3. Syrio Forel
The Quote: "What do we say to the god of death?" Despite his short time on the show, Syrio Forel made a name for himself as one of the most badass characters around. The First Sword of Braavos, Syrio served as Arya Stark's "dancing master" in King's Landing. Apart from the sword training, Syrio also imparted some important lessons onto the young Stark girl. Most important of all, when facing certain death you simply say, "Not today". When things went sour between the Starks and Lannisters, it was Syrio who stood between Arya and several armed Lannister men. He stood tall against the overwhelming numbers and seemed unconcerned that they all carried steel swords while his was wooden. When Arya begged him to run, he simply reminded her what you say in the face of death. Then he was never seen again. Always the teacher, Syrio's last words echo the greatest lesson he taught Arya; survive. Throughout the show, Arya has encountered many of the world's most dangerous characters and yet, unlike many, she's still alive. Syrio's farewell wasn't an overly confident view of his own predicament, but rather some encouraging words his student would need when he's no longer there to protect her.
