What does characterization do for a story? In a nutshell, it allows us to empathize with the protagonist and secondary characters, and thus feel that what is happening to these people in the story is vicariously happening to us; and it also gives us a sense of verisimilitude, or the semblance of living reality. An important part of characterization is dialogue, for it is both spoken and inward dialogue that afford us the opportunity to see into the characters' hearts and examine their motivations. In the best of stories, it is actually characterization that moves the story along, because a compelling character in a difficult situation creates his or her own plot.
