Sansa Stark is the oldest daughter and second child of Catelyn and Ned Stark. She is betrothed to Joffrey Baratheon by Robert and Ned.
Joffrey: I'll tell you what. I'm going to give you a present. After I raise my armies, and kill your traitor brother, I'll give you his head as well.
Sansa: Or maybe he'll give me yours.
Sansa: Where do you come from, the north or the south?
Septa: I come from a very small village...
Sansa: Oh wait, I just realized I don't care.
