The debate had continued again since before, with neither participant finding a satisfactory conclusion.
"The dimensional routing is irrelevant," Kurt declared, from his position at the kitchen table where he had established himself with coffee and the moral certainty of someone who had prepared for this argument. "What matters is the experience of arrival. When I teleport, an event occurs. A presence. People know something has occurred."
Ilyana sat across from him, hands flat on the table, her patience clearly intentional. "When you teleport," she said, "there is a sound, a smell, and a flash of light. Each is a liability if the arrival should be undetected."
"Not every arrival is supposed to be undetected," Kurt said. "Some arrivals benefit from announcement."
"A tactical mobility tool that announces itself is less effective," she said. "This isn't complicated."
"You are evaluating a symphony by whether it could serve as a library," he replied. "The criteria are incorrect."
Ilyana regarded him. "You're comparing your teleportation to a symphony."
"I am using a metaphor," he said, maintaining his composure.
"The metaphor is wrong, too."
Bobby Drake passed the kitchen doorway, recognized the conversation, and continued on.
Rogue appeared in the doorway, glanced at them, and continued walking. She paused briefly to say, "Neither of you will convince the other, and you've both been at this for two hours. Consider what that means."
"It means the matter is complex," Kurt said.
"It means you both enjoy arguing," Rogue said and left.
Kurt looked at Ilyana. "She's correct," he admitted.
Ilyana met his gaze. "I know." She paused. "Your teleportation is useful."
Kurt sat up straighter.
"In specific contexts," she added.
He hesitated, then accepted this as a concession. "Your stepping discs are also useful," he replied. "In specific contexts." He tilted his head. "Different ones."
Ilyana looked at the window. "Sure," she agreed.
The debate was tabled, meaning it would resume at breakfast tomorrow with the same energy and without any recollection of the previous resolution.

Ethan found Raven, Rogue, and Jean in the sitting room mid-morning, with Ilyana seated by the door as she had been since yesterday.
Raven wore the sling ring, practicing its rotation with focused attention. Jean read a book on the history of psychic research from Xavier's library, occasionally making notes in the margin. Rogue played her guitar, moving through a slow, exploratory piece without gloves.
He stood in the doorway, observing all three and reflecting on how improbable this arrangement once seemed and how accustomed he had become to it.
"I need to go into the city," he said. "Probably most of the day. I have something I need to look into."
Jean looked up from her book. "Something dangerous?"
"Something potentially very useful," he said. "Not dangerous. I'll explain properly when it's more than a plan."
Rogue's hand stilled on the guitar strings. "How interesting is it going to be?"
"It might become very interesting," he said. "That's the part I'm trying to work out today."
Raven looked at him with the measured attention she brought to things she was deciding whether to ask more about. She decided not to. "Come back before dinner," she said.
"Planning to," he said.
Ilyana watched him leave with a thoughtful expression. She did not ask where he was going, whether out of discretion or recognition that it was not her place to ask.

Ethan sent a text to Coulson from the subway platform while waiting for a train he did not need, choosing it for the sense of normalcy.
Looking for background on a scientist. Name: Otto Octavius. Physicist, approximately 35. Applied energy research. Let me know if SHIELD has anything on file.
The response arrived in eleven minutes, faster than Ethan expected. This suggested either that the name was already in a database or that Coulson's research instincts had improved through recent experience.
Otto Octavius. 35. PhD in applied physics, Columbia. Currently, an adjunct research position at NYU while running a small private lab in Lower Manhattan. Published work in theoretical energy containment — some interesting papers, not widely cited yet. No SHIELD flag — not dangerous, not connected to anything we're tracking. Just a scientist without enough funding for his ambitions. Why?
Ethan typed back: Potential collaboration. Energy project. Nothing you need to flag.
A pause. Then: Want me to run anything deeper?
The lab address would help.
The address arrived thirty seconds later. Coulson's efficiency had increased alongside his growing confidence in the arrangement.
Ethan pocketed the phone and took the next train south.

The lab occupied the third floor of a subdivided building in Lower Manhattan. The ground floor housed a dry cleaner, the second floor two accountants and a small law practice, and the third floor was Otto Octavius's applied physics lab, filled with a significant amount of custom equipment.
The door was open.
Ethan knocked on the frame anyway.
The man at the central workbench looked up, clearly interrupted, and considered how to respond.
Otto Octavius was compact and precise in appearance: dark hair, thick-framed glasses, and the build of someone who worked at a bench. He regarded Ethan with the direct assessment of someone used to evaluating problems efficiently.
"I didn't schedule any meetings today," he said.
"I didn't ask to be scheduled," Ethan replied. This response would either end the conversation or allow it to continue, depending on Octavius.
Octavius took off his glasses, cleaned them on his coat, and put them back on. "You're eighteen years old," he said.
"I think so," Ethan said.
"You're also standing in my lab, which means you came here specifically, which means you know what I do." He set down the instrument he'd been holding. "What do you want?"
Ethan looked at the bench — the equipment, its configuration, the specific project that was partially assembled and recognizable if you knew what to look for. "You're working on a contained high-energy plasma configuration," he said. "The magnetic containment ratios are interesting. You've modified the field geometry in a way I haven't seen published."
Octavius regarded him differently, recalibrating after expecting a sales pitch and receiving something else.
"Who are you?" he asked.
"Someone who has been thinking about miniaturized solar energy containment for a while," Ethan said. "And who came across your work on theoretical plasma confinement and thought the two problems might be related in useful ways."
Octavius pulled out a chair, sat, folded his hands, and gave Ethan his full attention, having decided the conversation was worthwhile.
"Miniaturized solar containment," he said. "You mean actual solar spectrum replication. Not just a plasma approximation."
"Full-spectrum solar output in a contained form," Ethan said. "Small enough to be portable. High enough output to be genuinely useful at scale."
"That's a twenty-year project with current technology," Octavius said. "Maybe longer."
"Current publicly available technology," Ethan said. "There's more available than the published literature suggests."
Octavius's eyes narrowed, not in suspicion, but as someone weighing the credibility of an unexpected claim.
"What kind of resources are you claiming access to?" he asked.
"A research facility with capabilities beyond what you have here," Ethan said. "A physicist on staff who will understand what you're working on and who I expect will want to improve it within the first twenty minutes of your conversation." He paused. "And funding, if the project goes somewhere real."
"What's the end goal?" Octavius asked. "Not the technical goal — the purpose. What does someone want a miniature sun for?"
"A personal project of mine," Ethan said. "Nothing harmful. I won't be more specific than that."
Octavius studied him for a long moment, evaluating the claim with the thoroughness of a scientist reviewing evidence and logic.
"You're eighteen years old," he repeated, this time noting it as an anomaly rather than dismissing it.
"Yes," Ethan said.
"And you have access to a research facility."
"Yes."
"And a physicist."
"Hank McCoy," Ethan said. "Look him up if you want a sense of who you'd be working with."
Octavius's expression shifted slightly; the name was familiar to him.
"Henry McCoy," he said. "The papers on mutation-adjacent biochemistry from the last few years."
"The same," Ethan said. "Applied physics is not his primary field, but I would not describe it as outside his range."
Octavius was silent for a moment, genuinely considering the proposal. He glanced at the equipment, then at Ethan, then out the window, and back again.
"I'll come see the facility," he said. "Tomorrow. If your description is accurate, we have something to discuss. If not, I have only lost a morning." He paused. "I have lost mornings for less."
Ethan gave him the address.

Xavier's study had the atmosphere of a room accustomed to significant conversations and ready for another.
Xavier set down his pen as Ethan entered and gave him his full attention, a genuine strength of his.
Ethan explained the Octavius situation directly: the scientist, the project, the upcoming visit, his personal motivation for a miniaturized solar source, and the broader potential benefits. He presented both reasons equally.
Xavier listened without interrupting.
"The energy implications alone would justify the research," Xavier said, when Ethan finished. "If Octavius is as capable as you're suggesting, and if the project produces what you're hoping for, the applications extend well beyond your personal use."
"That's the honest case for doing it here," Ethan said. "The less altruistic case is that I want the absorption gains faster."
Xavier regarded him, clearly satisfied with both reasons and not concerned with their order. "You've been transparent about your development as a resource rather than a threat from the beginning," he said. "I have no objection to facilitating it." He pressed his fingers together briefly. "What does Octavius know about this facility?"
"That it has capabilities beyond his current lab and there is a physicist worth talking to," Ethan said. "Nothing about the school or the students."
"Then we'll receive him professionally and let the work speak for itself." Xavier reached for his pen. "Use the east annex lab — Hank will know which one. It's the best-equipped space for this kind of project."
"Thank you," Ethan replied.
He was at the door when Xavier spoke again. "Ethan." There was an added weight to his tone. "As you grow stronger, I trust your judgment in how you use that strength. I want you to know that."
Ethan turned back and looked at him.
"I know," he replied. "Thank you for saying so."

Hank McCoy listened to the pitch for about sixty seconds before he began asking questions.
"Full-spectrum solar output in a miniaturized containment field," he repeated from his position at his lab bench. "The plasma temperature required would need—" he was already moving to a whiteboard, "—the magnetic confinement approach is interesting, but the heat exchange problem is substantial. What's the containment geometry he's been working with?"
"I don't know the specifics," Ethan said. "That's what tomorrow's conversation is for."
"Yes, of course, the conversation." Hank turned from the whiteboard and looked at Ethan with the expression of someone who had been given a problem and was already several steps into it. "What's the output target? In terms of spectral replication — are we looking at approximation or true full-spectrum?"
"Full spectrum," Ethan said. "Whatever's closest to unfiltered solar output."
Hank made a sound of scientific enthusiasm. "That's a much more difficult problem than approximation. The UV component alone—" he began writing "—but if Octavius has modified plasma confinement geometry, there may be an approach through field shaping rather than direct output regulation that could bypass some of the—" He stopped and looked at Ethan. "You said tomorrow."
"Tomorrow," Ethan confirmed.
"I'll prepare some questions," Hank said.
"I expected as much," Ethan said.
"They might go over your head," Hank said, with the honesty of someone who was not trying to be condescending and was simply reporting what he anticipated.
"I told Octavius the same thing," Ethan said. "I'll be there for the introduction and the coffee."
Hank appeared to consider this a reasonable division of labor.

When Ethan returned, the sitting room reflected its late-afternoon routine: Raven with her notes, Rogue exploring the guitar, and Jean looking up from her book, half-engaged and half-aware of the time.
Ilyana was in her chair by the door.
He sat down and summarized the day's events directly: Octavius, the upcoming visit, Hank's enthusiasm, and Xavier's approval. He omitted Coulson's involvement because operational habits persisted, and his role was not for general knowledge.
Jean set her book down. "A miniature sun," she said.
"The theoretical version," Ethan said. "Octavius has approached the plasma containment problem differently than published research indicates. If he and Hank can collaborate effectively, the project will become viable."
Raven looked up from her notes. "And if they can build it."
"Then the absorption gains will accelerate significantly," he said. "The space sessions are effective, and the compound effect is real. However, access to a contained solar source at close range without oxygen limitations changes the equation entirely."
Rogue's hand paused on the guitar strings. "How much stronger does that make you?"
"I don't know," he said honestly. "That's part of what I want to find out."
Ilyana watched him from her chair by the door, her expression patient and observant. She had not spoken since his arrival, which was typical for her, but her attention seemed different this evening.
He looked at her. "Your thoughts?"
She tilted her head slightly. "I'm trying to determine where the ceiling is," she said. "Each time I think I've found it, there is more beyond."
"There might not be a ceiling," he said.
She considered this for a moment. "That is either the most useful thing in the world," she said, "or the most dangerous."
"Usually both," Raven said from her chair, without looking up from her notes. "In roughly equal measure."
Ilyana turned to Raven, her expression shifting in recognition of someone whose quiet observations were worth noting.
She went back to watching Ethan. She didn't leave.

Later that night, with the room quiet and Raven and Rogue deeply asleep, and Jean's breathing steady down the corridor, Ethan lay in the dark, his thoughts turning east.
The Stark property.
Howard and Tony, working together on their basement project—their first true collaboration—focused on the laser, the particle beam, and Tony's developing theoretical framework. They were two of the most technically capable minds in the area, working on a problem closely related to tomorrow's discussion, though they did not yet realize it.
He could hear them if he focused: two heartbeats in the house next door—Howard's steady and slow, Tony's faster, reflecting a mind active even in sleep.
He thought they should know about Octavius and the upcoming project—not his personal motivation, but the project's scope and scientific potential. Tony would engage fully within minutes of understanding the objective.
The energy implications would interest Howard, while the engineering challenge would captivate Tony.
He decided that tomorrow's introduction should include a visit next door, anticipating a longer and more productive conversation than Octavius expected.
He closed his eyes.
The mansion was quiet at night, the Stark house next door peaceful, and somewhere in Lower Manhattan, Otto Octavius was likely still awake at his bench, working on a problem soon to be better resourced.
Ethan went to sleep.
