Before one of the many formal events that the royal family participated in
I love older brother!Feanor. I mean, he really dislikes Indis but after enough time of cute siblings tagging along after him he would have to crack. And I think that he really loves children, considering that he had so many of his own!
Kid!Fingolfin totally is the kind of child to get dressed in nice clothes and then go outside and get completely muddy, so no one ever lets him wear pretty things and he's always excited when his big brother gives a sigh and goes to get a circlet for him.
Little Findis really likes pretty things too (I guess it just runs in the family) and loves balls because she can just stare at all the sparkling jewelry and beautiful dresses.
Feanor...well, I think we all know how much he likes shiny things.
