Although the text of the story you are referring to is not included with the question, we can still try to determine what the use of flashback normally accomplishes in a text.

A flashback refers to an interruption in a story. In this interruption, an author inserts past events in order to provide background information that allows the reader to understand the story better. Therefore, there are several things that a writer might want to accomplish by inserting a flashback in a story. He might want to provide more information on a character. He might also want to allow the reader to better understand the context of the story.
