Thrawn just barely refrains from activating the alarm as he stumbles toward the wall, sagging against it for a moment while the shuttle hesitates. This would be very poor timing on his part, and that is not to be borne.

Once the shuttle is fully away, however, he gives it a count of thirty before he activates the alarm. Then, expression composed (if a little strained) he moves to find replacement comm gear and begin giving out instructions on how to entirely fail to capture Hera Syndulla. It will be an interesting challenge, and he finds himself wondering how much, exactly, Vader will understand.

Not that it matters. Not this time.
