Season 4 finale unaired cliffhanger scene, where Madison comes back. This was shot just in case wb/cw decides to renew the show. Originally, the producers had scripted a montage for the "series-finale cut" that went forty years into the future to show a majority of the gang at Andy's funeral — showing the series coming full circle; this was never filmed due to budgetary reasons as well as the producers' hopes that they would receive a fifth season.
