Then she flashed the immaterial pointer four balls further along the string. "And here's where they attacked us. When they appeared, they didn't give the impression of a force that had just piled into the system and was still in the process of getting itself organized. That's why I believe they entered a closed warp point in one of the intervening warp nexi." She created the broken strings that denoted warp lines leading to closed warp points, indicating hypothetical routes into the three nexi they'd transited before the Bugs had overtaken them.

"Precisely," Kabilovic said with a satisfied nod, but Murakuma wasn't finished.

"But the question then becomes," she went on, "why did they wait so long to attack us?"

"Well," Hafezi ruminated, running his fingers through his beard in a nervous gesture he'd only recently acquired, "we were operating in cloak. Even if they were aware of our presence in a general way, maybe they took a long time to locate us precisely."

"But, Sir," Murakuma persisted, "it wouldn't have taken them long to do that if they'd come out of cloak themselves to hunt aggressively for us. Maybe they were unwilling to do so."

"Why?" Sommers demanded.

"Well, Admiral, if we'd become aware that there were Bugs in this warp chain, wouldn't our first order of business have been to get at least one ship back with the warning? And with them out of cloak, we might have detected them soon enough to do just that. So it could make perfectly good sense to them to stay cloaked to keep us from doing that. But," Murakuma continued relentlessly into what had become a profound silence, "why did they suddenly stop worrying about it?"

She made further adjustments, expanding her display to include the warp line of the far side of Anderson One, leading to Alpha Centauri with its eight other warp points, one of which connected with... Sol.

She said nothing. Nothing was needed. They all sat, no longer a staff but rather a collection of individuals, each alone with his or her own horrified speculations.
