Rex hasn't got the faintest clue what the Judge is talking about.

He may pride himself on the breadth of his knowledge, but what that knowledge covers is strictly limited. He has an exhaustive knowledge on the planets he'd been dispatched to, on warfare and strategy, on what it takes to run an army. The roles and cultures of planets that he'd never had any reason to be deployed to are lost to him as are, quite frankly, many of the planets that he had been deployed to. He eyes her suspiciously, vaguely aware that she's come to a decision, but he doesn't know what that decision could possibly be.

Nor that the Imperials employed anyone who could have anything but total loyalty to them. He tenses up, planting his feet squarely on the ground, ready to spring up, for what little good that may do. And spring up he does once she suddenly knocks out the guard, knees bent and eyes wide with bewilderment. He hadn't said anything to even remotely convince her of his plight, so what...

"What are you doing?" His eyes dart from the Judge, to the guard, and back to the Judge. "What's going on?"
