Resurgent-class Battlecruiser gets an eyebrow raise out of Cassian because that? Sounds like Poe was about to be executed, honestly, and now he has questions. Questions which, fortunately, can wait.

Besides: "There are worse things than being a stormtrooper," says the man who died in an Imperial uniform, the remnants of which remain in a box beneath his bed. He suspects that stormtroopers believe, or are coerced into believing. So Cassian shrugs. It's accepted.

For now, anyway.
