I didn’t say he didn’t know anything about Oz. Clearly he does–but I’m suggesting it’s culturally not life experience. He knows ruby slippers exist as portal makers but that’s from the movie, not actually being in Oz and knowing Dorothy because we *know* they can’t use the ruby slippers. He knows that the Crystal Ball might help him because the WWW used it in the movie to see Dorothy and then show Dorothy Auntie Em but has no idea how to use it, try though he might.
Agreed. They even made a point of giving Neal lines about having watched movies (Mulan), then had him mention ruby slippers, but we know the actual slippers in the show aren’t gonna be ruby, he just got that idea from having watched the movie IMO, not first hand Oz experience. Even if he hadn’t seen the WW using the crystal ball in the movie, general crystal ball basics are a general thing that everyone knows – you look into them and they let you see stuff.
