And all the other aspects of winter. For instance, I didn't see anybody's breath in the air when people were talking outside Winterfell during "The Battle of the Bastards." Distinctly odd for a time and place that's supposed to be dealing with the most savage winter in thousands of years.

Not really news, but HBO just started their Game of Thrones Marathon with Season One Episode One. I recommend a prime spot on the couch, a plate of leftovers and that ugly - but really warm - new blanket you got yesterday. And lots of hot tea. And cookies.
So I guess either Arya makes it to the end of the series, since she's read the end and usually you only get the scripts for your episodes, or this is one of those fake endings HBO has been talking about scripting and shooting.
