When he calmed down and thought about it carefully, Roy realized that he had made a mistake.
He should not be another transaction partner of Jack Sparrow but the only one!
The real situation was that Jack Sparrow had already looked for Davy Jones once. He had looked for Davy Jones to get the Black Pearl that had sunk to the bottom of the sea! For this transaction, Jack Sparrow had made an agreement with Davy Jones. Both parties had agreed that after Jack Sparrow was the captain of the Black Pearl for thirteen years, he would go to the Flying Dutchman to serve hard labor.
When he made the deal, Jack Sparrow probably did not think too much about it. But to his surprise, after the Black Pearl was salvaged, Jack Sparrow only became the captain for two years before Barbossa successfully betrayed him.
