So here is my crackpot theory of the morning. Based on the fact that we see PP’s shadow (and how creepy it is) and based on the fact that thus far apparently none of the fans have guessed Neal’s story yet:
What if Bae went to FictionalLondon right after Rumple let go of his hand, but his shadow went to NL and have been causing problems. In the story of PP, the shadow often has a mind of its own and acts out. PP is constantly trying to track it down. So in H and K’s world the shadow was separated from Nealfire when he went through the bean hole.
Crackpot? Yes. But I got nothing else right now.
