At what point during Emma's rescue of everyone did Hook get cut with excaliber, and why did it kill him? Didn't Merlin say its made to cut immortal ties? How did Hook become immortal in the first place? If he's immortal and so old that he would die if not immortal any longer, then why couldn't they cast a preservation spell and have Emma do what she did to revive post DO Rumple?
