Jon is having wolf dreams again. Has he really not figured out that he really is inhabiting his wolf's body? I think he probably knows it but doesn't want to think about it too much. Via telepathy, we know that of the four remaining wolves (Sansa's was killed by Ned) one of them can no longer be sensed. Whether because dead (we think Robb's wolf was killed at the Red Wedding) or not is ambiguous. Bran's wolf Summer smells of summer, weirdly.
There's a bit of a Wildling refugee problem, but at least there are some spare lands for them to settle. Melisandre still wants two kings' blood, a father and a son to wake a dragon. Okay, confirmation that Jon does know what is going on with the wolf dreams: he thinks his wolf knows that Robb's wolf is dead. He also thinks that Bran's and Rickon's wolves have escaped, but not Bran and Rickon.
Stannis's and Melisandre's men are staying at Castle Black. One of them, Ser Godry Farring challenges Jon to a sparring session. But Jon has to go and see Stannis to tell him why he won't be giving him half the Night's Watch's abandoned forts. Stannis is trying to get various northern lords to declare for him and not having much luck. He's only the Karstarks who don't have much choice since Lord Karstark got beheaded for killing one of Robb's prisoners. Stannis thinks he can marry Val to some lord and the Wildlings will follow him, but Jon explains that it's a stupid idea.
He's also trying to explain that Dalla's boy is not a prince so there's no point burning him to death for some spell. There's a discussion about Gilly and Dalla's son. It's clear Jon is already planning a baby switcheroo.
Jon seems to be expecting another Wildling attack from Tormund and asks Melisandre for intel. She warns Jon she thinks he'll be murdered by daggers in the dark surrounded by ice. It's not the most useful prediction and it's a bit of a worry.
