I kept hoping that Sansa would eventually see what a good man Tyrion is, but Martin wasn't having any of that. Having the not-kneeling slight be the work of Joffrey instead of Sansa was an improvement, because that way it doesn't look like Sansa is being a bitch. And we get yet another reason to hate Joff.
Also, the crows aren't Coldhands' pets. Not sure how far you are in the books, but Coldhands serves someone else. The crows are that someone else's. Also, I wonder how much of Sam we're going to see for a while. Iirc, in the books, he kinda disappears for a while as soon as Coldhands shows up.
