[Mandalore93]

Say it with me people, it was not Theon's plan to take the north. The reason he was sent to Pyke in the first place is twofold. Firstly, he's Balon's son. Secondly he's the one who came up with the alliance plan for the Islanders to attack the Westerlands.

Secondly, at the time of Roose taking command, he's done nothing treasonous that anyone's heard of. Even his eccentricities aren't known given his "quiet rule" policies. He's a seasoned commander and known for being level headed and a man who thinks. He is the logical choice at the time in comparison with the other idiotic lords. Even after he pretty much defies what Robb thinks he would do...he can't be relieved. He's one of the most powerful bannermen that Robb has. This isn't a centralized state where you can just pull generals left and right.
