Possibly, regarding Killian. That will probably be one of those plot points that remains a mystery.

And interesting point regarding Excalibur. Maybe it wasn't supposed to disintegrate, but Rumple managed a bit of hocus pocus to make it look like it disintegrated, meanwhile transporting the entire sword to some other location, where he then proceeded to snap off the Dagger portion, restoring things to the previous status quo. Of course, how he managed the hocus pocus when he has no magic is still debateable.

As for the rest of excalibur, Rumple's either hidden it in his vault, or maybe it returned itself to the stone. Which is probably still in Emma's basement.
