Glen is a recruiter for the Movementarians. He and Jane welcome Homer and other Springfielders to their free weekend retreat, then brainwash them into joining the cult. They were successful with everyone but Homer who required a special method to break him.
Glen has short grey hair. His clothes are simple and similar in style to those of the other recruiters': a light blue shirt with a dark blue tie and pants/a dress of a blue color lighter than the tie but darker than the shirt.
