re: Crackpot ASOIAF Theories SPOILERS

You know, I'm having some issues with some arcs in the novels, particularly the Stark Children's and Cersei's. With Cersei, it's pretty easy to assume that at least a month has gone by since her last chapter, and with all the Stark children, I'd assume that 6 months had passed between each of their chapters. A fan calculated that they're only into July since the Purple Wedding, which means Tywin has only been dead for half a year. Surely it's been at least a year since Tywin's death. I particularly don't buy Arya speaking fluent Braavosi, even if she's completely immersed in it. It's said to take at least 10,000 hours of study to be even proficient at a language, and even if we don't count sleep, Arya isn't even close to that. Unless she's a true language protégée (and there's nothing to indicate that Arya is) it's incredibly impractical that in 6 months or less that she'd be able to fool a Braavosi to believing she is one of them.
