Game of Thrones, Season 4

(Cersei comes to join Margaery, who eyes her warily)

Margaery Tyrell:
(coolly) Your Grace?

Cersei Lannister:
(they both watch her son Tommen) There he is.

Margaery Tyrell:
Long may he reign.

Cersei Lannister:
'Long may he reign.'

Margaery Tyrell:
He sits the Throne like he was born to it.

Cersei Lannister:
Yes. He wasn't, though, was he?

Margaery Tyrell:
No, he wasn't.

Cersei Lannister:
You still mourn for Joffrey? (touches Margaery's black mantle)

Margaery Tyrell:
He was my husband, my King.

Cersei Lannister:
He would have been your nightmare.

Margaery Tyrell:
(pause) Your Grace, I-

Cersei Lannister:
You knew exactly what he was. I did, too. You never love anything in the world the way you love your first child. It 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. (Margaery glances at her, then they both look towards Tommen) He's only a boy. A good boy, a decent boy, he always has been. Who was the last decent king, I wonder?... He could be the first man to sit on that throne in fifty years to actually deserve it.

Margaery Tyrell:
(nods) It would be some consolation, wouldn't it? For all the horror that put him there.

Cersei Lannister:
He will need help... if he's going to rule well. (looks pointedly at Margaery)

Margaery Tyrell:
He has you. (ducks her head respectfully)

Cersei Lannister:
A mother is not enough. You're still interested in being Queen, I take it?

Margaery Tyrell:
(scoffs) After all that's happened? (Cersei continues looking at her pointedly) It sounds strange, I know, but I haven't given any thought to it. What comes next. (she meets Cersei's gaze) It would be a great honor, of course. But I will have to speak to my father about it. (she watches Mace Tyrell talking to someone in the hall)

Cersei Lannister:
Yes, speak to your father. I'll speak to mine. (watches Tywin, standing next to Tommen's throne.)

Margaery Tyrell:
(leans close to Cersei conspiratorially) We may be faced with an alarming number of weddings soon. (they both smile, amused) I won't even know what to call you. Sister, or Mother? (Cersei's smile fades as she looks away, remembering her betrothal to Loras)
