In the third season of Orange Is the New Black, which premiered on Friday, Piper Chapman is no longer be the central focus of the story. Over the course of the season, characters we haven’t heard much from before, including the soft-spoken Chang, get their backstories revealed, and new characters arrive to offer Litchfield Penitentiary more intrigue.  This has long been one of the best things about OITNB: the way it pivots from prison scenes to places on the outside—the homes, apartments, playgrounds, and schools where characters had lives before jail—then back again to the beige halls of Litchfield.
