Game of Thrones, Season 3

Sansa Stark:
Is that wise, my Lord?

Tyrion Lannister:
Tyrion, Sansa. My name is Tyrion. [pours himself a cup of wine]

Sansa Stark:
Is that wise, Tyrion?

Tyrion Lannister:
Nothing was ever wiser. Astoundingly long...

Sansa Stark:
What?

Tyrion Lannister:
Neck. You have one. How old are you, exactly?

Sansa Stark:
Fourteen.

Tyrion Lannister:
Well, talk won't make you any older. My lord father has commanded me to consummate this marriage.

[Sansa pours herself a cup of wine and hastily drinks it; she begins undressing]

Tyrion Lannister:
[shakes his head] Stop. I can't... I could, but I won't.

Sansa Stark:
But, your father...

Tyrion Lannister:
If my father wants someone to get fucked, I know where he can start. I won't share your bed. Not until you want me to.

Sansa Stark:
What if I never want you to?

Tyrion Lannister:
"And so my Watch begins."
