Sick from her bullet wound and mistrustful of her colleagues, Nancy desperately needs an ally - but she can't open up to Hayley for fear of putting them both in danger. When the police make a public appeal hoping to shake out the missing witness, Nancy is unexpectedly forced into the spotlight, leaving her exposed and bringing an old enemy out of the woodwork - Hayley's ex-boyfriend, Shay Nash.

After her near-miss with Gunner, Nancy is challenged by Newman. She's treading a dangerous line and is in jeopardy of being exposed – until O'Dowd steps in to help. He tells Nancy that they must work in tandem, and together they question Nash. But Nancy's no nearer to finding out who's pulling the strings.
