Game of Thrones, Season 3

Catelyn Stark:
[Holding a knife to Jeyhousse's throat] Lord Walder! Lord Walder, enough! 'Let it end! Please... He is my son, my first son! Let him go and I swear we will forget this, I swear it by the old gods and the new, we will take no vengeance!

Walder Frey:
You already swore me one oath, right here in this castle. You swore by all the gods that your son would marry my daughter!

Catelyn Stark:
Take me for a hostage! But let Robb go. [Turning to Robb, who is holding Talisa's body on the ground] Robb get up, get up and walk out, please! Please!

Walder Frey:
And why would I let him do that?

Catelyn Stark:
[Turning back to Walder Frey] On my honor as a Tully, On my honor as a Stark! Let Robb go, or I will cut your wife's throat!

Walder Frey:
[Shrugs] I'll find another.

Robb Stark:
[Stands up weakly] Mother...

Roose Bolton:
[Walks up to Robb and holds him on the shoulder] The Lannisters send their regards.

[Roose stabs Robb through the heart with his longsword. Robb gasps for breath and falls back dead on the ground. Catelyn screams in anguish as she cuts Jeyhousse's throat. She drops the knife as her face goes blank, she is left standing there before Black Walder comes up behind her and slits her throat]
