Kai woke up on the couch with his laptop still open on his chest. The screen had gone dark sometime during the night, but the room was lit by the early gray of morning. He sat up slowly and rubbed his face.

  Lian was already awake. She stood by the window, mug in hand, watching the street below.

  “You sleep at all,” he asked.

  “Enough,” she said. “You?”

  He shrugged. “In pieces.”

  She turned and handed him a mug. He took it without comment.

  “Anything new,” she asked.

  “Not much,” Kai said. “Hospital systems are tight. He is careful. Whatever he is doing is kept off the main network.”

  “That tracks,” Lian said. “He always liked clean lines.”

  Kai glanced at her. “You okay?”

  She took a sip. “I went in prepared to hate him. That part was easy. The rest was not.”

  Kai nodded. He did not push. He knew better.

  Later that day they moved again. Another short term apartment. Another set of cameras. Another routine that kept them from feeling too settled.

  By evening Kai had something.

  “I traced one of the equipment vendors from his lab,” he said, fingers moving fast. “Not medical supply. Private research distributor.”

  “Who do they usually sell to,” Lian asked.

  “Biotech startups. Military contractors. A few shell companies with no real footprint.”

  “And him,” she said.

  “And him,” Kai confirmed.

  Across the city the doctor sat in a windowless office far from the hospital. The walls were bare except for a single framed certificate he had never bothered to hang at work.

  The man across from him was polite. Middle aged. No accent he could place.

  “You have the data,” the man said.

  “Yes,” the doctor replied. “Preliminary results only.”

  “That is fine,” the man said. “We value speed.”

  If you discover this tale on Amazon, be aware that it has been unlawfully taken from Royal Road. Please report it.

  The doctor slid a tablet across the table. “This is not ready for exposure.”

  “We are not exposing it,” the man said calmly. “We are testing scalability.”

  The doctor frowned. “On what population.”

  The man smiled slightly. “Controlled environments.”

  The doctor looked down at his hands. “I need assurances.”

  “You have funding,” the man said. “You have autonomy. You have protection.”

  “I have conditions,” the doctor said.

  “Of course,” the man replied. “We respect ethical boundaries.”

  The word hung in the air. Neither of them seemed convinced.

  Back at the apartment Lian cooked rice. Simple. Familiar. The kind of thing that grounded her.

  “You still cook like we might leave mid meal,” Kai said.

  She stirred the pot. “We might.”

  They ate in silence.

  Afterward Kai said, “I can get closer. Digitally.”

  “Do it slow,” Lian replied. “No alarms.”

  “I know,” he said.

  That night the doctor returned to his lab. The lights were low. The equipment hummed softly.

  He reviewed the notes again. Adjusted a parameter. Recorded a result.

  His phone buzzed.

  Unknown number.

  He hesitated, then answered.

  “Yes.”

  “You did well today,” the voice said. “The committee is satisfied.”

  “I was told there would be oversight,” he replied.

  “There is,” the voice said. “We are watching.”

  He hung up and stared at the dark screen. For a moment he considered deleting everything. Just walking away.

  Instead he turned back to the bench.

  The work made sense. That was the problem.

  Two days later Kai cracked a door.

  “Got something,” he said, eyes bright. “Secondary server. Not hospital. External but routed through their network.”

  “What is on it,” Lian asked.

  “Scheduling. Deliveries. Test groups.”

  She leaned over his shoulder. “Names?”

  “Codes,” he said. “But I can map them.”

  “Do not yet,” she said. “I want context.”

  He paused. “You think it is him.”

  “I think he is involved,” she said. “I think he believes he is doing the right thing.”

  Kai sighed. “That is always the dangerous part.”

  That evening Lian went out alone. She did not tell Kai where. He did not ask.

  She walked past the hospital. Did not go in. Just stood across the street and watched the windows.

  The doctor was there. She could feel it.

  Inside the lab he froze for a moment. He thought he saw her reflection in the glass. When he turned there was nothing.

  He rubbed his eyes and kept working.

  When Lian returned Kai was still awake.

  “You did not have to go,” he said.

  “I did,” she replied.

  He studied her face. “We are still on the same page.”

  “Yes,” she said. “We watch. We learn.”

  “And if it gets worse,” he asked.

  She met his eyes. “Then we stop it.”

  She lay down on the floor mat. Stared at the ceiling.

  Across the city the doctor wrote a progress report. He chose his words carefully. Made sure nothing could be misread.

  He did not mention the woman who kept appearing in his thoughts.
