Carl: Well, it's time for that war. But the shinies need a leader; a general, someone who was meant to bring them together. Someone like you.
Aiden: Why me?
Carl: I think it's what the book is trying to tell us. And the shinies are all children. Who better to lead them than you?
Aiden: Well, what if I'm scared? What if I'm not brave enough?
Carl: Even brave people get scared. Do you think your mom's not scared sometimes? She is. So am I. But what makes a person brave is not letting their fears stop them.
