Mother's Day

S6, E25: Audrey (guest star Wynonna Judd, reprising her role) is anything but pleased when she finds Monica, Andrew and Tess on her doorstep. The last time she saw the angels was when they took her only son, Petey, up to heaven. Since that day, Audrey's been losing herself in drunken stupors trying to forget the pain in her he art. However, the angels enlist one of their own (guest star Jean Stapleton) to help when Audrey shuns an estranged woman from her past -- the only who has the power to comfort her as no one else in the world can -- her mother (guest star Naomi Judd).
