Those changes were just stupid pointless changes. They served no purpose but to piss off book readers. Why bother changing it at all? I'm not giving up on the show or anything, it's still a great show, but I'm hoping the people making this show get an earful after this season., and realize they shouldn't change small things for no reason.
This episode pissed me off with a lot of the changes. They changed so many small things for seemingly no reason. Why not have Arya kill a guard? Why not have Robb and Catelyn find out about Bran and Rickon's "deaths"? Why not even mention the f'ing chain Tyrion has built? Ugh.
Did you know Book 3 is so good, that people have cried reading it? people have also thrown it against the wall in anger, it is actually better than book 1 and book 2. I've yet to read the 2nd book but i've heard many many things about how good book 3 is, next year s3 will probably put game of thrones in the top tv shows ever..
