Sophia Burset (Laverne Cox)
Backstory: Sophia's in the clink because of credit-card fraud, but her story is downright tragic: She's a transgender woman, and was using her ill-gotten funds in order to bankroll the surgeries and medical attention she needed. Her wife is supportive; her son, Michael, is not, and tipped the cops off to her crimes.
Place in Litchfield's hierarchy: Sophia seems to operate outside of the petty drama that consumes many of the prison's other inmates, making nice with Red, Piper, and Pennsatucky alike.
Pre-OITNB: In 2008, Cox was one of 13 contestants on the first season of VH1's I Want to Work For Diddy. Though she didn't win, it led to a gig hosting and producing the makeover show TRANSform ME, with Cox and two other transgender women doling out beauty and life advice to cisgender women.
Best line: "I knew them bitches was lying when they said you left here looking like Omar from The Wire."
