Betty didn't know what to expect, coming here; now she doesn't know exactly what it is she's looking at, besides that it's shaped more or less like a chair for some kind of medical or dental procedure. It's mostly black, very solid-looking, it has the assorted scratches, dints and imperfections of a piece of equipment that's both well-used and kept in as close to perfect working condition as possible, and that beyond the general shape it has a lot of . . . extra stuff attached. All over the place. But especially where arms and legs would go.
Betty doesn't see it, or maybe her brain refuses to see it, until Bruce says, "Those are restraints." He says it quietly, saying it to her instead of to the room in general. "Heavy-duty restraints."
