Silas said, 'Out there, the man who killed your family is, I believe, still looking for you, still intends to kill you.'
Bod shrugged. 'So?' he said. 'It's only death. I mean, all of my best friends are dead.'
'Yes.' Silas hesitated. 'They are. And they are for the most part, done with the world. You are not. You're alive, Bod. That means you have infinite potential. You can do anything, make anything, dream anything. If you can change the world, the world will change. Potential. Once you're dead, it's gone. Over. You've made what you've made, dreamed your dream, written your name. You may be buried here, you may even walk. But that potential is finished.'
