Yeh exactly. That whole jack thing sounds right Blackpearl44
If what she really supports is "honor" and "moral standards", then why do her actions in that scene show the complete opposite? Answer: Its not what she really stands for deep down and its not what she really wants from Jack. She wants a taster of HIS lifestyle. Its all a coverup.
It shows that all her "stuck up, I'm above you" "you want to do the right thing" speeches to him are all just an ACT/denial. They are her desperate attempts to cover up what she really wants from Jack.
I also notice that her gaurd drops a little bit more with every Jack/Liz moment during the movie.
The first time where he suggests sex to her..she coveres it up well with a look of disgust "I would NEVER i'm to honorable for that!"..but secretly smiles when she thinks no one is looking
The second time, she pretends that she means one thing when she really wants another and almost kisses him. She still manages to save herself from what she just did by saying "I'm proud of you jack" If she had kissed him right here..then I DOUBT she would have chained him to the ship later on..the kiss was intterupted for that reason. It was meant to be there where she finally gave in..but it was stopped. Which made the temptation build up a whole lot more andit exploded later on with drastic conciquinces.
The final time..She gives into it completley. It was overdue and building up throughout the entire movie (that may be why her actions where so drastic)..all temptation building up finally overtook her, made her cross the line. She tries to cover up by saying "I'm doing it for the others" But No..it doesnt work this time..she gives in, all the denial is shed and she says "I'm not sorry" (NOW THATS A TRUE PIRATE) she wants to be officially called pirate by Jack before she goes.
