Gandalf and Elrond come to terms with their own past mistakes while Aragorn reveals the lengths to which he’s gone to repair the faults of Isildur. As the story continues to unfold, the truth becomes clear to all at the Council of Elrond: Frodo’s ring is the One Ring cut from the hand of Sauron, and Gandalf isn’t afraid to use strong words — in the Black Speech — to prove it. We meet Radagast (in flashback), get word nerdy on a rather condescending name for Hobbits, and look for eucatastrophes in our favorite non-Tolkien stories.

I think Mandos is just telling it how it be: All elves are going to fade, whether they like it or not. It’s just that the ones in Aman are presumably getting a smoother gentler transition facilitated by the Valar; whereas the elves who cling to Middle Earth past their time will make things harder on themselves* until they must seek the Grey Havens, or in the case of particularly stubborn ones, until their fëa consumes their hröa and they have nowhere else to go but to Mandos’ hall, unless they wish to wander the earth as powerless disembodied wraiths for the remainder of time.
*like being stretched, perhaps, like butter that has been scraped over too much bread?
