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.
