Ex-Nickelodeon stars still have more to say following the premiere of "Quiet on Set: The Dark Side of Kids TV," the docuseries that shocked and disturbed many of its 16 million viewers.

Released in two parts on March 17 and 18, the tell-all documentary takes viewers behind the scenes of some of Nickelodeon's biggest television shows of the 1990s and 2000s, revealing the allegedly toxic and abusive environment that was cultivated behind the scenes by adults at the network, including Brian Peck, who served jail time for his sexual abuse of teen star Drake Bell.

The four-part docuseries covered a lot of ground, revealing previously sealed court documents and interviews with stars sharing their stories publicly for the first time.

Now, Investigation Discovery has announced the pending release of a previously unannounced fifth episode. According to the network, the surprise additional installment will delve even further into the details of the stories told in the main doc and feature more interviews with people who participated and new voices alike.

Here's what we know about the fifth episode of "Quiet on Set."
