Why would you want it, then?” Davos asked him.
“It is not a question of wanting. The throne is mine, as Robert’s heir. That is law. After me, it must pass to my daughter, unless Selyse should finally give me a son.” He ran three fingers lightly down the table, over the layers of smooth hard varnish, dark with age.
“I am king. Wants do not enter into it. I have a duty to my daughter. To the realm. Even to Robert. He loved me but little, I know, yet he was my brother. The Lannister woman gave him horns and made a motley fool of him. She may have murdered him as well, as she murdered Jon Arryn and Ned Stark. For such crimes there must be justice. Starting with Cersei and her abominations. But only starting. I mean to scour that court clean. As Robert should have done, after the Trident.
