it will never cease to delight me that in the trilogy, gimli is shown to be charming, with all the polish and grace of a trained diplomat—he trades wits with elrond and speaks so graciously to galadriel that she gives him a gift denied feanor; his extemporaneous description of the glittering caves is what convinces legolas to travel there with him after the war, he sings the song of durin so well that sam begs to learn it.
whereas legolas is this big cheerful lug of a hunter-tracker, incidentally a prince, only unwittingly beautiful and graceful—his speech is decidedly stiff and formal, even when he’s trying to be gentle, but then turns around and starts singing without realizing he’s forgotten half the song. He has strange moments of seriousness, when the ancientness of him shines through, but then—
I do wonder what their first conversations were, gimli dignified but a little chilly; legolas stiff even as he attempted humor, but a way forward nonetheless.
