Question: a man is no one game of thrones?
Answer: At Braavos, after being dropped off at the House of Black and White, Arya Stark calls to the door of the ancient building. An old man answers her call and she asks for Jaqen H'ghar, only to be told that there is no one by that name inside. Some time later, Arya is saved by the same Faceless Man and follows him.
