I really like Maedhros' inner conflict here: not fully agreeing by how things are done, yet finding satisfaction of no longer bearing the responsibilty and yet it will never end for him. To me, with Celegorm gone his biggest 'oponent' is gone and Maedhros making amends for the deeds done by his brother servants shines a different light on his motive, especially since you portray him as someone who killed younger ones before. It leaves me to wonder what he would have done if he came across Elwing and the jewel as she tried to get away. I am going to stew on this for a while.

I think you provided excellent insights into Maedhros's, and indirectly Celegorm's, characters here.  I especially enjoyed Maedhros's inner conflict between pursuing the Oath and doing the decent thing and look for the twins.  Very rich and a good read.
