[Ford comes up the stairs last, and looks around the room with no small amount of curiosity. It's disgusting, yes, but at least there are no dead bodies!

He looks at the item Elsa is holding up, and his face lights up.]

[He takes the tape recorder and look it over, punching the buttons experimentally. Is it still functioning?]
