Yup. The Rohirrim see this Elf standing there bitching at this maybe-Gondorian, maybe the King of the West, maybe just another weird Ranger, and the two of them are obviously arguing in a foreign language like the Rohirrim don't matter (which is how Men see Elves - stuck-up and isolationist, ignorant of the plight of Men), and then the Ranger says something that cuts straight to their own philosophy.
