He'd been on Earth almost half a year now and still many of it's customs were alien. Like knocking. But maybe that was also mostly a Jedi thing. Many of them could sense eachother before the knock even happened, so it was fairly pointless. Still Elena had taught him that it was important. Especially if one was to interrupt something awkward or potentially embarrassing. Tahiri had also taught him this.
Raising an eye brow as Mara hugged him, he hesitated for a moment and hugged her back. Really the only people who he'd hugged in the past few months had been Elena. He was attached to her, an part of him felt guilty for it. Most of his family insisted that it was not cheating on Tahiri, but he still was unsure.
"Hello Aunt Mara." He greeted her in return after a few moments of just soaking in the warmth of her touch and becoming accustomed to her in the Force. It had taken him some time to adjust to her being alive after all the horrible things Jacen had told him. "Is everything all right?" He could feel some of her anxiety, blue eyes that matched Luke's met hers curiously.
