We found Sophie on the sidewalk where we'd left her. She came into the kitchen when Ruth called her, though she kept her coat on, like she didn't plan to stay.
Grace looked at her granddaughter for a long moment. Then she said, "Tell Daniel what happened. All of it. He needs to know what his roof has been carrying."
Sophie sat at the table and put the old tablet down between us.
"Three months ago," she said, "I got a message from an unknown account. It said my father was alive."
"A prank?" I asked.
"That's what I thought. A cruel one. I almost blocked it." She glanced at Grace. "Then the account sent a childhood phrase. Something only my father knew. Something he used to say to me when I was little."
"What was the phrase?" Ruth asked.
Sophie shook her head. "I'm not saying it out loud. It's mine."
"Fair enough," Ruth said.
"I answered," Sophie said. "He arranged a video call. He told me he was trapped inside Sentinel. He promised to expose everything. He told me not to tell Grandma."
"You obeyed him?" I asked.
"For two weeks." Sophie's fingers traced the edge of the tablet. "Then he asked me to copy a file from Grandma's old computer. He said it was important. He said not to open it, just copy it."
"That frightened you," Grace said softly.
"I stopped answering after that." Sophie looked up. "I didn't tell anyone. I just β stopped."
"And Sentinel detected the contact," Simone said.
Sophie nodded. "A week later, everything changed. Grandma thought I moved here because of the school incident."
"You didn't?" I asked.
"A Sentinel vehicle followed me home from school. Twice. I told Grandma I needed a fresh start." She looked at her grandmother. "I'm sorry I lied."
Grace reached across the table and covered Sophie's hand with her own. "I know."
"The relocation review," Simone said. "Your name was placed under it."
"I found that out later," Sophie said. "After the livestream."
I leaned forward. "The anonymous link. The bedroom feed."
"It was him." Sophie's voice stayed steady, but her hand tightened under Grace's. "He intentionally let me see the camera angle. He wanted Grandma to trace it."
"So he used her fear," I said.
"He was trying to warn us."
"He could have said 'leave the house,'" I said. The anger surprised me β it rose up sudden and hot. "He could have called the police."
"He said they monitored everything."
"He still chose to show you someone watching your bedroom." I looked at her. "You were sixteen. He let you be frightened in your own room so your grandmother would look up at a roof."
"Did you tell anyone at the time?" Ruth asked. "A teacher? A friend?"
Sophie shook her head. "He told me not to. He said Sentinel would know. And after what I'd seen β the schedule, the alarm code β I believed him. I believed they were everywhere."
Sophie's expression tightened. I understood her desire to defend him. The man on the tablet was her father, alive, after eight years of a grave.
"I also understand the cost of his method," I said, quieter.
Grace spoke then, her voice rough. "He had learned to treat fear as a tool. Perhaps that was what eight years inside Sentinel had done. Perhaps it was what he had chosen to become."
"Do you believe he was trying to help?" Ruth asked Sophie.
The girl was quiet for a long time. The tablet sat between us, dark.
"I believe he thought he was," she said finally. "I believe he thought scaring us was the only way to make us look. And I believe he was wrong about the price."
"Why wrong?" I asked.
"Because I had to learn that someone was watching me sleep before I learned that my father was alive." She looked at Grace. "He took those in the wrong order."
Grace squeezed her hand. The kitchen clock ticked once, loud in the quiet, and I noticed the casserole dish Grace had brought over months ago still sitting on top of my refrigerator.
"And the worst part," Sophie said, "is that it worked. Grandma found the camera. The network went dark. Everything is happening because I got scared." She paused. "He made fear do the work of truth. And it did work. That's what scares me most."
Nobody had an answer for that. The kitchen was silent except for the refrigerator humming β an ordinary sound in a day that had stopped being ordinary hours ago.
Simone stood. "We need to activate the node," she said. "Whatever Peter prepared, it's time."
