The purification treatments were an accident.
Not carelessness — thoroughness. The kind of accident that happened when you were paying close enough attention to notice something you hadn't expected to find.
He had been maintaining Lyra's monthly treatments for almost a year. They had become routine in the way repetitive skilled work became routine — not thoughtless, never thoughtless when the work was on his sister's lungs, but flowing. Efficient. The focused attention settling into the task without the labored concentration of the early months.
During a session in his fourth year, Lyra asleep and Shadow under the bed, he became aware of something he had not previously noticed. Not in her lungs. In the surrounding tissue. In the water content of the body itself and the specific mineral profile of that water.
The diagnostic sense had been expanding alongside the healing sense, developing in resolution the same way the healing sense had. And what it was now showing him — in detail it hadn't previously reached — was the chemical profile of tissue that had been living for years in a body drinking imperfectly clean water, eating food that was adequate but not optimal, working in conditions that produced low-level inflammatory residue that the body could manage but never fully clear.
He had known abstractly that the body accumulated impurities. He had read it in his previous life in the form of nutrition studies and environmental health research. He had known it as information.
He had not seen it until now.
He held what the diagnostic sense was showing him and thought: she is healthier than she was. She is not as healthy as she could be.
He thought: is the same true of everyone else?
He ran the scan across the household over the following nights, each family member in turn while they slept. The answer was yes. His mother had the profile of someone who had been dealing with hard water her entire adult life. His father had the profile of someone whose joints had been working past their ideal threshold for fifteen years. Thomas had the profile of a growing teenager whose body was managing nutritional demands with what was available, which was not always enough.
He ran the diagnostic sense on himself and found what he expected — and then found something that surprised him. His own healing sense, running background maintenance on his body continuously since before he had consciously directed it, had already been addressing most of what he was now seeing in the others. He had been purifying himself without knowing it. His cells were cleaner than anyone else in the household by a significant margin.
He filed this under: things that explain things. Then he went back to considering what to do about the rest.

He began with his father.
Edric's need was the most urgent by the measure of long-term structural damage — the joints, the circulation, the early accumulation of wear that in his previous life's medical framework would have been the foundation of the chronic conditions that made old age harder than it needed to be.
He also began with his father because his father's improvement would be most easily attributed to ordinary causes. A farmer whose physical condition improved slightly in winter was a farmer doing well. No one would ask pointed questions about a farmer doing well.
The sessions with Edric were different from the sessions with Lyra. Lyra's work had been surgical — targeted, precise, addressed to a specific condition. This was environmental remediation. The diagnostic sense found the accumulations, the healing sense cleared them: mineral deposits drawn out through the tissue and processed by the body's own elimination over the following days, inflammatory residue cleared from the joint capsules where it had been building for years, cellular hydration corrected toward what it should be.
He worked slowly. Three sessions a week, alternating areas, never taking more in a single night than the body could comfortably process. He had learned from the work on Lyra that the body needed to participate in its own improvement — needed room to do its part rather than being overwhelmed by an intervention that outpaced its capacity to adapt.
The changes became visible in six weeks.
Edric straightened. Not dramatically — not the sudden posture of a man who has had something corrected, but the gradual ease of someone from whom a constant low-level discomfort has been removed, who is no longer arranging himself around it without knowing he's doing it. He stopped leading with his shoulders. His stride lengthened slightly. He came to dinner one evening and sat down without the small intake of breath that had, Arthur now realized, been so consistent a part of his father's movements that it had become invisible.
His complexion changed. The weathered texture of someone who had been working outdoors for decades began to ease. Not reverse dramatically — not the sudden youth that would have required explanation — but soften. The chronic low-level inflammation that had been Edric Voss's baseline for years reduced, and what was underneath it was simply healthier. More itself.
His hair, rough and dry with the texture of someone whose body had been redirecting hydration toward higher-priority systems, began to settle.
Arthur watched all of this with the satisfaction of applied work going correctly.

Mira noticed in the seventh week.
He had been watching for it. Mira Voss missed very little, and the question was not whether she would notice the changes in her husband but when — and whether the when would be before or after the changes had progressed far enough to need either a convincing natural explanation or the truth.
She noticed on a Sunday morning in good winter light — the low-angle kind that came through the kitchen window and illuminated the table honestly. Edric was eating breakfast. Mira set a bowl in front of him and then didn't move. She stood there and looked at him with the focused attention of someone who had just seen something unexpected and was deciding how seriously to take it.
Edric looked up. 'What?'
'You look different,' she said.
'I've looked the same for thirty years.'
'That,' she said, 'is not true anymore.'
Edric touched his face with one large hand, the way men did who were not in the habit of examining their own appearance and found the suggestion startling. He said he had been sleeping better. Which was true — the reduction in joint inflammation had genuinely improved his sleep and he could report it with full sincerity, because he had noticed it himself even without knowing the cause.
Mira looked at him for another moment.
Then she looked across the kitchen at Arthur.
Arthur was eating his porridge with the focused attention appropriate to a child engaged with porridge. He was also completely aware of the look, and what it meant.
She knew.
She didn't say anything that morning. She was methodical — she had seen something, formed a hypothesis, and was going to confirm it before acting on it. He watched her confirming it over the next four days. Tracking the changes in her husband. Looking at Arthur at intervals with a gaze that was not quite accusatory and not quite questioning but was something that combined both without being either.
On the fifth day she came to find him in the yard.
