Tywin Lannister: What do they say of Robb Stark in the north?
Arya Stark: They call him the Young Wolf.
Tywin Lannister: And?
Arya Stark: They say he rides into battle on the back of a giant direwolf. They say he can turn into a wolf himself when he wants. They say he can't be killed.
Tywin Lannister: And do you believe them?
Arya Stark: No, my lord. Anyone can be killed.
