I am finally caught up on this story. I actually had to go back and reread a few chapters, which was lovely, since his struggles to find his place in the shadow of his father lead up nicely through these latest chapters. In one, he has to deal with the bitter legacy of Arathorn's marriage to Gilraen in the form of Daeron, and the difficult quetsion of justice; he is still trying to prove to the skeptics among the Dunedain that he is a worthy successor to his father as both Heir of Isildur and Chieftain. The troll hunt is a way of trying to be a son to his father and avenge his death, and now at last he must face his father's grave in the company of brothers old and new. These chapters have been marvelous at showing an Aragorn attempting to negotiate the intricate ties of blood and loyalty and to create a family large enough to accommodate his own bonds of affection.
At the same time, of course, doing that is a political exercise, as noted, and Aragorn is steadily chipping away at resentment and skepticism.
The action in the troll chapter was well done, and satisfyingly horrific. I liked the light touches of morbid humor (kissing troll hags and turning them into Elves, which becomes a nice running gag), and also the lesson in how to hunt trolls. Very well thought out - it added to the sense of being present to begin an endeavor that may well cost some of the participants their lives. I knew the second Goenor said he likes to take along some lads who are light enough to scramble up those trees, that nothing good could come of this. One just gets that sinking feeling in one's stomach. And boy was it dead on target! The surviving twin's reaction to Elladan and Elrohir was poignant and appropriate, I thought, and it is good to think the Infamous Twins feel a certain responsibility towards a twin bereft of his brother.
