Curufin was bored. Bored, and angry, and as always, annoyed. His was a heart and a fëa that burned even hotter when he had nothing to temper it. And here, he was feeling angry and rejected - and having his least-favorite brother here certainly wasn't helping. Curufin knew well why he disliked Maitimo so, although he was loathe to put it to words.
His eldest brother was the only one - of all the six brothers he had - who was strong-willed enough to stand in his way. Maglor was too flighty and distracted. Caranthir was nothing. Celegorm was weak, and easily corrupted, and the twins were irrelevant. But Maitimo was strong, and smart, and constantly put himself in Curufin's way.
And he hated that.
Still, he was his only brother here, and as such, he found himself making his way in the direction of his brother's apartment. He needed something to do, and a glass of wine with his brother was something. As annoying as he was, at least he wasn't one of these uppity mortals who saw themselves as far more than they were.
He reached the door and knocked firmly, getting annoyed as he had to wait for a few moments.
