Episode 6 starts with “12 hours ago”, where we assume someone has been seriously injured. The group flees Clara’s domain, but it’s a fight. Riley drives onto the main road and sends a message to the team explaining she’s gone, but someone in a truck tries to run over her. She gets hit by the truck, so she hides in the woods; Riley tries to call her mother for help. But it’s too late. A knife impales him from behind.
Episode 6 then turns into a flashback with Riley and Dylan at a house party, but he is distracted by the twins. Riley feels his distraction. In the present, concerns begin to spread when Riley and Dylan’s mother has no idea where Riley is. The mother goes to the police station because she is worried. There’s nothing official that can happen unless she’s gone missing for 48 hours. In addition, the police are very concerned about native spiders. In a flashback, Riley sees Dylan going to the party with Lennon, and she is out of breath. Today, friends get together and worry about Riley.
While searching for Riley, Dylan tells Lennon (Allison) that he was in love with her on graduation night, but that he loves Allison. But before they can continue the conversation, they are shocked to find Riley’s arm, but not her body, meaning she may still be alive. Meanwhile, Bruce confronts Clara and tells her that the police know about her spiders. Clara tells Bruce that he has no authority here and that his secrets will still be there even if she isn’t there.
The friends know they have to go back to the estate to find Riley, but they get a location ping from Riley’s phone. Meanwhile, the mother continues to look for her. The mother finds Riley’s phone, but it’s a trap, and it hangs by the neck of a backhoe. Another one that bites the dust. The friends love another place by the sea, then they receive a text message challenging them. They assume the worst: that Riley is dead. However, the episode flies off for Riley. She is still alive at the moment. The police go to Clara’s domain regarding the spiders, but they soon find Riley’s mother dead. The situation is more serious than they thought.
Secrets are revealed in episode 6, which deals a devastating blow to Allison. Bruce confronts Allison and he knows she knows he was married to Clara. He then reveals that his mother is living in a shock bomb. Bruce doesn’t want any more secrets between them. Allison has lived her entire life believing her mother committed suicide and is distraught. Bruce then thought it was better to lie down because his mother didn’t want to be part of the family. Bruce mentions the cult and how Fred Phillips got in touch. Allison puts the pieces together – what her sister knew is why they argued at the party that night. Bruce then reveals that he threw his sister out of his car the night she was run over.
