Game of Thrones, Season 3

Robb Stark:
It took five of you to murder two unarmed squires?

Rickard Karstark:
Not murder, Your Grace. Vengeance.

Robb Stark:
Vengeance? Those boys didn't kill your sons. I saw Harrion die on the battlefield and Torrhen-

Rickard Karstark:
Was strangled by the Kingslayer. They were his kin.

Robb Stark:
[furious] THEY WERE BOYS! Look at them.

Rickard Karstark:
Tell your mother to look at them. She killed them as much as I.

Robb Stark:
My mother had nothing to do with this. This was your treason.

Rickard Karstark:
It's treason to free your enemies. In war, you kill your enemies. Did your father not teach you that, boy?

[Brynden Tully punches Karstark in the face]

Robb Stark:
Leave him.

Rickard Karstark:
Aye. Leave me to the king. He wants to give me a scolding before he sets me free. That's how he deals with treason. Our King in the North. Or should I call him the King Who Lost the North?

Robb Stark:
Escort Lord Karstark to the dungeon. Hang the rest.

Karstark soldier:
Mercy, sire! I didn't kill anyone. I only watched for the guards.

Robb Stark:
This one was only the watcher. Hang him last so he can watch the others die.
