Can we have an alternative story to your de-aged Obi-Wan ? One where he is found by Darth Vader while he doesn't understand where he is and where is his master (if he is old enough to be a padawan) or where the creche master is
In despair did Qui-Gon watch the interaction between the two male, one so dark that the very air around him was shadowed and cold and the other one of the brightest souls in the entire galaxy. It was all that the dead Jedi Master could do, watch. His Padawan, Obi-Wan, would and could not hear him. The boy, not even thirteen of age, had not yet formed a bond with him and their connection was lost to the Force. Silently, Qui-Gon cursed. For one, the Force that had de-aged the redhead and to an age, where there was no bond and connection between him; and he cursed himself for having been such a blind fool back in his living days.
“Obi-Wan… don’t,” he pleaded, but the redhead, who looked so frightened and lost and small, did not hear him. His ever changing blue eyes were fixed on the form of Darth Vader, former known as Jedi Knight Anakin Skywalker. But that Jedi Knight was gone, replaced by this robotic dark being.
“Come with me, join me,” said the mechanic voice, “and together, we can rule this galaxy.”
Obi-Wan looked unsure, his light was flickering, clearly trying to escape the darkness that slowly wrapped itself around it.
“Padawan, no!” for the briefest of moments, he could have sworn that Vader had looked his way, but it was not the attention and reaction he had wanted.
“I… don’t want to rule the galaxy,” said the redhead eventually. “I want to be a Jedi,” his voice was trembling.
“There are no Jedi anymore. There are only us,” said Vader coldly. Obi-Wan visibly gulped. “Do you truly want to remain loyal to those, who had abandoned you, thrown you away? Don’t be a fool. Join me and I will show you the way of the Force.”
“Damn it, Anakin.” He should have known that the formerly blonde Knight knew about Obi-Wan’s past. And once more, Qui-Gon wished that the small boy could hear and see him.
“I…” Obi-Wan hesitated. His light was being suffocated and replaced by the seeds of doubt, hate, confusion, anger and darkness. If Obi-Wan were to make that final step now, he would fall and his dark flame would burn as strong as his light had. He would still be a force to be reckoned with, but Qui-Gon did not want to think about all the things he would do to the galaxy.
“Join me, I will be your Master, your guide and teacher,” Vader continued, aware that he was about to reach his goal, “I will show you how to protect yourself and I would never abandon you, ever.”
Something in the blue-green eyes snapped and broke and it vanished into nothingness. The darkness roared in triumph and the brave light was snuffed out by the all consuming darkness, leaving behind a flame, as black as coal.
“No,” Qui-Gon breathed out and he fell to his knees. “No,” he shook his head. This was not how it was supposed to go. Obi-Wan had been supposed to train Luke and Luke had been supposed to bring Anakin back into the light. This was, what the Force had intended. So what had gone wrong in the end?
“I would be honored… Master,” and with the redhead’s last word, the pact was sealed. Blue-green eyes turned gold-red and the galaxy’s doom was born… the dark side had won.
