The Catelyn chapters have more intrigue than the Tyrion ones at the moment. Robb comes back to Riverrun. There's some drama in the yard involving some Frey boys trampling Robb's banner and leaving in a huff. It turns out it's because Robb got injured, was nursed by a pretty girl, and ended up marrying her. The Freys are annoyed because he'd promised to marry one of Lord Frey's daughters. Oh dear, the message here seems to be that much of history is written by powerful men thinking with their dicks. It does seem awfully plausible.
This lets Catelyn off the hook a bit for releasing Jaime. But Robb's overall position does not seem that great. Catelyn seems to have a cunning plan to get the Freys back onside and I think it might involve "Tansy" aka her sister. Is that really going to cut it though? Isn't she a slightly mad cat lady living in isolation at the top of a mountain?
Also Robb is sending his wolf off to the kennels because some of his wifes people don't like it, and it doesn't like them. Catelyn thinks this is a bad sign, and I think she's right. GRRM is clearly telling us that the wolves were sent by the gods, and I'm fairly sure that this whole game of thrones business boils down to various gods vying for power.
Meanwhile Edmure is in deep shit. I remember being a bit suspicious back when Riverrun was celebrating its victory over Tywin. Turns out Robb's plan all along was to draw Tywin east and keep him distracted. Instead Edmure delayed him and he ended up preventing Stannis from taking King's Landing. Oops. Still, it wouldn't have hurt Robb to keep Edmure in the loop on his plans. "Just follow orders" is all well and good until events happen and you have to make decisions. Robb will learn from this, hopefully.
