Bran gets mail. Robb has won a battle against Stafford Lannister. We already knew that, but Bran feels a bit meh about it because he has never heard of Stafford. I can relate to that: it's a feeling I often get reading ASoIaF. Anyway, the Walders Frey's uncle is dead. They're pretty ok about that, and Bran is still worried. Which *perfectly* matches what Jojen predicted in his dream about not liking his delicious supper and the Freys enjoying their scraps!
So now Bran believes everything Jojen says. Except he says that Bran is going to to be murdered soon and have his face cut off, so that's not great. Also there is a prediction about Winterfell being flooded by the sea, which everyone inexplicably takes literally despite being told the dreams are cryptic. Probably it means Stannis or the Greyjoys (the ones with ships) are going to attack.
Poor Lady Hornwood (who everyone was trying to marry for her lands) married Roose Bolton's bastard and ended up dead shortly after. Now there is some infighting amongst the northerners over the Hornwood land and there's not much anyone can do because the King in the North is busy fighting Lannisters. Why can't everyone just get along?
