(Note, possibly NOT to actual movie speech, more or less what COULD of happened).
James Norrington paced in his cabin after learning that Elizabeth had suddenly taken command of Sao Fang's ship, and as such a perhaps mere seethe of jealousy sparred through his teeth but yet was countered by a sudden infliction of worry. How was he going to deal with this situation? Fingertips tapped against his old glory and he knew what he must do – free Elizabeth, and perhaps sacrifice himself in order to do so.
He'd chosen the wrong side, and for what? A fancy outfit and title that meant nothing to him now? He'd lost Elizabeth purposefully of this reason, Admiral was a fine title to behold but alas... it discouraged him. Beckett was the wrong man to serve and although he despised the Jack Sparrow order as he called it, a part of his mind wondered if it were best to follow him.
He pulled a piece of parchment from a drawer in his cabin and started to write, a letter, a final word, to someone that he cherished perhaps moreso than Elizabeth. He pocketed the letter and exited, only to catch her in arms width of leaving.
"Elizabeth", he said her name in the famed single breath that he hoped would have captured her heart those years ago, before she found... Turner, and skipped off to become a valiant Pirate in his name.
She had frozen, gripping onto the rigging in a mild attempt to release a life boat free. Elizabeth turned, her few strands of hair blowing in the air lightly. She leapt down and gave James a look of relief, but yet it was confused with fear – so he noticed. The crew were sleeping, so he believed, and so he enveloped her in an embrace, suddenly wondering what on earth he could've done to capture her heart.
"James", she said his name and he pulled back, looking at her as if to read her thoughts. "I've got to leave".
"I know". He answered, defeated. There was no way that he could simply win her heart after all that had happened, she had seen many sides of him and the side that supported Beckett was not one to muster. "I am sure your father will be proud of you".
Elizabeth shot him a cold look in mid turn as she paused a mere meter from him. "My father is dead". She said this knowingly, accurately, and James felt a lump form in his throat.
"No, he's gone back to England..." James tumbled on his words, struggling to find something but inwardly he knew Beckett had been jealous of Elizabeth's father since day one. No doubt Swann had been foolish enough to sign his own execution order.
"Did Lord Beckett tell you that?" Replied Elizabeth coldly, the mere stare making James want to turn back time right there and then. Still he stood firm, eyes closing somewhat, when he suddenly heard a noise. No, a crew member had awoken... was that... Turner's father?
"Go", He told Elizabeth, pulling something from his pocket. "Take this".
Elizabeth grasped the envelope and gave it a once over. "Why?"
"For my sister. Please". James brandished an arm in order to protect her, the other arm holding out his sword as Turner and a few other crew members lurched forward. "Just go, Elizabeth".
Elizabeth hesitated, gripping the note and putting it in a pocket, as she jumped on a life boat that had since been filled by a few of her crew mates. She cut away at the ropes with a dagger, when suddenly she saw James being circled by the Dutchman's crew members and Davy Jones himself.
Elizabeth was out of sight when it happened. James feeling his own sword being plunged into his heart, the life sucked out of him as he lay amongst the barnacles of the Dutchman. The last thing he heard was Elizabeth's pained cry before darkness took him, but alas, no one would be there to save his soul...
