Quiet as it was Jacen could sense his uncle almost as soon as he walked in and nodded just once to indicate Luke should join him at the table. He too had brought no weapons. It was a gesture, as much as the one Jacen had made but it meant a great deal that they were both willing to take that chance. Although they could both still fight of course. If they had to. Jacen noted too that his uncle looked older. It must have been from after they'd called him to them, him and Ben. It was another of the memories that kept him from becoming Caedus.
Ben had forgiven him. Luke too. And he'd been having a nice damnation before the seal saw fit to make him part of the war here.
"Luke" he said simply, willing to wait until the man got a drink of his own. "Is it still hot chocolate? I can order you one if you'd like." All very polite but Jacen still found himself unable to call Luke Skywalker either Uncle or Grandmaster, so Luke would have to suffice. And he figured talking was the best way to go about this. Being open, being honest. Talking it all out. It wouldn't be easy. He supposed for either of them. But if they didn't do this, it would get messy.
Of course he had no idea where Luke would start, there was so much between them and perhaps always would be. But he sensed hope, and in the former Sith Lord, the Jedi would sense an acceptance of the mistakes of his past. It wasn't guilt, not quite. More a quiet regret that things had gone the way they had.
