I have ambivalent feelings towards this character. He seems to have been a touchy topic in Rivendel. He abandoned his family a bit too readilly for my liking. I know he was saving the world and all that, but I think his sons got a bit of a raw deal...
Hey yeah, I remember when Strider said to Bilbo something like, "You're on your own if you want to make rhymes about Earendil in Elrond's house.." I think. That was my interpretation anyway...They don't talk about Earendil in Elrond's house?
I don't think that his sons got a raw deal though. Elrond and Elros were taken in by Maglor & Gil-galad, weren't they? So they had a home...what's there to complain about? Earendil did what he had to.
