Game of Thrones, Season 6

Walder Frey:
You've lost it?!

Walder Rivers:
Yes father.

Walder Frey:
It's a castle, not a bloody sheep. Presumably you still know where it is? You didn't lose Riverrun: you let the Blackfish take it from you!

Lothar Frey:
He surprised us. He knows the castle better than anyone.

Walder Frey:
You did lose the Blackfish after the Red Wedding. You had him right here in this hall and you let him leave. And when I told you to hunt him down and kill him, you couldn't find him! That's what it means to lose something! Now he's come back and taken Riverrun!

Walder Rivers:
I don't think it's fair to blame us.

Walder Frey:
For three hundred years, we kissed Tully boots, swore oaths to them and their stinking fish banners! Not again! Riverrun is ours! Take it back!

Lothar Frey:
We don't have the men!

Walder Frey:
We've got ten times as many men as the damned Blackfish!

Walder Rivers:
The Mallisters have risen against us, and the Blackwoods!

Lothar Frey:
The Brotherhood Without Banners is rallying the commoners against us, raiding our supply trains and camps!

Walder Rivers:
Riverrun can withstand a siege for a year! [Furious, Walder Frey strikes his new child-bride]

Walder Frey:
If I want excuses, I'll put her in charge! They're laughing at us! All across the Riverlands, right down to King's Landing, they're laughing at us! I hear it in my sleep! I'm not dead yet -unfortunately for you! - and I'll not leave this world until they all choke on that laughter! Take that castle back!

Lothar Frey:
He'll never yield, Father.

Walder Frey:
Oh, he'll yield. You'll show him the knife you used to kill Robb Stark's child in its whore mother's belly and you'll show him the knife you used to open his niece's throat. And you'll remind him who it was that got married at the Red Wedding in the first place! His nephew. [The guards bring in a chained Edmure Tully] Cheer up, Lord Edmure. You're going home.
