The inside of Xavier's mansion had the quality that Ethan had half-expected and was still slightly unprepared for — the specific combination of institutional and personal that came from a building being simultaneously a home, a school, and a headquarters for something that didn't have a clean public name. The hallways were wide, the ceilings high, the woodwork the kind that suggested the original construction had been done by people who expected it to last. Framed photographs on some of the walls, a trophy case near what appeared to be a common room, the distant sound of something that might have been a Danger Room running through its automated cycles somewhere below.
He followed Xavier through the entrance hall with the conscious effort of someone maintaining an appropriate exterior over an inappropriate interior.
These are the X-Men, said the interior. You are walking through Xavier's mansion with the actual X-Men, and Charles Xavier is right there.
Yes, said the exterior. Very interesting. Keep walking normally.
The group that had come outside to meet him had redistributed on the way in — Scott and Bobby had peeled off at the first corridor junction with the purposeful efficiency of people who had things to do and had assessed the visitor as not immediately my problem. The rest continued toward what Ethan could tell from the layout was the direction of Xavier's office — the spatial logic of the building suggested it, confirmed by the x-ray vision which he was using at very low engagement because using it at full engagement in this building felt like reading someone's mail.
Jean Grey was behind him and slightly to the left, which he was aware of in the specific way you were aware of someone who was paying close attention to you.
Logan was beside him, which he was aware of in a completely different specific way you were aware of someone who could produce foot-long indestructible blades from their hands and was deciding, on an ongoing basis, whether to do so.
Hank McCoy was on his other side, and Hank McCoy was currently presenting as a large, broad-shouldered man with the bearing of someone whose academic credentials and physical presence coexisted in an unusual configuration. But there was something else in the picture — a slight inconsistency in the way the light moved across his features, a periodic calibration that happened at the edges of his outline when he shifted position.
Ethan thought about it for two steps and identified it.
A holographic system. Some kind of emitter, probably worn, projecting a modified version of McCoy's actual appearance — the technology of it impressive, the execution nearly perfect. Nearly. At Ethan's visual acuity, the refresh cycle was just barely perceptible, a fraction-of-a-second lag when significant movement required the projection to update, like a high-quality video running at a frame rate that was excellent for human eyes and slightly insufficient for whatever his eyes currently were.
He filed it, decided it was relevant to mention, and waited for the right moment.
---
Xavier's office was exactly the office it should have been.
Books organized with the logic of a mind that filed by association rather than category, the system opaque to outsiders and presumably perfect for the person who'd built it. A desk with the surface area of someone who works on multiple things simultaneously. Two chairs facing it, a third against the wall. A chess set on a side table — two games in progress simultaneously, which was either hospitality for frequent opponents or something about how Xavier's mind worked. Probably both.
Xavier positioned himself behind the desk without the desk being a barrier, the same trick Ethan had noticed in other people who were good at conversation. Mystique took the chair against the wall with the self-contained ease of someone who had survived in rooms with powerful people for a long time and had developed strong opinions about sightlines. Logan stood near the window. Jean Grey sat in one of the facing chairs.
Ethan took the other.
He looked at Hank McCoy, who had remained standing near the door with the slightly uncertain posture of someone who'd come in mostly out of curiosity and hadn't committed to staying.
"Dr. McCoy," Ethan said, keeping his voice conversational, "you can disengage the holographic system if you want. It's well made, but my vision catches the refresh cycle."
The room produced a specific quality of silence.
McCoy looked at him. The expression was the one scientists made when something had interrupted the experiment they thought they were running, and they replaced it with a different and more interesting experiment entirely. "You could see the refresh cycle," he said. It was not quite a question.
"The frame rate is nearly perfect," Ethan said. "And I mean that. For any normal human visual system, it would be completely invisible. I have a — I'll call it an extraordinary visual range." He paused. "I'm not saying this to make you self-conscious about it. I genuinely think the tech is impressive. I'm mentioning it because—"
"Because if you can see the flaw, you can describe it," McCoy said, with the rapid uptake of someone whose scientific mind had already run ahead of the conversation. He was smiling now, or nearly — the expression of a person who had just found something worth examining. The holographic projection flickered off, and Hank McCoy stood in his actual configuration: blue-furred, large in the specific way of someone who was genuinely physically substantial rather than a visual trick, his features carrying the particular dignity of someone who had made peace with being remarkable.
He looked, Ethan thought, considerably better than himself.
"Tell me exactly what you saw," McCoy said, pulling the third chair around and sitting down with the focused energy of a man redirecting entirely. "The specific nature of the visual artifact."
Ethan described it — the movement lag, the frame-edge inconsistency, the way the recalibration was triggered by rapid position change rather than slow movement. McCoy listened with the complete attention of someone taking notes in his head, his expression moving through several phases of yes, I know that problem, and I hadn't considered that specific manifestation of it.
"The obvious fix would be increasing the refresh rate," Ethan said, "but I'd guess there are power consumption constraints that make that difficult. Alternatively, a predictive model — if the emitter could anticipate the direction of movement rather than responding to it—"
"The latency is on the processing side," McCoy said, half to himself. "If the motion prediction could be integrated at the hardware level rather than the software—"
"Hank," Xavier said, with the gentle precision of someone who had experience redirecting McCoy's scientific enthusiasm back toward the present. "Perhaps we could continue this afterward."
McCoy looked up with the slightly apologetic expression of someone who had been caught being himself. "Of course. Yes. Apologies." He did not look particularly apologetic. He looked like someone putting an interesting problem in a pocket for later.
Xavier turned to Ethan with the full, patient attention that was apparently just how he looked at people. "You came to visit us," he said. "I'm curious about what brought you here specifically."
Ethan thought about the question — not the answer, which was ready, but the question itself. Xavier was a telepath who couldn't read his mind, which meant he was working from what was observable and what was offered, the same limited information anyone else had. He was asking genuinely.
"I had suspicions that mutants were real," Ethan said. "I'd seen some things since I arrived in the area — nothing definitive, but enough to make the hypothesis compelling. And I found out about this place — not through any complicated research, just library records and some basic geographic cross-referencing." He paused. "Once I knew it was here, I couldn't really justify not coming. I wanted to meet people with genuine mutations. See it firsthand, not as a theory."
"And has the visit met your expectations?"
"Exceeded them," Ethan said, and kept his expression neutral over the extent that his interior wanted to append to that.
Logan made a sound that might have been a quiet grunt/laugh.
Xavier looked at him with the expression of someone filing an observation. "You don't seem alarmed by any of this," he said. "Most people encountering this particular assembly for the first time have a more—" a slight pause searching for fair phrasing "—varied response."
"I'm not most people," Ethan said. Which was true in every available sense.
Scott and Bobby had already excused themselves — he'd heard the quiet conversation in the hallway before they'd moved off, the tone of nothing immediately threatening, back to regular schedule. The room was now Xavier, Jean, Logan, Mystique, and McCoy, the latter still visibly thinking about holographic refresh rates.
He looked at Mystique.
She had been watching him from the chair against the wall with the steady, evaluative quality that he'd been aware of since the driveway — a professional watchfulness, the kind developed over long experience with dangerous situations and the kind of people who caused them. She had the slightly uncanny quality of someone who was very good at wearing a face that wasn't theirs.
"This might be a rude question," Ethan said, directing it at her with the genuine, uncombative tone of someone who was asking rather than demanding, "but are you more comfortable in this form, or your natural one?"
The room shifted.
Mystique's expression didn't change — she was far too experienced for that — but something in the quality of her stillness changed, a subtle tightening that he read as someone deciding how to respond to being correctly identified.
"What do you mean by that?" The voice was even, calm, the careful neutrality of someone buying time to assess.
"I just had a feeling," Ethan said. "Don't worry about it. I just wanted to mention it — if you're more comfortable another way, don't feel like you need to maintain anything on my account."
Mystique looked at him. He looked back without the pointed directness of someone making a challenge and without the evasiveness of someone pretending not to have said what he'd said. Just open, genuinely meaning it.
She didn't shift. She held the blonde form with the same ease as before, which was itself a kind of decision. But something in her expression had changed slightly — the wariness recalibrated toward something that wasn't exactly trust but was a neighbor of it.
Xavier, Jean, and McCoy were all looking at Ethan with the collective expression of people encountering a pattern they needed to explain.
"You knew Hank had a concealed mutation," Xavier said, carefully. "And you seem to be aware that our guest is not presenting in her natural form."
"Your visual acuity accounts for the first," McCoy said. "But Raven's transformation—"
"Just a feeling," Ethan said again, honestly. "I've been finding I pick up on things."
Xavier looked at him with the expression of someone deciding to address the more important question. "May I ask about your powers directly?"
"Yes," Ethan said. "But first—" he looked at Xavier directly, "—you can't read my mind, can you?"
A beat. "No," Xavier said. "I can't."
Ethan nodded. He looked at Jean. "Neither can you."
Jean's expression moved through something quickly. "No," she said. "I can't."
"I felt two separate attempts," Ethan said. "When I was standing at the gate. Very gentle — I barely noticed. It felt like someone brushing a hand across a window." He paused. "I'm not bothered by it. I understand why you'd want to know what you were dealing with. I'm just establishing where we are." He looked at both of them. "You're both telepaths."
Xavier's expression had moved into something that was deeply interested and carefully controlled. "How did you know that?"
"Because those were the only two sensations that felt like that," Ethan said. "Everyone else in the room registers differently to me. You and Jean Grey register as something that reaches."
Logan, at the window, made another small sound. This one was more definitely a laugh grunt.
"My powers," Ethan said, returning to Xavier's question. "Are growing. Continuously, as far as I can tell. I've had them for about five weeks. I'm stronger than I was when I got them, faster, more durable. I fly." He paused. "I don't know the ceiling yet. I'm not sure there is one, exactly." Another pause. "I don't know how I got them. That's true — I have theories, but not certainty." The second part was almost entirely true. He knew the fact of it, mostly. The how was genuinely unclear.
"You don't seem like a mutant," Xavier said. He said it with the careful accuracy of someone who understood the distinction mattered.
"I don't think I am," Ethan said. "The origin doesn't fit." He looked at Xavier. "Does that change anything about how you see this conversation?"
"No," Xavier said. "What changes things is what someone does, not what category they fit into." He said it simply, without performance, the statement of a principle so settled it didn't need emphasis.
Ethan felt something that he chose not to examine too closely because he was trying to maintain a functional exterior.
He looked at Jean Grey.
She'd been watching him since they sat down with the focused expression he'd noticed on the driveway — the one he'd initially read as a professional assessment and was now reading as something more specific. She was studying him. Not warily, not analytically in the way McCoy was analytical. More like someone who had encountered something they'd never encountered before and were trying to understand what it meant.
"Why are you looking at me like that?" he asked. Genuinely curious rather than challenging.
Jean blinked, as if being caught in the act of something she'd thought was private. "I'm sorry," she said. "I'm just—" She paused, and the pause had honesty in it. "I've never met someone I couldn't read. Not without a physical barrier involved." She glanced at Logan briefly. "I can always get something, even when I'm not trying to. Surface emotion is the only thing I can get from you, intention, the basic texture of someone's mind I can't." She looked back at Ethan. "You're completely opaque. I know you're there. I can read your physiology in a general sense. But your mind is—" She gestured slightly, the gesture of someone searching for a word.
"There and not accessible?" Ethan offered.
"Exactly that." A pause. "It's disorienting. In an interesting way."
Ethan looked at Logan. Logan was watching the whole thing with the expression of someone who had been in enough rooms with enough remarkable people that his baseline for remarkable had adjusted several times upward, and was currently doing it again.
"I have a question for you," Ethan said.
Logan's eyebrow moved approximately two millimeters, which was apparently his version of go ahead.
"Do you want to spar?"
The two-millimeter eyebrow became a slightly different shape. Logan looked at Ethan with the assessing quality of someone running a calculation, and then the corner of his mouth moved into the expression that was as close to a grin as the configuration of his face typically managed.
"Sure, bub," he said.
Xavier cleared his throat. "It was a genuine pleasure to meet you," he said, which had the quality of both an ending and something more deliberate — the tone of a man who had decided that keeping this particular individual on good terms was a policy worth maintaining. "You're welcome here whenever you'd like to visit."
"Thank you," Ethan said, and meant it more comprehensively than he could explain.
---
The grounds behind the mansion had the quality of space that had been designed for various purposes and had settled into a comfortable multi-use arrangement — the formal garden areas dormant and skeletal in November, the wider lawn providing the kind of open space that a school with unusual students occasionally needed. Jean, McCoy, and Mystique had come out to watch, which Ethan had anticipated, and Logan had apparently anticipated, and neither of them commented on.
Logan rolled his shoulders once and then stopped pretending to warm up, because Logan did not warm up.
The claws came out.
Ethan had known they were coming and still found the sound — the specific metallic snkt of adamantium moving through living tissue and into open air — more arresting in person than any version of it he'd encountered before. Three blades per hand, each one catching the November light with the flat, absolute brightness of metal that took an edge as a fundamental property rather than a technique.
He looked at them.
His x-ray vision had engaged automatically when the claws extended, the kind of reflexive information-gathering that his enhanced senses had developed into a default mode. He got the picture of the adamantium skeleton immediately — and immediately noted that the X-ray stopped at the metal. Didn't penetrate it. The bones beyond the adamantium coating were visible, but the metal itself was opaque to the vision.
Interesting, he thought. Completely useless information for the foreseeable future, but interesting.
He also registered, with the part of his attention that was cataloguing rather than responding, that those edges were extraordinary. Not sharp in the way of a well-made knife, which was sharp relative to other knives. Sharp in the way of something that had been engineered to cut anything and had delivered on the specification.
Logan moved.
He was fast. Genuinely, impressively fast — not Ethan-fast, not the soft-focus slow-motion quality that Ethan's perception applied to normal human movement, but fast in a way that acknowledged the gap was smaller than it might have been. The first combination came with the efficiency of someone who had had these claws for a very long time and had learned to use them the way other people learned to use their hands — naturally, without thinking about the mechanics.
Ethan moved inside the first swing. Outside the second. Under the third.
He wasn't touching Logan. He'd decided from the start that the sparring's informative purpose was served by evasion rather than exchange, at least until he had a better sense of what he was working with. Logan read this within about thirty seconds and adjusted — the attacks becoming less about hitting and more about driving, testing the response, probing for the pattern.
There wasn't one, which Logan registered with the slight change in his approach that meant he'd moved from pattern recognition to something else. The claws came closer. Still not connecting. Ethan was moving in the margins of the attacks with the precise economy of someone whose reaction time made the margins wider than they looked from outside.
He was also watching the claws carefully, specifically, studying the way the adamantium caught and scattered light and thinking about those edges and whether they would do anything meaningful against his skin. He still didn't have confirmed data on what very sharp things moving very fast did to his durability. The knife test had covered blunt force and moderate blade pressure. This was a different category.
He decided not to find out today.
Logan feinted left and drove right with the specific misdirection of someone who had used this combination enough times to know what it looked like to people whose attention could be directed. Ethan moved with the feint and then read the real attack and was already going the other way when the blades passed through where he'd been.
Logan straightened and looked at him with the expression that had replaced the combat focus — the one that was doing a genuine assessment rather than a tactical one.
"You going to hit back at some point?" he said.
"I was getting there," Ethan said.
"Uh huh."
Ethan looked at him. "Quick question first. You have a healing factor, right?"
Logan's expression moved through the specific configuration of someone being asked a question whose relevance they're working out. "Yeah," he said.
"Significant one?"
"Pretty significant."
"Good." Ethan paused. "No hard feelings?"
A beat. "Sure," Logan said, in the tone of someone who was now more curious than cautious.
Ethan hit him.
He'd been building toward the calibration since the fight started — watching Logan move, reading the physical confidence of someone who had taken serious hits and healed from them, establishing a sense of what appropriate looked like in this specific context. He'd been running the number in the background the whole time: what fraction of his genuine capacity was fair and interesting rather than negligent.
He decided on something in the range of half, maybe slightly above.
He threw a straight right hand with that fraction behind it and aimed it at the center of mass.
Logan's instincts were extraordinary. That was the thing that struck him first — before the impact, before everything else, the way Logan's entire body registered what was coming a fraction of a second before it arrived. His hair stood on end. His weight shifted backward. Something in his eyes said that is a different category of thing than what I was expecting, and his body was already trying to implement a response.
Ethan felt the decision happen, somewhere between throwing and connecting, and reduced the output further. Not to nothing — a blow with nothing behind it wasn't honest, and Logan wouldn't respect it. But he took another twenty or thirty percent off the top in the last available moment.
The punch connected.
Logan left the ground.
Not dramatically, not with a theatrical arc — but clearly, unambiguously, his feet departing the frozen November grass with the simple physics of something that had received more force than its weight could anchor it against. He traveled backward through the air, through the first tree at the lawn's edge, through the second, through the third and fourth, and several more, the sound of it carrying back across the grounds in a sequence of impacts that had the almost rhythmic quality of something moving through things that couldn't stop it.
Then silence.
The three spectators were very still.
Jean Grey was looking at where Logan had disappeared into the treeline with an expression that contained several things simultaneously and was taking a moment to sort them.
McCoy had his arms folded and was looking at Ethan with the scientific expression rerouted entirely, the holographic problem completely forgotten in favor of the considerably larger physics question that had just presented itself.
Mystique was very still in the specific way of someone who had just recalibrated something fundamental.
Ethan stood on the lawn and looked at his hand.
Half power. Approximately. Maybe a bit less, at the end there.
He walked toward the treeline.
He'd made it about halfway when he heard it — the sounds of movement through undergrowth, unhurried, getting closer. Logan emerged from between two trees that had not had a Logan-shaped gap in them before today, walking with the slightly deliberate quality of someone whose healing factor was earning its keep and preferred not to have that fact examined too closely. Some debris in his hair. His jacket had opinions about what had just happened to it.
He walked up to Ethan and stopped.
Ethan looked at him carefully. "You all right?"
Logan's expression went through something. He looked at Ethan with the eyes of someone who had been alive for a very long time and had learned to accurately assess the thing standing in front of them, and for a long moment, he was just doing that — assessing, categorizing, arriving somewhere.
"Fine," he said. His voice was in its usual quality. "Ribs are already sorted." A pause. "Glad you're not an enemy, bub."
Ethan felt something loosen in his chest that he hadn't realized was tight. "Me too," he said, and meant it completely.
Logan looked at him for another moment. Then he looked back at the gap in the treeline with the expression of someone doing a professional estimate of the damage. "That wasn't full power," he said.
"No."
"How close?"
Ethan considered being diplomatic and decided Logan would prefer accuracy. "About half. Less, at the end."
A long pause. Logan nodded once, the nod of a man filing important information in the correct location. Then he said, "I'm going to go look at my motorcycle," which was apparently how Logan signaled that he needed to think and wasn't going to discuss it further.
Ethan watched him go.
"I'll come back tomorrow, if that's okay?" he called toward Xavier, who had come to the edge of the grounds' formal area and was watching with the expression of a man who had seen remarkable things in his life and was adding this one to the list.
"Of course," Xavier said. "We'll be here."
---
He flew back to Manhattan in the November dusk, the city assembling itself on the horizon ahead of him, and thought about the afternoon.
He thought about Jean's face when Logan had gone through the trees. He thought about McCoy already mentally redesigning the holographic emitter on the walk back inside. He thought about Mystique, still in her borrowed blonde form, watching him leave with the expression of someone who had a question they hadn't asked yet.
He thought about Xavier at the gate, the voice through the intercom, and the office with the chess games in progress.
He let himself feel it properly, in the private space of three hundred feet of altitude and the wind and the setting sun doing something extraordinary over New Jersey.
He'd just spent an afternoon with the X-Men.
He'd punched Wolverine through eight trees.
He'd been told by Charles Xavier that he was welcome back whenever he wanted.
He let himself be eighteen years old about it for about thirty seconds, which was the amount of time it took to cross into Manhattan airspace, and then he descended toward the city and the hotel and the rest of the list that still needed doing.
---
Back at the mansion, the debrief was not a formal meeting. It was the kind of conversation that happened in the kitchen while people were doing other things, which was how the most honest conversations in the mansion usually happened.
Logan had come back from the garage and was drinking coffee with the expression of a man who had decided something and was going to share it on his own schedule.
Jean was heating something on the stove and was clearly still processing.
McCoy had a notebook out on the table and was writing in it in the dense shorthand he used when ideas were arriving faster than full sentences could contain them.
Mystique was at the table with a cup of tea, in the same borrowed form, looking at the window.
"He held back," Logan said. It wasn't a question.
"We know," Jean said.
"Not just a bit. I mean—" Logan paused, which was unusual enough that everyone looked at him. "Right before it connected. I felt it change. He'd decided on something, and then he changed it at the last second." He looked at his coffee. "Whatever he decided on first would've been worse."
"How much worse?" McCoy asked, pen still.
"The thing I felt was..." Logan considered the right word with the care of someone who had learned that precision mattered in these assessments. "Significant. What actually hit me was—" He stopped.
"We all saw what hit you," Jean said, with the careful tone of someone being accurate rather than unkind.
A silence.
"Right," Logan said. "So."
Bobby Drake, who had come in for the last thirty seconds of this conversation, looked between the people at the table. "So... could we actually beat him? If we had to?"
Jean was quiet for a moment. "I couldn't read his mind. If I can't reach the mind, my powers are less effective — I'd be working against a physical system I don't fully understand."
"I could try to freeze him," Bobby said.
Several people looked at him with the careful expressions of people deciding how to respond to something.
"You could try," Jean said.
"Straight up fight?" Logan said, answering Bobby's original question. "No." He said it without drama, the flat accuracy of a practical assessment. "Not straight up."
McCoy was writing again. Mystique was still looking at the window.
"He knew," she said quietly.
Everyone looked at her.
"He knew it wasn't my natural form," she said. "Not from the holographic thing — that was Hank. He knew about me specifically. And he told me it was fine." She paused. "He wasn't performing tolerance. He meant it."
A silence that had a different texture from the previous ones.
"Charles," Logan said, "good thing the kids were on a field trip today."
From across the room, in the direction of the study, Xavier's voice carried with the mild precision of someone who had been listening: "Yes," he said. "I thought so too."
