Despite being what some people would call a "book purist" (that is, I think Benioff and Weiss' invented material has been consistently cliche-ridden and poorly thought out; if they made a substantive rather than logistical change that was actually any good I'd be fine with it), I find it difficult to care about any of this week's changes, because I know they're not going to come to anything. The show is just marking time so it can hold the ending of A Storm of Swords
to the final episodes of the season. As with the changes to Dany in season 2, everyone will end up exactly where they do in the books. In narrative terms, anyway; I'm sure the whitewashing of certain fan favorites will continue. But that's nothing new either.
