Serenity (Firefly Episode) - Arc Significance

Arc Significance

This episode introduces a major story arc of the short-lived series: that of River and Simon. It reveals Simon's deep, selfless love for his sister and that his life is now defined by her.

Despite the script stating that Dobson is killed by Mal, Joss Whedon had planned to bring the character back. Although the series was cancelled, Dobson coming back for revenge was a key part of the plot in Serenity: Those Left Behind, a three-issue comic book miniseries intended to bridge the television series and the movie Serenity.
