There has been a lot of speculation as to who her father is, and some have even considered that Rumpelstiltskin might be him because of the similarities between the two. Along with Zelena's father, the identity of the Wizard of Oz will also be revealed. Whether or not the two are one in the same is yet to be known.
This Sunday's episode is going to be a fairly important episode because Regina and Zelena are going to have an old West style showdown in Storybrooke that could mean several possibilities and outcomes for the citizens of Storybrooke. Regina is going to be attempting to help Henry get his memories back, and Zelena could have a huge part in why he may or may not.
While fans now know that Michael Socha is joining the cast of "Once Upon a Time" in season four, some have wondered whether or not that would mean that the "Wonderland" story line would be incorporated into the original show, Adam Horowitz says that "Once Upon a Time in Wonderland" was only meant to be a one year project and the story is now finished and will not be coming to Storybrooke.
Wonderland was once apart of "Once Upon a Time" which is how we found out that Cora was the Queen of Hearts. The story would simply not fit into plans for the upcoming season.
Do you think that the Wizard or Zelena's father could be coming to Storybrooke or will it be a flashback that could change the course of things in town?
