The lab had the quality of Hank McCoy's mind made physical — organized in ways that were internally logical and externally opaque, the surfaces covered with the productive density of ongoing work rather than the curated neatness of someone performing competence. Equipment that mixed the commercial with the custom-built, notebooks with the compressed shorthand of someone whose thoughts moved faster than standard notation could keep up with, the particular smell of a space where serious work happened consistently.
Hank looked up when Ethan came in with the expression he'd developed for these visits — the scientific attention that had been recalibrating upward ever since the holographic emitter conversation.
"I wanted to continue the Rogue discussion," Ethan said.
"Sit down," Hank said, which was both an invitation and an indication that this was going to be a real conversation.
Ethan sat.
"I've been working through what we discussed," Hank said, pulling a notebook and turning it so Ethan could see the pages of dense notation. "The contact result was unambiguous — your bioelectric aura created a barrier that her mutation couldn't penetrate. The question is whether that property can be isolated and replicated."
"And?"
Hank's expression did the thing it did when science had delivered an answer he didn't want. "The honest answer is that I don't know how your aura works. Which means I don't know what I'd be replicating." He paused. "I've tried to build things for Rogue before. Insulating materials, various field-generation devices. None of them have worked because her mutation is adaptive — it finds the biological signal through whatever barrier I construct and absorbs it anyway." He looked at his notes. "Your aura is different. It's not insulation. It's something her mutation simply cannot interface with. As if it's looking for a signal that doesn't exist in your field."
"Because my physiology operates on different rules," Ethan said.
"That's my working theory," Hank said. He leaned forward slightly, the posture of a scientist arriving at the part he found most interesting. "I'd like to run some tests. With your permission. To understand the aura better — its generation, its properties, the specific mechanism by which it operates."
They spent the next hour on it.
Hank ran the tests with the methodical precision of someone who had learned to be thorough because thoroughness was the only thing that worked. Measurements, readings, and the various instruments of the lab were applied to the field that Ethan generated without thinking about generating it. Some of the equipment produced results. Some of it produced nothing, which was itself a result.
Hank sat back and looked at the data with the expression of someone arriving at a conclusion they'd suspected and were now confirming.
"There's no way to replicate it," he said. "Not with any technology I have access to or can envision developing in the near term." He paused. "Your cells are operating on physical laws I don't have knowledge of. The aura is a product of those laws — it's not a field your body generates separately from itself. It's more fundamental than that. It's what your physiology is, expressed outward." He looked at Ethan. "To replicate it, I would need to replicate your physics. Which is—"
"Not possible," Ethan said.
"Not currently," Hank said. "Not with anything I know." He paused, and the pause had the quality of someone being honest about something that cost them something. "I'm sorry. I was hoping the new vantage would open something up."
"It might still," Ethan said. "You understand the problem better now than you did before. That's worth something."
"It is," Hank said. "I'll keep working on it. If anything changes — if I find an angle I haven't tried — I'll contact you immediately."
"Thank you," Ethan said. "For taking it seriously."
Hank looked at him with the expression of someone who had been paying attention across several weeks of interaction. "She matters to people in this house," he said. "Which means the problem matters." A pause. "Also, it's one of the most interesting problems I've ever encountered, which is its own motivation."
Ethan smiled. "I know," he said. "That's why I came to you."

He found Raven in her room on the second floor — the enhanced hearing locating her through the ambient sounds of the mansion, the specific rhythm of her that he'd been able to identify from across buildings for days now.
He knocked.
"Come in," she said.
The room had the quality of a space that had been occupied long enough to accumulate personal geography without becoming cluttered — a few books, the portrait he'd painted leaning against the wall where she could see it from the bed, the particular arrangement of someone who had made peace with where they were without having entirely committed to staying.
He sat in the chair near the window. She sat on the edge of the bed. The morning light came through at the angle it came through.
She wanted to ask something. He could tell — not from the senses exactly, more the quality of her stillness, the slight difference in her bearing that happened when she was carrying something she hadn't said yet.
He waited.
She let him wait, which was not impatience on her part but the taking of the time she needed, and he respected it, and the room was comfortable in the quiet.
"What's your opinion of Rogue?" she said eventually.
He thought about the question — not the answer, which was simple, but why she was asking it and what she was actually asking. "She seems like a genuinely good person," he said. "In difficult circumstances that aren't her fault. I like her." He paused. "What are you actually asking?"
She held his gaze. "Whether you're likely to develop feelings for other people."
He held the gaze back. "No," he said. "I'm with you."
"You say that with considerable confidence for someone who has been in a relationship for approximately three days."
"I say it because it's true," he said. "I'm not someone who does things partially. I don't — this isn't a situation where I'm keeping options open. I'm here."
She received this. Something in her expression that was not quite the warmth it would have been on another face — more the precise, particular quality of someone who was choosing to believe something because the evidence supported it and because the believing felt right.
"I appreciate that," she said. "But I want to say something too." She paused. "I've lived a long time. I've seen many kinds of relationships and many kinds of people and how they actually work over years and decades rather than weeks." She said it without judgment, just the honest weight of the experience behind it. "If you ever find yourself feeling something for someone else — tell me. Before it becomes something you're managing instead of addressing." Another pause. "I'm not saying I expect it. I'm saying I'd rather know than not know. Honesty first, always."
"Agreed," he said. "Same from you."
"Obviously," she said, with the slight edge that was one of her registers for things that went without saying.
The conversation moved. This was what it did in their company — it found its direction and went there, one thing becoming the next with the ease of people who were interested in each other's thinking.
She talked about her early years again, differently than she had on the mountain — more specific, more particular, the texture of what running had actually been like in decades he'd only read about. He listened with the full attention that he always brought to her, the kind of listening that didn't prepare responses while the other person was speaking.
And then she asked about his.
"Your parents," she said. "You haven't said much about them."
He was quiet for a moment. He thought about the story he'd constructed and how much of it was actually true and decided, as he'd decided once before, that the truest version was the right version.
"My mother passed away when I was young," he said. "My father—" he paused, "—my father I never knew well. He was gone before I could really know him." He looked at his hands for a moment. "But I've learned things about him. About what he was." He looked at her. "I trust you. So I'll tell you the actual thing."
She was still. The specific stillness of someone paying real attention.
"He wasn't human," Ethan said. "He came from somewhere else. Another world, another star — the last of his people, or near enough. He came here, and he was with my mother and—" he paused "—and then he was gone. And I'm what came from that."
She looked at him.
"The powers," he said. "The strength, the flying, the heat vision, the frost breath, all of it — it's from him. From what his people were. Earth's sun is different from the star they evolved under, and my cells absorb it differently than human cells do. That's why I keep getting stronger." He paused. "That's why I'll keep getting stronger for as long as I'm here, I think."
She was quiet for a moment. Then: "That makes sense," she said, with the precision of someone for whom a large quantity of previously confusing data had just organized itself. "It explains all of it. The telepathy immunity, the x-ray vision, the aura—" she paused. "The Ancient One says your physiology operates on different physical laws."
"Yes," he said.
"Are there others like you?" she asked. "From his people?"
"No," he said. "I'm the last."
She filed this with the careful attention she gave important things — the particular quality of something going into a significant place rather than a general one. She looked at him with the expression of someone who understood what the last of his kind meant because she had spent decades running from people who would have been glad to make her something similar.
"You should know," he said. "If we're doing this properly, you should know."
"Thank you for telling me," she said.
The afternoon moved. He told her about the Howard Stark situation — not all of it, not the Winter Soldier and the specifics of what he knew and how he knew it, but enough. A hit he had reliable intelligence about. Someone worth protecting for the future. He needed to be in the area, watching, for approximately a week to two weeks starting soon.
"Howard Stark," she said, with the expression of someone encountering an unexpected combination of words.
"The intelligence is solid," he said. "Ninety-five percent, maybe more."
"And you're going to stop it."
"That's the plan."
She considered this with the thoughtfulness she applied to things that mattered. "Be careful," she said, which was not a thing she said casually — the evidence of the weeks they'd spent together suggested careful was not a word she applied to situations she thought were actually manageable.
"I will," he said.
The day wound down the way days did in her company — with the feeling of having been fuller than its hours accounted for. He said goodbye at the door of her room rather than the front of the mansion, which was a different kind of goodbye, and she let him go with the ease of someone who knew he'd be back.

The cartel work that night went the way it had been going — efficient, informed, the map becoming more complete with each operation. He was working upward through the supply chain with the patience of someone who understood that structures needed to be properly mapped before being properly dismantled. Three more tonight, two mid-level distribution figures and one financial coordinator whose records added substantially to the picture of how the money moved.
He went home with the backpack heavier and the mind fuller and fell asleep with the specific quality of someone whose days had become very large and who was, despite this, entirely content.

Raven found Rogue in her room forty minutes after Ethan left.
The knock was the knock she used for Rogue specifically — the one that meant I'm coming in with something and you should know it's significant.
Rogue looked up from the book she wasn't reading. "Hey."
Raven sat down in the chair across from her and looked at her with the attention she reserved for things that needed addressing.
"A new variable has entered the conversation," Raven said.
Rogue set the book down. "What conversation?"
"The one about Ethan and your situation," Raven said. "Something came up today that's relevant to you. To the question of — options."
Rogue looked at her carefully. "What kind of something?"
"Something I can't fully explain yet because it isn't my information to give," Raven said. "But I want to tell you the relevant part." She paused, organizing how to say it. "Ethan has reasons — legitimate, real, not anything he chose — to need to have children. Many of them. Eventually. It has to do with who he is and where he comes from and the fact that he's the last of something."
Rogue stared at her.
"You can't be serious," she said.
"I'm not joking," Raven said.
Rogue looked at her for a long moment with the expression of someone receiving information they don't know how to file. "You're actually serious."
"Yes."
Another long moment. "So what are you saying exactly?"
"I'm saying," Raven said carefully, "that the situation is more open than it appeared. Not now. Not soon. But eventually, in the long run, if you found that your feelings developed into something real and if he felt the same, there might be a place for that conversation." She paused. "I'm not promising anything. I'm not speaking for him. I'm saying the door isn't closed in the way I thought it was when I came to talk to you in the woods."
Rogue was very still.
"I'll talk to him about it," Raven said. "When the time is right. When I know more." She paused. "But I wanted you to know that I know. And that I don't mind you — feeling what you feel. Under the circumstances, it makes sense."
Rogue looked at her gloved hands.
"Raven," she said quietly.
"I know," Raven said. "It's a lot."
"It's a lot," Rogue agreed.
She looked up. "You'd actually be okay with that? Eventually? If it came to that?"
Raven thought about this with the honest rigor she applied to important things and said, "I think so. Yes." She paused. "But they'd have to go through me first."
Rogue's expression did something complicated that eventually resolved into something that was almost a laugh. "That's very you," she said.
"I know," Raven said.
---
She lay in her own room later that night, thinking about it.
The full scope of what the last of his kind meant. The actual arithmetic of it. One person, carrying an entire genetic lineage, getting stronger every week under a sun that fueled something no one else on this planet was.
One was not enough. She understood this without needing it explained.
She thought about herself. She was not young, in the way that actually mattered, and she was not human, in the way that actually mattered, and she had a lifespan that was proving to be considerably longer than the standard model. She could do her part. She intended to.
But one was still not enough.
She turned this over with the careful practicality that decades of navigating complicated situations had given her, and arrived at the same place she'd arrived at with Rogue earlier, examined it from the other side.
Other women would be part of this picture eventually. That was simply the mathematics of it. And whoever they were — whenever that conversation happened — they would need to be people she could trust, could respect, could exist alongside in whatever shape this eventually took.
She found, examining her honest reaction to this, that she didn't mind it the way she would have expected to mind it.
What she minded was the idea of someone who wasn't right for him. Someone who didn't see him clearly. Someone who wanted a piece of what he was without understanding what he actually was.
That, she minded.
She thought: they'll have to go through me first.
She meant it with more specificity than she'd let Rogue hear. Not a gatekeeping impulse. More the bone-deep practicality of someone who had spent decades keeping things she cared about intact against a world that was not always careful with precious things.
She fell asleep with the quiet certainty of someone who had looked at a complicated thing and found they were not afraid of it.
It was, she thought, a very strange and very good feeling.
