Let’s think outside of the box for a minute. These producers use to write for Lost and I very sure that this show is not their first rodeo. The Wizard of Oz can be just a red herring. Look at how many theories have come from just a few pictures and none really make all that much sense. Every plausible one has a plausible conter to the theory. The one that I will go with is that the Wizard of Oz story is just and should be just used by the trio of Emma, August, Henry and any other person they can get to their side as a game plan to fight the “evil empire” and defeated them once and for all to bring back the happy endings.
