Syrio Florel: "Do you pray to the gods?"
Arya Stark: "The old and the new."
Syrio Florel: "There is only one god and his name is Death, and there is only one thing we say to Death: 'Not today'."

Arya: "I can't sleep until I say the names."
The Hound: "The names of every person in Westeros?"
Arya: "Only the ones I'm going to kill."

Arya Stark: "I'm not listening!"
Gendry: "But just explain it to me. He offered to have any three people you wanted dead. All you had to do was give him the names. Anyone. You could have picked King Joffrey."
Arya Stark: "Shut up!"
Gendry: "You could have picked Tywin Lannister."
Arya Stark: "Jaqen got us out of Harrenhal. So why are you complaining?"
Gendry: "Because you could have ended the war!"

Arya Stark: "Could you bring back a man without his head? Not 6 times, just once."
Thoros of Myr: "I don't think that's how it works, child."
Beric Dondarrion: "He was a good man, Ned Stark. He's at rest now. I would never wish my life upon him."
Arya Stark: "I would. You're alive."

Gendry: "They're a family. I've never had a family."
Arya Stark: "I can be your family!"
Gendry: "You wouldn't be my family. You'd be m'lady."

"Anyone can be killed."

Arya Stark: "How did you know we'd be here?"
Jaqen H'ghar: "After all the things you have seen, this is your question?"

Jon Snow: "Stick 'em with the pointy end."
Arya Stark: "I know which end to use."
