Eddard Stark

— You will dishonor yourself forever if you do this.
— Honor?! I've got seven kingdoms to rule! One king, seven kingdoms. Do you think honor keeps them in line? Do you think it's honor that's keeping the peace? It's fear — fear and blood.

The king takes what he wants. That's why he's King.

— Ten is too young to see such things.
— He won't be a boy forever. And winter is coming.

— I swear if I weren't your king, you'd have hit me already.
— The worst thing about your coronation — I'll never get to hit you again.

— You're just a soldier, aren't you? You take your orders and you carry on. I suppose it makes sense. Your older brother was trained to lead and you were trained to follow.
— I was also trained to kill my enemies, Your Grace.
