Here's something maybe someone can explain for me ...
The High Sparrow is the dumbest guy on the planet, right? Having not read the books, but pretty much reading all the book spoilers, all I've heard for years is that where the books end, Cersi awaits trial and Frankenstein/Mountain is going to fight for her in trial by combat. But now that Cersi is inside the Red Keep, what possible reason could there be for her to participate (or even leave the Keep)? The religious nuts will kill Margaery and Loras ... so what? The only reason Cersi gave power to them in the first place was to get Margaery out of the picture. We've been told 200x that the only people Cersi cares about are her kids; two of them are dead and the other one is catatonic in his bedroom.
Why wouldn't she immediately order the City Guard (or Lannister army) to absolutely annihilate the Sparrows as quickly as possible? Why have book readers believed she'd even consider participating in a trial? The only reason I can come up with is that Tommen won't come out of bedroom until his wife has been released ... so Cersi can't wipe out the Sparrows (out of fear they will kill Margaery immediately) - but as far as I can tell, that's pure speculation and has no basis in actual books.
Someone explain this to me ... wtf is the High Sparrow thinking?
