Ok a last shred of hope lol Jack/Liz

yea^^^
Jack came to realize that love is no weakness but the strongest feeling u could ever have. And hes amazed at himself of things he could do and done(fight the kraken)
If he knew that he was gonna "die" and dragged at the bottom of the ocean I think he will be happy knowing that he finally knows what love is and that someone could actually love him back. Again if he ''died'' then he died peacefully knowing that.

I think in movie 3 he would do things that he would never imagine himself doing! Im gonna go off subject just alittle bit:
For example the movie As Good As it Gets with Jack nicholson and helen hunt. nicholsans character was about a dude who had OCD and was obessive germ freak, the type who never steps on cracks(on the floor lol). But then hunts character came in and he fell in love with her, soon he was doing things he never thought he could despite of his OCD.

Jack was a childish person, material lil child person who hid under all those gold, jewels, lucky hat, special coat and sword. And he was the type to runaway and cover only for himself. But ever since liz came to his life he was now risking his life especially to face the kraken. I think he matured right there-that was a new and IMPROVED jack. Despite of his piracy ways he ended up being in love and risking his life for the woman he loves.

Plus he gave up him Precious Pearle for her. To save them all, sure that's what it LOOKED like. But deep down inside, he was doing it because he realized that Elizabeth was right about him having to do something good in his life.

He listened to her, and actually took it into consideration, and he proved himself to her that he WAS a good man and not just a heartless pirate.

He was already doing things that he'd never have done otherwise for dear Elizabeth Swann.
