When, Miller wondered, does someone stop being human? There had to be a moment, some decision that you made and before it, you were one person, and after it, someone else …Emotionally, it had all been obvious at the time. It was only when he considered it from outside that it seemed dangerous. If he’d seen it in someone else — Muss, Havelock, Sematimba — he wouldn’t have taken more than a minute to realize they’d gone off the rails. Since it was him, he had taken longer to notice. But Holden was right. Somewhere along the line, he’d lost himself.
