Webb saw that, too.
He drew a beer nobody had ordered and stood holding it, looking at the back of the blue shirt, and a cold and certain feeling began to climb up the inside of his ribs, the way the tide comes into a cut you have swum a hundred times and always underestimated.
He did not know her face, but he knew that stillness. He had spent his whole life around the few people who carried it, and he had learned, the hard way, that the loudest man in any room was never one of them.
His hand paused on the tap.
He had seen that stillness before, a long time ago, in men who never raised their voices. And not one of them had ever needed to.
The woman drank her water. The team laughed. And the night, which everyone in the Holdfast believed they understood, had not yet begun.
Cain was not a cruel man, only an unfinished one. And unfinished men cannot leave a thing alone.
He came back down the bar within 10 minutes, drawn by the woman's calm the way a boy is drawn to poke at a fire that will not flare. He set his beer down beside her water with a click and leaned an elbow on the wood.
"All right," he said, friendly now, performing friendliness. "I'll bite. What is that?"
He pointed at her collar, at the small dark pin fixed there. Subdued and worn, no bigger than a thumbnail.
"Because that looks like a trident, and you're not wearing it like a costume, which is what's bugging me. So, what is it? Gift shop? Boyfriend's? You buy it at the base exchange to fit in?"
The woman looked at him then, fully, for the first time.
Her eyes were a pale gray, and they did not move around his face the way most people's eyes move. They simply rested on him and held.
"It isn't a trident," she said. "Look again."
Cain looked.
He was close enough now to see that the pin was not the eagle and trident and flintlock every man in this bar had bled for. It was smaller, plainer. Two crossed shapes beneath a single star. The kind of thing that meant nothing to a man who had never had reason to learn it, and everything to a man who had.
He did not know it.
