I think like many fans that Hook died in the confrontation of Emma and Merlin in Camelot. Emma brought him back to life but the price of the magic was to embrance the darkness completly that's why she became the Dark One and to make it permanent she also needs the Excalibur. Since Hook's gonna find out what actually happend in Camelot and still wants to get  the darkness of out Emma he won't let her finish her plan whatever it is and sacrafices himself so Hades comes for him to Storybrook. The next half of the season will be about bringing him back and facing with Hades as a villian of the next arc.
