Episode seven of The Hunting Party, which aired on Monday, focuses on the capture of the serial killer, Mark Marsden, known as “The Widower,” who marries women and kills them shortly after the wedding.

At the end of the episode, Becks (Melissa Roxburgh), Jacob (Patrick Sabongui), and Oliver (Nick Wechsler) make their way to Silo 12 and make a significant discovery: inside they find the aftermath of a massacre rather than a breach. It’s also revealed that Silo 12 was the location the serial killers were brought for experimentation.

Meanwhile, when Shane (Josh McKenzie) goes to visit Pit scientist Dr. Dulles (Matt Frewer), he is barred entry as it’s been discovered he has been lying about being the man’s son.

Recently, executive producer Jake Coburn spoke with SciFi Vision about Silo 12, Shane’s deception, and more.
