Ryan searches for the knife

With the rest of the house asleep, Whitney finds Debra's bag containing the knife under the stairs and takes a peek inside. At that moment, there's a knock at the door but Bianca's furious that the deliveryman had the wrong house. Finding Debra waiting by the window in the living room, Bianca asks her to leave. Concerned for her own safety, Debra tells Whitney that if she goes outside and Ryan finds her, she's as good as dead. Whitney subsequently agrees to talk Bianca into letting her stay. Later, as Debra surveys the scene outside, Bianca accuses her of being a bad mother. Not wanting to argue, Debra's about to leave just as Ryan walks through the door.

Bianca's confused and asks Debra and Ryan to get out of the house, but Whitney reveals that Ryan is her half-brother. Ryan begins searching through the house for his knife, while Debra pleads ignorance as to its whereabouts. On hearing the mayhem in the kitchen, Bianca storms in and attempts to drag Debra out of the house, but Whitney convinces her that she'll sort it. Later in the café, Whitney reveals to Ryan and Debra that she's hidden the knife and won't hand it over until they sort their problems. As mother and son continue to argue, Whitney runs out. They try to convince her that they both care, but talk soon returns to the knife.

Back at the house, Bianca asks for a quiet word with Debra and Ryan and quickly accuses Debra of being a bad mother. Ryan, meanwhile, is clear - once he has what he came for, he'll leave. Whitney hears their discussion from behind the door, before locating the knife and running out with it. Bianca, Debra and Ryan try to look for Whitney, but there's no sign of her. As Debra does another runner from the Square, Whitney turns up at the canal and fills the bag containing the knife with stones and drops it into the water below…
