"In theory, cars are fairly simple. If they don't start, it's either the fuel system or the electrical system. Teach yourself about the path of each in your engine and tracing it is fairly straightforward. But at the beginning, mastering each new system seems like an unreachable shore. The car is effectively a black box."

Normally Connor would walk away from a conversation like this. His life is about tangibles: things you can see, hear and touch. God, souls, and all that has always been like a secret in a black box he couldn't see into, so it was easier just to leave it alone. Only now, he's inside the black box.
