With Chris away on adventures both amorous and aeronautical, Rob and Thom navigate the maturity curve of world religions, the fractal nature of social groupings, the telltale portents of Christian pop songs, and, perhaps most importantly, whether a remake of Red Dawn is workable in 2012. Plus, unexpected visitors, backward backbeats, and what Thom really does while everyone else is talking. Music by Uncle Green, Big Fish Ensemble, and Paul Melancon.
