Capricious Crone

I wonder if the answer is the difference in Jon and Arya's personalities. Jon thinks often of the individual members of his family including Bran and Rickon. Arya thinks more about pack as a whole and revenge. When she thought about Robb it was because she wanted his strength. When she thinks about Jon it is with longing. I think she thought about Sansa a few times but I don't remember her specifically thinking about Bran and Rickon as individuals after she left King's Landing. Jon is a caretaker/protector, Arya is a wild she wolf. And of course Sansa lost her connection between wolves when Lady was executed. What do you think?

Arya has had plenty of wolf dreams, if Nymeria knows then so too should Arya and yet she doesn't seem to know but Jon does? It's fishy and confusing.

That's what I assumed but it would be telling if either Sansa or Arya know what Bran named his wolf but I haven't found anything that suggests they know.

Bran looked up calmly. “His name is Summer,” he said. ~AGOT, Chapter 17, Bran III On the other side the wind was colder still, the wolf sensed. That was where his brother was, the grey brother who smelled of summer. ~Jon's wolf dream, ADWD, Chapter 3, Jon I At Queenscrown, one had come out of the darkness to save Jon’s life. Summer, it had to be. His fur was grey, and Shaggydog is black. He wondered if some part of his dead brothers lived on inside their wolves. ~Jon's thoughts, ADWD, Chapter 3, Jon I Question: How did Jon Snow know that Bran named his direwolf Summer? Jon left Winterfell before Bran named his direwolf. We can speculate that the letter Jon received announcing Bran woke from his coma mentioned that Bran finally named his wolf but we have no proof as we never saw the contents of the message. We can speculate that Jon learned Summer's name through his wolf dreams, but again we have no proof. Does anyone have any other insights, conclusions or comments? Do you know of any other instances in the text where those who left Winterfell before Bran named his direwolf use the name Summer?
