In a scene that never made it to screens, Jon was seen travelling through the ruins of King’s Landing before meeting up with his aunt and lover Daenerys.
The scene’s caption in the book reads: “As Jon heads into the Red Keep, struggling with a choice only he can make, he comes upon a huge pile of snow that reveals itself as a sleeping Drogon.
“Recognising Jon Snow, Drogon allows him to pass through the door that leads to the throne room… Unsullied soldiers guard below.”
Moreover, the scene would give more explanation to Drogon’s reaction to the death.
