Celebrate the end of Pope Benedict XVI's short reign with a look back at the good the bad and the ugly of the polemical pontiff's career. We'll discuss all the big questions you probably don't care about: will Benedict still be 'infallible'? What were the real reasons for his resign? What will he do now? Who will be the next pope? Also, a brief history of Papal resignations before Benedict and we turn to Stephen Greenblatt's book "The Swerve" for a surprising connection between a former Pope and the rebirth humanism in the western world.
