Through use of flashbacks and present day clips we go on a journey with Bradley Voorhees to different times in his life. Aside from birthday party hopping we get to know the many different people in Bradley's life through various, little anecdotes he delivers throughout the episode. So, not only do we get to know Bradley in present day, we also get to know who he used to be. With Bradley attending both current day birthday parties and with flashbacks to many birthday parties that he attended in the past viewers should get a well-rounded idea of who Bradley is as a person. Not only does the audience get to know Bradley, but they get to know the many different people in his life, in both present day, and past-time. Though the episode carries a birthday party theme, it isn't all we see. We also see Bradley at a time in his life where he was suffering from the loss of a relationship and family in his past.
