Characterization is “the creation of imaginary persons so that they seem lifelike. There are three fundamental methods of characterization:
1) the explicit presentation by the author of the character through direct exposition, either in an introductory block or more often piecemeal throughout the work
2) the presentation of the character in action, with little or no explicit comment by the author, in the expectation that the reader can deduce the attributes of the actor from the actions
3) the representation from within a character, without comment by the author, of the impact of actions and emotions on the character’s inner self”
