Of course, there has been a ludicrous amount of analysis and thought devoted to Danaerys' sudden turn from self-righteous crusader to genocidal maniac, and much of it is far better than what I could offer. Honestly, though, it wasn't Dany's actions after the bell rang that infuriated me. I'd been watching with clenched fists and narrowed eyes since Drogon dove out of the sky and destroyed the entire Iron Fleet with dragonbreath inexplicably upgraded to deal massive concussive force. The sudden power-up would have been bad on its own, but combined with the entire structure of the season thus far... well, let me explain.
In both the books and the HBO show, the first thing we ever see is an attack by mysterious creatures from the far North, beyond the Wall. Throughout the entire story, while wars are waged and kings are made and then murdered, Jon Snow had been at the Wall, reminding us over and over that all of that Southron drama only mattered insofar as determining how much help the Night's Watch would have in protecting the Seven Kingdoms from the dead. The White Walkers were the looming threat, advancing ominously closer, and Westeros was not prepared to even recognize the threat, let alone resist it.
