Cassian kicks the bag with the rifle into a compartment and snaps it shut, so that it won't be flying around if they have to do any strange maneuvers, or cut the gravity and the engines to drift. He has to brace himself against the bulkhead as they bank, and then he's forward, sliding into the seat.

"You really want to know?" Because he's not sure that Poe does. Besides the confusion and the disorientation that comes from not knowing the plan.

An alarm goes off; Cassian hits it. "Star Destroyer in orbit," he says. That was fast. They must have had a detachment waiting a microjump away. He thumbs two switches on the communications panel. "I have a message queued," he says, to Poe, "and it will lead them straight to us. Tell me when I can broadcast and you can still get us away. And cut it as close as you can."

The message, of course, uses a weak encryption that the partisans on the planet use for short messages. It's a standard distress call, but it'll do two things, one of which is purely to make Cassian feel better: first, it'll continue the frame job from what Cassian left on that hill, and second, it'll draw the bulk of the First Order activity away from the civilians.

And towards Poe and Cassian.
