S6E10, the last episode of the sixth season, gave an explanation for the slow and slow episodes before (although I liked the Hound and Arya a lot, but still felt that it took up too much space), and opened up a new situation for the next season by the way.
Because the Pope High Sparrow forced Tommen to abolish the trial by combat in the last episode and cut off Cersei's way of using the magic mountain to fight, I was desperate for her, worried that Cersei would be replaced by Little Rose as the witch predicted. Yesterday's star. Because Queen can refer to Xiao Rose and Long Ma, it is the general trend to be replaced by Long Ma, and it is very possible to be marginalized by the new queen before. Therefore, if you have a hole card (Magic Mountain), you can't reveal it in advance, and you should come by surprise. It's not just the church's lax security for this matter, because it was explained before that there are secret passages under King's Landing, and little birds can come to them at will. The reason why a little bird appeared on the steps was not because the wildfire had just been set up, nor was it to trap Lancel, it was just to let the audience know, to surprise everyone, and to get angry.
It is said that Cersei has reached the level where she must pay her revenge, and even this pedantic nun will not be spared. Not only to destroy her body, but also to torture her spirit. Alas, the Demon Mountain was the villain who raped and killed Princess Rhaegar and Princess Dorne back then. The Red Viper didn't kill him, and he should have died at the hands of the Hound in the end.
