Which RotE character is your favourite? (spoilers all RotE books)

[Chrischa]

Some very interesting points! There certainly is a similarity between Fitz' actions and Chivalry. I hadn't even considered that angle yet, I was more thinking about how his name might tie him to never be more then a "son". As in; never seeking to be more then his father is, in this particular case never having ambitions for the throne. Son-Of-Chivalry might also bind him to never be Chivalry himself, if you know what I mean.
And yes, I know that Fitz was ready to take up stewardship when Regal fled inland during the Red Ship War, but he didn't do that as a result of years of ambitions and careful planning, but only because he knew no-one was more suitable and more likely to hand power back to Kettricken and her child.

As to the other aspect you brought up; I can think of three points in his life when Fitz was so much like Chivalry that other people even commented on it. First of all of course there's his physical appearance and the way he is built, moves and fights. Secondly he wants to marry for love rather then political advantages (Shrewd actually calls him Chivalry during this argument, doesn't he?). And thirdly he abandons his task just when the kingdom needs him the most; he doesn't want to be an assassin any more.
