After that brief break for Professor Freeman, that is. Everything is so much clearer now! Bela's a servant of Sauron!
I bet Borges really liked the whole Moria episode, if he ever read it. Actually, he and Tolkien were contemporaries (they were born seven years apart, with Walter in the middle, as it happens), so Tolkien might also have been reading and liking Borges, though somehow that's not quite as easy to imagine. Maybe because I think of Borges as devouring fantasy writing in every language, and I don't know what kind of stuff Tolkien liked to read. Weird Argentinians? Maybe!
The little servant of Sauron is hovering in his bud vase at the moment. Scheming, probably.
