There's one massive question that goes unanswered on the new season of 'Orange Is the New Black' — here's what you need to know

Warning: This post contains major spoilers for "Orange Is the New Black."

The sixth season of "Orange Is the New Black" is now streaming on Netflix. 

If you haven't done a re-watch of season five before returning to the ladies of Litchfield and skipped the recap, you may have one massive question lingering in your head regarding Piscatella.

This is your last chance to head back before spoilers. 

After the riot on season five, the Litchfield prisoners get separated and sent to max. After they get to their destinations, they learn correctional officer Desi Piscatella was killed and that someone is going to be charged with his murder.

There’s just one problem. None of the women did it.

The mystery of who killed Piscatella hangs over the entirety of season six. Since the new 13 episodes don't offer a direct flashback of the murder in question, you may be puzzled over what happened. 

A quick reminder — Who is Piscatella?

Piscatella was the C.O. who wanted to escalate the riots and then tied up and kidnapped several of the prisoners, including Piper, Alex, and Red. In one of the series’ most difficult-to-watch moments, Piscatella scalped Red on the 10th episode of season five.

The women retaliated against him and, near the season's end, Tasha Jefferson (aka Taystee) held a gun to his head, blaming him for the death of her best friend, Poussey Washington. Ultimately, Red let's him go. 

So when and how was he killed? 

As the women let Piscatella go, a SWAT team entered the prison in riot gear. As Piscatella exits a doorway with his arms up, he gets shot dead in the eye by an inexperienced officer named Natoli. 

Piscatella's murder went unreported. On season six, the murder is trying to be pinned on Red or Taystee since the two have motives for wanting him dead. 

All 13 episodes of "Orange is the New Black" are now streaming on Netflix.
