I'd love to see the boy who cried wolf maybe with Red. I have a feeling she has a back story with Rumple (she's the one who told Snow about him and they share a bit of a look in the first ep).
I'd also like to see something about the princess and the pea (maybe this leads to the creation of the sleeping curse?). And the King's invisible wardrobe would be an interesting story to see what spin the writers could come up with.
**possible spoiler alert**
I know Robin Hood is coming up in the next ep so that'll be fun and they've also alluded to the Wizard of Oz (loved the bit about the red slippers, anyone know what the orb was about?)
What about everyone else?
