Theory Before Phenomenon

The viewpoint character chats with another character, often a friend or associate, whose ideas seem almost too outlandish to believe. Nevertheless, the seeming crackpot is actually Mr. Exposition and will be vindicated by the story. The exposition doesn't need to be of any practical use to its hearer; its main purpose is to make the strange happenings in the story easier to understand and more plausible for the reader.


 * Type One: After explaining the theoretical background the character proceeds to give evidence. The evidence may be a material object or a story about how he learned what he now knows, for which the discussion is a Framing Device.
 * Type Two: After the explanation, the character proceeds to test out his theory in practice. The experiment will provide results, but may turn out to be more dangerous than the character expected.
 * Type Three: After the explanation, the hearer proceeds to bump into the evidence by sheer coincidence.
