He's like the mirror image of Walder Frey but with more finesse and cunning.
He dislikes that he is of humble birth and that he has always been looked down upon by noble houses. He dislikes that he loved Cat and he was deemed an inappropriate suitor due to being low class. The fact that he was looked down upon due to being of humble birth did nothing but to fuel his desire to move up in the world. After his duel with Brandon Stark and Cat marrying into the Starks - not only were the Tully's on his list, but the Starks as well. He can't stand the fact that they both looked down upon him, so now he wants to be the one looking down on them, he wants to be their downfall and cause their demise. He's doing wonderfully thus far. What better way to pay them back than to seduce Sansa and end up Lord of the Vale, and WF and (if he is able to do it) end up on the IT. The Starks, Tully's, and Arryn's would roll over in their graves and he would have the ultimate revenge and his goal would have been achieved - to gain as much power as possible while bringing down those who looked down upon him.
So nobody has said anything about this yet, but at the end of GRRM's quote he is talking about redemption, and did Olenna need redemption that poisoning Joff would have brought essentially. What I gather from that is GRRM is telling us that the poisoner is one who is seeking redemption of some sort. Not revenge, not betterment for the realm, but redemption. Is there anyone present at the wedding who is on a redemption arc? In the show I know Jamie is (and he doesn't seem too terribly sad that Joff dies) but in the books I don't remember if Jamie is back yet.
Are there any other characters that could fall into the redemption category that are in the wedding party?
1) ToJ is still listed as an in tact structure on the maps. The key has symbols for a ruin and the ToJ is not depicted as a "ruin" that is claimed to be.
2) How the heck would Ned and Howland manage to pull down a tower in the first place, by themselves? I mean, think about how impressed Ygritte was with Queensgate and that was just a ramshackle tower, I imagine ToJ must have been nice and not nearly as dilapidated - meaning those stones would have been difficult (and heavy) to break apart from the mortar that was holding them together.
3) Are we serious in thinking that nobody went to recover the bodies of the three dead KG? Nobody wanted back Arthur Dayne, the Sword of the Morning's body for their family crypt??????? We'll take his sword back, but we're going to leave his body out in the middle of no where...?????
Maybe Ned was the one person in Westeros to deduce that "rape" coupled with an extended length "kidnapping" might have a good chance of resulting in pregnancy?
I would also say that even had she not told him, even if he had not deduced the info, that there was probably a good chance something or some one else clued him in. Maybe he found something in the love nest, maybe a servant told him, maybe KG told him at some point...
I think LF was definately involved in getting Brandon killed but I don't think he did it himself. I think it was more of a comment or two passed to the right persons ears who then ran to the Starks with the info. LF was the master mind but essentially led other people in the direction he wanted them to go while sitting back to see the fruits of his labor.
Yes, that was one of my concerns, I was not sure if we knew how long he had been blind. I wonder if he trusted anyone else with that tidbit of information so that they could write it down for him? Mormont perhaps? That seems like a stretch though, best to keep that sort of information to oneself, especially if Jon was not on the wall at that time and the Targs were on the decent.
I would find it a strange sort of irony if JonCon and Rhaegar did have some type of relationship and JonCon raised fAegon to honor Rhaegar only to find out he's a fake and that Rhaegar's real son is at the wall.
