3) If Jefferson’s hat can only travel to magical realms, how did he get to Wonderland?
Does Wonderland not have magic? Those hedges seemed pretty magical, as did the food. Jefferson having his head cut off, but then for him to remain alive? Pretty darn magical. I think every world has it’s own “kind” magic, since Jefferson tells Regina that Frankenstein isn’t used to “their” magic. So for Frankenstein, he calls the magic of his world “science” even though that isn’t what it truly is. As the only true science is in our world, with not a single ounce of magic or mysticism to change results.
