Pip freezes after seeing the reprinted warning note and understands what it means: Elliot Ward is Unknown. In her shock, Pip concludes that Elliot is responsible for Andie Bell’s death, Sal Singh’s framing and death, and Barney’s murder.

The discovery devastates Pip because Elliot has been a trusted, fatherly figure throughout her childhood. Pip thinks back to Elliot’s kindness, family routines, jokes, gifts, and comforting gestures, and now sees them as part of a terrifying deception.

When Cara calls for Pip, Pip folds the incriminating page and hides it in her blazer pocket before returning to the kitchen. Pip lies that she has been in the toilet, sets Cara’s laptop down, and says she feels unwell and needs to study, using that excuse to leave.

Before going, Pip tries to gather more information without alarming Cara or Naomi. Pip asks where Elliot is, then casually questions why Elliot tutors and when he began, learning from Naomi that he started just over five years earlier, shortly before Naomi left for university.

Naomi notices Elliot’s car pulling up, and Pip becomes physically tense. Elliot enters moments later, cheerful and ordinary, claiming he was delayed by a long teachers’ meeting and offering Halloween potato shapes, forcing Pip to face the man she now believes is the killer while Cara and Naomi remain unaware.
