The people in the play are either overwhelmed or they are too busy to turn their heads

Margaery Tyrell: [pouts as she walks in on her brother on bed with his male lover] We're late for dinner as it is.

Loras Tyrell: You're very respectful.

Margaery Tyrell: I'm very hungry.

[closes door, casually eats fruit, then bothers to address the newcomer:]

Margaery Tyrell: What's your name?

Olyvar: Olyvar, my lady.

Margaery Tyrell: I'm afraid my brother is keeping the king waiting... Olyvar.

Olyvar: [kisses his paramour one last time, then acknowledges:] My lady.

Margaery Tyrell: [regards his naked body in a bemused way as he walks towards door, opens it and leaves, then looks at her brother:] Perhaps you might consider being a bit discreet?

Loras Tyrell: Why? They all know about me anyway. Everybody knows everything about everyone. What's the point of trying to keep a secret in a place like this?

Margaery Tyrell: In any event, you shouldn't keep your intended waiting.

Loras Tyrell: My intended? Please! Tywin's dead. That means no one can force Cercei to marry me.

Margaery Tyrell: Lucky you.

Loras Tyrell: Unlucky you.

Margaery Tyrell: You think I want that woman to marry my brother?

Loras Tyrell: If she doesn't marry me, she doesn't go to Highgarden. Which means she stays in King's Landing. Which means you're trapped here with Cercei Lannister as your mother by law.

Margaery Tyrell: Perhaps.

Loras Tyrell: Perhaps?

Margaery Tyrell: Perhaps.

Hizdahr zo Loraq: [after Queen Daenerys distances herself from being a politician] Forgive me. You're right, of course. Still... it's easier to rule happy subjects than angry ones.

Daenerys Targaryen: I don't expect the Wise Masters of Yunkai to be happy. Slavery made them rich. I ended slavery.

Hizdahr zo Loraq: They do not ask for the return of slavery. They ask for the reopening of the fighting pits.

Daenerys Targaryen: The fighting pits? Where slaves fought slaves to the death?

Hizdahr zo Loraq: In the new world that you've brought to us, free men would fight free men. The pit fighters you liberated plead for this opportunity. Bring some here and ask them yourself.

Daenerys Targaryen: [adamant] No fighting pits.

Hizdahr zo Loraq: Opening them would show the people of Yunkai and Meereen that you respect their traditions.

Daenerys Targaryen: I do not respect the tradition of human cockfighting.

Hizdahr zo Loraq: If you could...

Daenerys Targaryen: [angrily] How many times must I say no before you understand?
