I can’t even start to express how beautiful that story is, and how wholesome. I love that despite all the grief that’s going on there, there is still no bitterness. It’s really a wonderful story, I especially like how the boys are just that, children, but still they represent a different bitter-sweet memory for everyone. They are not only Elwing’s brothers that she gets back, but they also give her the role of a mother back that she missed out on. Not as a substitude, of course, but just filling that aweful void that is childloss a little bit. Then Míriel with her clothes… it’s like she’s apologising for what her grandsons did, in a very beautiful, blame-less way. And for Olwë (I admit that was the point I started crying) seeing the twins must be, well no, IS like having a bit of his own brothers back. It’s beautiful. 

A wonderful fix-it.

(Not that it can fix absolutely everything, of course. It is more effective and believable that way.)

Oh wow. I’m glad they made that journey, but… I don’t think I’d ever have the strength to sail away again. What Elwind and Eärendil and Elros did there was so brave and so, so beautiful. 
 

And on a more easy-going note: I laughed a lot at Idril’s comment on Finrod wearing a whole dragon-hoard, and also at Elros dropping his crown. Whoops. LOL 

So Elurín sails the skies with his brother-in-law. I like that. It feels like belongs there, somehow, though he himself is still not certain, is he, if he really made the right choice? As is (was?) Eluréd?
I loved how you wrote Nimloth and Dior's return, because it was both beautiful and somehow awkward, as it surly must have been.

That's so beautiful, with Elrond returning at last. But oh boy, those first few days (weeks? years?) in Valinor must be stressful for Elrond, because as you say, he's related to half of them.
