Er...you do realize that Elrond is still married to Celebrian, don't you? She sailed for the Undying Lands to receive mental healing, not to divorce her husband.
I'd actually be interested to read about how Celebrian reacts when she finds out that Elrond committed adultery with Mary Sue, but I doubt you'll write it.
I've read this a couple of times, and the only part I don't like is the reference to Celebrian; Arwen, Elladan, and Elrohir's mother. Tolkien explains in Fellowship that she was "torment[ed] in the dens of the orcs." I know it's a small detail, but it changes the mood a little. Other than that, I LOVE it.
