Oh good. Soundproof glass. John points to his mouth to see if the kid can read his lips. "We need a code to unlock the door."

He waves a hand around to the mess of stuff behind him. "It is somewhere in this stuff! Find it."

John hopes he's understood because the water hasn't stopped rising. They won't have much time and he doesn't have what he needs for a water breathing spell. And he doesn't really fancy seeing his father in the water or hearing him.

He turns away to start searching again. Hopefully to find something thhis time instead of just more nasty notes and painful reminders.
