So summing up theories on episode:
 * Johnathan is David's father therefore related to Zelena
 * Morpheus or Belle is changeling.
 * Black/Dark Fairy
 * Some connection to Fairy Godmother

I want all of this to happen! My two cents. It's about Belle being a changeling making her Thumbelina. Anyone?
