" You apologise to me?” she bellowed. “You apologise to me now? You say that you’re sorry when I have spent my life destroying you? You are my whipping girl! I hurt you because it was a relief! I exist because my parents killed everyone and relegated you to a life of abject misery, and they would have killed you too and not given it a second’s goddamned thought! I have spent your life trying to make you regret that you weren’t dead, all because—I regretted I wasn’t! I ate you alive, and you have the temerity to tell me that you’re sorry?”

“I have tried to dismantle you, Gideon Nav! The Ninth House poisoned you, we trod you underfoot—I took you to this killing field as my slave—you refuse to die, and you pity me! Strike me down. You’ve won. I’ve lived my whole wretched life at your mercy, yours alone, and God knows I deserve to die at your hand. You are my only friend. I am undone without you. "
