Chapter 3 - Jon
Jon is dreaming that he is Ghost. As Ghost he knows where the other direwolves of the pack that are still alive are. He can sense Nymeria and ShaggyDog. He knows Summer is still alive but can't sense him. When Jon wakes up, we see his side of the story about why he sends Aemon and Mance's son away with Sam.
Stannis wants something from Jon. Melisandre has been questioning the wildlings. Jon has a tricky decision to make. As he crosses the courtyard of Castle Black, he is accosted by one of Stannis' knights who wants to challenge him. The knight calls him a coward when he declines. Stannis has sent ravens to the Northern Lords but only Karstark has declared for him. Stannis wants all the castles along the wall so that he settle them on his lords and followers. Jon won't give them up so he threatens him.
Jon returns to his chambers and Melisandre accompanies him. She seems to generate her own heat. Melisandre tells Jon she can help him, tells him to beware the enemies that pretend to be friends. She closes with Ygritte's words, "You know nothing, Jon Snow."
I was surprised to see Sam still at the Wall but, of course, ADWD runs in parallel with AFOC (sort of) and Sam hasn't left yet. Silly me. And Stannis, once you start threatening people, you've lost the argument.
Jon really is Eddard's son (even if not biologically). He has the bent to do the right thing and an appreciation that it will often be very hard to work out what that might be. He wants to be just but he doesn't want to be harsh like Stannis. And he's not afraid to speak truth to power. So how will he keep and hold what he's got when everyone wants to take it away from him?
I think Jon's experiences of ruling the Wall are in parallel with Dany, Tyrion and Cersei. He seems to be handling things well, like Dany.
