Game of Thrones, Season 1

Eddard Stark:
I know the truth Jon Arryn died for.

Cersei Lannister:
Do you, Lord Stark? Is that why you call me here, to pose me riddles?

Eddard Stark:
[gesturing to the bruise on Cersei's cheek] Has he done this before?

Cersei Lannister:
Jaime would have killed him. My brother is worth a thousand of your friend.

Eddard Stark:
Your brother? Or your lover?

Cersei Lannister:
The Targaryens wed brothers and sisters for three hundred years to keep bloodlines pure. Jaime and I are more than brother and sister; we shared a womb, came into this world together - we belong together.

Eddard Stark:
My son saw you with him.

Cersei Lannister:
Do you love your children?

Eddard Stark:
With all my heart.

Cersei Lannister:
No more than I love mine.

Eddard Stark:
And they're all Jaime's.

Cersei Lannister:
[chuckles] Thank the gods. In the rare event Robert leaves his whores long enough to stumble drunken into my bed, I finish him off in other ways. In the morning, he doesn't remember.

Eddard Stark:
You've always hated him!

Cersei Lannister:
Hated him?! I worshipped him! Every girl in the Seven Kingdoms dreamed of him, but he was mine by oath. And when I finally saw him on our wedding day in the Sept of Baelor, lean and fierce and black-bearded, it was the happiest moment of my life. And that night, he crawled on top of me, stinking of wine, and did what he did - what little he could do … and whispered in my ear, "Lyanna". Your sister was a corpse, I was a living girl, and he loved her more than me!

Eddard Stark:
When the king returns from his hunt, I will tell him the truth. You must be gone by then, you and your children; I won't have their blood on my hands. Go as far away as you can with as many men as you can, because wherever you go, Robert's wrath will follow you.

Cersei Lannister:
And what of my wrath, Lord Stark? You should have taken the realm for yourself. Jaime told me about the day King's Landing fell. He was sitting on the Iron Throne, and you made him give it up. All you needed to do was climb the steps yourself … such a sad mistake.

Eddard Stark:
I've made many mistakes in my life, but that wasn't one of them.

Cersei Lannister:
Oh, but it was. When you play the game of thrones, you win or you die; there is no middle ground.
