struck him as more unsettling than if it had simply used his name.
"It's a courtesy notification," Elena said, reading it over the phone before he'd finished his own second pass. "The Department of Energy is formally requesting a technical briefing on the battery and solar technologies, framed as due diligence ahead of any future federal research partnership. That's the official language. What it actually means is that somebody in Washington has decided your technology is significant enough to warrant a closer look, and they're being polite enough to ask first instead of simply exercising whatever authority they believe they already have."
He read the letter a second time himself after they'd hung up, standing in his own kitchen with the same water-stained ceiling that had watched every version of this year unfold, and found that the careful, bureaucratic language somehow unsettled him more than a blunter demand would have — the specific, practiced politeness of an institution that had done this exact thing many times before and had learned, long ago, that courtesy extracted compliance more efficiently than force ever could.
"Is this connected to the calls back in January? The DOE contact from before the Journal piece?"
"Almost certainly the same office, now moving with considerably more institutional weight behind it. A research liaison making an informal call is one thing. A formal letter on department letterhead, four months later, after sixty million people watched a national profile of your work, is an entirely different scale of interest." Elena's voice carried the specific measured caution she brought to anything genuinely serious. "I'd like you and Torres in my office Thursday. This isn't a conversation to have piecemeal over the phone."

Torres arrived first, Thursday afternoon, setting a thick folder on Elena's conference table with the specific care of a man who'd already spent considerable unbilled hours preparing for a conversation he'd rather not need to have.
"I want to set expectations before Elena walks you through the substance," Torres said. "This isn't, on its own, an emergency. Companies working in strategically relevant technology get this kind of attention regularly, and most of them navigate it without incident. What matters is how carefully you navigate the next several months, because the pattern from here can go several different directions depending on choices you haven't had to make yet."
Elena took the folder, opening it to a page she'd clearly already marked. "Three things happened in the six weeks since the 60 Minutes segment aired, and I want you to understand them as a sequence rather than three separate events. First, the Department of Energy's formal briefing request, which you've seen. Second — and this one I only confirmed yesterday, through a contact who owed me a favor rather than through any official channel — the National Security Agency has opened what's internally called a threat assessment on your battery and solar technologies specifically. Not on you personally. On the technologies, and what it would mean if a foreign government acquired equivalent capability before the United States did."
"A threat assessment," Mohamed repeated, the words landing with a weight he hadn't fully braced for despite Torres's careful setup a few minutes earlier.
"It sounds more alarming than it necessarily is, and I want to be precise about that distinction. A threat assessment isn't an accusation. It's the government doing exactly what a careful board member would do — trying to understand something powerful before deciding how to relate to it. But I won't pretend the process is comfortable for the person being assessed, and I won't pretend it doesn't carry real stakes if it's handled badly." Elena closed the folder, meeting his eyes directly. "I need you to hear something plainly, Mohamed, because I think you still half-believe all of this is somehow optional. The government is paying attention now. Attention from the government isn't benign — it is the attention of a system that wants to control what it doesn't understand. That's not paranoia. That's simply what governments do with technology that could shift a strategic balance, regardless of how well-intentioned any individual official happens to be." Elena said it slowly, giving each word its own weight, the specific care of a woman delivering a line she'd clearly rehearsed because she knew exactly how much it needed to land.
"What does 'control' actually look like, in practice?"
"It could look like almost nothing — a research partnership, a few briefings, business as usual with slightly more paperwork. It could look like export restrictions on the underlying technology. In the most extreme version, and I want to be honest that this exists on the spectrum even though I don't think we're near it, it could look like classification authority being asserted over aspects of your own patents, which would be a genuinely serious constraint on how freely you could license or discuss the work going forward." Elena said it without alarm, the flat, careful accounting of a woman laying out a full range rather than predicting a specific outcome. "I don't think we're heading toward the extreme version. I think we're heading toward something in the middle, and I think the version we end up with depends heavily on how we handle the next few months."
---
"So what's the strategy?" Mohamed asked, the question he'd been holding since Torres's opening caveat.
"Engagement, not confrontation," Elena said, without hesitation, the specific certainty of a woman who had clearly been building this answer for weeks rather than improvising it on the spot. "The instinct a lot of founders have, faced with this kind of attention, is to lawyer up defensively and treat every government contact as an adversarial encounter. That instinct is usually wrong. It signals you have something to hide, even when you don't, and it forecloses the version of this relationship that actually serves you best — becoming a trusted partner the government wants to work with rather than a target it needs to monitor."
"I do have something to hide," Mohamed said, quietly. "Just not the thing they're worried about."
Elena studied him for a moment, the same recalibrating stillness he'd watched cross a dozen faces over two years. "I've suspected that for a while now. I'm not going to ask what it is. I will tell you that whatever it actually is, the strategy doesn't change. Engagement doesn't mean disclosure of everything you know. It means cooperating fully and transparently with the questions they're actually entitled to ask — how the technology works at a level that matters for national security purposes, what your supply chain looks like, who has access to sensitive specifications — while maintaining, calmly and consistently, that certain aspects of your process remain proprietary and not relevant to their legitimate interest."
"Can I actually hold that line? Or does 'engagement' eventually mean giving them everything, if they push hard enough?"
"You can hold it, as long as you hold it from the very beginning instead of conceding ground reactively once they've already learned to expect concessions. That's exactly why I wanted this conversation now, before your first actual meeting with them, rather than after you'd already improvised an answer you'd need to walk back later." Torres said it, his voice carrying the specific weight of a man who had watched other clients make this exact mistake. "We're going to prepare you thoroughly. Talking points, a clear map of what's genuinely proprietary versus what's reasonable to disclose, and a rehearsed, calm answer for the moment somebody asks you the question everyone eventually asks."
"How I actually know what I know."
"That question specifically, yes. You've handled it well with investors and reporters. Government interviewers are trained differently — more patient, more willing to sit in silence and let you fill it. We'll prepare you for that specifically, so the silence doesn't do the work of extracting more than you intend to give."

The DOE briefing happened the following week, in a conference room at the lab rather than in Washington, a small concession Elena had negotiated that she said mattered more than it sounded like it should.
"Home ground," she'd explained beforehand. "Every advantage is worth having, and comfort is an advantage, however small, especially against people trained to notice the difference between a subject who feels in control of a room and one who doesn't."
The delegation was smaller than Mohamed had braced for — two engineers and a woman named Dr. Patricia Voss who introduced herself simply as "policy," without further elaboration, and who asked, in the first ten minutes, exactly the kind of patient, unhurried question Torres had warned him about.
"Walk us through your process for arriving at the multi-junction thin-film design," she said, notebook open, pen still. "Not the result. The process."
Mohamed gave the rehearsed answer, careful and true within its own boundary — instinct, careful trial and error, a pattern of intuition he'd learned to trust over years of study he didn't fully explain the shape of. Dr. Voss let the silence stretch after he finished, exactly as predicted, and Mohamed sat inside it without filling it, the specific discipline Torres had drilled into him over two full afternoons of preparation, counting the seconds in his own head the way he'd once counted the days between one login and the next, patient in a way that had nothing to do with the technology and everything to do with two years of practice holding still under exactly this kind of scrutiny.
"That's a remarkably consistent answer," she said, eventually. "You've given some version of it to the Journal, to 60 Minutes, and now to us. I don't say that as an accusation. I say it because consistency, in my experience, usually means either a rehearsed lie or an honestly held boundary. I've read enough about your history this year to believe it's the second one."
"It's the second one."
"Good. I'm not here to strip that boundary away, Mr. Vance, whatever anyone at your company may have warned you to expect. I'm here to understand the technology's strategic significance well enough to advise my own department accurately. Your personal process is, for my purposes today, genuinely beside the point." Dr. Voss made a note, unhurried. "The engineers have technical questions. I'd like to observe those, if that's acceptable, but I won't be the one asking them."
The technical portion ran two more hours, precise and thorough, and Mohamed found it, unexpectedly, easier than the anticipation had been — pure engineering discourse, the same register he'd once brought to a folding chair and a multimeter, without any of the careful evasion the personal questions required.
The engineers wanted specifics, and specifics he could give freely. Cycle degradation curves across the first four hundred charge cycles. Thermal behavior under sustained load. The silicon anode's expansion tolerances and why the binder chemistry mattered more than the electrode geometry most competitors were still optimizing for. One of them, a man perhaps ten years older than Mohamed with the permanently skeptical expression of someone who'd reviewed a great many overstated claims, pushed hard on the manufacturing scalability — whether the process held at Panasonic's volumes or whether the published numbers came from small-batch lab conditions.
Mohamed pulled the actual production data and walked him through it line by line. The skepticism didn't vanish, but it shifted into something closer to genuine interest, which was better.
By the time the delegation left, Dr. Voss shook his hand with something that felt, if not warm, at least genuinely respectful.
"We'll be in touch," she said. "Probably more than once. I'd rather you hear that plainly now than be surprised by continued interest later."

James found him afterward, standing alone in the conference room where the delegation had just left, and studied him for a moment before saying anything.
"How bad was it, actually?" James asked. "You've got the specific look of a man who survived something rather than enjoyed it."
"Not bad, exactly. Different. Elena and Torres prepared me well — I think it went about as smoothly as it could have gone. But there's something about a government policy officer taking notes on how you answer a question that lands differently than an investor or a journalist doing the same thing."
"I imagine it would." James sat down across from him, the same conference table that had held the priorities argument nearly a year earlier, now bearing witness to something considerably higher-stakes. "I want to ask you something, and you can tell me it's not my business if it isn't. Are we going to be all right? The company, I mean. If this escalates the way Elena's warned it could."
"I don't fully know. Elena thinks engagement gives us the best odds, and I trust her judgment more than almost anyone's on this specific question. But I won't pretend to you that I have certainty I don't actually have."
"I didn't expect certainty. I've been doing this job long enough to know nobody gets that, especially not this early in a company's life." James made a note on his own pad. "Practically speaking, I'd want to know what we're committing to before we commit. If engagement means a standing briefing schedule, that's staff time and legal review every quarter, and I'd rather budget for it now than discover it later."
"Elena's drafting the terms this week. I'll have you review them before anything's signed."
"Good." James stood, the moment closing as naturally as it had opened. "Sarah wants a debrief on the technical questions, for what it's worth. She's convinced herself she could have answered two of them more precisely than the engineers accepted, and she won't rest until she's litigated the point with somebody."
"Tell her I'll take the debrief. She's probably right, knowing her."
"She's always right, knowing her. It's occasionally exhausting and consistently useful." James headed for the door, then paused. "For what it's worth — whatever this turns into, government attention or not — I'm glad I took this job. I don't say that often enough either, apparently, now that everybody around you keeps telling each other that exact thing."

He told Danielle about the meeting that same evening, the two of them on her couch, unhurried, the way they'd gotten through every hard conversation this extraordinary stretch had produced.
"The NSA," she said, testing the word slowly. "That's a different scale of attention than anything else this year, isn't it. Investors, reporters, even the government inquiries Elena mentioned after 60 Minutes — none of that was quite this."
"It's not an accusation, Elena keeps reminding me. It's assessment, not suspicion." Mohamed found himself repeating the distinction more for his own benefit than hers. "I believe her. I still felt something go cold reading that letter, in a way none of the business attention ever made me feel."
"Because this one touches the actual secret. Not just the products built on top of it." Danielle said it plainly, without judgment, the same clear-eyed honesty she always brought to the moments that actually mattered. "I've watched you carry this thing all year without ever once seeing you actually frightened by it, even after Marcus, even after the WSJ flood. This is the first time I've seen the fear reach all the way to your face instead of staying managed underneath it."
"I don't know how to keep something completely private forever from an institution with the actual authority to compel disclosure, if it ever decides it wants to."
"Then maybe the timeline you've been quietly assuming — years, someday, whenever you're finally ready — isn't entirely yours to set anymore. Not because anyone's forcing your hand yet. But because the world keeps getting closer to the door whether you open it on your own schedule or not." Danielle slid her hand into his. "I'm not saying that to frighten you further. I'm saying it because I think you needed to hear it from someone who loves you, before you hear a version of it from someone who doesn't."
"That's exactly the thought I've been avoiding all week."
"I know. That's usually how you can tell it's the true one." She was quiet a moment, turning something over before she spoke again. "Can I ask you something, and I want you to actually consider it instead of just reassuring me?"
"Go ahead."
"If the government did eventually force the question — if they compelled you to explain how you actually know what you know — would that be the worst version of this, or would some part of you almost be relieved to finally have the decision taken out of your own hands?"
Mohamed took his time with the question, the specific honesty she'd earned the right to over two years of exactly this kind of plain talk. "Both, maybe. I've spent two years being the only person managing this weight, deciding on my own timeline when and whether to ever set it down. Part of me is exhausted by that responsibility in a way I don't always let myself admit. But I don't think being forced would actually feel like relief. I think it would feel like losing the last piece of this that was ever fully mine to control."
"Then don't let it get taken from you. Whatever the actual shape of the secret is — and I still don't know, and I've made my peace with not knowing on your timeline instead of mine — I'd rather you choose the moment it becomes something other people carry too, instead of having a government agency choose it for you."
"That's easier to want than to actually execute."
"Most true things are." She smiled, the expression softening the weight of the last several minutes. "I'm not trying to solve it for you tonight. I just want you to keep it in view, instead of letting Elena's strategy and Torres's talking points become a permanent substitute for the actual decision underneath all of it."
"I hear you. I don't have an answer yet."
"You don't need one tonight. You just need to keep asking yourself the question, honestly, instead of letting the business of managing the attention become its own kind of avoidance." Danielle settled against him, the ordinary weight of her presence doing more to steady him than any of Elena's careful strategic language had managed. "Whatever happens with the government, whatever the actual timeline turns out to be — you're not carrying it alone. You haven't been carrying anything alone in a long time now, even when it still feels that way some nights."
They sat together a while longer, the television off, the ordinary quiet of two people who had built something durable enough to hold even a fear this large, and Mohamed thought that whatever the coming months actually demanded of him, he was, for the first time facing something this uncertain, not facing it from inside a storage unit with nobody else even aware he was afraid.
