“Jon wondered where Ghost was now. Had he gone to Castle Black, or was he running with some wolfpack in the woods ? He had no sense of the direwolf, not even in his dreams. It made him feel as if part of himself had been cut off. Even with Ygritte sleeping beside him, he felt alone. He did not want to die alone.” - Jon, A Storm Of Swords
“She threw back the coverlets. I must be brave. Her torments would soon be ended, one way or the other. If Lady was here, I would not be afraid. Lady was dead, though; Robb, Bran, Rickon, Arya, her father, her mother, even Septa Mordane. All of them are dead but me. She was alone in the world now. Her lord husband was not beside her, but she was used to that.” - Sansa, A Storm Of Swords
