At one point, as you might recall, we get the Doctor's story, in which he's actually brought to Regina by Rumple to try and revive her dead lover in the Enchanted Forest world. In the same ep, they end up musing about the fact there are obviously other, different worlds, accessible by Rumple and Hatter's fancy hat portal thingy, and that the doc isn't even from a fairytale. I sort of got the impression they'll take that further at some point, but no one mentioned it again xD But really, imagine the possibilities, especially possible dangers and villains!
