Arguably one of the things that Daenerys would most want you to forget is that she's not really achieved anything. She's taken her enormous Unsullied army and walked into cities without breaking a sweat, but in the grand scheme of things, if she died in the next episode, the world would shift immediately back to the way it was. The Dothraki would continue pillaging, raping, murdering and enslaving at will. Astapor and Yunkai leaders would get their confidence back and the slave industry would boom. The Sons Of The Harpy would seize their city back, thousands would die, slavery would be reintroduced, and Daenerys' legacy would be a meagre one. She wants to make a dent, but she's only creating a scuff mark. Move to Westeros, yeah?
