When does Mary Hartman, Mary Hartman return?

The series was produced by Norman Lear and starred Louise Lasser, Greg Mullavey, Dody Goodman, Norman Alden, Mary Kay Place, Graham Jarvis, Debralee Scott, and Victor Kilian. The show's title, featuring the title character's name stated twice, is a reference to Lear's observation that dialogue within soap operas tended to be repeated. The series premiered in January 1976, and was filmed at KTLA Studios in Los Angeles.
Mary Hartman's twisting, interwoven, elaborate plots and tongue-in-cheek melodrama lampooned the soap opera format in ways that set the stage for cult shows featuring plot labyrinths, like Soap and Twin Peaks. Character's key traits, unusual, but prescient for the times, include her initially numbed-out response to conflicts both external and emotional.
