This just may be the way I view it, but in The Wizard of Oz from 1939, it seems like Glinda brought Dorothy to Oz with the tornado. What if Glinda was the one to summon the tornado that brought Zelena and Dorothy to Oz? Also, I'm going to mention this: In a scene where Bae/Neal was in Gold's shop, there was a doll, perhaps porcelain? It looked A LOT like Glinda. It had a rose dress, a high crown like hers, and maybe a long wand. Can anyone get screenshots of that? Maybe Neal really has been to Oz and its foreshadowing?
Also pointing this out: the Black Fairy was banished to a different realm...
