Oh sure, we talk about some relatively obscure Silmarillion-based stuff in this episode, like the origin of the Light of Eärendil that Galadriel gives Frodo back in Lothlórien, and the legendary half-elven hero behind it. And of course, we check in with the Rohirrim as they make their way to Minas Tirith and talk about unsung hero of the book, Ghan Buri Ghan. But this ep is dominated by one thing: a giant damn spider. Shelob has arrived! So this is the Giant Spider Episode.
