I remember some other quotes, but do not have the books in front of me.
1) I thought Rasheed made some comment "it is not yet time for you to stand against the council...." that I thought was interesting.
2) Lash's comments in white knight, just before she sacrafices herself. Ofthen thought a reference to starborn or harry's powers vs outsiders.
3) I thought some of the words of Mother Winter and Summer were interesting in CD or summer knight.
4) and some of the comments of demonreach were cryptic and might be interesting.
