Suffering is the fuel in the engine of civilization.Now he begins to understand: because pain is a god—he has been in the grip of this cruel god ever since Anakin’s death. But it is also a teacher, and a bridge. It can be a slave master, and break you—and it can be the power that makes you unbreakable. It is all these things, and more.At the same time.What it is depends on who you are.But who am I? he wonders. I’ve been running like Dad—like Anakin. I think they stopped, though; I think Dad was strong enough to turn back and face it, to use the pain to make himself stronger, like Mom and Uncle Luke. Anakin did, too, at the end. Am I that strong?There’s only one way to find out.
