On a semi-related noted, Davos & Gendry's conversation in the Dragonstone dungeon regarding "The Highborn" was pretty much dead on as well...
GRRM is pretty good at shattering expectations and changing our opinions of characters (sometimes he does over do it just to be shocking though). Another good example of this is Jamey's story about why he broke his oath and killed the King.
I thought that was awesome!! During that conversation, I got the feeling that Davos regrets becoming a knight and earning his name. He probably sees that as the moment led to his son's death.
