The watchtower was quiet between them with the city below and the wall below that and five blocks southeast the things that could think sitting in whatever remained of the park and watching the building with their unblinking attention.

"They can count," Michael said.

"They can observe and respond to what they observe," Cole said. "Whether that’s counting or a cruder version of the same thing I don’t know. But they moved when the building appeared less defended and stopped when everyone came back." He paused. "That’s not instinct. That’s strategy."

Michael looked at the signatures for a long moment.

"Defense meeting at ten," he said. "I need you in it."

"I’ll be there," Cole said and went back to looking at the city and Michael went down to find Gareth.

---

The meeting happened in the apartment with six people around the coffee table and the Blueprint Interface overlaid on the space above it that only Michael could see but that everyone had learned to interpret from the way he looked at and gestured toward empty air.

Michael. Cole. Gareth. Dr. Kang. Sera. And Anya because her supply and logistics assessment was going to matter for whatever the defense timeline produced and Michael had learned that leaving Anya out of planning meetings cost him things he didn’t find out about until later.

Gareth sat across from Cole and the two of them had not been in a room this small together before and the air between them had a quality that wasn’t hostile exactly but was two people who had independently assessed each other and arrived at a mutual wariness that was honest if not comfortable.

Michael put the threat picture on the table the way he put everything on tables, directly and completely.

The Aberrant group. Five blocks southeast, forty seven to sixty individuals, cognitive function retained, coordinated behavior, strategic movement timed to building population levels. One block closer since the wall completed. The patience of it.

The variant Stalker. Dr. Kang’s findings on the body. Sustained speed, structural reinforcement, extended reach. One escaped north. Unknown population size in the northern blocks. Unknown relationship to the Aberrant group.

The timeline. The Aberrant movement pattern suggested deliberate approach with assessment stops. Based on the current pattern the next movement was due when the building presented a reduced defense profile again. The variant Stalker unknown.

He laid it out and let it sit and looked at the room.

Dr. Kang went first. She covered the biological findings with the precise economy she brought to everything, no speculation beyond what the evidence supported, no softening of the implications. The virus convergence theory, stated clearly as theoretical and clearly as alarming. The training implications for the variant Stalker contact profile.

Sera listened to the training implications section with the specific focused attention of someone updating an internal model in real time. "The inside reach principle still applies," she said when Dr. Kang finished. "But the approach window is shorter. You need to initiate the inside move earlier in the Stalker’s approach which means committing before you have full information about the attack direction."

"Counter," Cole said. It wasn’t a question, he was asking her to continue.

"Elevated position helps," she said. "Height changes the approach geometry and forces the Stalker to adjust which buys time. Maya’s turret control gives us elevated coverage. For ground level contact the answer is group coordination, two people minimum on each variant, one drawing the approach and one taking the inside move on the opening." She paused. "We’d need to train specifically for it."

"Starting tomorrow," Michael said.

Sera nodded.

Gareth had been listening to all of it with the no-easy-look version of his attention and now he looked at the table and then at Michael.

"The Aberrant timing," he said. "They moved when we went outside the wall. They’re monitoring the building population." He looked at Cole. "The clearing operation pulled most of the building’s capable fighters outside simultaneously. If they’d moved at noon instead of stopping at five blocks they could have reached the wall before we came back."

"They didn’t," Cole said.

"They didn’t this time," Gareth said. "They’re still assessing. They’re not ready to commit yet." He looked at Michael. "Which means we have a window. Not a large one and not a permanent one but a window where they’re still gathering information and haven’t decided to act on it."

"How do we use the window," Michael said.

Gareth looked at the table. "We stop giving them useful information," he said. "The clearing operation showed them our full force composition and our movement pattern. We shouldn’t do that again. If we go outside the wall we go in small groups with staggered timing so the building never appears significantly reduced." He paused. "And we vary the routine. They’re observant. If we do the same things at the same times they learn the pattern and they use it."

Cole looked at Gareth with the wariness still present and something else appearing alongside it that wasn’t wariness. "Agreed on all three points," he said. It cost him nothing to say it and he said it simply.

Gareth looked at Cole briefly and looked away.

Anya had been quiet through the meeting and now she put the clipboard on the table and looked at Michael. "The supply implications," she said. "If we stop large external operations the supply acquisition rate drops. We have three weeks of comfortable stock at current consumption. If the threat picture forces us to reduce external runs significantly we need to know what we’re managing toward."

"The greenhouse comes online fully in ten days," Michael said. "That covers the caloric baseline if we manage it correctly." He looked at Anya. "What’s the gap between greenhouse output at full production and current consumption."

She looked at the clipboard. "Twenty two percent," she said. "We’re short twenty two percent of caloric needs from greenhouse alone at full production. The stockroom find covers that gap for approximately six weeks after the greenhouse is running." She paused. "After that we need external acquisition again."

"Eight weeks total then," Michael said. "Before supply becomes a forcing function."

"Eight weeks at current population," Anya said. "If the population grows the timeline shortens."

He looked at the table and ran the numbers and looked at the Tier 4 blueprint list in his vision and at the underground expansion and the advanced turrets and everything on the list between now and eight weeks from today.

"It’s enough time," he said. "If we use it correctly."

The room looked at him.

"Advanced turrets today," he said. "Blast walls this week. Underground expansion next week. Parallel to that we retrain for the variant Stalker contact profile and we change the external operation pattern to staggered small groups." He looked at each person at the table in turn.

"The Aberrant group is going to commit eventually. When they do they’re going to hit the wall and the turrets are going to do significant work and whatever gets through is going to meet the blast walls and whatever gets through that meets us." He paused. "We build every layer we have time to build and we make sure every person in this building knows exactly what their role is when it happens."

The room was quiet for a moment.

"What’s the turret timeline," Cole said.

"Today," Michael said. "All day. I need your group on materials."

Cole nodded.

"The training schedule," Sera said. 𝓯𝓻𝒆𝙚𝒘𝓮𝙗𝓷𝒐𝓿𝙚𝒍.𝙘𝓸𝙢

"You set it," Michael said. "Starting tomorrow. Full building, twice daily, variant Stalker specific additions."

She nodded.

"Gareth," Michael said.

Gareth looked at him.

"The external operation pattern changes. Staggered small groups, varied timing, maximum four people per group." He held Gareth’s gaze. "I want you designing the new pattern. Routes, timing, composition. Based on the threat picture Dr. Kang and Cole have laid out."

Gareth looked at him for a moment. "You’re giving me the external operation design," he said.

"You’re the one who identified the timing problem," Michael said. "Design the solution."

Something moved across Gareth’s face that passed through several things quickly and settled somewhere that Michael hadn’t seen before on him, something that was neither the easy look nor the thing underneath it but a third version that was quieter than both.

"Alright," he said.
