When does Joan of Arcadia return?

The series originally aired on Fridays on CBS for two seasons, from September 26, 2003, to April 22, 2005. The title alludes to Joan of Arc and the show takes place in a fictionalized version of the town Arcadia, Maryland. The series examines God from a more metaphysical standpoint instead of a religious perspective.
Joan Girardi is a 16-year-old teenager living in the town of Arcadia in Maryland. She is the middle child of her family which includes elder brother Kevin, a former jock who has been left a paraplegic after a car accident, and younger brother Luke, a brainy nerd. Joan is asked by God to perform tasks that often appear to be trivial or inconsequential but always end up positively improving a larger situation.
