Cersei Lannister (her fairy tale for Tommen): The little cub was frightened. His mother said, "You are a lion, my son. You mustn't be afraid. For one day all the beasts will bow to you. You will be king. All the stags will bow, all the wolves will bow. The bears in the north and the foxes of the south, all the birds in the sky and the beasts in the sea... they will all come to you, little lion... to rest a crown upon your head." And the cub said, "Will I be strong and fierce like my father?" "Yes," said his mother. "You will be strong and fierce just like your father."
Cersei Lannister: The Gods have no mercy. That's why they're Gods. My father told me that when he caught me praying. My mother just died, you see. I didn't really understand the concept of death, the finality of it. I thought that if I prayed very, very hard, the Gods would return my mother to me. I was four.
Sansa Stark: Your father doesn't believe in the Gods?
Cersei Lannister: He believes in them, he just doesn't like them very much.
Cersei Lannister (to Sansa): Permit me to share some womanly wisdom with you on this very special day. The more people you love, the weaker you are. You'll do things for them that you know you shouldn't do. You'll act the fool to make them happy, to keep them safe. Love no one but your children. On that front, a mother has no choice.
Tyrion Lannister: Listen to me, Queen Regent. You're losing the people. Do you hear me?
Cersei Lannister: The people. You think I care?
Tyrion Lannister: You might find it difficult to rule over millions who want you dead. Half the city will starve when winter comes. The other half will plot to overthrow you. And your gold-plated thugs just gave them their rallying cry... "The Queen slaughters babies." You don't even have the decency to deny it... It wasn't you who gave the order, was it? Joffrey didn't even tell you. Did he tell you? I imagine that would be even worse.
Petyr Baelish: When boys and girls live in the same home, awkward situations can arise. Sometimes, I've heard, even brothers and sisters develop certain affections. And when these affections become common knowledge, well... that is an awkward situation indeed, especially in a prominent family. But prominent families often forget a simple truth, I've found.
Cersei Lannister: And which truth is that?
Petyr Baelish: Knowledge is power.
Cersei Lannister: I felt something for you once, you know?
Robert Baratheon: I know.
Cersei Lannister: Even after we lost our first boy. For quite a while, actually. Was it ever possible for us? Was there ever a time, ever a moment?
Robert Baratheon: No. Does that make you feel better or worse?
Cersei Lannister: It doesn't make me feel anything.
Robert Baratheon: Sometimes I don't know what holds it together.
Cersei Lannister: Our marriage.
Robert Baratheon: Ah, so here we sit 17 years later, holding it all together. Don't you get tired?
Cersei Lannister: Every day.
Robert Baratheon: How long can hate hold a thing together?
Cersei Lannister: Well, 17 years is quite a long time.
