Game of Thrones, Season 4

'Oberyn Martell:
It seems I visited the Lannister brothel by mistake.

Tyrion Lannister:
Oh, they take all kinds.

Oberyn Martell:
Even Dornishmen, it seems.

Tyrion Lannister:
The king is very grateful that you traveled all this way for his wedding.

Oberyn Martell:
Let us speak truth here; Joffrey is insulted. I am only the second son, after all.

Tyrion Lannister:
Well, speaking as a fellow second son, I have grown rather used to being the family insult. [Oberyn chuckles] Why did you come to King's Landing, Prince Oberyn?

Oberyn Martell:
I was invited to the royal wedding.

Tyrion Lannister:
I thought we were speaking truth.

Oberyn Martell:
The last time I was in the capital was many years ago. Another wedding. My sister Elia and Rhaegar Targaryen, the Last Dragon. My sister loved him. She bore his children. Swaddled them, rocked them, fed them at her own breast. Elia wouldn't let the wet nurse touch them. And beautiful, noble Rhaegar Targaryen left her for another woman. That started a war and the war ended right here when your father's army took the city...

Tyrion Lannister:
I wasn't actually present-

Oberyn Martell:
And butchered those children. My nephew and niece. Carved them up and wrapped them in Lannister cloaks. And my sister, you know what they did to her? [Tyrion doesn't answer; Oberyn lifts his chin with a finger until they are eye-to-eye] I'm asking you a question.

Tyrion Lannister:
I've heard rumors. [shoves Oberyn's hand away]

Oberyn Martell:
[chuckles coldly] So have I. The one I keep hearing is that Gregor Clegane the Mountain raped Elia and split her in half with his great sword.

Tyrion Lannister:
I wasn't there. I don't know what happened-

Oberyn Martell:
If the Mountain killed my sister, then your father gave the order. Tell your father I'm here. And tell him the Lannisters aren't the only ones who pay their debts.
