The show was canceled after only its second season, and the final episode left many questions unanswered. To give the fans closure, the producers wrote a 10-minute epilogue, paid for its production costs out of pocket, and the main cast members agreed to come back and film these scenes without pay. "Road's End: the Final Chapter" answers fans' questions, including the identity of Sam's father, and was released as a bonus feature on the second season DVD.
