Ah 🙂
Yes, as you’ve gathered, Thror and Thrain didn’t figure it out. But Frerin definitely did. Even though it hurt him (and Frerin doesn’t deal very well with his own pain, only with other people’s) he watched the whole sorry story unfold. Thror and Thrain had to leave when Thorin fell under the gold’s spell (too much, too painful, too close, my son, my grandson, not you, not you, not again, no no no – ) but Frerin stayed. Frerin saw. Young, clever, immature Frerin knew long before Thorin did. He knows his brother, after all.Â
Fris is an inconstant watcher. She is more likely to care for people one-on-one, where she can speak to them and care for them. She is very good at comforting those she loves, and watching people suffer at a distance is not something she can handle very well. She knew Thorin cared for Bilbo, but not to the extent that he did.
Vili visits Dis every morning without fail. Not in one hundred and forty years has he missed a sunrise. He now and then stopped in on his boys as well, and he noticed a thing or two that puzzled him – particularly after the Carrock. But there were so many more pressing things for him to consider, really. His boys’ safety and survival (and later, Kili’s immediate attachment to this strange Elven captain) occupied most of his thoughts.
Hrera spotted it immediately. She knows what it is to dislike a person on sight, and through time and circumstances come to love the very things that had once seemed so obnoxious and ridiculous. She knew the minute Thorin swung down from a ledge upon the Misty Mountains to rescue his ‘useless burglar’. After all, how many times did she rail against her allotted husband, only to choose him for herself in the end?
