The third season of Netflix's "Orange Is the New Black" ended with a lot of loose ends in the lives of the Litchfield Penitentiary inmates, leaving fans eager to watch the stories unfold in the show's upcoming season 4.

One of the story arcs that fans of the show are looking forward to is the development in Taylor Schilling's character Piper Chapman. In the first two seasons of "OITNB," Piper used to be one of the tamest inmates. But she suddenly developed into a feared leader behind bars when her used panty business began to flourish. 

By the send of season 3, Piper showed the other inmates what she is capable of if they try to do something against her by using her former lover Stella Carlin (Ruby Rose) as an example. Piper discovered that Stella stole the money that she earned from her panty business when she was about to be released from prison. She appeared to have accepted Stella's apology when caught, but Piper planted contraband items in Stella's possession so she would be transferred to the maximum security prison instead. 

Will Piper's growing confidence in doing dirty tactics inside Litchfield continue even outside the prison facility in season 4? And will Piper's other ex-girlfriend Alex Vause (Laura Prepon) allow it to happen now that it was confirmed that she will return in season 4 after she survived Lolly's (Lori Petty) bathroom attack? 

Meanwhile, viewers of the show should also look forward to a lot of new faces when the critically-acclaimed comedy-drama returns in season 4, including "Under The Dome" star Jolene Purdy. It was also reported that Flaca (Jackie Cruz) and Big Boo (Lea DeLaria) will be seen more often in the coming season. 

The filming for "Orange Is the New Black" season 4 has yet to begin, but the series is expected to be released by Netflix sometime in 2016.
