Sometimes, Genre Savvy characters talk about tropes. There are at least three kinds of such discussions: * They invoke the trope directly, either by action ("I'll make my sword more powerful by making it brighter!") or by anticipation ("His sword is glowing, I suppose that means it's very powerful"). * They're just discussing tropes in general, apropos of nothing. This is also called Conversational Troping. * And then there's the discussions that go something like, "If this were an action movie, talking about your family like that would mean you'd be dead in a few minutes." or "Unlike what you may read in detective stories, the Butler is a somewhat unlikely suspect in any murder investigation of this sort, for reasons X, Y and Z."
