The Wizard of Oz references may not mean we will see a Wizard of Oz scenario but quite simply a hint of a strategy to take. The Wizard of Oz story may be an Art of War for fighting Fairy Tale Villians. The trio does really need to first find out who they are up against and how many? Next they need to know who is on their side and how they can help? Then if the WoO is just a plan and not a hint of an up coming episode then the trio plus whoever is on board should make that happen.
