Sansa simply stopped, unsure if she was actually awake and not dreaming still. She had no idea what to make of this...fancy tale. On one hand, this was the most ridiculous thing she had heard in her life. On the other, the wildling woman looked deadly serious and had no real reason to lie to her. Walking through the fire unburnt? Only Daenerys Targaryen was said to have done such a feat, and Jon had nothing to do with Aerys" daughter. True, nobody knew who his mother was, but the only female Targaryen alive during the Rebellion was queen Rhaella and Eddard Stark had never met her. And flying lizards? Those sounded suspiciously like dragons, and they had been dead for at least a hundred years, if one ignored the whispers of Daenerys Targaryen in Slaver's Bay. But those were tales at best, and she had long learned not to trust hearsay. On the other hand, if this was true, it meant that her brother was alive.
