I could spend posts and posts wondering why D&D rushed the last part of this epic story. I could go on and on about inconsistencies and plot holes and problems between the books and the shows. But one moment from last night's episode sort of caught all the absurdity in one microcosm:
You're telling me that The Hound and Arya depart from Winterfell on horseback. They travel south through a war-torn realm gripped in chaos, untouched. They arrive at King's Landing untouched, and manage to literally just walk inside, untouched. They manage to do this just as the city is closed, even though Dany and company came by boat and beat them by presumably many weeks to begin the siege. Then they walk straight into The Red Keep. Then they walk straight to the map room. Then, AFTER ALL THIS, the Hound tells Arya she probably shouldn't, and she's just like: "Okay I won't." Then, the Hound literally walks straight into Cersei and company. Even though they're clearly RIGHT THERE, Cersei somehow slips out without bumping into Arya on the way down.
I get it.. But I don't think they were anticipating the Red Keep to be in the process of being disintegrated as they walked in.
