So, what if Rumple was successful in separating himself from the dagger. Is the dagger now just an ordinary dagger with no name on it? As he is being separated from it, does a successor’s name magicly appear? Have Hook and Belle seen a new name on it?
And also, Rumple was tricked into becoming The Dark One, as he was unaware of the ramifications. We know the previous Dark One wanted to cleave himself from the dagger, even if meant death. Is life about to repeat itself for Rumple? Will we learn later that Rumple has been tricked by the sorcerer/apprentice who wants to cleave himself from the hat.
Assuming a new name would appear on the dagger, who’s name would magically appear? Could it be Neal and his ashes would suddenly become infused with magic? Would it be Henry, Rumple’s bloodline? Or, could Rumple select his own successor to the dagger.
