After staring at her a long moment, he slowly walked over to the door, more backing away to keep looking at her, uncertain if he was going to make his mouth say the 'one second, hold that thought' or not, or if maybe she would pick up on what he was.

He hurried back in, staring at the wall in confusion.
"Uh. We... might actually want to seriously wonder what the previous owners hid behind the walls," he said slowly.
