Stannis might lose.Also, the scene with Jon Snow writing the Boltons for help was idiotic. I mean, he JUST had a conversation with Stannis about how he was days away from marching south to conquer Winterfell, so why bother dealing with the Boltons at all right now? Yes, the Night's Watch needs men, but just wait for Stannis to conquer the place and then ask for help. It just seemed like an unnecessary scene considering the circumstances.
That said, they could just have easily replaced it with Lord Frey.
I think she is seeing this as the same thing she did to Ned Stark. A family who are soon to be enemies, acted against boldly before the actual conflict begins. A small force with a heavy street presence but little political power. Their leader and cause empowered in exchange for their support at a crucial moment.That's the thing, I think she views the high sparrow as naive and easily manipulated. And right now she has Margaery quite perturbed and seems rather pleased with herself.
Problem is, the Goldcloaks already had a stake in protecting the crown and law. Janos Slynt was greedy, venal and prideful which meant that his new position and accolades were important to him. The Goldcloaks were a semi-militarised with a command structure and organisation which meant they all obeyed orders.
The sparrows have no stake in anything, they are fanatic cultists. The High Sparrow is principled, intelligent and disdains the trappings of power. The Sparrows act on faith, not on commands, and will not necessarily obey the High Sparrow if he calls for restraint.
Oh, and Ned Stark wasn't feeding King's Landing this winter.
