Just watched the episode to see what the fuss is about. Why did Rob's missus get shanked in the belly? - No one knew she was preggers and in fact she wasn't even at the wedding in the book :S she stayed away, and up untill the current book we haven't heard from her (so she could be back and g. r. martin could **** the whole story up by bringing her back in the next book).
Over all it was a good episode, but you miss a lot of the internal dialoge. Especially when Catyln dies (thank god cos she was an annoying character in the book - but her 'thoughts' as she died added to the overall sequence - rather than having her stand there like a muppet mouth open untill someone slit her throat.
I recommend reading the books and then watching the corresponding eposiodes a short time later so you pick up on all the small sublte things the actors do sublte expressions, looks, reactions, locations ect.
Good way to spend travel time up north too
