First there is Desire
Obi-Wan
"Obi-Wan, train the boy. He...he is the Chosen One."
"Yes Master," was his heartbroken reply. A final fond touch and then the Living Force within was spent.
It was his Master's last words, his dying wish. He would adhere to Qui-Gon's desire of training the boy. It was immensely important to Qui-Gon - so important that his Code bound protege was willing to defy the Council. Something that he had not been willing to even to entertain since Melida/Daan, over a decade ago.
"What will happen to me now?" said a small scared voice, sorrow drowning apprehension, shattering the solemn silence. He turned and regarded his new charge.
"The Council have granted me permission to train you. You will be a Jedi - I promise you."
With that, he turned back to the flames that consumed what was left of his beloved Master.
He knew he needed to let him go. Qui-Gon was now one with the Force. And the Force was always with him. That was a comfort at least.
There were other things Obi-Wan needed to let go. In the coming days and years, Obi-Wan would desire to hear Qui-Gon's voice again. He wished he could hear his wise counsel, feel the touch on his shoulder, even a playful tug on his now shorn Padawan braid. He desired to hear Qui-Gon say that he was proud of him.
His deepest desire? He longed to hear that Qui-Gon loved him as a son, just as Obi-Wan loved him like a father.
