A laugh was a better reaction than the on Din probably deserved considering the absurdity of his question, but he'd take it all the same. He supposed he simply hadn't given Jedi a great deal of thought, and those he'd come across thus far had been on their own, without even a clan to protect them. Though they didn't seem to need one either if all Jedi were as skilled as Ahsokah and Luke.
And then Luke went on, explaining about his own parents, the death of his mother and then his father and Din felt his breath catch. "Oh." He said softly at that revelation. Everyone knew about Darth Vader, at least it felt like it - his influence in the outer rim had been a fierce thing, but here was Luke - laughing and smiling, seemingly nothing at all like one of the leaders of the Empire. But maybe he'd seen some of that in the way Luke had so skillfully dispatched the dark troopers aboard Gideon's ship. He didn't know.
"My parents were killed on Aq Vetina." He said finally, because Luke had shared a part of himself, something that felt big despite the openness with which it had been said and that deserved something from him too. "The Mandalorians took me in that same day."
