Cersei visits the new Great Septon who takes his faith annoyingly seriously. Baelor's sept is surrounded by sparrows: displaced faithful who are here complaining that the king is not protecting them from followers of Stannis's god. She agrees to overturn an ancient law against faithful taking up arms. The Great Septon is so keen on this idea that he forgives the crown all the debts. Cersei is very pleased with her cunning. Which means it is all going to turn out to be a huge disaster. Probably the newly armed faithful are going to either cause havoc throughout the kingdom or else just gain a lot of power and influence over the king by being able to physically threaten him. Or just replace him.
Until then, Cersei is more interested in plotting against Maergery, who is probably being incestuous with Loras, as if Cersei has a leg to stand on in that regard. I don't see her coming out on top there, either. I'm getting ready to almost feel sorry for her. And Jaime won't even be around to protect her from whatever comes next...
