The second and third parts are a story, and everyone has his own abacus. Jack hopes to get david jones's heart, so that he doesn't have to work for him 100 debt. He knew he couldn't kill david jones, so he would lose his freedom. He hoped to exchange his father Bill Turner's freedom for david jones's heart, and even wanted to cooperate with the East India Company. Besides, he thinks Elizabeth is jealous of Jack because of the second part. Everything Jack did was for his own freedom. Everything Will did was for his father's freedom.

Then Elizabeth II ended by saying that Jack was a coward, but Jack didn't want to admit it, and that Will was a coward.

Jack pushed Will into the sea, because Will wanted to leave a signal to the East India Company, which was the venue of the Cutler Beckett Piracy Conference. . . Cutler Beckett wanted to catch the Pirate King. Then Jack found out, gave him his compass and pushed it into the sea, because Jack's compass can lead the user to find the things and people he wants most. What Will wants to know is the location of the pirate meeting. Jack deliberately asked Verdi to leak the compass to Beckett, so that the pirate kings could collectively attack david jones. If some idiot kills david jones or he gets the heart, he will be free. . I just didn't expect david jones to know that Jack didn't dare to stab Will in the heart without being threatened.

As for why Elizabeth was on the boat in david jones, it was because Feng Xiao thought Poseidon had brought her to her boat. As a result, the ship was attacked by david jones and Feng Xiao died. All the crew on board, including her successor Elizabeth, were naturally arrested.
