[It does take Astrid a few moments to figure out someone is actually answering her back. By then the little device is on the ground in the grass nearby, and she picks it up and peers at it for a few moments before she sees the...tiny person...on it.

So for several moments she just stares at the man on the screen as if she's trying to figure out what sort of magic stuck him in there. She even turns the little device around a few times as if checking to see if he's somehow standing behind it. And then she sighs and rubs at her forehead.]
