As someone who has read all the books, it’s clear that
The TV people and their simple mindedness have taken over, which is too bad. Last week was the most disappointing episode of the entire show. Intricate plots, character development, good storytelling have all gone into the crapper in the interest of wrapping things up quickly.
With that caveat, I think that they’re clumsily building the storyline that Aria will end up killing Daenerys. Leaving Jon. And if not him, which he promises he does not want, Gendry has a claim since he is the only son of the last King. Also, wouldn’t be surprised if Aria is preggo. Not sureSansa has a legit claim. Besides, the iron throne is probably under 50 ft of rubble.
