The thing is, if it had been half a year ago, Kili would have minded. As it is, he glances up when there's a sudden elvish presence and tips his head in a nod Maglor's way. The harp gets a curious look, brow quirked, and Kili plays the same song once more from the beginning, wondering if the strange elf can follow along.

Besides, how is he to know where or when Maglor comes from? Even if it is not common for elves to know dwarvish drinking songs. Still.

"You can play?" Because clearly someone would be carrying around a harp if they didn't know how. Good going Kili.
