Over the past two seasons of Netflix's hit women-in-prison series Orange Is the New Black, showrunner Jenji Kohan and company have introduced viewers to a colorful cast of incarcerated characters: pacifist nuns, nutty psychopaths, oversexed jokesters, lovesick stalkers, methhead holy rollers, transgender hairdressers and, just for variety, one über-privileged drug-smuggling WASP. We've got to meet inmates of all shapes, sizes, subcultures, and sexual preferences — making the show one of the single most diverse and inclusive TV dramas to ever grace the small screen.

But it also means that you're dealing with an ensemble cast that keeps getting larger and larger, and enough intersecting plot lines to put Game of Thrones to shame. Before Netflix drops the next batch of new episodes en toto on June 12th, you may need a refresher on who's who and what’s happening with everybody — so we're providing a quick (re)introduction to the inmates of Litchfield Penitentary. From Piper to Pennsatucky, Crazy Eyes to Big Boo, here's your one-stop OITNB MVP dossier.
