I have noticed that the most prevalent theory for the final episode will involve a carjacking witnessed by the four with their failure to report it. Unfortunately, I must take a small step into the fray and assure you that the final episode does not have the carjacking theme. It is with careful thought that I decided just to share a small part of the knowledge I have received from an insider with the show, that will remain unnamed. The carjacking idea was originally thought about for the final episode, but was overruled by producers. They didn't want the show to end on a memory lane stroll. Be assured that this whole concept was developed for the primary reason of leaking disinformation to the press and others. That is all I can say about it.
