It may be that Regina got the apple from somewhere else though and not from fairytale land originally. In True North the Queen tells Hansel and Gretel that the Blind Witch stole the apple from her. I have always thought that Regina was just lying to the children to get them to go get the apple for her, but maybe Regina did get the apple from somewhere else and then it was stolen from her by the Blind Witch. I don’t really like the idea based on how Regina was acting in that scene, but it is still possible.
So in the next episode maybe Jefferson goes through to another land to get the apple. I would rather he went to fairytale land though just because i want to know if it is still there, but at least we will get some information about the other lands.
