Idea: One of the clones who subsequently names himself Jedi is born with the ability to use the Force.
He had always been different. Though he looked like all of his brothers, with the same dark features, the same jet black hair, and the same dark eyes, there was something about him that wasn't the same. For the first ten years of his life, he hadn't known what it was.
He had spent his entire childhood (if you could call it that) in fear. He had been afraid that the Kaminoans would notice the difference and deem him defective. While his brothers had known he was different, the Kaminoans apparently didn't notice. To them he was just another face in a sea of faces.
To his brothers, he was the odd one that knew what was happening before it happened. The one strange things happened around. He was something else and his brothers knew it.
It had been shortly after the battle of Geonosis when he had learned what his difference was, and that had he been born someone else, he could've been one of the Generals.
The brown robed Jedi had looked at him in surprise when he first saw him. Over the next few days, before the Jedi died, he learned about the Force from him.
He, though an anonymous clone, had been born special. He was something other. He had found his name.
He was Jedi.
