King George and Snow in “Unfinished Business”

You're going to sneak in and tell him you received his letter. You're going to tell him why you're here, because you don't love him. It'll break his heart, and that'll cure him.

Snow

Or you'll kill me.

Oh, no. I'll kill him. Killing you would just make him love you more, and the marriage and the kingdom would ultimately crumble. But if he were to die at an assassin's hand, he would die a martyr. Midas will forgive, even laud, the death, and the merger would be complete.

Snow

You would do that to your own son?

He is not my son.
