My Ultimate Sign-in System Made Me Invincible

Hearing what Diego said about the itching, the nurse picked up her glass tablet to look at the data the nanites were transmitting with their action and what she saw, shocked her.

The monitoring display had updated the moment the nanites activated.

She had expected data. She had been briefed on what the monitoring output would look like, with the clean columns of biological variables, the nanite activity indicators, the repair progress tracking she had spent two days learning to read during orientation.

What she had not been briefed on was the speed at which the nanite works.

The nanite activity column was not initializing. It was not running a startup sequence or establishing baseline readings before beginning work. It was already at full operational output, with every indicator live, the biological assessment complete and the repair prioritization already done.

She had depressed the injector thirty seconds ago.

She looked at the display and then at Diego and then at the display again.

The nanites had already mapped every biological variable in his body. The bilateral amputation sites. The phantom limb pain pathways. The nerve terminations at both residual limbs. The scarring. The malnutrition markers. The iron deficiency. The PTSD neurological signature. Every secondary condition listed in the intake scan had been assessed, prioritized, and assigned to an active repair queue. All in thirty seconds.

She looked at the nerve regeneration indicator for the left residual limb.

It was not at zero percent. It was already at two percent, and the number changed to three as she watched.

“Thomas,” she said, without looking away from the display.

Thomas was already moving. He crossed the room and looked at the display over her shoulder. He read it once, then read it again.

“Monitoring room?,” he said into his tablet. “You’re seeing this.”

The response from the monitoring room came back immediately. “Confirmed. We have full output. All indicators live. Nanite activity is — yes. We see it.”

There was a brief pause, as the people on the other end was taking in what they were seeing.

“All six volunteers are active,” the medical data analyst said. “All six displays are live. Deployment confirmed across the board.”

Thomas looked at Diego.

Diego was sitting very still, his hands resting on his thighs, his eyes open and fixed at a point slightly above the holographic monitoring display of his cot.

 His expression was concentrated. It wasn’t pained or frightened. Rather, it was filled with curiosity and intense focus on what he felt was going on in his body.

Marco was watching Diego’s face.

“Ask him,” Thomas said quietly.

Marco asked and Diego answered without looking away from the point he was focused on.

“He says the itching is in both legs,” Marco said. “Not just the left. Both. He says it’s deep. Not on the skin. It’s inside.”

Thomas looked at the display. The right residual limb nerve regeneration indicator had just crossed one percent.

“That’s the nanites,” Thomas said. “Tell him that’s the nanites working. Tell him that’s the correct feeling.”

Marco translated and Diego listened. Then something in his posture changed.

His mother had her hand over her mouth.

Thomas didn’t say anything. There was nothing to say that the display wasn’t already saying.

The nerve regeneration indicators for both limbs kept moving.

In Maya’s room, the sequence had been quieter.

Maya had watched the injector the way carefully and attentively. The nurse had positioned it at her shoulder she had looked away, not wanting to see that part.

She felt the entry point as a pressure and nothing more, and then it was done, and the nurse withdrew the injector and said it was finished.

Maya looked at her shoulder. Then at the nurse.

“That was it?” she said.

“That was it,” the nurse said.

Maya considered this.

“I thought it would be bigger,” she said.

The nurse smiled. “The nanites are very small.”

Maya accepted this, without saying anything else, as she lay back on the pillow.

Rosa was still holding her hand.

Thirty seconds after deployment, Maya’s expression changed.

“Mamá,” Maya said.

“I’m here.”

“Something is happening.”

Rosa’s hand tightened on Maya’s.

“I know,” Rosa said. “That’s supposed to happen. That’s what we came here for.”

Maya was quiet for a moment.

“It doesn’t hurt,” she said.

“Good,” Rosa said. Her voice was entirely steady. She was not going to cry in front of Maya. She had decided that before they left Guatemala City and she was going to hold that decision now.

Maya looked at the ceiling and kept her hand in her mother’s and let whatever was beginning, begin.

In Piotr’s room the nurse had administered the injection and stepped back and Piotr had sat with his hands in his lap and waited.

He was good at waiting. He had become very good at waiting.

The first thing he felt was warmth, beginning somewhere in his chest and moving outward from there, slow and steady. It was like the first effect of something taken for pain, except he hadn’t taken anything for pain in weeks because it had stopped working.

He looked at his hands.

His hands had been unreliable for months. The fatigue, the weight loss, and everything else. But his hands were in his lap and they were still and the warmth was moving through him and he was in a room on the moon and the window beside his bed looked through one-way glass into a corridor where observers from Poland were standing with their notebooks open and he thought, briefly, that it was strange to be witnessed by his own country.

He looked at the nurse.

“Something is happening,” he said, in Polish.

The nurse looked at the display and then at Piotr.

“Yes,” she said. “It is.”

Piotr nodded. He looked at his daughter, who was standing beside the bed with her hand on his shoulder.

He put his hand over hers.

He didn’t say anything. He didn’t need to.

He simply waited, the way he was good at waiting, and let the warmth continue.

The monitoring room at the base had all six volunteer displays live simultaneously.

The medical data analysts worked at their stations, eyes moving between displays, logging what the system flagged, pulling detail views on specific indicators when the numbers moved fast.

The general physician in the monitoring room stood in the center of the room and looked at the full grid, at the six green cells, all active, all transmitting, all showing nanite activity at operational output.

The nerve regeneration indicators were moving across four of the six displays. The malnutrition correction queue in Diego’s display was active alongside the nerve work, the nanites running parallel repair tracks without apparent conflict. The Parkinson’s neurological repair display, as Volunteer 42, was showing activity in regions she had not expected to move so quickly.

She pulled the detail view on Volunteer 42.

The nanite activity in the substantia nigra was already at seven percent and climbing. The dopamine pathway assessment had been completed. The repair prioritization had been set.

She stared at it.

In twenty-two years she had watched the medical literature on Parkinson’s treatment move in increments so small they required statistical analysis to detect. Progress measured in months of data across thousands of patients to establish a marginal effect.

The display in front of her was showing structural repair activity in the dopamine pathways of a single patient in real time, eleven minutes after deployment.

The display was showing record breaking numbers!

She stepped back from the display, picked up her tablet and began documenting and she wrote steadily, as the displays kept updating and the numbers kept moving.
