In the final pages of “Fog on the Barrow-downs”, the hobbits — now armed with nice, shiny daggers — reluctantly take their leave of Tom Bombadil. Before we say goodbye to Tom, we give the greatest enigma in Middle-earth the full Prancing Pony Podcast treatment! We answer listener questions, respond to popular theories, and assemble a council’s worth of comments from our favorite scholars (including an unpublished letter by Tolkien himself) before making our final conclusions about what Tom Bombadil really is. A day may come when your hosts have an epic disagreement… is it this day?
