Neal did know about Blood-magic, but then it sounds like a concept that is just part of knowing about the fairy-tale world. The shoes reference though was a bit more odd.
I forget if this thread but the globe that Cora gave Rumple and the crystal ball are two different magical items. Rumple might have magically transported the globe off Hook’s ship after they returned from NL, but then with the reverse-curse, it probably wound up in the Dark Castle, which is where the crystal ball is.
I wonder if we will see either of these objects soon, and if so, if these items have a tie to Zelena, even if Neal himself doesn’t. Cora got this globe from somewhere, and it sounded sort of legendary–what if Zelena had it and wants it back?
“If I had a world of my own, everything would be nonsense. Nothing would be what it is, because everything would be what it isn't. And contrary wise, what is, it wouldn't be. And what it wouldn't be, it would. You see?” -- Lewis Carroll, Alice's Adventures in Wonderland & Through the Looking-Glass
