Who's in the Orange cast this season?
Let's break it down into "extremely likely" and "less likely." You can expect the core group of inmates left in the bunker -- Piper (Taylor Schilling), Alex (Laura Prepon), Taystee (Danielle Brooks), Red (Kate Mulgrew), Nicky (Natasha Lyonne), Frieda (Dale Soules), Suzanne (Uzo Aduba), Cindy (Adrienne C. Moore), Gloria (Selenis Leyva), and Blanca (Laura Gomez) -- to return. (Safe bet, as many of them have posted set pics.) You can also permanently forget about the dead idiots known as Piscatella (Brad William Henke) and Humphrey (Michael Torpey). They're out.
The others? Less obvious.
OITNB's Season 5 finale was set so the show could be revamped however needed. This means, given the bus cliffhanger and some of the other loose ends, you might not see the more fringe characters as much, or at all. Daya, for example, "just committed a crime (and) obviously that will be punished," Dascha Polanco, who plays Daya, told USA Today. "You might not see her ever again." Caputo (Nick Sandow), who, you know, ran a prison that got overtaken by inmates, also seems like he could be out of a job. Then there's Pennsatucky (Taryn Manning) and Mei Chang (Lori Tan Chinn), two faves whose futures are up in the air given their escapes.
