The story begins with and is enveloped by Walton?s letters to his sister. His sister is very close to him; as can be seen by the affection terms used for her and the comfort level that Walton has with her; terms such as ?dear sister? and ?my sister?. This relationship that Walton has with his sister is placed on the reader through his expressions and use of language.
The reader is forced into the role of a character that already has some developments. Walton?s sister is a character that exists prior to the story; this can be seen by the way Walton treats his subject. Because the reader is the audience with her, the reader is pushed into that role, but not to become a part of the story, only to develop the relationship with Walton.
