You kinda lost me, there, but, if Neal is the White Rabbit, he wouldn’t need a bean to get to Wonderland, he would use the rabbit hole.
Jefferson’s Hat, I think, represents the rabbit hole.
The poison apple falls down through the ‘rabbit hole’ from FTL, but pops up through the Hat in Storybrooke.
Lewis Carroll describes this concept, when Alice is falling through the rabbit hole….she puts the marmalade jar back on a shelf so it doesn’t kill anyone below her, which she thinks is upside down because she fears the rabbit hole will take her straight through to the other end of the Earth where ppl walk upside down.
