“We were king’s men when we began,” the man told her, “but king’s men must have a king, and we have none. We were brothers too, but now our brotherhood is broken. I do not know who we are, if truth be told, nor where we might be going. I only know the road is dark. The fires have not shown me what lies at its end.” “Justice.” Thoros smiled wanly. “I remember justice. It had a pleasant taste. Justice was what we were about when Beric led us, or so we told ourselves. We were king’s men, knights, and heroes . . . but some knights are dark and full of terror, my lady. War makes monsters of us all.” “I am saying we are human. You are not the only one with wounds, Lady Brienne. Some of my brothers were good men when this began. Some were . . . less good, shall we say? Though there are those who say it does not matter how a man begins, but only how he ends. I suppose it is the same for women.” BwB is definitely in flux. Many of them are tired of war. A large portion of them don't like the way justice are carried out. Plenty of them are grateful for Brienne to save the children. All they need is someone who can lead them. Given that Gendry saved Brienne from her fight with Biter, he has grown to be more assertive. He will have a larger role to play given his story arc. Stoneheart is not going to be united with Arya as GRRM is not one to do so. Hence I think Gendry is the one who will emerge from Jaime/Brienne/unCat a leader who leads to the demise of unCat. Isn't that GRRM's favorite ironic thing to have Gendry undo unCat given his close relationship with Arya in the past. More tragic, less obvious.

I believe the resolution of UnCat/Jaime/Brienne situation lies with Gendry. He will revolt against UnCat and split the BwB with the likely result of the demise of Stoneheart and possibly Brienne. The original BwB has been disenchanted by the tactics of Stoneheart based on AFfC. They are looking for someone to lead them. Gendry will be someone they can rally around once Brienne/Jaime reveals to him and others about his parentage. Stoneheart herself has no magic or power. All she has is the title of being Ned's wife and Robb's mom. Once there is a legitimate challenger, her reign will be over.
