[It's the boy. Izunia lets him yell a little bit to get the point across, then turns off speakerphone and jams it against the ide of his face.

Of course, as much as he might try to cover the mike, they're still underwater, sound carries, there's probably still some Church yelling in the background. Izunia's own voice is chipper, in the "oh god please help me" kind of way.]

So! We're over in the eastern section, not too far from the sandbars, I figure if he keeps up this level of noise you'll be able to find us perfectly well once you get close.
