We do know that Rumple’s been there before or has some connection to it- Adam and Eddy stated as much. But I suppose Regina *could* have been before- perhaps through Jefferson’s hat. I guess we will have to see.
For what it’s worth- here is an excerpt from the stage version of Peter Pan in which he discusses fairies, the lost boys, and Neverland. 🙂 Obviously, OuaT isn’t restricted by the original story frame, but I thought you all might enjoy it.
