The last time we saw Sophia Burset (Laverne Cox) onOrange Is the New Black, she was being shipped off to SHU "for her own protection" after her friendship with Gloria (Selenis Leyva) soured. But is there any room for forgiveness in that relationship?

"I don't think that can be repaired," Cox tells TVGuide.com in the video above.

But while the events of Season 3 caused irreparable damage between Sophia and one of her only good prison friends, Cox is grateful to have been given the opportunity to address very real problems trans women face while incarcerated. "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 says.

According to the actress, when Orange returns this summer, the Netflix series will continue to address critical issues like this head-on. "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 says.

Orange Is the New Black returns Friday, June 17 on Netflix.
