EKK - Am worried for Jack (possible spoilers)
Davy Jones is the main villain in the film Pirates of the Caribbean: Dead Man's Chest (2006), played by Bill Nighy. He appears along with his crew of half-human, half-sea creature sailors aboard the Flying Dutchman. He is portrayed as a mutated cross between a man and an octopus, with a wriggling beard of tentacles and two crustacean-esque limbs. The movie also extrapolates on the origins of Davy Jones. In the movie, the story follows that Davy Jones was once an average sailor who fell in love with a beautiful woman, wild and untameable as the sea. When he could not have her, the pain was so much that he cut out his still beating heart, and sealed it in a chest, so that he would never have to feel love or compassion ever again.

Jack IMO Is going to mirror Davy J more than Will...Elizabeth is probably going to cold shoulder Jack, not Will. Will may be the one to stab the heart but methinks it wont be though heartache of losing Liz
I'm not saying that he's going to cut his heart out...but interesting isnt it how we supposedly learn in AWE (T&T) that Jack begins to truly loathe his most compassionate and loving side of himself...his "honest side"..could this be because people keep hurting him when he shows it and does good things for them because he cares for them?
I'm not saying Liz doesnt care about Jack(scenes from DMC say the opposite)..but she is trying to shut Jack out no matter how much she may want him IMO
PS Jack is not the best sailor..by comparison Will takes better control of the ships than Jack does in the movie..he shows more potential as a great sailor than Jack does.
