Theon mopes around Winterfell. He's back to being Reek. None of the Northmen like him because of his cloak turning. He can't save Jeyne. She's in her room crying all the time. Theon has to arrange for her daily baths.
There are still references to Manderley's pork pie eating. Mmmm, pork. Are those Freys still missing?
Abel sings slightly modified versions of songs. One of his women questions Theon about how he captured Winterfell, but Theon is paranoid and does a runner. Is she trying to make friends with him for the benefit of whatever scheme Abel is really up to?
Another of Abel's women is walking around barefoot in the snow. Who could put up with that amount of cold? A wildling, perhaps?
Things don't look great for Stannis. Winterfell's walls and moat are pretty impregnable, and there is a storm coming. His horses can't go fast in the snow. Neither side is likely to have much food, though. I'm starting to think the Dornish could win the throne just by being the only ones with any food left. Or will the snow get to them, too?
Lady Dustin goes down to the crypt, mainly to make long expositionary speeches at Theon. The crying fake Arya is not winning the loyalty of the northmen. The Freys hold the Greatjon captive (did we know that? I suppose he was at the red wedding). There are swords missing from the crypt. I think Bran and company must have taken some. Lady Dustin was wanting to marry Brandon Stark (Ned's brother) but Ned's dad Rickard arranged (with advice from his Maester, presumably) a marriage with Catelyn instead (but not before Lady Dustin gave her maidenhead to Brandon). But Brandon was killed in battle, Catelyn married Ned (who Lady Dustin would have settled for) and she was left with Lord Dustin, who then died in battle for Ned. Now she wants to intercept Ned's bones, presumably on their way from Deepwood Motte, so she can feed them to his dogs.
I'm not really sure of the significance of this sub-plot, to be honest. I fully expect an Aha! moment any chapter now.
