Jacen was curious as to how this would go. Teaching someone. Talking about his beliefs, what he was now. It did not escape him that the last student he had was Tahiri Veila and before her, his cousin Ben Skywalker. Neither of whom anyone would call a student. No, they had been apprentices, and now he was taking on Starkiller himself, Galen Marek. Of course Jacen knew of him, everyone that had grown up in the New Republic knew him. And it made sense in Jacen's mind to teach him what he knew. Galen would listen and maybe it would even help him. But the temptation to just let go, to be Caedus again. It was always there.
Was he even ready for this? Two lightsabers lay at his side. The red one he'd fashioned after killing Mara and the green one that had been his growing up. That he'd wished to have back. It was on that lightsaber that his hand rested as he finally reached the building he'd mentioned. And Galen was there. Meditating as he took apart and rebuilt his lightsaber.
"Did he teach you that?" he asked letting the Force project his voice. "My Grandfather. Or did you have Jedi training before he found you. I'm not entirely sure on the story there. Luke Skywalker taught me. A Jedi Acadamy on Yavin 4 and me and my twin sister were among a group there. We were taught how to be Jedi Knights, taught how to be strong and how to fight for the New Republic. The one you helped build. And that's commendable. It truly is." The peace didn't last of course, peace never did, and Jacen had fought and died to build a better world. He'd given up everything that he was because he thought that maybe that would do some good for the galaxy and for Tenel Ka and Allana. But it hadn't. Cade had shown him that. There would always be dark and always be light. It didn't matter if you were Jedi, Sith, Witch of Dathomir. No matter what it was, it was just the Force.
Being a Jedi certainly hadn't made Luke Skywalker a great man.
