'Orange is the New Black' release date, plot spoilers: Kate Mulgrew hints 'very dark' season 4; Alex-Piper-Stella love triangle to continue?

One of Netflix's most popular series "Orange is the New Black" returns for its fourth episode this June, and more twists and turns are in store for the ladies of Litchfield.

The show ended its third season with Piper Chapman (Taylor Schilling) metaphorically kicking Stella (Ruby Rose) where it hurts, as Piper had her sent to max. Fans speculate that Stella is out to get Piper for revenge, but it's still unclear if Alex Vause (Laura Prepon) will stand by her after everything that happened in their tumultuous on-and-off relationship.

Kate Mulgrew, who plays the role of Red, recently teased about next season during a Netflix press event in Paris.
