Sophia was last seen being ushered away to SHU after a fight broke out between her and Gloria. Cox spoke about this shining a spotlight on the issues many trans women face in prison.

"The reasons of why Sophia ended up in solitary, the violence that she experienced, that violence is a reality for far too many people who are incarcerated, particularly trans women who are far too often incarcerated in men's prisons," Cox noted.

While Cox was coy about divulging any new details about season 4, she did speak on the broader theme taking place for the upcoming season.

"What's exciting in Season 4 is that I believe our writers go even deeper into some pertinent issues that affect folks who are incarcerated," she teased.

OITNB has never been shy about portraying the psychological effects and corruption involved in the prison system.

Orange Is the New Black season 4 drops on Friday, June 17 on Netflix.
