[the Hound wakes up to find that Arya has disappeared. He finds her by a river, practicing her "water dancing"]
Sandor 'The Hound' Clegane: The hell you doing?
Arya Stark: Practicing.
Sandor 'The Hound' Clegane: What, ways to die?
Arya Stark: No one's gonna kill me.
Sandor 'The Hound' Clegane: They will if you dance around like that. That's no way to fight.
Arya Stark: It's not fighting, it's water dancing.
Sandor 'The Hound' Clegane: [laughs] "Dancing"? Maybe you ought to put on a dress. Who taught you that shite?
Arya Stark: The greatest swordsman who ever lived: Syrio Forel, the First Sword to the Sealord of Braavos.
Sandor 'The Hound' Clegane: [scoffs] Braavos. Greasy-haired little bastard, was he? They all are.
Arya Stark: [angrily] What do you know about anything?
Sandor 'The Hound' Clegane: I bet his hair's greasier than Joffrey's cunt.
Arya Stark: It was not!
Sandor 'The Hound' Clegane: "Was"? He dead?
Arya Stark: Yes!
Sandor 'The Hound' Clegane: How?
Arya Stark: He was killed!
Sandor 'The Hound' Clegane: Who by?
Arya Stark: Meryn Trant! That's why Ser Meryn's on my...
Sandor 'The Hound' Clegane: [incredulously] Meryn Trant? The greatest swordsman who ever lived, killed by Meryn fucking Trant?
Arya Stark: He was outnumbered!
Sandor 'The Hound' Clegane: Any boy whore with a sword could beat three Meryn Trants.
Arya Stark: Syrio didn't HAVE a sword! OR armor, just a stick!
Sandor 'The Hound' Clegane: [sarcastically] The greatest swordsman who ever lived didn't have a sword?
[the Hound laughs]
Sandor 'The Hound' Clegane: All right, you have a sword. Let's see what he taught you. Go on, do it for your Braavosi friend. Dead like all the rest of your friends.
[Arya lunges at the Hound's chest with her sword, but it lodges in his armor. He backhands her across the face, knocking her to the ground, then picks up her sword and points it at her throat]
Sandor 'The Hound' Clegane: Your friend's dead, and Meryn Trant's not, 'cause Trant had armor. And a big fucking sword.
[the Hound raises Arya's sword, looks at it for a moment, then hands it back to her]
