A guy appears and replies with "valar dohaeris" and gives you a small coin. You admire the coin for a while and when you realize, the man disappeared. The Khaleesi stands up for herself against her brother Viserys after the would-be king of Westeros finally takes things too far. It's not long after this that Viserys finally gets the crown he deserves -- though not the one he wanted -- when Khal Drogo has molten gold poured onto his head.
With no hope, but with a coin in the pocket, the only logical path is here.
