Davy Jones has a pawn shop down there
one word "senile" =I
she is throwing her 'sexuality' (her Jewel) to Jack in an ex<x>pression of loyalty and love
I just thought it was stupid!!
nothing, she was insane.
She didn't want to live of Cal's money. It was her way of letting go and keeping her promise to Jack.
It was closure for her...and it was where it belonged
who cares, its a movie
She sent it down to where it belonged. With the expiriances on the ship. And the dreams she had! In her view thats where it belonged!
It was a sacrifice to Poseidon, by which she survived while abandoning her one true love (that guy she's just met and ******** for--you know how deep those relationships are)
To part ways with her old life and leave it there so researchers can find it later and fight over it's value.
