"I understand they're your children, David," Rhiannon said, very slowly. "But you didn't raise them. I was there every day of their lives. Do you know what Addy's favourite stuffed animal was? What Iestyn's favourite lullaby was? Do you know their favourite foods? I know them. I know them so well, I can tell their frustrated cries from their heartbroken cries from their pain cries. I want you to build a relationship with them. Of course I do. But they are about to go through something so monumentally huge, and- I'm not saying this to hurt you- They need someone who knows them. And that isn't you."
