With Jones finally dead, Will became the captain of the Flying Dutchman, meaning that the responsibility of ferrying deceased souls to the afterlife.
No longer able to live with his new wife Elizabeth Swann anymore, they consummated their marriage before he left to fulfill his nautical duties, and the curse only allows him to reunite with her once every 10 years.
Will Turner spent most of the original Pirates of the Caribbean trilogy as a normal human (well, aside from his blood being able to break the Black Pearl curse), but near the end of At World’s End, he was mortally wounded by Davy Jones, and the only way to save his life was to have Will stab Jones’ heart and then place his own heart within the Dead Man’s Chest.
Judging by the sip setting in this Dead Men Tell No Tales preview and how integral Henry Turner will be to the story, we can deduce that Henry will see his father again while adventuring with Jack Sparrow on the Seven Seas, but how the father/son reunion will turn out won’t be clear until folks are seated to see the final product.
