For a split second he has no idea who to address the message to; oh, they have a Thyferra-based comm signal to send transmissions to, which are then manually rerouted on a different comm-board to the appropriate parties under proper encryption. But he can't very well send a standard, encoded message the way he would have had this been, say, the comm on their ship.

Only one person comes to mind, and she will utterly and completely hate him for it for the next forty years, and then tease him mercilessly for the forty after that.

Regardless, he makes a show of trying to contact his "wife" but getting no immediate reply. So he gives a helpless shrug and a wry smile to the techs, and begins to type out a brief text-based message - no need to go asking for full-blown, recorded holo privileges, after all - taking his time until he can sense an all-clear signal from Anakin.

Of course, his minor lingering gets the techs a little antsy, and one of them snaps, "Oy, we said make it short."
