Luke Skywalker, the jedi master who just recently took in his first student, was sitting on the cold stony floor, waiting for his new charge to answer his calling. In front of him, two things were laying. One a small, silvery lightsaber hilt, once belonging to his former master, the being of the same species as the child who was curently under his care. The other, a small package containing a memento of the found family the child left behind when he went with him to learning the ways of the Force. Two symbols of two pathways laying before the young, Force sensitive child.
Watching the two items sprawled in front of him, Luke made a decision. He will give Grogu the choice. To eighter fully commit himself to his jedi training with all consequences, or return to his mandalorian adoptive father. I would be a difficult choice for many, and many could say it's harsh and even cruel to give the child such an ultimatum like this. But for Luke, it was not about the choice itself. It never was. Deep in his soul, he already knew what his charge's decision will be. Grogu himself might not fully realize it now, but he already made clear what he would chose if it had come to it. Every day of their training together, Luke could feel the child's inner struggling, he could feel that despite his eagerness to learn how to control these powers he was born with, he was always distracted, struggling with his training. His strength in the Force was remarkable, but he lacked the focus and with each passing day, it was clear that Grogu's heart and soul were elsewhere.
When Luke decided to become a jedi, he knew almost nothing about the order and it's many rules. He learned more with time, and he found out that not everything was as brifght and perfect as the young and naive, dreaming child might think. There were things he didn't exactly agree with. Things he wanted to make diferently. But he more and more realized, that even if he wouldn't forced his first student to renounce his family ties, even if he would not forbid him from seeing the Mandalorian who became his father, it would never be enough. His training, his duties if he would become the fully fledged jedi, would still occupy much od his time, and the Bounty Hunter's life was also very busy. They would barely have the time to be together. His charge was aging diferently, much slowly compared to humans, Luke could guess from what he knew about master Yoda who was the same species as him. For him, it would be like the few fleeting moments before his father would be gone forever. And the thought of that happening to him, to them both, brought the sense of sadness which went much deeper than just the compassion for the fate of the one orphaned child, spending most of his life separated from his chosen family. It reopened the wound he still carried in himself, which despite years passing by, despite of him being supposed to let it go, never truly went away. And he didn't want another child to lose what he himself lost just after he got it back. He didn't want another child to experience that loneliness and longing of being separated from his father... like he himself was. He knew, better tan anyone, that even if the pain can somehow numb and dull with time, it will never fully go away.
Sometimes, even now, after all these years, he was still haunted by dreams about Anakin's last moments, even though he never voiced it out loud. Sometimes, he could still see the shadows of the past comming back to him, much like when he went to rescue the child he was waitng for here right now, when walking and cutting and crushing through these pitch black mechanical creatures of dark armor and crimson red eyes, which made him unwillingly recalling his own darkest moments, the duel which almost cost him his own soul. It will be with him forever.
He knew that it was the will of the Force what made him hear the desperate call for help, and he knew that he did right when he took care of the child frightened by powers he could not control to learn him to accept and control them. But he also knew that this, Grogu staying here, was not meant to last. The child belonged with his father. He didn't know if this feeling was coming from the Force or from his own longing, still grieving soul, but he knew what he had to do now. He had to make his charge realize where his true home is. Where he truly belongs to. To help him overcome this struggling betwen the sense of duty which would only bring him loneliness, and his longing for his family.
Yes, he will give Grogu the choice, but he already knew what the child will chose. And he was more then ready so sent him back where he truly belonged. With his father...
