Gold Meritorious Patron
Marty's losing his flock. He has nothing to offer them now that he's just passing on tidbits from old psychology texts. He's got no higher place to lead his followers. Many have already slid off the decks and slipped away.
He's also discarded his role as waystop on the way out of the cult.
... fade to black...
He was only a waystop as long as he was half in and half out. Getting fully out, as he seems to be, makes him less friendly to those who like the taste of just a little Kool Aid.
