I understand it's quite a common tactic of confidence tricksters and con artists to throw a veil of confusion and/or complication over what they're doing so as not to be questioned. And then lay emotional manipulation over that. There's a technical term for it, I can't exactly recall it right now.
But it reminds me of prestidigitation or sleight of hand like conjurors use. You know, they distract the audience's attention by waving red cloths around and making big gestures, so the audience is too distracted to notice how they are doing the actual trick.
Those American celebrity pastors do the same kind of thing. You know, the super rich televangelists who con loads of money out of their adoring congregation for private jets and riches, all whilst claiming the money's being used to do the work of God. Even after they get exposed, their congregation refuse to hear a word against them. That's the power of emotional manipulation. In a parallel life, Jack could easily have been one of those pastors.
