"Living with the wildlings beyond the wall, Jon Snow now sits on the Frozen Council - a newly formed group of elected Freefolk that governs over the various factions throughout the wild North. Along with Tormund Giantsbane and three other Wildlings, they oversee the care and defense of their people. Jon helps design their new settlements, as well as training and leading the hunting and ranging parties.
Although he was assigned (again) to the Nights Watch, he has never returned to the Wall since his reunion there with Ghost and the Freefolk. Jon's farewell with his Stark family left a bitter taste in his mouth, and his desire to follow Bran's order and rot alone at the wall for the rest of his life was about as strong as Bran's attempt to save him from this fate in the first place.
Jon suffered from nightmares every night since the day he stuck his dagger into Dany's heart and watched as Drogon destroyed the Iron Throne before carrying her body out across the sea. Her face haunts him every night he lies down and closes his eyes to sleep, until he wakes up and opens them again the next morning. Staring at the fire always leads him to her, Daenerys. It always shows him a future they will never have, making him want to avoid it, and struggle to look away at the same time. A vision of them beneath a weirwood tree, a field of flowers blooming around them, pledging himself to her, now and always. Another vision of her lying on his chest, his hand on her pregnant belly, feeling her play with his hair as they talk about names for their baby and joking about how long until they can take the baby for dragon rides. Hearing Dany's words and remembering their times together echoing in Jon's head every day as tried to find meaning in his life now that she was gone, and his family and yet again left him to die alone out beyond the wall. Struggling with everything he has given up for them just to be left out alone in the snow, while hearing Dany's pleas to be together over and over in his mind, has left him easily angered, insomniatic, and deeply depressed. The only one who seemed to be his truly constant companion in life was his beloved and loyal direwolf, Ghost."
