When Jon approached the throne room, there was no one anywhere near the holdfast. Just Drogon, who has now flown away from the show forever. He walks to the edge of the room and looks down below, at the walkway to the keep. He says. We are at peak Jon Snow now. When enough people make false promises, words stop meaning anything. Then there are no more answers, only better and better lies. God, it kills him.
He was repeating his oath to her as he killed her. But he had no choice. He had no choice. As badly as he ever felt about anything, this is worse. He stumbles out of the throne room, and down the path of the Red Keep, past where he saw Drogon, and further downhill.
The first people he comes across are a group of Unsullied guarding a small house. The top has been burned off, but the bottom, cellar portion remains intact. The Unsullied look at each other, confused. Jon removes Longclaw. The sheath on his hip designed for a dagger, is noticeably empty.
Grey Worm arrives first, still not sure why he was summoned. He stands outside the basement where Jon has impriosoned himself, a cold feeling coming over his body. Instead he jogs to the throne room, by himself. We see him now, there in the throne room, looking down at the blood stain on the stone floor.
Snow has fallen to partially obscure it, but it was a puddle deep enough to turn most of the snow that fell upon it to a paste of pink slush.
