At first Kili doesn’t get what Hawkeye’s saying. After all, dwarves weren’t shy in any sense of the word; they had openly gone bathing as a company in Lord Elrond’s fountains, were family as much as anyone could be. Sure enough, he did love them, but he had no plans to marry any of them either, except perhaps Gloin’s beard (but only the beard). They had spent months, nearly years on the road with each other at times, not only on the journey but as mercenary escorts, training, diplomatic tag-a-longs. There was never any embarrassment over exposed skin after all that time.

Still, his expression brightens with a warm smile when he realizes that he has indeed earned himself a friend, even further when he catches on to the joke.

“She’d think you’d found a splendid dwarf with the promise of a majestic beard,” he goes right along with the joke with an eager spirit. “I hope you like mountains. And diplomatic things. ‘s very important to be diplomatic when on the arm of an heir.”

Oh yeah, spoiler he’s a prince. He doesn’t care much for the title, nor what it entails for himself or his brother down the road. What he does care about, though, is making his uncle and king proud, in preserving the line of Durin’s honor.
