What do you think about the weapon? Do you have any ideas of what Hook might have brought over?
Or do you think he is after the dagger?
Can Rumple be killed whilst in his Storybrooke human form? It’s possible that the Dark One originated from a diffferent land because Blue Fairy told Bae that Rumple’s magic didn’t belong in the land (I can’t remember the exact line). Perhaps Hook spent his time in Neverland researching the Dark one and has found a way to kill him. The dagger may not be the only way.
