Margaery Tyrell: Cersei is not here. Tommen is not here. Why do you think they're not here?
High Sparrow: If the accused is not here, she will be tried regardless. We cannot escape the justice of the gods...
Margaery Tyrell: Forget about the bloody gods and listen to what I'm telling you. Cersei understands the consequences of her absence and she is absent anyway, which means she does not intend to suffer those consequences. The trial can wait. We all need to leave. We all need to leave now!
Tommen Baratheon: You're a good person. You've always been a good person. You're the best person I know. I was just telling him about your devotion to the poor.
Margaery Tyrell: Ah, yes, I visited their hovels and I fed them soup and I made sure I was seen doing it. I never gave them what they really needed, though. I've had lots of time to think about how good I was at seeming good.
Cersei Lannister (about Joffrey): You never love anything in the world the way you love your first child. Doesn't matter what they do. And what he did, it shocked me. Do you think I'm easily shocked?
Margaery Tyrell: No.
Cersei Lannister: The things he did shocked me.
Olenna Tyrell: Luckily for you, the Queen Regent is rather distracted at the moment. Mourning her dear departed boy. Accusing her brother of his murder, which he didn't commit.
Margaery Tyrell: Well, he could have done.
Olenna Tyrell: He could have done, but he didn't.
Margaery Tyrell: You don't know, Grandmother.
Olenna Tyrell: But I do know. You don't think I'd let you marry that beast, do you?
