Ever since her conversation with Ghost, Daenerys was in deep thought-she wanted to take Cersei down. She wanted the Kingslayer dead too. Definitely Joffrey, although she didn’t know about his sister, Myrcella. She knew that the girl was sweet and didn’t deserve to be the pawn in a game of thrones.
She wanted to find warriors, Dracarae. Ghost was of Stark, and she Targaryen. They could burn Cersei’s life to the earth.
She had been hearing rumors that Drekistone, the pack that Joffrey had claimed, was somewhat of an ancestral home. Not just for anyone; for Dracarae. And now a group of lions was living there?? For this, she all the more wanted to burn Cersei. The Lannister twins should fall to her wrath.
She knew of a powerful Dracarae in Tarben. Disgusting pack, just like Amaya; she needed to get out of there.
In the forest, she found a red, limp shape that she immediately recognized to be Lady Sansa. “Sansa?? Sansa?” she called to the girl. “Lady Sansa Stark.” Then she wobbled, and fell.

“Fire cannot kill a dragon.”
