Game of Thrones, Season 3

[Daenerys has just sold one of her dragons, Drogon, for an army of 8000 Unsullied]

Daenerys Targaryen:
Is it done then? They belong to me?

Missandei:
[after translating] It is done. You hold the whip.

Master Kraznys:
[attempting to rein Drogon in] The bitch has her army.

[Daenerys turns to face the Unsullied. Kraznys does not notice what happens next, as he is too busy with Drogon]

Daenerys Targaryen:
[In Valyrian] Unsullied! Forward march! [they do so] Halt! [They stop]

Master Kraznys:
Tell the bitch her beast won't come.

Daenerys Targaryen:
[turns to face him, still in Valyrian] A dragon is not a slave.

Master Kraznys:
[astonished] You speak Valyrian!?

Daenerys Targaryen:
[coldly] I am Daenerys Stormborn of House Targaryen, of the blood of Old Valyria. Valyrian is my mother tongue. [turns to the Unsullied] Unsullied! Slay the masters, slay the soldiers, slay every man who holds a whip, but harm no child. Strike the chains of every slave you see!

[the Unsullied begin slaughtering the Astapori slavers]

Master Kraznys:
I am your master. Kill her! Kill her!

Daenerys Targaryen:
[with a cold smile] Dracarys.

[Drogon breathes fire, burning Krasnyz]
