Éomer, Third Marshal of the Riddermark, demands proper identification from the Three Hunters, and Aragorn gives it to him by name-dropping a lineage going back three thousand years and unsheathing a sword even older than that. In one of the greatest “okaayyy” moments in Tolkien’s legendarium, Éomer accepts their explanation and proceeds to catch them up on current events in this region where Saruman’s betrayal is more than just a rumor. Also, word-nerdery on another Old English word for a horse… hint: it’s not coconætt.
