Whoops, I got a bit behind in reading. Even though I read every chapter of this story, I love to see what you changed and expanded upon. The brotherly interaction between Maglor and Celegorm is played out wonderfully. Maglor still doesn't tell what exactly happened, but Fëanor knows something is amiss because previously his son was more than apt to answer his questions before Fingon would. You can sense the struggle of Celegorm here, fitting for his age: be honest and been seen as a loser in the eyes of the intruder, or stick to what has been said so far. Maglor understands him more than Celegorm realises and the embrace they had, this part particulary moves me deeply:
"Shh." He strokes my hair. "That will be our secret, Tyelkormo, and it shall go with us until the ending of Arda." His voice is gentle, forgiving, and it makes me cry harder. He kisses my ear and whispers, "Do not cry, little one, or you shall give it away."
We both know this will never come out. A beautiful chapter Dawn!
