The episode ends with Jenn getting a call from the hostel. A young woman has just checked in using a fake name: "Erin Townsend" – Jenn's estranged daughter, whom she gave up for adoption 17 years ago and never told anyone about, not even her current family.
Meanwhile, Jenn's own family drama escalates. Her son, Conor, is caught shoplifting again, and her ex-husband, Andy, uses it to threaten custody. But the bigger shock: Jenn's father, Billy Townsend , shows up unannounced at her house. He's been out of prison for six months (she didn't know he was released). He asks for money, and when she refuses, he storms off.
Jenn and Med raid the farm at dusk. In the barn, they find Leah's phone and a bloodied tarpaulin – but also another girl, Chloe (16) , locked in a root cellar. Chloe whispers that Marcus "got rid of Leah because she was going to talk."
The victim is identified as Leah Sumner , a 22-year-old care leaver who worked at a local arcade and lived in a hostel. Jenn visits the hostel and finds her room ransacked. The manager admits that Leah owed money to a loan shark named Col "The Fish" Farley .
