Welcome! No, I don't remember them... what is their significance?
Ston, I'll try to be more ridiculous in the future.
Aegon, Eyrie. Imo, Brynden is cut from the same cloth that Ned, Robb, Jaime, Mace and all the other warriors of the realm, unlike Petyr. Pros for Brynden's regency of the Vale: He's not ambitious, he's loyal, he'll do his duty without personal gain. Cons: He's not of the Vale, the Vale lords know he's a nobleman but so are they and they think they can do the job just as good as Brynden.
Brynden as Regent will be just like Ned as Hand. Ser Rodrik's words when Catelyn took Tyrion hostage show how these honorable warriors think. Rodrik said something like, "I'll thank you all to not say anything about what you've seen here." He expected the people there to see the moral high ground of the Starks and to respect that. Ned expected Petyr, Cersei, Pycelle, and Renly to always seek to do the right thing even if costs them.
Petyr knows how to reward people. He motivates them with tangible ways to improve their socio-political standings. If Brynden tries to deal with Petyr using the same methods that Ned used, I think the result will be the same. I think Ser Lyn would rather take the chance to kill Brynden for Littlefinger's rewards than serve Brynden for nothing.
What awaits the Blackfish in the Vale? At best a cold shoulder, at worst death.
Brynden must go to the heart of Stark power to raise them back up. That means the North.
He'll make a call for fealty. He'll call upon the love the northern lords have for the Starks. He'll say how just they were compared to the Boltons, the Lannisters, the Greyjoys, and all the rest. He'll say how only the Starks can hold together a united North to resist southern dominance.
Robb rose up against his rightful king. He declared independence. He did this for what reason? Glory? Revenge? Freedom?
Roose Bolton rose up against his rightful king. He took over his king's lands. He made himself the new lord of the north. Why? Honor? Glory? Power? It was just there for the taking? It's in his nature to be a backstabber?
How is Roose different from Robb? Robb's father was unjustly killed by the Lannisters. So Robb seceded. Robb lost the Freys and dishonored all his lords by breaking his sacred vow. Roose put an end to the war and regained his honor by taking the north from Robb. Note that Roose had the blessing of the rightful king for his undertaking... he was merely re-establishing royal authority in rebellious lands.
Now as for Sansa... she saw into Littlefinger's machinations regarding Lord Nestor Royce and Ser Lyn Corbray. She's coming along. But taking apart an engine and building your own from scratch are two different things. She'll soon be taking a more active role in Littlefinger's ploys and con games, but it'll be a while before she's ready to devolp and hatch her own plots in the grander politcal game.
