"You're Arya Stark. I swore to your mother I'd bring you home to her." After leaving the Bloody Gates, Arya and the Hound came across Brienne of Tarth and Podrick who were on their way to the Bloody Gates. Brienne asked for directions to the Bloody Gates when Podrick recognized the Hound. She then realized that the girl who's with the Hound is Arya Stark, one of the daughters of Catelyn Stark who she swore that she'll find and keep safe. Arya questioned Brienne's intentions when she knew that her mother was already dead. The Hound also didn't want to give Arya up that easily, thus a fight ensues between Brienne and the Hound.
