“It's not always so simple, Haven. Sometimes there isn't a good guy and a bad guy. Sometimes even the ones you want to believe turn out to be liars.”

Context: Here it was again, the most ancient of roadforks, one that Paul had glimpsed before, in Kroner's study, months ago. The choice of one course or the other had nothing to do with machines, hierarchies, economics, love, age. It was a purely internal matter. Every child older than six knew the fork, and knew what the good guys did here, and what the bad guys did here. The fork was a familiar one in folk tales the world over, and the good guys and the bad guys, whether in chaps, breechclouts, serapes, leopardskins, or banker's gray pinstripes, all separated here.
Bad guys turned informer. Good guys didn't — no matter when, no matter what.
