OMG your words made my heart skip. 😱 I believe also that Jack was thinking about staying. He came back for a reason, he knew the kraken was after him not the ship. I think he was considering to stay regardless. But Liz made that decision for him. Its curious because in Tia's hut Will is the one that kinda decides to get Jack back, IMO he was also making that decision for her. Nor like Will, he has proven to be more emotionally stronger than Jack/Liz, he is willing to do whatever it takes, he accepts anything that comes his way. He makes his own decisions, he doesn't let anyone to choose them for him.
