Ok, I’ll take a crack at questions 15 and 16 as well.
15. Does Rumpelstiltskin still have his dagger?
16. What is Mr. Gold looking for in the woods?
I don’t think Mr. Gold has the dagger. I’m not sure what happened to it, but I find it odd that he was able to bring certain items from Fairytale land (like the puppets, Belle’s chipped cup), but not the most important item in his possession, the dagger. So, whatever happened to it, he desperately looking for it right now, and that’s where the woods come into play.
In this show, there’s a running theme of everything being burried underground. The box containing the heart in episode 1×15, “Red Handed,” the well leading to the underground lake in episode 1×13, “What Happened to Frederick,” Mr. Gold constantly digging in the woods. Many viewers are even speculating that Fairytale land is burried underneath Storybrook. So, I wouldn’t be surprised if the dagger is underground as well. But the more important question is how did he lose it?
I think Rumpel probably lost his dagger when he was captured by Cinderella and held in prison right before the curse was cast. So, there’s a chance Cinderella, Snow White or Prince Charming have something to do with it as well. I don’t think Regina has the dagger, let alone knows where it is. If she had it, she would have used it already.
Wacky theory: I have a feeling Bae took the dagger and tried to destroy in an effort to destroy to the darkness that was growing in his father.
