I suspect we'll be seeing a Zelena-based episode soon -- maybe episode 6 -- that will introduce "The Witch" as someone from Oz (not necessarily Mombi BUT PLEASE BE MOMBI), ending in Zelena banishing her and fulfilling the prophecy from Season 3 (and possibly revealing herself as Savior but I think I'm getting too far into my own personal headcanons for this to be likely lol) but she ends up in the Enchanted Forest II with Henry and Cindy to cause more havoc.
