In the Scarlet Letter, the two symbolic images of good and evil that battle over Dimmesdale's soul are A. Chillingworth and Pearl. Pearl is his daughter, and she represents the good part, and Chillingworth is Dimmesdale's lover's husband, and he is quite evil.
<em>Indirect characterization</em> is the process how the writer shows the personality of the characters indirectly, not indicating explicitly which actor represents the character, but through speech, actions and appearance. Drama plays usually don't have a narrator describing each character, so the audience has to gather the type of person the character is based on their behaviour.
