Daenerys approached the Weirwood Tree with Jon, she hadn't left his side since arriving at Winterfell. There Jon saw his brother Bran. Daenerys studied the boy who knew all things while she stood there quietly as Jon and Bran discussed the Night King and how Uncle Benjen had saved them both while they were North of the Wall. Bran sat there rather stoically which made Daenerys uneasy because she couldn't quite read him. They never spoke the entire time during Jon and Bran's conversation and it was only when Jon and Daenerys started to head back that he glanced at her, "Brave men didn't kill dragons. The brave men rode them. Rode them from Valyria to build the greatest civilization this world has ever seen." she was taken aback by his words then she turned to him, as he continued. "The Night King, he brought back the dragon of gold and cream. But he is no longer your dragon."
Daenerys' eyes widened at this and Jon stopped in his tracks, "What?"
Bran looked at them both, "Viserion." with that Bran warged somewhere else.
"I have to tell the others," Jon said heading back toward the castle. "We have to move now there's no telling how long we have."
But Daenerys stood in front of Bran now "What does he mean he is no longer mine?" she touched Bran's arm. "Tell me!" she said defiantly.
Bran's eyes locked onto Daenerys' now; "You dare? You give commands to me? To me? You do not command the dragon."
Terror overtook Daenerys as she let go of Bran's arm, haunted by the words, knowing that they were the words spoken to her once by her brother Viserys.
