Not many stories exist without both voices. On Star Trek it’s the captain’s log. In Flashdance it’s the confessional in the Catholic church. In the film The Social Network, the big voice expository sequences are the legal deposition scenes. At regular intervals a character is going to discuss his life with a therapist. Or she’s going to write a letter or diary entry, but she’s going to rise above the meat-and-potatoes reality of physical verbs.
