Sorry to start you off with such a sad story, but in the end (as you'll recall) it is a tale of survival, perseverance, and success.
It had been dark when the mutiny took place, so no-one loyal to me would know what was going on until Barbossa was in charge. I didn't even know what was happening myself until it was over. Completely, absolutely blindsided. And yet, in retrospect, it seemed so obvious. Myriad signs... and I had missed them all.
It was dark still, no moon illuminating the nightly sky, and the stars largely hidden behind massive clouds. When I'd swum to the island and turned around for a final look at my beloved Pearl, I couldn't even distinguish her silhouette. All that indicated her position were the lights burning brightly in the captain's quarters - my quarters, my home; its hospitality uncaringly given to another now. It was all that could be seen in the darkness; the one beacon I had, and it only served to underline my loss, my death. I was still breathing, true (though how much longer I couldn't guess, nor did I want to reflect on the matter), but I was no longer a part of my own life. Slowly but surely the lights became smaller, until they disappeared completely, and all was black.
Then a red line, growing ever brighter, defined space once again. As the sun rose, the horizon became more and more visible, until the world had finally re-appeared. The horizon; my everlasting aim. I'd chase her and she'd run away, playfully, teasingly. One day, I knew, I would catch her, and the thrill of the game would be replaced by calmness and reminiscence about the good times we'd had. Now she was right there, waiting for me... and I had no means to get to her. My final goal, just beyond my reach. It should have been depressing, but it wasn't. Somewhere deep inside me dawned the realisation that the game was still on. The infamous Captain Jack Sparrow was not dead yet.
I looked down at myself, and noticed that I was still at the spot where I had arrived on the island. How long had it been? How many hours had I been standing there? I shivered and suddenly felt very tired, drained... A few stiff steps took me off the beach and into the shade, where I sat down against the trunk of a palm tree. One last look at the horizon as I pushed my hat over my eyes. She was still there.
I'll be with you later, love.
